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

Calendar, Drought, Insects and Pest Control, Irrigation, July 0

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.

What’s going on in my North Texas garden in November?

Calendar, Insects and Pest Control, Natural Gardens, November 0

Cooler weather has arrived, and the leaves are falling. Some of the best garden color of the year is here right now! Depending on what plants you have, this fall growth can last well into December. In addition to adding in pansies for winter color, other annuals like petunias will often enjoy a second bloom well into the beginning of winter.

Autumn blooms.Winter Flowering Plants
Camellias are known for their beautiful, waxy flowers that come in various colors, including white, pink, and red. They bloom from late fall through early spring, depending on the variety. Witch hazel produces unique, spidery flowers in shades of yellow, orange, or red from late winter to early spring. It’s a fragrant and attractive winter-blooming shrub. Hellebores, also known as lenten roses, bloom from late winter to early spring. They offer a range of colors, including white, pink, purple, and green. These hardy perennials are a great addition to winter gardens, and don’t forget their close relative the christmas rose. These are known for blooming right through the holidays. Finally, we have edgeworthia, also known as paperbush, features fragrant yellow flowers in late winter. The blossoms are unique and resemble small paper lanterns.

Pruning and Trimming
With the exception of oak trees, it’s just about time to look at pruning and trimming your woody plants. Prune deciduous trees and shrubs while they are dormant. This includes removing dead or damaged branches and shaping plants as needed. Don’t forget to mark low hanging branches before the leaves start dropping: The reduction in weight will cause the canopy to pop up higher and make it a little more difficult to ID low hanging limbs. Avoid heavy pruning of spring-blooming shrubs, such as wisteria, as it may reduce next year’s flowers. While we’re pruning and trimming, it’s also a good time to remove spent annuals and clear out dead or diseased plant material. This helps prevent pests and diseases from overwintering in your garden.

Leaves: Rake them?
While leaf litter can create amazing compost, it’s usually not a great idea to let it pile up on your lawn or garden beds. One option is to use a mulching mower to chop up the leaves and allow them to fall in-between the blades of grass. This keeps the nutrients in the soil while allowing your lawn to breathe, and it helps to reduce some fungi that can be detrimental to your lawn. Compost is another great option if you have room. Some people prefer their garden beds to be nice and clean, but those plants still want the nutrients. A compost bin can be an effective way to maintain a neat yard and garden while providing you with nutrient dense material. Simply add a little bit before adding mulch to your beds, and remember that a little goes a long way. On the other hand, a nice layer of leaves on a dormant bed provides excellent insulation for the roots against the cold and encourages the growth of native critters.

Autumn blooms.Planning for Spring
Your spring flowering bulbs such as crocuses, tulips, and daffodils should be in the ground now. When planting spring bulbs check the soil depth requirements for each species as some prefer to be right up near the surface while others prefer to be a little deeper. This is also the time to start work on any irrigation or hardscape projects. As our garden starts to go dormant it’s a good time to do an irrigation audit and make any needed repairs. It’s also a good time to make any hardscape changes or additions when plants are dormant in order to reduce damage to them. While you’re doing this, don’t forget to start any design or planning for spring plants. Most plants are not available year-round, and planning for your spring garden may mean talking to your gardener or nurseryman to narrow down dates when certain species are best planted.

Mid June Garden Update

Annuals, Calendar, Early June, Fruits and Vegetables, Insects and Pest Control, Mid June, Natural Gardens, Plants 1

A newly hatched Praying MantisThe summer sun has the soil warmed up nicely for all of our heat loving plants. Peppers, eggplants, cucumbers, squash, and beans should all be in the ground now. Tomatoes are likely big enough at this point that they, and other tall plants, would benefit from a cage or stake to support them. Don’t forget to prune suckers from tomato plants, and keep an eye out for hornworms that can destroy your crop.

Speaking of hornworms, it’s time to keep an eye out for other pests, and the beneficial insects that eat them. Our praying mantises have hatched, and the ladybugs are out in force patrolling for aphids. Spiders, wasps, small snakes and toads all contribute their share to pest control in your garden. While many people dislike these creepy crawlies, they are a necessary part of a healthy ecosystem in your garden. If you do find pests, you can mix a small amount of dishwashing liquid and spray them down. Diatomaceous earth powder works too, but it does not discriminate and will harm the beneficial insects as much as the pests. For snails and slugs traps work very well, and you can make your own by setting out a shallow dish or jar top filled with cheap beer.

There are also some pests where you’ll have to make a judgement call: Swallowtail caterpillars absolutely love dill and fennel, and can denude a plant in just a few days, but if you kill the caterpillars you won’t have the beautiful butterflies they turn into. Gulf Frilly caterpillars love Passion Flower vines and their voracious appetites can reduce the number of amazing blooms you get, but again: No caterpillars, no butterflies. In our experience, simply having healthy plants is usually enough that the caterpillars can get their fill and the plant can survive just fine.

The weather lately here in North Texas has brought us an abundance of rain, but anyone who has lived in Texas very long knows that this rarely lasts. As the rains taper off and the heat continues, it will be more and more important to water appropriately. Deep soaking watering is vastly preferable to more frequent shallow watering as it will encourage the growth of strong deep roots. If you are hand watering or using a sprinkler you should water very early morning to minimize evaporation. In the same manner, drip irrigation is even better as it applies water to the soil directly where it is needed. You can cover your drip lines with mulch to further eliminate evaporation of the water.

Speaking of mulch, you can’t really go wrong applying another layer of mulch around your plants. Not only does this help to conserve soil moisture as alluded to above, but it will also suppress weed growth and help stabilize soil temperature. We use organic materials like straw, wood chips, and even shredded leaves as mulch, and place it over a layer of cardboard or newspaper (junk mail works too, just not the glossy stuff.) If you get mulch from a garden center or nursery, you should avoid dyed mulch. Red and black dyed mulch is the most common, but the chemicals in the dyes can have negative effects on your plants. A good 100% hardwood or cypress mulch is what we recommend, and it looks just as good as a fancy dyed mulch.

It’s also time to start harvesting some of your plants! Blackberries, plums, green onions, and asparagus are already starting to ripen. If you grow asparagus, this should be your last harvest of the year and the plant should be allowed to rejuvenate as an ornamental until the next harvest.

June is also the time to plant annual flowers that thrive in the warm weather. Consider colorful options such as cocks comb, marigolds, zinnias, cosmos, petunias, and sunflowers. Most of these plants appreciate full sun. Prepare your annual beds with a good mix of compost, landscapers mix, and top off with mulch.

Remember, specific gardening tasks can vary depending on the microclimate and individual garden conditions within North Texas, and readers to the north or south of Zone 8 will have slightly different timing.

Garden Insects

Insects and Pest Control 0

One of the more frustrating things for any gardener is when they venture outside to the garden only to find voracious insects devouring the product of their hard work! What can you do about these tiny critters without resorting to poisons or insecticides and other harmful chemicals?

First, identify whether the insects are truly harmful or not. Some caterpillars for example will strip a fennel or passion vine bare within just a few days. Most of these caterpillars have very specific tastes however and will soon transform into beautiful butterflies. Pollinators like butterflies are critical to the success of any garden. Sometimes it’s better to take a little hit and have fennel, or passion vine that looks denuded for a bit just to gain the benefits that these beautiful winged creatures provide. Another alternative is to plant, or allow to grow, other plants like milkweed. In a natural meadow-like lawn, “weeds” like milkweed provide a tastier source of nutrition to many caterpillars.

This Asian Beetle is NOT a Lady Bug
This Asian Lady Beetle (Harmonia axyridis) is NOT a Lady Bug! They look alike, and both are effecient predators of aphids, but the Asian Beetle is an invasive species with a mostly white head and more spots, while the Lady Bug has a mostly black head and fewer spots.
If you’re inspecting your plants and find ladybugs, or their immature larva which appear like tiny black and orange alligators, stop! Those are the good guys, but their presence often indicates the presence of aphids. Aphids are the main source of prey of the ladybug. If you find aphids sucking down your plants, and you don’t see ladybugs, you can often purchase some at your local plant nursery.

The praying mantis is another beneficial insect, which preys upon many common pests. Finding one is a boon! If your garden seems overrun with harmful insects, you can purchase more praying mantis from your local plant nursery. These insects, along with other beneficial critters like spiders, tarantulas, and tiny garden snakes, all help wage war on your behalf against the tiny pests that might otherwise plague your garden.

Some pests like hornworms, which love tomatoes, are more difficult to remove. These you might need to pluck off one by one. An alternative is a dilute solution of gentle dish soap and water sprayed onto the plant, including the underside of the leaves.

If you have fowl such as chickens or ducks, allow them to roam the garden from time to time. Both chickens and ducks have quite the appetite and love dining on all manner of pests, including slugs and snails. Of course, slug and snail traps such as a saucer full of beer also work well for these molluscs.

Whatever plagues your garden, always search for the natural solution before resorting to pesticides. Many of these chemicals and compounds are indiscriminate and will harm beneficial insects along with the pests. What’s more, they can cause irreparable harm to pollinators such as bees and butterflies.
