Water is a priority issue in this severe drought. You may wonder: Can we set up an oasis garden in our yard while restricting water usage?

You have choices. By using pots, you will use water more sparingly, as you are watering a very specific area. By being mindful about how much water you supply to your pots, you will average a gallon or two per day for each 20-to-24-inch pot with high water plants, such as flowers, planted in full sun. Medium-water thirsty plants will only need water every other day; low water plants need water every third day, perhaps even less often. Therefore, if you have 10 pots, the most water you use is 20 gallons a day—and that’s if all are planted with water-greedy plants in the full sun.

The average resident in the United States showers for eight minutes, using 17 gallons of water. If you consider some logic here, cutting your shower time in half will let you add four pots to your yard—and not use any more water!

As you would expect, the key to success in your hot desert pots is water. However, 95 percent of plant failures in the desert are caused by inappropriate watering. This includes TOO MUCH WATER! Don’t assume, as a newcomer to the desert that you have to water all of your pots all the time.

Where to Be Cautious With Water Use

Houseplants tend to be loved to death with water. In colder climates, even in the winter, you need to water indoor plants only weekly, and that’s due to dry heating systems. Most “houseplants” can be watered every three to four weeks.

Shaded patio plants also tend to be overwatered. Use a water meter to test how wet the soil is down in the root zone. Most homeowners use their finger to test the top inch, which may very well be dry. But the roots are 6-10 inches below the surface, and that area does not dry out as fast. The amount of wind the plants get will also dictate how fast the soil dries out. If the soil is damp, but the plant is struggling, try blasting the plant itself with water weekly, and misting the leaves now and then.

Potted succulents and cactuses during the hottest seasons may need water weekly; during the more pleasant months of the year, it’s every two weeks. I suggest you see how the plants do if you water even less often; after all, they are desert plants. Watch for wrinkling of the pads or stems to know if you need to increase water.

If you do have your potted plants on irrigation, watch out for plugged pots or errant emitters, as you may find your pot filled with water. If so, with a friend’s help, lean the pot over until you can stick a screwdriver up the drainage hole to relieve the block. The next time you are repotting, empty all of the soil out of that pot, and resolve the problem. It could be root growth from the plant, or a nearby ground plant with its roots growing up into the pot.

All pots do not have to be planted with high-water selections. Consider using plants from the Southwest, along with non-native but desert-friendly plants from the Mediterranean and Africa.

Blooming flowers from many of these plants will attract bees, butterflies and hummingbirds, and grow together, creating lush landscapes that contradict stereotypes about the desert. Intermingle the occasional flowering annuals like those from “back home,” and regulate the water applied for each type of plants’ needs.

It is important to place plants with like needs together—both in respect to sun and water. Combining shade and sun plants in the same pot, and/or high- and low-water plants, will only result in disaster, perhaps leading you to become one of those newcomers who throws up your hands and says, “You cannot grow anything but cactus in the desert!” Not true—just look at the desert potted garden below.

If you water your pots with an irrigation system, set it to come on about 4 a.m., and water before the lines heat up in the sun. If you are watering by hand, water as close to sunrise as possible. Be sure the water coming out of the hose is not hot, and water pots until the water comes out of the drain hole.

However, only water your potted succulents and cacti when the soil is almost dry. Again, use a water meter to determine this.

Interested in being rewarded for reducing your grassy areas? The Desert Water Agency (DWA) has just relaunched its turf buy back program to encourage residents in the western valley to reduce the amount of living turf they have at homes and businesses.

The high season, the off season, the “shoulder season”—there are many ways we talk about the seasons in the desert. With the sun shining 354 days a year on average, it can be a gardener’s delight.

The shoulder season for the hospitality industry is late April through the end of May, and then again in late September and October. Temperatures can still get high (80s and above) in these months, but the nights start to cool down to the mid-50s and 60s. (See the chart below.)

Our desert potted gardens are the most frustrating to deal with during the shoulder season, as noted in the chart above in green. As I’ve discussed all month, we may want to plant for the next season, but the flowers are not ready.

This is, however, a great time to plant some vegetables and herbs, as they do well in containers. Make sure your containers are large enough, i.e. with an interior diameter of at least 20 inches.

The more soil you have, the cooler you will keep the roots.

I suggest you buy 4-inch pots of plants at a nursery rather than a big-box store, and use plants, not seeds; it will be easier to get them going. Water in the morning, before 7 a.m., so the plants have water for the day. You can still plant sweet basil as well as parsley, chives, oregano, sage, rosemary and thyme. You can also get a jump start on young tomato plants—as long as you keep them in afternoon shade.

This month, I have been talking about the upcoming “shoulder season” between summer and winter. This time period in other parts of the country is considered fall. Depending on our temperatures each year, we may or not have a fall.

This is the time of year when our summer flowers are failing, but it’s too warm to grow winter flowers yet. As I’ve discussed previously, my go-to list of shoulder-season annuals includes:

  • Alyssum
  • Dianthus
  • Dusty miller (complementary plant)
  • Geraniums (best in morning sun only; no sun in summer)
  • Marigolds
  • Osteospermum
  • Petunias
  • Snapdragons

When you get to the nursery in September or early October, there are a few other plants you might come across that will serve your decorative needs just fine until the temperatures mercifully drop below 70 degrees at night.

The first is the Mexican blanket, or gaillardia, as pictured above. Actually a perennial, this plant may survive all year long with a good pruning when it takes a break from blooming. The bright orange/red flower attracts butterflies and is a good cut flower to bring inside your home.

Another plant to add to this list is the ever-popular chrysanthemum. Another perennial, these plants can often be found in the early fall in nurseries. In kinder climates, “Mums” can be kept in pots or in the ground year-round but will only flower in the fall. If you are looking for a great plant with many color choices to spruce up your home before Thanksgiving, Chrysanthemums are a sure bet. However, unless you are a diehard “saver” of your plants, I would send it to the compost heap when it is done flowering. Being of the immediate (and continual) gratification generation, I don’t want to look at a green plant nine to 10 months of the year. I’d rather use that space in my pots for bloomers.

As we approach “fall” here in the desert, the picture above may look familiar. I don’t need to tell you how challenging our summer is for any garden (except for perhaps gardens solely consisting of desert cactus). But true gardeners keeping trying—right?

Of course, we should not be planting our winter pots in our Palm Springs gardens until late October. I can just hear you replying, “Oh my! I cannot wait until then!”

Don’t give up yet, though. Remember, I am the person who continually says I expect to have color 365 days a year in my potted gardens!

Here are a few tips on how to approach your pots if they look like those above:

1. See if you can find new growth (healthy green sprouts) coming from the center of the plant. If you do, prune the plants back to that new growth. However, you must provide shade for this tender new growth. Either move the pots into the shade, under a dense tree or into a spot with only very early morning sun. You can also use a 70-plus-percent shade cloth. With this protection, the sun will not burn the new growth coming from the plants.

2. If you don’t see new growth, discard the baked plants. They will not rejuvenate, and it’s better to replace them with some new plants.

3. Go to the nursery early in the morning. If they don’t grow their own annuals, try to go on the day the nursery gets in fresh plants. Buy quart- or gallon-sized plants in order to have the greatest root ball and root mass, which will protect and support the plants in our continuing heat. Refer to last week’s column.

4. When planting new plants, add some fresh time-release fertilizer to the soil. If you have existing plants in the pot, don’t put in as much as recommended on the package: You do not want to burn the roots. Make sure your soil is damp before fertilizing and planting. Add half-strength fertilizer, and tuck in your new plants where you have bare spaces. (See the photo to the right.)

With a little care, shade, water and patience, a well-planted September pot, such as the one shown below, will serve you into your low desert winter.

Snowbirds will soon begin to return to the Coachella Valley. Once they arrive, they’ll be quickly reminded of their pre-summer departure, as they find empty pots around their home.

One of the first items on the agenda after unpacking: Planning new gardens!

We’ll soon enter one of those periods of time between winter and summer known in most regions as “fall.” The comfortable temperature months of September and April can try our patience as we seek out flowers to plant in our now-tired pots. Often, our selection is somewhat limited, considering it may not truly be time to plant yet.

These are what I call the “shoulder seasons” of desert gardening. We should hold off on planting some things until nighttime temperatures reach levels that are just a bit cooler. Growers cannot push out plants that will succumb to the heat too early: We need night temps to get out of the 60s to plant true winter flowers. Yes, it is the nighttime temperature that dictates our planting cycles: As long as the plants can be warm or cool enough at night (depending on the season), they can handle the days’ swings between 70 and 90.

Even though some nurseries may have winter flowers on offer such as pansies, violas and ornamental kale, if we plant them too soon, they will struggle to survive, often succumbing to the constant heat in September and early October. Pansies get leggy and weak. Kale bolts early.

However, if we are patient and use flowers that can withstand the challenges of our long summer, we will be rewarded with stunning potted gardens.

To help desert residents enjoy potted color 365 days a year, I have created a short list of flowers and complementary plants that will thrive during the shoulder season—and often make it through much of the following season, too. Many of these flowers are becoming increasingly available during all seasons. Under the right conditions, they might hang on longer and longer. The “right” conditions typically mean receiving afternoon shade or filtered sun during the eight to nine warmer months. They will certainly stand up to the low desert’s cooler temperatures in the winter:

  • Alyssum
  • Bacopa (shade perennial)
  • Dianthus
  • Dusty miller (complementary plant)
  • Geraniums (best in morning sun only; no sun in the summer)
  • Marigolds
  • Osteospermum
  • Petunias
  • Snapdragons

You can see some attractive combinations in the accompanying pictures. Using the taller varieties such as osteos and snapdragons as center or backbone plants will give you some great height to start your arrangement. Dianthus also comes in some newer hybrids, including “Amazon,” where heights far exceed the standard 8-to-10 inches of older varieties.

Next in your pot should be mid-height plants such as the dusty miller, marigolds and petunias. As you know, petunias will also trail, so don’t put anything between them and the pot’s edge.

Lastly, alyssum and bacopa are your true trailers. Bacopa will not tolerate the strong desert sun, so keep it in the shade or on the shady side of the pot.

California residents are dealing with unprecedented water restrictions due to our record-breaking drought.

Those of us who garden have a choice: Either we can simply comply with these limitations, or we can morally commit to reacting in a way that will help our state achieve sustainability. I, for one, believe we must take control of our water usage.

Water restrictions vary from agency to agency. Palm Springs’ Desert Water Agency, for example, restricts landscape irrigation to Monday, Wednesday and Friday during overnight hours. Fortunately, most desert landscape gardens do not need three days of water. (Please don’t get me started on grass in the desert. Artificial turf is beautiful, and lawns do not belong here.)

Of course, container gardens offer flexibility regarding placement and size—and, therefore, water usage. Here are some tips to embrace sooner rather than later. (Although I am writing about pots, many of these tips can translate to raised beds, landscapes and bedding plants.)

1. Take a pail into your shower, and fill it with the water that comes out before the water reaches your desired temperature. Use the bucket to water thirsty plants.

2. When rain is in the forecast (rare, but it happens … hopefully), put out buckets and barrels to gather as much water as possible. Rainwater has many beneficial micronutrients that your plants will appreciate.

3. If you are gone a lot, don't plant water-hungry plants and flowers. After all, you won’t be around to enjoy them.

4. Plant fewer flowers and more succulents—and consider leaving some pots empty.

5. Use large pots (greater than 20 inches wide and deep). Once new plantings are established, they will need to be watered less. You can add more water to thirstier pots from rainwater and your shower.

6. Make sure none of your irrigation emitters are over-spraying into areas with no plants.

7. Check for dripping hose bibs and leaks in your irrigation.

8. Shorten your irrigation run times. If you can cut the time by 25 percent, you will be doing more than your part. If you have your pots on a dedicated line with adjustable emitters, they should only run for five to 10 minutes—and cutting the time by 25 percent will bring those times down to four to seven minutes. As long as the plants are established, that’ll probably be enough water. If it isn’t, you always have that shower water!

9. Never irrigate your cactus and succulents. Even in the Coachella Valley, they really only need water once a week—and that is only if they are in full sun. Succulents in the shade will probably get by with watering every other week.

I am a huge proponent of setting up a dedicated irrigation line to your containers. The watering-schedule settings are very specific and not as subject to human error or forgetfulness. Irrigation lines also save water over hand-watering. I suggest you use an adjustable emitter. Be absolutely certain that you have a dedicated line for pots, because if you add pots to the landscape line, you will be over-watering your potted plants—and wasting hundreds of gallons of water.

Water is a necessity for every living thing. Save some of this precious resource while continuing to enjoy your garden.

We all need respite from the heat—and I recently received one, thanks to my high school and college reunions.

Luckily for me, they happened on the same weekend, and I wound up splitting my time between two different towns in upstate New York. I visited some tourist spots—and checked out some flowering pots that we just happened to find. I found many of the same flowers that we grow in our desert gardens—although we tend to grow these plants in the winter and surrounding seasons rather than in the summer.

The upstate New York window box shown below is filled with petunias, bacopa plants, marigolds and, in the center back, some flax. This arrangement would do very well in the fall and early spring here in our low desert climate—but most of the plants would succumb to the summer heat. (You might be able to keep the bacopa going in the shade, with ample water.)

On a previous visit to New York state, I went to Niagara Falls for the first time in probably 40 years! It was in July, and the flower beds were filled with similar plants. What a different world I used to live in. However, I don’t miss the snow!

Volunteer plants! We often get surprised by something we did not plant that shoots up. These plants can come from previous plantings, seeds carried in by the wind, and even bird droppings.

One of the nicest surprises is when alyssum plants (above) pop up during late summer rains. We might find volunteer vinca, and some volunteer cactus in a hidden shady spot. (Feel free to move the cactus after the summer heat has dissipated. It may not be growing where you will want it to mature.) Think of the potential reward when we grow any cactus that surprises us with spring or fall blooms!

Below, you can see some summer flowers that decided to sprout up at my desert home. They came up in areas where there obviously was some water runoff from irrigation.

Enjoy!

Desert homeowners often complain about birds eating their potted plants and flowers. Unfortunately, I have not come up with any way of truly deterring them. Some people try bird nets, pepper spray and spinning reflective objects such as CDs, pinwheels, etc. However, birds seem pretty smart and focused when there is something they want.

The biggest surprise is going out to a pot—and finding nest full of eggs. Often, you will discover your pot has become a quail’s nest. The lucky homeowner often will ask: What should I do?!

The best idea is to keep the pot (if living plants are sharing the pot with the mother quail) slightly moist. When you water, it will scare the mama bird away, but she will come back. Quail and most other birds are very devoted to their offspring. With patience, you will be rewarded with a covey of quails following Mom and Dad until they start to fly.

Hummingbirds will build their nests in high spots, usually under some shade. These golf-ball-size nests are hard to find, but I once had one in a driftwood wind chime that I hung outside my window. The best thing to do for the hummers is give them privacy.

My least-favorite nesting bird is the dove. They seem to think that two sticks will make a nest—so you will find them making messes on ramada rafters, window ledges and outdoor speakers. I try to discourage them from coming by placing wire or chicken-coop fencing in an area in which they may have interest. However, it may be best to simply enjoy all of our feathered friends and let them raise their families.

Shade is a good thing during our hot summers—and some ground-cover plants offer a lot of great shade for our summer pots!

The entire vinca family (perennial groundcover vincas) will grow easily, even in our summer heat, as long as the plants are in the shade. Above, you have a picture of the beautiful gold and green variegated vinca, “Golden Illuminations.” You will have no problem keeping the plant going down the sides of the pot.

You can also find vinca major and vinca minor, with deep, glossy green leaves; one of the few differences in the two varieties is leaf size: Major leaves are about twice the size of minor leaves. Each variety also comes in a variegated style. (The variegated vinca major is pictured to the right.)

Another key difference between major and minor is the growth height. Vinca major will grow to 10 inches tall, even in pots, so it is a little more challenging to keep the plants cascading. Minors will have no problem trailing down the pot.

Keep these plants evenly moist, in shade areas (one hour of early morning sun is OK in the summer; more in the winter is fine).

In previous columns, I’ve discussed the Purple Heart Plant, or "Purple Wandering Jew" (Tradescantia pallida), seen in the first pic below. Too many desert-dwellers try to push this plant in sunny landscapes; however, it thrives in shady conditions, or filtered sun in the winter. As you see in the picture, it does grow to about 10 inches in height but will also cascade as the branches get longer. It is somewhat drought-tolerant—but you’ll still need to water it, and make sure the soil does not completely dry out.

One landscape groundcover plant that will hold up to the heat of the day all year long is the trailing rosemary, shown in the second photo below. Be sure to select a plant that is “trailing” and not the upright rosemary: The latter will grow up to 4 feet tall, while the trailing rosemary tops out at 6 inches. Plants left in pots more than two years do get somewhat woody, but they respond well to pruning. Don’t forget to use new growth in your cooking!
