I’m back with design notes from the field, where I share observations and recommendations from my work as a landscape consultant. This edition features a new build, metal art, weeds, and shade. I hope that you can pick out helpful tips that you can use in your landscape.

Up first, is a new house that is being constructed in east-central Phoenix. The home that used to stand on this lot was taken down to the foundation and an energy-efficient home is coming up in its place. I was hired by the architect to design a landscape that will fit its clean, modern lines.

Several years ago, I solely worked as a landscape designer, working with homebuilders, creating new landscapes from scratch with a blank palette. Nowadays, as a landscape consultant design is just one aspect of what I do as part of an overall plan within an existing landscape, which also includes maintenance recommendations. Now and then, I create one for new homes, and this one has some fun challenges.

The look the architect wants is simple and uncluttered with room for the new homeowner to add to it if desired. So, I am concentrating on using plants to create a framework. This includes two trees in the front along with two along the west-facing side to provide screening from the road and protection from afternoon sun.

Foundation plants will soften the base of the house while taller shrubs will soften the corners. Ground covers will add low-level interest along with a few agave and cactuses for an accent.

A splash of color will be added by the front entry with the placement of a large, colorful pot filled with an easy to care for succulent.

Often, I am asked for advice on what to do in somewhat unique situations. In this case, the homeowner needed advice for what to do for the wall behind the BBQ, which keeps turning black after grilling. 

I tend to look at problems like this as opportunities for adding more interest to the outdoor space. In this case, I recommended adding garden art in the form of rusted metal botanical panels. There is a local artist in Phoenix who creates metal panels with plant shapes cut out of them. He offers standard pieces but also does custom work. 

The rusted metal garden art will add welcome interest behind the BBQ as well as disguise any blackened area on the wall.

Here is an example of the metal botanical panels from another client’s home, which was where I first encountered the work of this artist. You can learn more about this metal artist here

Weeds will always be a problem in the landscape, like these I saw at a client’s home growing through the patio. The solution to this area is to slowly pour boiling water on weeds growing through the cracks, which will kill them. For travertine, only do this if the stone is sealed. 

To wrap our design notes, here is a landscape where the homeowner wanted to concentrate on plants up close to the house and not add any further out. Now if this front yard didn’t have any trees, the absence of plants would cause it to look barren and washed out. However, the patterns from the branches of the ‘Desert Museum’ palo verde add beautiful patterns on the ground, so you can get away with leaving it bare, which draws attention to the lovely shadows of the branches.

I hope you have enjoyed this latest session of design notes. I’ll have more for you in the future.

**Stay tuned for a special announcement that I’ll be making the beginning of September. I’m working on a new project that will enable me to help you even more to create, grow, and maintain a beautiful outdoor space in the desert. I’ve been working on it for a while and am so excited to share it with you soon!

My garden has been transformed with yellow showers of flowers, courtesy of my palo verde trees. It’s a delightful time of year with warm spring temperatures and colorful landscapes filled with flowering shrub, perennials, and trees.

However, nothing heralds the arrival of spring in the desert Southwest like the golden yellow flowers of palo verde trees. I have three ‘Desert Musuem’ palo verde trees spread throughout my garden – one in the front, in the side garden (our dog run), and in the backyard.

 

The flowers do spread everywhere, which bothers some people, but I like to focus on the lovely yellow flowers transform things in the garden, like my artichoke agave where the flowers nestle inside its rosette.

 


One of my favorite views of the garden is looking out the patio door to the side garden where the branches of my palo verde tree frame the view.

There are several different species of palo verde and each one has a slightly different color flower, form the pale yellow of the foothills palo verde (Parkinsonia microphylla) to the deep yellow of ‘Desert Museum’ (Parkinsonia hybrid ‘Desert Museum’).

Here is more information about palo verde trees from an earlier post. Do you enjoy the blooms of palo verde trees?

I love using color in the garden, which is why I welcomed the opportunity to review the book, ‘The Colorful Dry Garden‘ and host a giveaway.

In my work as a horticulturist and landscape consultant, I find that people often have the mistaken impression that desert landscapes are destined to be brown and barren, but nothing could be farther from the truth. There are many plants that offer vibrant color to outdoor spaces while thriving in an arid climate.

Horticulturist, Maureen Gilmer, makes her home in the Palm Springs area, in the midst of the California desert, and she has put offered her expertise in creating colorful dry gardens in her latest book.

Her book is broken up into two different parts, with the first taking you through the steps of how to convert your landscape into one that saves water. Whether you want to do a total renovation or do it in phases, the book provides you with helpful guidance.

Part two has a comprehensive list of plants that add welcome color to the arid landscape. However, unlike many plant lists, the author groups plants into groups that focus on their role in the garden such as structure (shrubs), canopy (trees), accent plants, and those that add beautiful texture.

I have reviewed a large number of books that deal with gardening in a dry climate and ‘The Colorful Dry Garden’ approaches it a bit differently by focusing on color, design, plant function, as well as real steps on how to transition your landscape to one filled with water-saving, colorful plants.  

I enjoyed reading through the book and feel that it deserves a spot in your garden library. 

**The folks at Sasquatch Books are giving away a free copy of ‘The Colorful Dry Garden’ for readers of my blog. To enter, leave a comment telling me what your favorite colorful plant is. I will announce the winner on March 22nd.

As the garden begins to awaken in spring, our thoughts turn to getting our plants ready for the growing season, which often involves pruning.

There are different types of pruning, each of which, are used to accomplish particular results, ultimately keeping your plants attractive and healthy.

If you are learning how to prune your trees and shrubs yourself, it’s especially important to learn about the various ways of pruning to help you determine which way(s) are the best to employ.

To do this, let’s talk about the definitions for common pruning terms so you can choose the right method for your trees and shrubs. I break it all down for you in my latest article for Houzz.

Palo Blanco (Acacia willardiana)

Today’s post is written by guest blogger, Emily, who writes about sustainable gardening.

Getting to landscape your own yard is exciting, and it can prove to be really fun! You can decorate your yard with the plants you love in whatever way you want them to look. There’s no end to all the ways that plants can bring life and beauty to your backyard, but what types of plants you have to choose from can be narrowed down because of where you live.

Even beginner gardeners know that plants are affected by the amount of sunlight and kinds of temperatures they deal with on a regular basis. Some plants do better in warmer climates than others. If you live in the southwest, you know that hot, dry weather is something your plants are going to have to be prepared for. Check out some of the best trees you can pick from for your yard that will thrive in the rising temperatures of the southwest.

Your Best Options

This tree list is for those who want to look through a list of potential trees without having to do a bunch of research and get disappointed when they find out that the tree they like won’t work in their yard. Extreme heat doesn’t mean that you’re limited to only a few kinds of trees. You can have large, beautiful trees that have thick foliage and provide lots of shade. You can also have fruit trees if you’re interested in growing your own food. Read on to see which trees might fit with what you’re looking for.

Stately pine trees along a historic Phoenix street

  • Aleppo Pine – Choosing to grow the Aleppo pine might be right for you if you’re looking for an ornamental tree. It has a distinct trunk and can grow up to 80 feet tall. This tree is a great addition to a yard that looks like it’s missing some character.

Desert Willow (Chilopsis linearis)

Willow Acacia (Acacia salicina)

  • Acacia Tree – If you’re looking for a tree that’ll grow quickly, the Acacia might be for you. These trees are bright with green, yellow or white colors and live for around 20-30 years. They’re also known for stabilizing soil with their roots, which is perfect for erosion-prone areas.

Texas Mountain Laurel (Sophora secundiflora)

  • Texas Mountain Laurel: A shrub that disguises itself as a tree, the Texas Mountain Laurel is a beautiful plant that provides lots of shade. It can grow to 15 feet high and when in bloom, it’s covered in massive purple flowers. Take note that the seeds it produces are poisonous if ingested, so those with outdoor pets or small children should watch this tree carefully.

‘Santa Rosa’ Plum Tree

  • Santa Rosa Plum – Fruit lovers, rejoice! You can still plant a variety of fruit trees in desert climates. The Santa Rosa Plum tree does particularly well in full sun as long as it’s watered regularly. Expect delicious summer fruit after an average full growth cycle of four years.

Grapefruit Tree

  • Citrus Trees – Many homeowners choose to grow a variety of citrus trees in the southwest because they do so well. Lemons, oranges, grapefruit and lime trees are especially common in yards since they naturally take to the weather.

Give It Time

Whatever tree you choose will need time to grow to its full maturity. This will be a different length of time depending on what kind of tree you decide to go with. Always talk with local gardeners to make sure you know what you’re getting into. On the other hand, you should also be prepared to make some mistakes! You’ll learn how best to care for your tree with time, so don’t feel like you have to know everything about your type of tree before you plant.

Jump Right Into It

The more you research, the more you may feel overwhelmed. This is normal for beginner gardeners, but learning how to grow your own tree really isn’t that difficult. It’s just a new way of gardening! And don’t think you’re alone. Ask around in your community to see if there are any gardening groups you can join, and if not, you can look online too. There are people ready to help guide you with your gardening passions so you can grow the trees of your dreams, no matter which kind you settle on.

Living in the desert southwest, I am blessed to be able to grow a variety of citrus trees in my garden and they do very well under most circumstances. However, when temperatures outside of the average highs and lows occur, steps need to be taken to protect them. With this week’s record-breaking highs, my orange tree has been suffering as is evident from its sunburned leaves. So I thought, this is a great opportunity to talk about how to protect citrus trees from a heatwave.

 

1. Provide temporary shade 

The west and south-facing sides of citrus trees are susceptible to sunburn during a heatwave. This shows up as yellowing or browning on the leaves on those sides of the tree. Sunburn can also occur on immature citrus fruit, so it’s important to protect them.

While spraying citrus trees with sunscreen isn’t an option, adding temporary shade is. Put a large piece of burlap over the tree, focusing on those south and west-facing exposures. Burlap is inexpensive and does allow some sun to penetrate, which is important. You can purchase burlap at your big box store, nursery, or Amazon (affiliate link below).

You can use a bed sheet in place of burlap for temporary shade. Another option would be to place a shade tent/canopy to help block the sun’s westerly rays.

Shade cloth is very useful as a sun shield when placed on a scaffold or other support – it’s important not to rest it directly on the tree as it gets hot and can burn the leaves.

 

2. Increase irrigation and water early in the morning

When temperatures soar above normal, citrus trees, like most plants, lose more water through their leaves. As a result, their regular watering schedule isn’t enough to meet their needs, so increase the frequency of watering as long as the heat wave lasts. 

When you water is vital as it is difficult for plants to uptake water in the middle of the day. This is because all of their resources are dedicated to enduring the stresses of the heat and it’s hard for them to divert those to uptake water. Water in the early morning, which will allow them to build up a water reserve that will help them through the day.

Once the heat wave is over, remove the temporary shade and resume regular watering. By implementing these two methods, you’ll enable your citrus trees to weather brutal summer temperatures and minimize any negative effects.

*Sun protection for the trunk and bark of citrus trees is essential throughout the entire year. Here is a past blog post showing you how to shield these parts of your tree and why it is so important. 

 

It’s one of my favorite times of year in the garden – my peach trees are heavily laden with delicious, sweet fruit ready for picking.

Many people are surprised to learn that you can grow peaches in Arizona, but they do very well. However, they do ripen earlier than in cooler climates. May is peach season here in the desert.

My peach trees sit outside my kitchen window, and I’ve been keeping my eye on them to see when they were ready to harvest.  Finally, the day arrived, and I brought out my bushel basket and got to picking.

One peach tree can provide you with most of the peaches you need. Last year, I made peach blueberry jam, which was so good, that it didn’t last long. Today, I’m planning on making regular peach jam, but I can always buy peaches from the store at another time to make other variations if I choose to.

Every May, I haul out my water bath canner, canning jars, and spend 2 hours making delicious peach jam.

Growing peaches and making jam isn’t difficult or expensive, but there are guidelines to follow. I made a video of the process, from what type of peach trees do best in the desert, how to tell if your peaches are ripe, and how to make jam.  I hope you enjoy!

Have you ever paused in the shade of a mesquite tree (Prosopis spp.) and noticed that its branches grow every which way? 

I was reminded of this when I was visiting a client earlier this week and was advising him on how to care for his mesquite tree. I looked up and saw a cluster of branches growing up, down, sideways, and in curvy pathways.

In an ideal situation, mesquite trees resemble the shape of more traditional tree species, as shown above. However, they don’t always turn out this way. 

Have you ever wondered why mesquite trees grow in such crazy ways?

The answer is quite simple – in nature, mesquites grow as large shrubs. The branches of shrubs grow in all directions, up, down, sideways, etc., and so do mesquites.  

The problem arises when we train them up as trees, and their branches don’t always behave as a tree’s do. Because of this, mesquites that have been pruned into trees, do best being pruned by a professional, particularly when they are young and certain branches are being chosen to remain while others are pruned off.

Of course, this doesn’t always happen, and you can see the results of bad pruning practices in many places. 

I do love the shade that mesquite trees provide and I must admit that I enjoy a good chuckle when I see the unusual shapes that some mesquite trees have taken.

How about you? Have you ever seen a mesquite tree with crazy branches?

For those of you who are familiar with ‘Desert Museum’ palo verde trees, you know how their stately beauty enhances desert landscapes. The curving branches of this tree are a lovely shade of green, which reaches toward the blue sky creating welcome shade underneath.

I have three of these palo verde trees planted around my landscape, but the one in my back garden is my favorite. Its broad canopy adds welcome relief from the summer sun, and I’m able to grow flowering perennials underneath its branches that otherwise wouldn’t survive in full sun.

Two weeks ago, this ‘Desert Museum’ tree experienced an unfortunate event. It happened around 9 p.m. on a windy day was drawing to a close. I heard a sound that sounded like firecrackers and didn’t think much of it, attributing it to kids in the neighborhood.

However, once the next day dawned, my husband called me outside to view the damage to my beloved tree. A massive section had broken off.

I must admit that I was heartsick when I saw what had happened. We had had our tree pruned by an arborist last summer and wasn’t expecting any major problems like this one. That being said, the combination of the extra weight on the branches from the flowers as well as the windy conditions of the day before was simply too much for this section of the tree.

The broken branch served to illustrate something that I frequently tell my clients; properly pruned trees are much less susceptible to branches breaking off, but they aren’t immune as my tree clearly showed. 

Under normal circumstances, I would have been upset about the loss of this major branch, but I felt a bit worse than that since we are hosting a wedding in our backyard in a few weeks and the ceremony was to take place underneath this lovely tree.

The affected branch was pruned back to a couple of smaller branches and the debris removed. Yes, my tree looks quite lopsided, however, ‘Desert Museum’ palo verde trees grow fairly quickly, and within a year, it should have filled in.

As for the wedding, plans for it take place underneath the tree haven’t changed. The small branches will grow more quickly in response to the pruning cut just above them, and I’ll probably notice the off-center appearance more than anyone else. It will still serve as a beautiful backdrop. 

There is nothing quite so refreshing as the fragrance of lemons as you slice through their yellow skin.  Lemons are a very popular fruit tree for those of us who in zones 8 and above and their lush green foliage and yellow fruit add beauty to the garden.  

If you have been thinking of adding a lemon tree to your landscape, March is the best time of year to plant new citrus in the garden as it gives them time to become established before the heat of summer arrives.

I am often asked about what type of lemon is best for the garden.  My personal choice is ‘Meyer’ lemon for a number of reasons.  You may have heard of this type of lemon tree, but what you may not know is that it isn’t a ‘true’ lemon – it’s actually a naturally occurring hybrid of a lemon and ‘Mandarin’ orange.  This results in a pseudo-lemon that is sweeter and less acidic than true lemons such as ‘Eureka’ and ‘Lisbon’.

See why you should consider planting a ‘Meyer’ lemon tree in your backyard in my latest article for Houzz.com.  (Click on the photo below to read the article).
