July Gardens: Lantanas, Crape Myrtles, and LOTS of water!

Late summer blooms.It’s hot. The rains have pretty much stopped for the summer. Hurrican Beryl brought some rain to the eastern portions of North Texas, but most of the DFW metroplex and points west missed out on that drenching. What’s left to do in the garden? Well there’s plenty to do, including planting some of our favorite heat-loving perennials and annual color. It’s time to pay close attention to your irrigation system if you have one and, if you don’t, make sure that you are hand watering at least every other day.

This is a wonderful time to select and plant your crape myrtles. They should be in bloom at your local nursery so it’s easy to pick out your favorite colors. The same applies to lantanas and other small blooming perennial shrubs. When planting these new additions it is absolutely crucial that they are deeply watered in, and that they continue to be deeply watered on a regular basis until they begin to become established. The worst thing you can do, and we see this a lot, is to spend a ton of money on pricey specimens like crape myrtles only to plop them into a hole in the ground and expect them to survive with little water and no support! Adding annual color such as purple fountain grass, purslane, and moss rose are a great way to get that additional “pop” of color to your garden beds.

July is the time for a second application of a pre-emergent to prevent weed growth. Along those same lines it is time to add another round of fertilizer. With more frequent watering, nutrients crucial to a healthy lawn can be diluted and washed away. For our most common clay soils we recommend an all nitrogen slow release granular fertilizer. Do NOT use a “weed and feed” as they can damage trees and shrubs. If new sod is what you need, this is prime time for installing bermuda, zoysia, st. augustine, and buffalo grass. When having new sod installed make absolutely sure to water it deeply twice a day for the next 2-3 weeks so that the roots can become established. Desiree Gardens can help program a proper watering schedule for your sprinkler system after we install your new lawn.

Speaking of sprinkler and irrigation systems, it seems every year around this time we begin to have severe watering restrictions that can be devastating to both lawns and gardens. For this reason we highly recommend drip irrigation which can be retrofit and installed in almost any garden or raised bed, or installed prior to the installation of new lawns. Drip systems are usually exempt from watering restrictions because they apply water directly to the soil and are much less susceptible to waste from evaporation or runoff. Drip systems are by far the most efficient way to water your garden, and can actually lower your water bill every month. When combined with a modern ET (evapotranspiration) controller such as a Rachio, Hunter Hydrawise, or even Irrigreen, we have seen customers reporting savings on their water bill of 50% to 70% compared to older controllers equipped with just a rain sensor and standard spray heads.

Late summer blooms.July and August are the times that it is safe to trim your oak trees. Unlike most other trees and woody shrubs, oaks in North Texas should be pruned in the heat of summer. This is due to the prevalence of the oak wilt fungus, which is transmitted to open cuts by the nitidulid beetle, also known as the sap beetle. These beetles are attracted to the sap that is released from wounds on oak trees, but the fungus that these beetles transmit is much less active here in North Texas during the hot summer days of July and August. After pruning your oaks, all wounds and cuts should immediately be painted with a dedicated tree wound paint or, absent that, a latex based paint.

Another tree pest to keep an eye out for is the emerald ash borer. This invasive pest is quite deadly to ash trees and there is no known treatment or cure once a tree is infested. Recently they have been discovered in Collin, Franklin, Red River, Grayson, Hill, Hood, McLennan, and Palo Pinto counties. This deadly pest has the potential to wipe out ash trees completely in North America. Transportation of any ash wood, whether firewood or trimmings is restricted from these counties, in addition to Dallas, Tarrant, Denton, and Parker counties which are already under quarantine.

4th of July Garden Activities

Good early summer haul of tomatoes and other veggies.Independence Day is uniquely popular for outdoor activities: socializing, grilling, pool parties, and of course fireworks. Do you have fireworks going off in your garden? You should! The outdoor garden area can be one of the most popular gathering places for your friends and family. Many many summer plants are just absolutely exploding with color right now!

Crape myrtles in particular are showing off their blooms with a dizzying display of color. If you’re interested in planting one, it is the perfect time to select the exact color you want as they are all in bloom at the nursery right now. Here in North Texas almost every crape myrtle you choose will be freeze tolerant for any weather we get with few exceptions. If your crape myrtle is not blooming or even showing substantial dead branches and trunks, AND is shooting up abundant new growth from the ground it has likely suffered from freeze damage. The best action may be to cut away the dead and then cultivate new growth from the ground up. The same applies if your crape myrtles have been “topped.” Topping a crape myrtle results in ugly looking knots at the tops of the tree. There is no way to correct this, other than to cut it down to the ground (in the winter!) and then await the vigorous flush of new growth that will come out at the first hint of warmer weather.

Good early summer haul of tomatoes and other veggies.If tomatoes are your thing they should be ready for the last summer harvest now. In this intense summer heat they will likely stop producing. Most tomato varieties require temperatures at night to fall below 75° in order to set fruit, although there are exceptions. The ever popular cherry tomato can produce amazing crops of fruit throughout the summer. Other varieties include the Heatmaster tomato and the Phoenix tomato. Regardless of what you’re growing, tomatoes in the summer are water intensive. They should be deeply watered in the summer heat, but make sure the soil is well drained. As much as they like the water they don’t like roots that stay constantly wet. You can encourage them further with some shade cloth set up to block the blazing afternoon sun. Some growers even use misters to cool the air through evaporative cooling. If your dream is to cultivate hot summer tomatoes be aware that, unless you’re on well water, you’ll see a marked increase in your water bill!

Any pruning on oaks should be done this month. This is the safest time to prune oak species as the deadly oak wilt fungus is inactive. Any shade trees with low hanging branches can also be cut back. Sometimes these low hangers don’t reveal themselves in the winter dormant season when we would like to prune. They wait until they are burdened with the weight of an abundance of leaves. It won’t hurt to take down one or two of those low hanging branches right now, just don’t go overboard with the pruning. Generally speaking this is the wrong time of year to prune any trees. Now is the time these trees use all the sunlight collected by their leaves to build up reserves, and we want to avoid requiring them to divert energy to healing a wound when they should be at the peak of their growing season.

If you have hanging baskets or container gardens it’s time to add a little slow release fertilizer. Potting soil is a fantastic medium for plants, but it contains very little nutritional value. Your potted plants need those additional feedings of fertilizer that your in ground plantings get from compost and mulch. If you have flowering plants, a simple rose food fertilizer is excellent.

Good early summer haul of tomatoes and other veggies.Of course all this heat means that proper irrigation and watering is more important than ever. Don’t think that you have to water too often: it is more important to water deeply than to water frequently. Most North Texans (with a few exceptions) have a heavy clay soil that cannot absorb as much water as we would like all at once. If you’re seeing runoff onto the sidewalks, driveways, etc. then you are watering more than the soil can absorb. In these cases you will need to cycle your waterings. This means that you will water a short cycle, wait for it to be absorbed, and then water another short cycle. Lather rinse and repeat as many times as it takes for the clay soil to absorb water at least 4-6 inches down. Most modern sprinkler timers are able to be programmed in this way. If yours is older, consider upgrading the controller. Newer digital controllers are easy to program and can be controlled from your phone from anywhere. You can also add a soil moisture meter that will automatically tell your irrigation controller when the soil is too dry.
