Should you plant a palm tree oasis in your back yard?  Maybe…or maybe not

For centuries palm trees have been symbols of comfort and safety whether spied in an oasis from afar in a scorching hot desert or…standing tall as a “land-ho” sign after crossing a vast stretch of ocean or…simply marking the beginning of warm weather country when traveling south in the U.S.

As symbols or signs, palm trees are great. I love seeing them lined up along The Strip in Las Vegas, and Arroyo Parkway in Pasadena and Canon Drive in Beverly Hills. But as for planting a palm tree in a residential garden…I am less enthusiastic.

3 Washingtonia robusta fan palms
Three Mexican fan palms.

Plant a Mexican fan palm (Washingtonia robusta) or a fruitful date palm (Phoenix dactylifera) and within a few years you have a tall, round brown column in your front yard. The graceful green fronds will have grown out of sight and cast very little shade.

The Mexican Fan palm has vicious thorns on its fronds and a prick from one thorn can cause an infection. And if your sky-high date palm produces fruit, the dates will drop and make a mess—albeit a tasty mess—in your yard.

But there are two and a half smaller palm trees that are more suitable for home gardens in hot, dry climates.

Pindo palm California fan palm

The Pindo palm (Butia capitate) has long fronds, like the date palm, but grows very slowly to 20 feet tall and about the same width.  It produces a yellow fruit that in some countries is turned into jelly or wine. It is the smaller palm in front in the photo. Behind it is a Mexican fan palm which is growing its way to 60 feet tall. Both planted at the same time.

Mediterranean fan palm Chamaerops humilis

The Mediterranean Fan palm, (Chamaerops humilis) as the name states, has fan-like fronds similar to the Mexican fan palm, but it is essentially a palm shrub, not a palm tree.  Many people trim the lower fronds off the multiple trunks to give this plant a more traditional “palm tree” shape. A slow grower may reach 15 to 20 feet someday. Its small, brown fruit is not edible.

Both these smaller palm trees can survive chilly weather, even a quick light dusting of snow!

sago palm cycad

And now for the “half palm tree”.  It is commonly called a sago palm, but it is not a palm at all. This low growing cycad is closely related to evergreen pine trees. It can be an attractive addition to a palm garden oasis and grows really s-l-o-o-o-w-l-y. Be sure to plant in a backyard; thieves steal them from front yards regularly because they are very expensive plants. Another note about the sago palm: its bright red fruit can be toxic to dogs and other small animals and is not good for humans of any size.

So even though palms like being planted in warm soil and can be planted in warm weather if watered sufficiently, consider how it will look in a few years. In my opinion, it is better to invest your money and time planting a fast growing Chitalpa tree (Chitalpa x tashkentensis).

Take the “screwdriver test”. Your lawn will thank you.

Replacing a traditional front lawn with other drought tolerant grasses makes good sense.

Officially, the drought is over in California.  At least Gov. Jerry Brown said so.  But in Southern California and Nevada and Arizona and parts of Texas–even in New South Wales in Australia–drought conditions continue.

So many responsible homeowners are replacing their front lawns which we all now realize are nothing more than giant green sponges.  Keeping a lawn behind the house, however, can make a lot of sense, particularly as a play area for children.

And that backyard lawn needs regular watering.  But if you are not sure if you are watering your lawn too much or too little, here is an easy test:

Take an 8 inch screwdriver and push it into various places in your lawn about an hour and a half after you have watered.  If the screwdriver goes in easily, you are watering enough. You may even want to consider cutting back a bit on water.  If you cannot push the screwdriver all the way in, you need to increase the amount of water for the lawn.

Simple, right?

If you still love the look of a grass lawn, consider planting Buffalo Grass, a native grass of the American Plains. It has been hybridized in recent years so it now looks like a traditional lawn, rather than fodder for roaming buffalo herds.  It greens up in warm summer months, then goes dormant and brown in the winter. If you decide to go this route, be sure you plant plugs — not seeds. A Buffalo Grass lawn needs little or no watering at all.  Not much mowing either. (Note: this is not Buffelgrass, an invasive African grass that now threatens saguaros in Arizona.)

How to prevent death by dehydration with your potted plants

4 pots on patio
Tucked behind a pillar under a patio cover, these plants continued to survive in scorching summer heat.

I’m going to wear my “Captain Obvious” hat for this post–at least for the first 3 items.

First of all, keep those pots  containing plants in the shade. For example, under your patio cover, a big shade tree or on the north side of your home. Even then you may have to water the pot/plant more than once a day in a desert-like garden. It takes almost no time at all for hot and dry direct sunshine to suck all the water out of a plant. And if it windy, the dehydration happens even faster. At that point, the plant wilts and  it is highly unlikely that even generously watering the plant will bring it back.  It is doomed to death by dehydration.

Second: do not plant in metal containers.  Many gardening magazines tout shiny metal pails as suitable for plants. But the metal container heats up fast–even if it is not in direct sunlight–and “cooks” the roots of the plant. It is guaranteed to be another plant death by dehydration.

And third: avoid those shallow bowls that you find filled with plants at gardening centers as instant-gardens-in-a-clay-pot.  Only smallish succulents will survive for any length of time in them. There simply is not enough soil for roots to grow vigorously and absorb sufficient water to survive.

Now for a couple of positive suggestions, including a controversial one

Consider double-potting your plants. Place a larger pot around an inner one and fill in the space between with wood mulch or dried moss. Yes, I know it can be expensive to buy two different size pots for one plant, but it is effective. The wood mulch or moss acts as insulation. If you pour a little water into the space between the pots to dampen the mulch it increases the cooling effect. Do not add too much water, however, as it may end up flooding the inner pot from the bottom up, thus drowning the plant!

Now on to polymers, those water-retaining gel crystals, that are usually used in flower pots to help both cut down on watering and retaining water in the soil for the plants’ use. No question that polymers are effective. Recently, however, we heard a gardener advocate using water-retaining polymers in flower beds and in the soil around trees in a desert garden. It sounded like a good idea.

But a little online research revealed a preliminary study which indicates that polymers may break down in our native soil into chemical components that may not be good for plants and people. So while polymers may be helpful for plants in pots, do not start spreading them around your garden.

Making sure you have a lot of organic material in the pot is a better way to go. Soil rich with organic material absorbs water well and supplies nutrients to plants.

Best fruit to plant in a hot, dry desert-like garden

pomegranate fruit on bush (

Shortly after moving to Las Vegas back in the 1990s I went on a hike with the Sierra Club in what is now the Red Rock Canyon National Conservation Area. Our destination on this hike was an old abandoned ranch about 3+ miles from the pull-out on Highway 159 where we parked our cars. The ranch owners had walked away from the ranch years ago and turned it over to the Bureau of Land Management. (And the BLM had pretty much just ignored the place.)

So about 10 of us tromped off across the wide canyon floor. As a newcomer to desert hiking I forgot to bring water and it turned out there was no water at this old ranch. Just a weather-beaten house, a couple of fences that tilted and sagged…AND a row of pomegranate bushes still producing big red pomegranate fruit. These 8-10 foot high shrubs had survived for years with only the water that fell from the sky. And in Las Vegas, the average annual rainfall is about 4 inches! It might be a bit higher up in Red Rock Canyon, but not by much.

This was evidence that pomegranates grow well even under very dry conditions. And if you add a little bit of care and water they will do even better. Another plus: the leaves turn a lovely yellow in Fall and at Christmas time the fruit–if you haven’t picked it–looks like red ornaments in your garden.

So if you want a low-water usage fruit to harvest from your own backyard, plant a pomegranate. The ‘Wonderful” variety is an excellent choice and will do well even with neglect.

But don’t neglect taking water with you on a desert hike. I have always had water with me ever since that day.

Hello hot gardeners!

Aloe blooms in February
These South African aloes are among the early bloomers in a desert garden: their colorful spires rise above a fairly mundane looking plant in February.

Let me start by introducing myself.  My name is Carol Lightwood and I am a Master Gardener who earned my official state certification in Clark County, Nevada.  More specifically, in Las Vegas.

Shortly after completing the lengthy Master Gardener certification program in 2003 I launched the Hot Gardens website to help newcomers to the Las Vegas Valley understand the challenges of gardening in a desert climate. (ProTip: don’t plant pansies!)

Gardening conditions in the Las Vegas Valley and elsewhere in the U.S. Southwest states are horrible! Poor soils and, in Vegas, only 4 inches of rainfall annually. Since I loved having a beautiful garden, I began by planting Mediterranean plants that I knew  were drought tolerant from my years of living in Southern California. With considerable soil improvement, some care and water, most of them thrived in my enclosed patio garden. And I continued experiments with plants that could create the illusion of a lush garden with very little water.

For years I wrote a monthly newsletter about techniques and tips for best gardening results in a hot, dry garden. And hot, dry climates are expanding these days as the earth experiences climate change.The readership for the Hot Gardens site now includes gardeners from Australia, India, South Africa and the countries on the Arabian Peninsula as well as Spain, Canada and the U.K. So I decided to start giving gardening advice again and will be posting to this blog every so often.
