Summer is here and we need to be on high alert for 3 of our most common summer pests:  spider mites, mealy bugs, and lace bugs! Here’s where to look, how to identify, and how to treat effectively with 1 simple solution. 

Spider Mites!

Look out for these little white specks and fine webbing…hence the name spider mites! They like plumeria, junipers, all kinds of houseplants, and they’re common in the veggie garden. The mites themselves are usually on the underside of leaves. Use organic Spinosad Soap to spray the affected plants all over, making sure to get underneath the leaves. 

Mealy Bugs!

Mealy bugs especially love Hibiscus, Jatropha and some Salvias. Look on the tips, stems, and undersides of the leaves for these white insects clustered together. If they go unnoticed for a short period of time, they will produce a protective cottony barrier over their bodies to protect themselves. Many times we hear “I have a white fungus on my plants”, but it’s usually mealybugs. Once again, organic Spinosad Soap is effective for killing these pests. Multiple applications may be needed. Thorough coverage is a must, and we recommend spraying once a week for 2-3 weeks to make sure you have killed them all. If you only have a few clusters of them at the tips of your plants you could smash them with your fingers and rinse, or cut off the affected tips and throw away the bugs in a sealed bag.

Lace Bugs!

Are your lantana looking rusty brown like a fungus has attacked them? Well it’s not a fungus it’s lace bugs. Lace bugs are common this time of year, and they attack lantanas leaving them looking ugly and half dead. This problem is easily fixed by pruning back the ugly plant either one third to half way depending on the damage. Rake up the bad leaves which will eliminate the majority of the bugs, fertilize with your favorite plant food and water in, then spray with Spinosad Soap. The plant will quickly recover like nothing ever happened, putting on a flush of new growth and blooms.

Your Best Solution + Other Considerations

As we keep repeating, our first recommendation for all 3 of these bad bugs is Spinosad Soap. It’s easy to use, all natural, and very effective. If you have a really bad infestation, you can use Cyonara, which contains the chemical lambda-cyhalothrin. Keep in mind, while oil sprays (Neem oil or horticultural oil spray) are effective for controlling these insects, you do not want to use them in the summer time or you risk burning your plants! 

 

Mealybugs are here! Look on the tips, stems, and undersides of the leaves for these white insects clustered together. If they go unnoticed for a short period of time , they will produce a protective cottony barrier over their bodies to protect themselves. Many times we hear “I have a white fungus on my plants.” Safer’s Insecticidal Soap and Natural Guard Neem Oil can be used to kill these pests. Multiple applications may be needed. Thorough coverage is a must, and I usually recommend spraying once a week for 2-3 weeks to make sure you have killed them all. If you only have a few clusters of them at the tips of your plants you could smash them with your fingers and rinse, or cut off the affected tips and throw away the bugs in a sealed bag. Be a bug scout. Keep your eyes open and search. These pests usually last most of the summer.

No Need To Wait… Plant Hardy Trees And Shrubs Now!
The roots of hardy plants grow during our cool months even though their leaves may be changing color or falling from their branches. This provides a better root system so they thrive in spring and can survive the long, hot summer. Live oaks, magnolia, cedar elm, hawthorns, holly, sage, junipers, roses, just to name a few, are winter hardy and would be appropriate to plant now. Perennials like lantana, turks cap, and ornamental grasses also benefit from planting during the winter months.
Are Your Tropicals Looking Winter Worn?

Hot weather tropicals such as hibiscus, bougainvilleas, esperanza, plumbago and many more suffer from the sudden temperature drops in the winter. Even though we have not had a freeze, the last really good cold snap made our plants look pretty bad. The leaves turn yellow and brown and most plants also suffer lots of leaf drop. This is normal so don’t be alarmed. In late February to early March you should cut all these plants back one third to half their size and fertilize. They will flush out with new spring growth and you will never know they looked so bad over the winter. The beauty of spring!!

Our Thoughts On Winter Watering

Since the temperatures are no longer in the 90’s and plants are not actively growing they require less water. This includes the lawn. Change your watering schedule on the lawn and established shrubs to every 2 weeks slow and deep instead of once a week. Potted plants no longer need to be watered everyday. Most could go every 2-3 days. Night-time dampness and fog helps to keep moisture in the soil. By changing your watering habits you help to reduce fungal problems which are prevalent with these conditions.

Time to fertilize your lawn, trees & shrubs! Hopefully by the time you get this, the sunshine will have warmed and dried the soil enough to fertilize. Use Gill Lawn and Garden for all your trees, shrubs, vines and groundcovers. Also feeds the vegetable garden. Covers 6000 sq. ft. per bag.

For weed control in your lawn, use Weed B Gon for St. Augustine. We have a new formulation that is safe to use on Floratam St. Augustine Grass. Treats up to 2500 sq. ft. and comes in a ready to spray hose-end bottle. Image will kill some broadleaf weeds (dollarweed) as well as a few grassy weeds (grassburrs) without hurting your St. Augustine. Another new product we have is Topshot. It also kills all broadleaf weeds in the lawn and comes in a package with 2 ampules which cover 5000 sq. ft. Simply add 1 ampule with water in either a pump sprayer or Dial n Spray to cover 2500 sq. ft.. For best results apply weed killers when weather is warm (not hot) and sunny for 3-4 days. Do not use in flowerbeds for weed control (except Image), only as a lawn application.

-DeAnna

For insect control, use Bayer Tree and Shrub Protect and Feed Liquid. Mix according to directions and drench at the base of your trees and shrubs to prevent aphids, borers, caterpillars, scale, whitefly, mealybugs and more. Plants that are prone to getting bugs, like Hackberry trees that get wooly aphids every June, Hibiscus, Jatropha and other tropicals that get mealybugs every summer, and Bougainvilleas that are constantly eaten by caterpillars can be protected by using this product. If you have ever noticed black soot on your plants, this is the product to use since sooty mold is caused by insects.

For a quick and easy craft, make Lavender Sachets! Sachets are little bags of dried herbs that freshen up your clothes, linens, or your entire closet. Once your lavender plant has produced its blossoms, cut the flower stalks and tie them together. Place the bundle in a dry and dark place for about a week (they should be dry enough to use then), then strip off the blossoms and buds. Then either sew or buy little bags of sheer material and place about ¼ to ½ cup of dried lavender blooms in each. And there you go! It’s simple and easy, and your clothes will always smell great!

You may have already done several items on this list, but with all the recent rains they may have been depleted or washed away, therefore another application may be necessary.

  1. Fertilize the lawn, shrubs, trees and tropicals again with Gill Lawn & Garden or Milorganite.
  2. Continue to feed vegetables and herbs with Espoma Plant Tone. Citrus and fruit trees with Espoma Citrus Tone.
  3. Apply pre-emergent again to prevent weeds, Amaze or Dimension.
  4. Spray post-emergent again or as needed to kill existing weeds, Weed b gon or Image. You could also keep the weeds mowed before they go to seed. Most will die with the heat.
  5. Drench Hackberry trees for wooly aphids, bougainvillea for caterpillars, hibiscus and jatropha for mealybugs etc.. with Bayer Protect and Feed to prevent insects for 9 months.
  6. Treat the lawn with Bayer Season Long Grub Control or Beneficial Nematodes.
  7. Watch for Chinch bug activity in the hot dry spots of the lawn near sidewalks and driveways. Spray with Cyonara or Triazicide. For organic control use Spinosad or Diatomaceous Earth.
  8. Treat for fungus. Check the lawn for brown patch. Roses, Crape Myrtles and Gerbera Daisies for powdery mildew and Plumeria for rust. Use F-stop, Serenade or Actinovate for the lawn and Fertilome Systemic , Serenade or Actinovate for plants.
  9. Plant sun or shade loving heat tolerant flowers and tropicals.deanna
  10. Mulch everything including potted plants to prevent weeds and hold moisture for the summer.

cherry-5I’ve always known Cherry Green is an avid gardener. Year round, no matter how hot or cold it is, she remains a gardener. Whenever I see her about town, she asks if we have this or that, and most of the time it’s not your ordinary ligustrum or Asian jasmine. A few weeks ago, she was in the store looking for pink gaura, one of my favorites, but again, not a typical Corpus Christi landscape plant. In conversation, I asked if I could come tour her garden. What a treat!

Cherry & her husband Hix moved from the Dallas area in their 20’s to a neighborhood off Ocean Drive and have been there ever since. Cherry immediately went to work designing the garden and Hix assisted her in creating her dream landscape. As with many, their original plant choices leaned toward the East Texas varieties. Through trial and error, and a few hot and humid summers, they’ve migrated to more natives, more drought tolerant, hardier plants. cherry-6Interestingly, when she acquires a new plant, she enters it in her data base by common and scientific name. In addition, she photographs her succulents since sometimes they are difficult to differentiate. I also think that could be a great way to record plant performance, bloom cycles, etc…

Cherry & Hix’s garden is truly an amazing collection of plant species. Their front yard is anchored with oaks and Natchez crape myrtles; beds are filled with bird of paradise, foxtail fern, Red Wave hibiscus, jasmines, chrysanthemums, Japanese yew, yellow plumbago and more. Their side yard includes Drift roses, Mexican oregano, exotic day lilies including Black Ambrosia & King’s Point, plumeria, hamelia, a way cool groundcover periwinkle, hibiscus and a great collection of succulents in pots by the side entrance to their home. Their back yard has beautiful mesquites, one with night blooming cereus growing up it.cherry-1 There are crape myrtles, a mountain laurel and a grapefruit, specimen plumeria, durantas, firecracker plant, irises, altheas, pride of Barbados, porter weed, night blooming jasmine, Indian carnation, milkweed, a beautiful specimen white bird of paradise, beautiful blooming gomphrena and a nice assortment of vines on their back and side fence. Again, they have a great collection of succulents in an interesting collection of containers. She jokes that her lawn is disappearing as her garden beds get larger.

Cherry has no qualms, when a plant becomes too big in its current location, to move it or dispose of it. She’s all about trial and error. A few days before our visit, she dug up an iris that had gotten too large for its space, divided it, and was readying them for planting in a more appropriate spot. cherry-3

I was most entertained by where Cherry has acquired her plants. I’m proud to say many of her plants have come from Gill’s, but I’m not sure it’s a majority. It seems many of her plants have been given to her by friends and family. Gloria Swantner has shared many, as well as B.J. Kershaw, John McKeever, Laurie Mintz, our dear John Anderson, Judy Henderson and on and on. Cherry has purchased plants from our South Texas Botanical Gardens as well as other non-profit gardens, taken a few clippings here and there from hotels (for instance, one of our favorites on Congress Street in Austin). Her daughter, Lacy, is always scouting for her mom in her travels. Bonnie Cohen even brought a suitcase of cuttings from her mom’s garden in East Hampton, New York. I’m sure these plants, given to her by friends and family, hold a special place in her heart. And you can be sure, Cherry has reciprocated in plant giving!

Cherry joked, toward the end of our visit, that she tries to garden the two days prior to trash pick-up so her neighbors don’t have to look at her yard debris for too long. I feel sure they sallyare grateful to have her in the neighborhood (anyone would with such a beautiful landscape), as I am to have her as a friend and a member of our gardening community. Thank you Cherry!
