Curb Appeal Take V – Landscaping Our Front Yard

Are you ready for more gardening projects on TerrificBroth? Better buckle up, because we are!

A few weeks ago, we attended a water wise gardening seminar and registered for a free landscaping consultation at the end. We needed some advice on our front yard, which was covered in bindweeds and dying lawn grass when we moved in:

IMG_7859

IMG_7873

We made some improvement to the front of the house during the past year. But the lawn is still in bad shape despite thousands gallons of water we gave it:

IMG_3989

As you can see from the first photo or in this video, our front yard slopes down on the north side. The slope starts fairly gentle but becomes quite significant over the last 40 feet.

IMG_7853

Facing west and sloping down to the north, this front yard is beaten down by strong afternoon sun and northwest wind. It did not stand a chance.

IMG_3991

From a whole year of watering, weeding, and mowing this slope, we knew that we did not have the energy to keep up. We want our front yard to look good, but we also need it to be low-maintenance. More importantly, we need it to use less water than it does now.  So, when the landscape consultant came to our house, I only have one question – what should I plant in place of grass in our front yard?

The landscape consultant was pleasantly surprised by my question. She was probably expecting me to ask her how to keep the lawn green, which most of the people would desire. As most of the landscaping experts in Denver area, she prefers xeriscape and is good at designing urban spaces using xeriscape principles. But most of the time, her clients prefers green turf which is usually water-thirsty. Especially if HOA is involved. Most of the time, the best she could do is to suggest a relatively drought tolerant grass to put in.

Although unexpected, she quickly adjusted to my question and started giving me a bunch of plant names. I did not want to just cover everything with rocks and succulents – we still appreciate flowers and soft texture, and we want our garden to be a refuge for pollinators, birds, and insects. With birds and bees in mind, we spent almost an hour chatting about plants and ended up with a solid planting map at the end:

Landscape

This plan calls for the removal of 600 sqft turf, almost half of our front yard, and replace it with perennials and evergreens. We will also be putting in a dry creek to redirect the rain water from our downspout to the new garden space (labeled as “11” in the sketch below).

So what are we planting here? Let me break down the plan for you. If you are a plant freak like me, I can hear your heart racing.

First, the blue in the sketch above is our house and driveway, and all the circles will be plants. This sketch has west at the top, so this new garden will occupy the northwest half of our front yard and butts against our future front fence. The boundary was drawn arbitrarily; it most followed the line along which the slope became steep towards the streets to the west (up) and our neighbor’s driveway to the north (right).

1 Windbreakers

The first order of business is to create a wind barrier for this slope. We get really strong north/northwest wind coming from the Rockies during all four seasons, and our house does not have any tall structure on its north/northwest to slow down the wind. On a slope like ours, the wind travels upward and sucks away all the moisture in the top soil, making the clay harder and more compact. Generally speaking, two practices are recommended for combating drying wind – mulch heavily, and plant tall trees on the north side as a windbreaker. And we will be doing both.

To create a wind barrier, we chose to plant six arborvitaes along the north side of the yard, aligning our neighbor’s driveway. Planting a tall hedge there will not only slow down the wind, but also conceal the cars filling up the driveway everyday.

IMG_3987

After some research, I chose the “North Pole” arborvitae for its winter hardiness and soft look. I ordered six of them and they arrived quickly and soundly.

IMG_3986

2. A Corner Anchor

Lanscape design_with labels

The six arborvitae are expected to run 3/4 of the northern side. For the corner, I prefer something softer than an evergreen, a flowering plant with a decent height. Having lived in SoCal I have missed the smell of citrus blooms. So mock orange became an easy choice for this corner. I chose a compact variety called Snow White Sensation, which gives pure white and double flowers.

3. Winter interests and Food for Birds

Most of the trees in our neighborhood are deciduous trees, which means that they lose their leaves in winter. From December to April, for five months, everything looks dead and it is really depressing. I crave more winter interests.

Lanscape design_with labels

The arborvitaes we bought are evergreens; they will be bright and soft green during winter months. We have two existing pine trees that have dark green needles. To add some red, I decided to use three winter berries called “Berry Poppins”.  These berry shrubs are known for their bright red berries which last entire winter until early spring. which can be a steady food supply for hungry birds. Also, they look incredible against snow.

Berry Poppins® - Winterberry - Ilex verticillata

These berries needs both male and female plants to bear fruit, so I also purchased a male plant “Mr. Poppins”. The male plant will not bear fruit, but it will flower in Spring for some Spring/Summer interests.

4. Xeriscape Perennials for Pollinators

The mock orange, evergreen hedge, and winter berries are the bigger and anchor pieces in this design. Although they together attenuate the northwest wind, they are not xeriscape plants. Therefore, for the rest of the garden covering the slope, we chose all drought-tolerate plants including perennial flowers and shrubs. I had such a good success with the garden-in-a-box from Resource Central this Spring – the one I got is called honeybee heaven and it attracts bumblebees and mason bees like crazy – that I decided to purchase another one of their fall gardens for this space. The garden kit I ordered is called “Cool Connection”, which includes 23 plants – such as penstemon, dwarf larkspur, and Salvia. These plants are not only drought tolerant but also hummingbird- and butterfly-friendly.

Lanscape design_with labels

In the planting map above, the penstemon, the dwarf blue larkspur, and the rose queen Salvia will be planted in the red triangle labeled as “8”. This garden kits provide three of each plants so they will be planted as clusters. I adore the color of these plants – they mostly bloom pinks, purples, and blues, hence the name “Cool Connection”.

The kit also provides three Butterfly weeds. I will likely put them in where the red circle labeled as 8 with a double bubblemint hyssop which blooms pink (also included in the garden kit).

5. Adding Soft Texture with Grasses

Next to the perennial flowers we will be adding some grasses. Blue grama grass is Colorado’s state grass, whose seed packets last entire winter and are an excellent food source for small birds.

The garden kits includes three of them, along with three switch grass which is a popular roadside plant in the Denver area. These grass are practically zero-water plants after the first year, and their long-lasting foliage provide shelters for small birds and insects in Winter months.  They will be planted in green triangles labeled as “7”.

Lanscape design_with labels

Also will be planted in area “7” are a couple of blue oat grasses. If you have not heard blue oat grass, or blue avena grass, definitely check it out. It has beautiful blue blades and its upright form just looks so perky.

6. Trying out New Shrubs!

OK by this time if you are still reading, I am impressed. We are more than half way there. I promise. If you think this garden is pretty full, keep in mind that we have 600~700 sqft to fill! In addition to flowers, I also need low growing shrubs and ground covers. One plant the landscaping consultant highly recommended is sandcherry, which is a native plant that bear edible fruits in late summer. It also has a striking red foliage in the Fall. I have never had sand cherry before. But I figured that I could always leave them for wildlife if I do not fond the flavor.

The sandberry will be planted in the circle labeled as “6”, and “4” will be a dwarf mugo pine. We have two pine trees already in our front yard but they look very different. And this dwaft mugo pine will look completely different from either of them. It has short branches and low to the ground, but it will bear tiny cones on the tip of the upright branches. A cutie indeed.

7. Boulders and Groundcovers

Lanscape design_with labels

Aside from everything I’ve named, we will use boulder rocks (the “5”s) and groundcover plants sparsely. Groundcover (the “10”‘s) is a great way to keep the soil cool and moist. It is more attractive to mulch and can spread and spill over boulders for a more dramatic effect. The garden kit I mentioned above includes some ground covers such as Prairie Winecups. I also got some sedum, veronica, and creeping phlox from a local nursery.

IMG_4010

8. My First Irises

The last category of plants in this front yard will be irises. I have never had irises before and am dying to give it a try. They do excellent in our area – one neighbor has dozens of them in his front yard and they made a big statement in the Spring. I ordered some purple ones and white ones, and plan to tuck them in here and there to add some height (for example, in area labeled as “9”). I may have ordered too many, but I can always plant them in the backyard for some cut flowers.

9. Planting Progress

If you are wondering what we have been doing these past a couple weeks, now you know! I’ve been hunting down plants, while Slav has been digging in the front yard to remove all the sod. We even have some plants in the ground already!

The winter berries arrived first. They are tiny now but they will grow to 4 feet wide /tall and fill in eventually.

IMG_3994

Yesterday, we got all six arborvitaes into the ground:

IMG_4004

IMG_4005

They are a bit root bound but otherwise very healthy. I broke open the old roots and planted them with lots of good compost. These trees are already 3 feet tall and they are supposed to grow a few inches each year.

IMG_4019

Most of the perennials we ordered will come in late August and late September. To prepare for planting, Slav removed all the sod and turned the soil.

IMG_4024

IMG_4027

IMG_4026

IMG_4036

IMG_4042

He did a really good job edging the grass. We will install the same plastic edging I used in the backyard to separate the flower beds and the grass.

IMG_4000

While we were getting the edging from Home Depot I saw a mugo pine. It is actually hard to hunt down online so of course it came home with us:

IMG_4038

Isn’t it cute?

IMG_4039

We are working on getting this big planting area prepared for fall planting, and we need to figure out a way to retain soil and mulch so they do not spill over the sidewalk every time it rains. Although right now our front yard looks like a mud pit, I think it still looked better than dead grass – at lease you can tell it is renovated! I knew that after all the planting in fall, this yard will be so different for so much better! So stay tuned, friends!

Garden Edging Continued | Perennial Bed Borders

“Spring is for planting, summer is for building, fall is for harvesting, and winter is for resting.” – Fouch Family Off Grid

One of my favorite homestead family, Fouch Family Off Grid, brilliantly summarized what the four seasons are like for their off-grid homestead. Although being city dwellers, we very much follow the same pattern. Except for us, the winter is for playing – in the snow.

This spring is our first in the ranch house. We planted, planted, and planted more. I had dirt under my finger nails for three months during which I presented at three conference meetings. Now summer rolls around, it is finally time to start building.

Edging project I: Honeybee’s heaven perennial bed

This past week was dedicated to garden edging. Garden edging is part of the hardscape and can be used to define an outdoor area or a flower bed. It is also a good way to keep the soil or mulch contained and the weeds out out of a flower bed. I initially went for soft edging, which means no physical boundary but mulching over the flower beds.

IMG_3501

It did not work very well for us because all the weeds were climbing into the bed.

IMG_3505

Not only the soft edging invited weeds, it also created problem for Slav who mows our lawn. The hedge trimmer hit the wood chips hard and and broke them into pieces. Some of them flew high in the air and even hit Slav’s face.

Here is an unspoken rule in our family: we try to make each other’s life easier. Slav takes out the recycle, so I make sure to flatten the cardbox boxes before putting them into the bins. I compost, so Slav chops kitchen scrapes fine so they break down faster. We are free to do whatever we want and however we want, but one’s action should not make the other’s household tasks more difficult. Although the consequence of my choice of soft edging was not immediately apparent, watching woodchips hitting Slav’s face was an implicit reminder that I needed to change things up.

IMG_3500

Edging can be done in different ways and with different materials – plastic, metal, brick, concrete, etc. You can see both plastic and concrete pavers against the flower bed below. I recently installed the same plastic garden edging along the back fence and really liked the look of it. But I do not think it is a good choice for edging this perennial bed. First, they are soft and cannot hold a perfect line by its own. Installing them against a relative straight fence avoids the problem, but they may appear wavy around a free-standing flower bed. Second, their primary function is to prevent root crossing and are meant to be installed deep into the soil. But the mulch in our flower bed was a couple inches above the ground so I want the edging to also be raised. Third, the plastic edging may not stand well to the blades of lawn mowers. Last, the main goal here is to create a wide separation between the wood chips and the grass, so I decided to use the concrete pavers, or more specifically, the concrete edgers.

IMG_3495

But first, look at how well everything is growing! This is the garden-in-a-box kit called “honeybee’s heaven” we planted early May. In just 6 weeks, everything has grown to 4x of their original size and all of the plants flowered. Thumbs up for native plants!

Saturday morning @ my #pollinatorgarden arden. #gardening #savethebees🐝

A post shared by Terrific Broth (@terrificbroth) on

Such pretty garden deserves a good edging – an expensive one. These edgers are not cheap, about $2.58 a pop that only lines 0.8 linear feet (in contrast the plastic edging was $28 for 60 feet!) But the edger blocks are wide and tall, perfect for blocking the root from crossing underground while leaving enough height to keep the mulch in. Slav kindly picked up 50 of them for me – they are so heavy that I could only transfer 8 pieces a time using the wheelbarrow! But I am glad they are because it means that they can stand by themselves without additional reinforcement.

IMG_3494

I started by laying them out to create a curve I like then started digging into the ground along the curve. A whole week of rain made digging a breeze.

IMG_3510

Then I set the edgers in. I used native soil to bump up the concrete edgers a bit, until they sat a few inches above the soil and level. These edgers have curves on both ends, so it was easy to form a nice curve without much gap in between. I actually lay them on their sides because I like the height and the look much better.

IMG_3513

To be clear, setting pavers are usually much more involved than the way I did it. Especially if you are creating a patio or a walk pass. This is a good article describing how garden edging using pavers should be done. I you are up for a permanent edging task or a surface that will be walked on, I high recommend that you follow these steps. It requires paver base, stone dust, sand, and a lot more leveling and compacting, but the end result will be permanent and perfectly level. For my flower bed I chose the sloppy way. Our perennial bed may not be permanent and its shape may change in upcoming years, so I do not want to anything permanent. Besides, our lawn mower is not going to ride on top of this edging but next to it, so it does not need to be perfectly level.

IMG_3514

This is the finished product and I like it. It does a great job holding all the mulch in, and I like how polished it made the bed look. The grey color ties into our back patio so, so well. And the best thing is, Slav can now use the hedge trimmer right against the garden bed without worrying about flying woodchips!

IMG_3516

Edging project II: Underplanting perennial garden

In this spirit I also installed the same edgers around the other perennial bed in our backyard, right under our crab apple tree. I used to have branches right against the bed as a natural edger and I absolutely adore it. But again it did not work well for mowing.

IMG_3523

In the process I made the bed larger. The crab apple tree shades everything below so the poor flowers are not growing as well as I hoped. We need to plant something else next year and a bigger bed will allow me to have both shade and partial shade plants here.

IMG_3534

Here is the bed when I finished:

IMG_3541

IMG_3542

IMG_3549

I like the result a lot more than I thought. Maybe because of the messy edge of the pavers, the bed does not feel too serious. I also like how the same concrete edger ties the two beds together. They echo the color of our concrete patio which downplayed their existence. I do not find them intruding at all.

IMG_3539

As you can see we have drip tubing runs in and out of this bed. We will bury them as some point so Slav can push the lawn mower through this area, probably next year after we set up all the veggie beds.

Edging project III: Frontyard mailbox underplanting

Next we moved onto edging the last perennial flower bed. This bed is in our front yard and directly under our mail box.

IMG_2088

Our black metal mailbox is very boring and I think the underplanting complements it nicely – a boring rectangle with just a few plants in it. There is one lavender, two rosemary bushes, and a struggling rose:

IMG_3581

This poor rose. We’ve got bunnies in this neighborhood and they love this rose bush, or more accurately, the taste of it. Every a few days I find the new growth on this rose leveled to the ground. Thankfully these bunnies are as dumb as their cotton tails are cute – they have not discovered my salad garden yet (knock on wood).

Although uninspiring, it is still a big upgrade compared to the weeds and broken bricks we inherited:

IMG_6456

For this bed I decided to create a mowing strip. Mowing strips are usually done with brick pavers. I chose to build one that is composed of two lines of bricks, one line on their side and the other laying flat. The taller edge keeps the mulch in while the flat part is leveled with the turf for the lawnmower to ride on.

To build this mowing strip I more or less followed the instructions here. Again, I did not use paver base or stone dust or any form of underlayment, because I do not know how permanent this flower bed will be. I simply dug down, leveled the brick with native dirt, laid bricks in, and packed around them with soil. I brushed some play sand in between the bricks to fill the gap so grass will not find their way into the flower bed.

IMG_3577

This brick paver is purposely different from the concrete grey ones I used in the backyard. I want to make the edging in the front yard more formal while keeping the backyard look more natural. This brick is super flat with sharp edges, making leveling them with the grass pretty easy.

The new border feels like the way it should have always been. I like the width and how it fills the void lawn a bit. As you may have noticed, we also made it bigger for more planting area. I want to add some winter interest plants here so from November to April our yard does not look super dead.

IMG_3576

Mulch!

As the final step of polishing everything up, we proceeded to mulch. Mulch is great for weed control and in our area, it is also crucial for reducing surface evaporation and keeping soil cooler. We have really bad problem with weeds especially where we water often, such as around the veggie beds:

IMG_3526

We could hardly see where the veggie beds end and where the weeds start. In preparation for mulching, I pulled most of weeds out, cut the grass super short, and covered all the path in between and around the veggie beds with heavy duty cardboard.

After weeding and mowing:

IMG_3529

Slav brought in two full trailer loads of wood chips and we mulched in between and all around the veggie beds:

IMG_3561

IMG_3566

Doesn’t the mulch make everything look sharper? I could not be happier. Some of these wood chips are from fresh-chipped pine trees and they smell AMAZING. We continued the mulch along the back fence around the fruit trees and roses. This is another area I had been weeding by hand since this Spring, which took a few hours per week. With all the mulching we have replaced ~1000 sqft of the lawn that needs weeding and mowing constantly. Cutting down maintenance time while saving water sounds like a win-win to me.

IMG_3551

Here you have it, all three flower beds edged, large area mulched, and my landscaper (Slav) is happy. And guess who else is happy? These roses.

IMG_3559

Happy summer!

My First Rose | How to Install Plastic Garden Edging

I am always drawn to English cottage gardens – green hedges, lush garden beds filled with cut flowers, and roses and peonies wherever possible.

Tasha Tudor’s Garden

I want my garden to be informal but intentional – a bit messy. In this spirit, I’ve chosen to plant perennial flowers and blending them in with the surroundings with nature-looking wood mulch.

IMG_3342

IMG_3058

We also plan to grow evergreen hedges. If you remember our backyard layout, we neighbors four properties with long stretch of fences that needs to be covered.

07

IMG_3071

I always knew our back fence will be the perfect place for a wall of climbing roses. It is west-facing and the majority of the fence receives full sun, ideal for growing roses. We have planted five fruit trees that will form canopies above the fence in a few years, but in between we could really use some green foliage and soft flowers.

IMG_3430

Choosing the right rose

After weeks of research, I finally pulled the trigger and got four climbing roses from a local nursery. High Country Roses specializes on cold-hardy roses that grows well in Colorado, where high altitude, high winds, and clay soil take a toll on regular varieties. I have learned that from the veggie garden that we have to plant the specialty plants selected for our harsh climate. The regulars just do not stick. 

IMG_3405

The climbing roses we got are called Awakening. It is a sport of New Dawn, one of the most popular David Austin Rose. Reportedly, Awakening has all the advantages of New Dawn, including the glossy foliage, light apple scent, subtle pink and white blooms, but they grow faster and bloom better (more repeat) than New Dawn.

Awakening:

Its parent flower: New Dawn

As you can see, Awakening also offers more petals per flower, a softer look I am after. Our yard and house are rectangle-shaped and look very stiff. I could use some bendy canes, layered pink pedals, and curved garden beds to break up the rectangles. During weeks of research I have not read a single complaint about Awakening, except it grows faster and bigger than many would think. The decision was made easy.

I brought them back from the nursery and left them our in partially shaded area for a few days to harden off:

IMG_3407

This is the look I am after:

Before planting, I still needed to tackle a few tasks in the area, including removing the open yard compost along the back fence, and edging along the pickets.

Edging along the fence

IMG_3433

As you can see, our yard slopes down towards the fence. Understandably there is a lot of soil build up against it:

IMG_3434

The metal edging installed along the fence have been pushed around by the soil and do not protect the fence from touching the soil anymore.

IMG_3435

IMG_3438

IMG_3440

Behind the fence there is a retaining wall, a few feet above neighbor’s yard. Preventing top soil from pilling up against the retaining wall is important for its integrity. So we really needed to refresh the edging before planting.

IMG_3450

I started by digging along the fence and pulling out all the old metal edging. You can see some was already pushed into the other side of the fence.

IMG_3443

After pulling every pieces of metal out, I was happy to find 6-mil poly (not landscape fabric) laid in our retaining wall on the other side of the fence. We have been wanting to come over to our neighbors to clean up the retaining wall since we moved in. Years of neglect granted it to be a shallow trash can and home for some happy weeds. Knowing that all that are only floating on the very surface above the plastic is comforting.

IMG_3452

Our back fence is 88 feet long so it took me a few hours to remove all the old metal edging and dig down until all the pickets were shown. The edging needed to be installed against and just below the fence, so no soil will ever be in contact with the pickets.

IMG_3458

IMG_3464

We got the cheapest plastic edging from Home Depot. It is about $28 for 60 feet and we got two. They are also the tallest – about 5″. I want them to come above the soil a bit so we can mulch the area.

IMG_3461

According to instructions, I laid them flat under the sun for a day or so to soften them up. They were very easy to manipulate after that.

IMG_3428

IMG_3441

I leaned the edging against the fence, made sure that the bottom of the edging sit just below the bottom of the pickets, and buried them with dirt.

IMG_3455

IMG_3466

IMG_3468

One of the complaints about this particular edging is that it is too soft to hold a straight line. It was not a problem in this project since I was putting it up again a relatively straight fence.

IMG_3469

Each roll of the edging is 60 feet, so for our 88 feet fence, I needed to join two together. Each roll of the edging came with a connector which made the seam tight and hardly noticeable.

IMG_3470

This is the finished look and I am very happy with it. The new black edging made the fence look more polished and a whole lotta sharper.

IMG_3474

IMG_3476

Planting the Roses

The last task before planting the roses was to move the morning glory I previously planted along the fence.

IMG_3442

They came up from seeds I planted mid-May and really should have grown bigger by this point. 🙁 They are getting another chance at the corners of the back fence.

IMG_3485

While digging the morning glories out I was happy to see abundant of earth worms below. We have been piling up fall leaves and glass trimmings the back fence since last fall, 6 months till now. It was such a success. I did not cover, water, or turn them at all – just pile new stuff on top of the old. But all the fall leaves were completely broken down and mixed into the top soil thanks to the earth worms.

IMG_3477

All the open compost were transferred to the new veggie beds and roses were planted into the now rich top soil.

IMG_3480

IMG_3489

IMG_3483

We piled some wood chips we produced ourselves around the rose and watered them in. Now we wait! I do not expect much bloom this summer but hope to see some foliage. And I desperately need to learn how to care for these pretty babies. Should I stake the canes? Should I fertilize again? Should wait a few years before training the canes? I want pretty trellis that is self-supporting but invisible. which kind should I get? If you have experience growing and training climbing roses, or building garden trellis, I would love your advice!
