What do your plants look like in the middle of summer?  Do they thrive despite the hot temperatures?  


Or do they look more like this?

 
Throw in a heatwave, and your lovely, attractive plants may be suddenly struggling to survive.
 
Whether you live in the desert Southwest or more temperate climates, this can happen to you if your garden is not prepared for the heat of summer.
 
So, how do you know if your plants are handling the summer heat?  
 
Take a walk through your garden during the hottest part of the day and look for signs of wilting leaves as well as yellow or browning leaves.  All of these can indicate heat stress.
 
The good news is that you can heatproof your landscape and enjoy a garden filled with attractive plants that thrive despite the hot temperatures that summer dishes out.
 
Here are 5 tips to help you heatproof your garden:
 

#1. Use native or plants adapted to your climate.

 
 
This is perhaps the most important tip for having an attractive, low-maintenance landscape filled with beauty that thrives throughout the entire year.
 
Native (or adapted) plants have unique characteristics that help them to handle the local climate, including the heat of summer AND the cold of winter.
 
All too often, we find ourselves with landscapes filled with plants (often with large leaves) that struggle to survive the hot, summer months.  This results in unattractive plants that we work hard to help sustain them until cooler temperatures arrive.  Usually, these plants are best meant to grow in climates with less extreme heat.
 
Langman’s Sage (Leucophyllum langmaniae)
 
Let’s look at an example of an adaptation that this Langman’s sage has that enables it to handle full sun and 110+ temperatures without undue stress.
 
Notice that the flowers have small hairs.  So do the leaves, giving them a slightly grayish cast.  These tiny hairs help to reflect the sun’s rays, which lowers the temperature of the leaves and flowers.
Mexican Honeysuckle (Justicia spicigera) and Shrubby Germander ‘Azurea’ (Teucrium fruticans ‘Azurea’)
 
Another way that plants have to handle the heat is by having small leaves, which limits the amount of water lost, which helps them to deal with hot, dry temperatures.
 
Here in the desert Southwest, there are many native plants that are used as well as plants from Australia and other arid regions, which have similar climates.
 
To find out what types of plants are best adapted to your area, check your local cooperative extension office for a list of plants.  A visit to your local botanical garden can also be helpful.
 

#2. Provide shade

 
 
Adding shade to the garden can provide relief from the hot sun as well as cooling air temperatures.  The shade benefits plants and can provide cooling to the house as well.
 
*It is important to note that it can be hard to grow many plants in dense shade – especially flowering ones.  However, using trees that provide filtered shade provide just enough shade while allowing enough sun through for plants.
 

#3 Water deeply and infrequently

 
 
Plants need water to survive, and not surprisingly, they need the most in the summer.  However, we often water them too often and shallowly for it to do much good.
 
Shallow watering keeps roots close to the surface of the soil, where the soil temperatures are hot, and the water dries up quickly.
 
Deep watering is the proper method for irrigating plants because encourages deep root growth where the soil is cooler and stays moister for longer.  As a result, you do not need to water as often.
 
“Plants that are watered deeply and infrequently are better able to withstand the heat.”
 
Shrubs should be watered to a depth of 2 feet and perennials and groundcovers to 18 inches.  You can determine how deeply you are watering by inserting a piece of rebar down into the soil (right after you have finished watering) to see how long you need to irrigate.  On average, 2 hours is the length of time to irrigate to the desired depth.  
 
Almost as important as watering deeply is the time of day that you water. The best time to water is early in the morning.  Watering plants in the afternoon is not as useful since plants allocate their resources at that time toward surviving the stresses of the heat and so they do not take up water as efficiently.

#4 Mulch around your plants

 
 
Not surprisingly, mulch has a variety of benefits and not just in regards to heat proofing your garden.
 
Mulch serves to help cool soil temperatures in summer while helping to conserve moisture – all important in helping plants thrive despite hot temperatures.
 
A bonus is that they also help to prevent weeds from taking root.
 
 
Let’s take a minute to rethink our definition of what makes an excellent mulch.  
 
While shredded bark and wood chips may come to mind, did you know that fallen leaves, pine needles and even fallen flowers can also serve as a mulch?  That is how nature does it.
 
So, the next time you are tempted to whip out your leaf blower, how about directing it toward the base of your plants where the leaves and flowers can serve as a mulch?  They will also help to improve the soil around your plants as they decay.
 

#5 Ditch flowers in favor of succulents in containers

 
While growing pretty flowers in containers are relatively simple in fall, winter and spring-summer can be another matter entirely.  Often, it can be hard to grow flowering annuals in pots throughout the hot summer.
 
The reasons for this is that the soil around the roots of container plants is hotter than if grown in the ground.  This is especially true for the outer 6 inches of soil which heats up in response to air temperatures and the hot container.  As a result, annuals can wilt and struggle to produce flowers in summer.
 
Succulents are a great way to enjoy attractive container plantings throughout the year, not just in summer.  Their ability to store water is what makes them an excellent choice for containers.
 
 
If you want to grow something else besides succulents, how about trying heat-tolerant shrubs? Bougainvillea does great in pots as does lantana.
 
 
Another tip for containers is to leave them empty in the summer months and wait until fall to plant them.  
 
When thinking in terms of growing plants in containers in hot climates, bigger is better – at least 2 feet wide at the top.  The larger the pot, the more soil and therefore, more insulation for the roots from the hot outer zone.
 
 
**So what can you do if you do have plants that are struggling in the heat – particularly during a heatwave?  Other than replacing them, you can provide them with temporary shade such as a patio chair strategically placed so that it protects it against the afternoon sun.  A light spraying of water over the plant and surrounding area in the evening can help reduce the temperature – don’t do this when the sun is out, or you may burn the foliage.

“How much water do my plants need?”

I am often asked this question by desert dwellers and my answer is always, “That depends.”

desert-landscape

There are several variables that determine how much water plants need, along with the frequency of watering.

Variables include:

  • Type of soil (clay, sand, combination)
  • What kind of plant (native plants, higher water use flowering shrubs and ground covers, succulents, etc.)
  • Recommended depth of water
  • Desert region (low-desert, mid-altitude, high desert)
  • Efficiency of irrigation system
  • Water pressure (can vary between neighborhoods)
As you can see, there is no universal watering guideline in regards to how long to water or how often.

Let’s look into the variables a little more closely to help you determine what yours are:

 

SoilClay soils hold onto water longer than sandy soil. They take longer for water to permeate to the recommended depth. The result? Clay soils need irrigation less often than sandy ones but need to be watered for a longer length of time. Phoenix area soil tends to have more clay in them while those in the Palm Springs area are sandy.

Plants – Native or desert-adapted plants need less frequent irrigation versus those that come from tropical climates. Cacti and other succulents do well with infrequent irrigation.

Water Depth – Trees need to be watered deeply while ground covers and succulents do fine at a more shallow depth – shrubs fall in between the two.

Desert Region – Where you live in the desert matters when it comes to water and your plants. The differences include rainfall amounts, when the rain falls, high and low temps, and more. Residents of low-desert cities like Palm Springs and Phoenix need to add water to their plants more often than those who live in higher elevation regions such as Tucson.

Irrigation System – The older your irrigation system, the less efficient it is. This is due to mineral build-up within the system, which affects the amount of water that comes out. Also, old drip irrigation systems tend to accumulate leaks. The average lifespan for a drip irrigation system is 10-15 years. 

Despite these differences, what is a shared characteristic is that the vast majority of desert residents water too often and not deeply enough. This is usually due to lack of knowledge and thinking the ‘more is better,’ especially in the desert.
Landscapers are generally not a reliable source when it comes to scheduling irrigation – most recommend irrigating far too often.
 
So what is a desert dweller to do?
Thankfully, there is very useful information available for homeowners to help them figure out when and how much water their landscape needs.
 
Major metropolitan areas throughout the Southwest have excellent watering guidelines available for residents. The guidelines include the regional variables we have discussed so far.
Here are helpful links based on major desert cities (click the link for the city closest to you):
Watering guidelines are just that – guidelines. Circumstances may mean that you need to water more or less often, but these guides are a useful baseline to work from.
*One final note – before you implement a new irrigation schedule, it’s important to gradually wean your plants to the new one over several weeks. The reason for this is that it allows plants to become accustomed to the new schedule.

Yes, it does take a little work to figure out how much and often to water your plants, but these guides are incredibly helpful and will guide you along the way.

Do you love the beauty of bougainvillea? Many of us will agree that bougainvillea is beautiful, but many homeowners hesitate to grow them for a variety of reasons. The most common that I hear is that they get too big and as a result, too messy.
 
While both statements are certainly true, wouldn’t it be nice to enjoy the beauty of bougainvillea while minimizing its size and messiness?
 
 
Growing bougainvillea in pots limits their overall size, and with smaller shrubs, there is less mess. It also makes it easier to protect them from frost damage in winter by moving the container to a sheltered location, such as underneath a patio or covering them with a sheet.
 
 
Bougainvillea make excellent container plants. In fact, many gardeners who live in cold climates, only grow them in pots so that they can bring them indoors when frigid winter temperatures arrive. Earlier this year, I met a gardener in Austin, Texas who treats bougainvillea like an annual plant, planting a new one every year to replace the old one lost to winter cold.
 
 
Growing bougainvillea in pots is easy to do. Select a location in full sun where it will promote the most bloom. Bougainvillea is one of the few flowering plants that can handle the intense heat and reflected sun in west-facing exposures. 
 
 
Provide support for them to grow upward if desired. You can also grow bougainvillea as more of a compact shrub form if you wish, and eliminate the support.
Water deeply and allow the top 2 inches to dry out before watering again. Bougainvillea does best when the soil is allowed to dry out between watering.
 
 
Apply a slow-release fertilizer in spring, after the danger of frost is passed and reapply every three months, with the last application occurring in early September.
 
Growing bougainvillea in pots keeps them small enough to make it feasible to cover them when freezing temperatures occur.  
 
So, would you consider growing bougainvillea in pots?  I’d love to hear whether or not you would and the reasons why.

Do you like houseplants? Many people do and I’m the first to admit that I’m not an expert on growing plants indoors, so I’ve invited Lucy of Garden Ambition to share her tips for growing houseplants. I’m inspired to add a few more houseplants, and I’m sure you will too!

*****************************************************

Most indoor house plants are planted in greenhouses where conditions and the care they receive are ideal. The challenge here for you is to provide the same care and encourage them to adjust well to their new environment. New to indoor houseplants? Here’s everything you need to know:

  Indoor plants can really add character to a room.

Low-Maintenance Indoor Houseplants

If you haven’t cared for indoor houseplants before, you may want to start with the more low-maintenance ones. Not all houseplants require daily care. Believe it or not, there are indoor houseplants that can live with some neglect. These are perfect for homeowners who are always on the go and may not have all the time in the world to care for their plants. We’ve gathered five low-maintenance plants that offer a lot of benefits and more importantly, won’t die on you.

The jade or money tree has color-changing properties that provide visual appeal to any room.

  1. Jade/Money Tree

Jade belongs to the succulent family, which requires very little water. This plant bears small white and pink flowers and can turn bright red when exposed to sunlight. In the Summer, watering it once a week is enough to keep the plant healthy. Meanwhile, twice a week in the Winter is ideal.

  1. Philodendron

With a name that literally means “tree lover,” philodendron vines grow to be tree climbers in the wild. However, there are several varieties that you can choose from and take home. Philodendrons don’t need a lot of water to grow. In fact, they grow better with dryer environments in between watering schedules.

  1. ZZ Plant

A perennial from the eastern part of Asia, the ZZ plant is known for its glossy and sturdy leaves. What makes it very easy to care for is the fact that it prefers low light and dryer environments. Dry soil is recommended before you water these plants.

The aloe plant offers a ton of benefits to health and skin care among many others.

  1. Aloe

Aloe is known for its treating properties, among many other benefits. It’s a comfort to know that these plants are very low-maintenance too. Simply place it in a brightly-lit room and water bi-monthly.

  1. Snake Plant/Mother-in-Law’s Tongue

The snake plant is for homeowners who want to add a bit of height and character to any space. It has dense leaves in lovely shades of green. The trick to caring for this plant is to simply water along its edges and not in the middle. Only do this when the soil is dry.

Indoor plants come with different watering requirements that you should know about.

Growing Houseplants: Watering Tips

Indoor houseplants come with different watering requirements. Most indoor houseplants should have moist potting soil. In this matter, the distinction between moist and wet soil should be clear. Some indoor houseplants, on the other hand, prefer dry soil before watering. Such is the case of some thick-leafed plants and succulents, requiring water either once a week or twice a month. Here are some ways to gauge when your plant needs watering:

  • Check your potting soil. If the color has gone lighter or it shows a few cracks here and there, it’s time for it to drink up.
  • Pick your plant up and check if the weight is not normal. You’ll be able to master this technique after some practice.
  • Stick your finger in the soil just below the surface and determine if it’s moist or dry. This is especially ideal for large plants.

Growing Houseplants: Lighting Tips

Indoor houseplants still require some form of lighting to thrive. Light gives plants, both indoor and outdoor, the energy to produce their own food and maintain their health. Lighting for indoor plants, it’s best to keep them in well-lit rooms and windows. Artificial lighting is also available for plants that are kept in dimly lit rooms. If these lights are not sufficient for your plant, you can make use of reflectors to enhance the effect of the lighting. Insufficient lighting for indoor plants can keep the plant from growing, so you really want to stock up on valuable information about this aspect of indoor houseplant care.

Misting the leaves of the plants daily is a solution for low-humidity indoor environments.

Growing Houseplants: Humidity Tips

Most indoor houseplants enjoy high humidity. This is rather difficult to achieve indoors, especially in the Winter as heating systems are powered. Solutions to this would be using a humidifier to increase the moisture content in the air or misting the plant’s leaves daily. For indoor houseplants that require a lot more humidity than usual, keeping them in the kitchen or bathroom is ideal. Such is the case of orchids and gardenias.

Growing Houseplants: Temperature Tips

Lastly, we have temperature as a contributing factor in an indoor plant’s growth. Ideal temperatures for indoor houseplants are within the range of 64- 75 degrees during the day and 55-60 degrees at night.

Conclusion

Indoor houseplants are a great way to bring color and warmth into one’s home. Adding a piece of nature indoors can also be great for one’s health. These improve the quality of the air and can transform any indoor area into a relaxing sanctuary. But in order to reap these benefits, you must give them some appropriate TLC.

 

Hi there! I’m Lucy – founder of GardenAmbition.com and I’m a self-confessed garden fanatic. Gardening has always been a passion of mine and will always be my favorite pastime. Now that I am married and have one adorable son, I have the time to write and share my personal experiences with other garden enthusiasts like me.

*Disclosure: I was given a free copy of the book, “Beautiful, Desert Pots” in return for my honest review.

In the desert, we are fortunate to be able to grow plants in containers throughout the entire year.

 

 

Of course, living in the desert does bring along its special challenges when it comes to gardening and growing plants in pots is no exception.
 
 
However, with the right pot, location, planting mix and plants – it is possible to grow a perfectly lovely container filled with thriving plants.
 
 
I like to think of potted plants as a way to decorate your outdoor space with both color and texture.  They also offer the flexibility to change out plants easily for a different look as well as the ability to move the pots around to new locations.
 
 
A pot filled with plants is nothing short of a miniature garden in a confined space.
I hope that these photos of lovely potted gardens help to inspire you to get out there and create your own.
 
 
To help get you started, I highly recommend the book, “Getting Potted in the Desert”, written by Marylee Pangman, Tucson resident who has over 20 years of experience growing potted plants in the desert.  She is a certified Master Gardener and ran her own company, “The Contained Gardener”, where she designed and maintained container gardens for clients for years.

June is here, which marks the official beginning of hot, dry weather throughout the southwest.

While most of us can be found indoors in the comfort of air-conditioning – your plants can be suffering from the heat and intense sunlight.

May and June can be some of the most difficult months for plants in the garden until the summer rains arrive in late June.

Need some helpful tips for your June garden?

Here is my June “to-do” list that I wrote for Houzz.com.

This is a story about new beginnings – one for a new cactus and another beginning for my second-oldest daughter, Rachele.

Believe me when I say that both stories are connected in a way.

This cactus, above, is a Mexican Fence Post (Pachycereus marinatus), which has been happily growing in my front garden. 

What may not be initially obvious is that 11 years ago, I started this cactus from a 2 ft. piece of one (called a ‘cutting’) given to me by a client from their large Mexican Fence Post cactus.

Well, exactly 1 year ago, I repeated the favor for our neighbors.


Look carefully at the photo above and compare it with the first one.  Can you see where we cut off a piece of the cactus?

Our neighbors had recently re-landscaped their front yard and wanted a cactus like ours.  Of course, they knew that they would have to start out with a much smaller one – but they were unprepared for how expensive it would be to buy one at the nursery.

Our cactus had been growing so well, we decided to offer them a piece (cutting) off of our Mexican Fence Post.  So, my husband, daughter and I gathered together to take a cutting from our cactus.

Here is how we did it…


We selected a good-sized length of cactus and while I held onto it, my husband took a pruning saw and started sawing it off at the bottom.

Multiple layers of newspaper and gloves are helpful to use to grab onto cacti with short thorns. For cacti with longer thorns, you can use carpet remnants.

When you cut out a piece of cactus, it will be much heavier then you are expecting – so be prepared.


My husband and daughter wheeled the cactus cutting over to our neighbor’s house using our wheelbarrow.


We then placed the cutting in a dry, shady spot for 2 weeks in order to allow the cut site to ‘callus’ over, which would protect the cacti from rotting when it is replanted.

*Exactly 3 days after helping us with the cactus cutting, my daughter, Rachele, left for the Navy and basic training.  It was a sad goodbye for us, but a new beginning for her.

After 2 weeks had passed, the new cactus was planted in its new location with a wooden stake for support.

No water was applied for the first month after planting, in order to make sure that the entire cut end had callused over.

One month after planting, the cactus was watered deeply, monthly, until November.


*Whenever I looked at the newly-planted cactus, thoughts of my daughter and how she was doing in her new Navy life always crossed my mind.


One year later, the new cutting is doing so well and has even grown two new sections.

You can see the parent cactus in the background.

Now, I may not be located as closely to my daughter as these two cacti, but like the new cactus, she is growing and doing so well in her new career with the Navy.  We are so proud of her!

**********************
Propagating cactus via cuttings can be done with many species of cacti.

But there are some guidelines to follow for success:

1. Propagate cactus during the warm season, when the threat of frost is over.

2. Make the cut at the joint where the segment attaches to the parent plant.  For prickly pear cacti, you can cut a segment that consists of 1 – 3 pads.

3. Place the new cutting in a dry, shady spot for 2 weeks to allow the cut site to ‘callus’, which protects the cacti from rot when it is replanted.

4. Plant your new cactus in full sun with well-drained soil.

5. Don’t water for a month after planting.  Then water deeply, monthly until fall.

5. Provide temporary shade for the first summer.  You can do this by placing a plastic patio chair over the top or using shade cloth.

Soon, you will begin to see new growth on your cactus.
