We’ve passed the halfway point for 2026…that was fast! We hope you’re having lots of fun this summer – holidays, BBQs, weekend trips, and garden projects! Here are our top must-do’s to keep your plants healthy and happy in July, including tips for planting, watering, and summer pests to watch out for.
1. Yes, You Can Plant in the Summer!
Myth: I’ve heard that you can’t plant in the summer because its too hot… FACT: Of course you can!! You can plant just about anything in our summers, including trees, as long as you have a good plan for watering. In fact, summer is a great time to plant crape myrtles because they’re blooming and you get to choose the color IRL! While we’re past the season for spring veggies like tomatoes, there are still plenty of summer veggies like okra, peppers, eggplant, and melons to plant now. If you want your own fresh pumpkins for Halloween, start ’em in July. Plus, now’s a great time to set table for the fall hummingbird migration with their fav blooming perennials like Firebush, Firecracker plant (pictured), native flame Acanthus, and Dicliptera aka Hummingbird Bush. Don’t let any myths discourage your summer gardening!
2. Watering: Think Depth, Not Frequency
Proper hydration happens when you get water down to the roots of the plant. This means watering deeply, not more frequently. Plants need long, slow, deep drinks! Encourage those roots to dive deeper for water. Even with recent summer rains (yay!!), continue to watch your watering and maintain that depth moisture. If you notice this summer that you’re having to water your potted plants a lot more often, it could be time to re-pot. As the pot fills up with roots, you end up with less soil and therefore less moisture retention.
3. Mulch to Keep Roots Cool
Another way to save water is to keep landscape beds and gardens mulched through the summer. Studies show that a good 3″ layer of mulch will keep your plant roots more than 20 degrees cooler! Not only that, a good mulch layer also helps retain moisture AND keeps weeds at bay. Healthy plants, less watering, and fewer weeds – that’s a win/win/win! It’s important to use natural wood or pine straw mulch that breaks down over time, NOT the red dyed stuff! As natural mulch breaks down, it adds nutrients and makes your soil more workable. Keep in mind, mulch is also a great placeholder. If you have areas that you plan to plant later, keep them mulched to keep weeds out and keep your soil healthy and ready to plant when you are.
4. Watch for More Bugs in Summer
This is what a mealybug infestation looks like!
Not all bugs are bad, so it’s important to know your bugs before you spray anything, even organics. A few bugs here and there is most likely not cause for alarm. If you do get an infestation, cut the plant back first, give it some fertilizer, then treat for bugs. By pruning first, you won’t have to treat every leaf on the whole plant. We see plants come back better than ever using this method. If you’re not sure about bugs or pruning, we’re here to help. During summer, watch out for mealybugs on plants like Hibiscus and Turk’s Cap, lacebugs on Lantana, and chinch bugs in the lawn – especially near sidewalks and driveways! We’ve got solutions for all of the above.
5. Yes, You Should Fertilize in the Summer!
Continue to feed plants, especially heavy bloomers and veggies through the summer. Keep in mind that strong, healthy plants are less susceptible to pests and disease. Speaking of strong, try a good liquid foliar food like Medina Hasta Gro about every other week in addition to your granular feedings about once a month. The foliar food sprayed directly on the leaves really makes those leaves stronger and more robust. Lots of gardeners like to use liquid seaweed in the summer for a similar purpose, to help fortify and summer-proof your plants. What about lawns? If you haven’t fed your lawn yet, you can still do that too. If you have, you don’t need to feed it again until the fall.

Prepare Your Garden Spaces for Fall Planting
Clean areas of unwanted weeds and debris.
Break up the soil and add organic matter like Cotton Burr Compost, and turn or till it in.
Mix in dried molasses and organic fertilizer like Medina Growin’ Green.
Water, mulch, and let it rest until you are ready to plant.
Keep it watered to encourage beneficial microbes in the soil.
Seeds of beans, cabbage, peas, winter squash, and turnips. Start in pots and then transplant to garden. Protect from intense heat and sun.
Pumpkin Seeds
If you want pumpkins by Halloween, plant your seeds by August 10th.
Bluebonnet Seeds
Sow bluebonnet seeds now for spring bloom.
Tropicals
All tropicals including allamandas, mandevillas, palms, pentas, blue daze, hamelia, hibiscus, esperanza, and plumbago will continue growing and blooming.
Summer Annuals
Annuals such as zinnias, moss rose, gomphrena, purslane, periwinkles, caladium and coleus will continue to flourish.
“House” Plants
Don’t forget that “house plants” are generally tropical in nature and love a nice shady or semi shady patio to put on the best show. Ficus, schefflera, corn plants, dracaenas, ivies, ponytail palms, and bromeliads all like heat and humidity.
Fertilize organically with Milorganite, Medina Growin Green, or Plant Tone.
Annuals and perennials
Fertilize organically with Medina Growin Green, or Hasta Gro, or conventionally with Osmocote Time Release Granules.
All hibiscus and tropical bloomers
Fertilize organically with Maestro Gro-Rose Glo, or conventionally with Hibiscus Food.
All granular fertilizer should be watered in well
Lawn Care
Organic fertilizers such as Milorganite, and Medina Growin Green are excellent fertilizers that feed plants and soil and are the best choice during hot, dry periods.
Lay new sod anytime, and Bermuda seed anytime this month.
Apply organic Nature’s Blend to yellow spots in lawn. Not too much - just a thin 1/8"-1/4" layer.
Mow as required. Keep St. Augustine cut to about 3”, Bermuda at 1” – 2”.
Apply organic Nature's Blend or Peat Moss for lawns, or conventional F-Stop granules as a preventative to brown patch fungus, which shows up as temperatures drop during fall and winter months.
Spray only growing weeds with Captain Jacks Deadweed Brew or Horticultural Vinegar. These products kill all vegetation; so protect plants from drift or over spray.
Apply organic Corn Gluten meal, or Weed and Grass Stopper with Dimension in the fall and spring to prevent seeds from sprouting. It will not control already growing weeds.
Weed B Gon or Image can be applied once we cool down into the 80’s temps. An organic option is Captain Jack’s Lawn Weed Brew.
Watch For
Masses of worms eating your oak tree.
Treat with organic Spinosad or Thuricide, or conventional Cyonara. Read: Oak Tree Caterpillars
White Flies on tropicals and perennials, especially lantana and hibiscus.
Treat with organic Insecticidal Soap,Neem Oil,Spinosad Soap, Bee Safe 3-in-1 Spray, or conventional Cyonara or a long acting drench like Fertilome Tree & Shrub
Note: Please, Please, Please, don’t kill the bees!
They are one of the best sources we have to pollinate our fruits, vegetables, flowers, and shrubs.
Planting Season!
Fall is Our Best Planting Season!
Trees, shrubs, and perennials get a great bonus when planted in fall. South Texas enjoys relatively warm soil temperatures through fall and winter, and cooler air temperatures direct the new plant to grow roots all through this time. So, a plant put into the ground in fall will grow twice as fast the following spring as one planted in spring due to having developed twice the root system, and it will also suffer much less stress in its first South Texas summer. We are lucky that we can garden year round here, but fall is our best season for planting!
Check the window lighting for your indoor plants. The sun is moving with the change of the season and may bring more or less light indoors.
Heater vents can cause blemished foliage and dry plants out more quickly. Watch your placement of any new plants coming indoors.
With cold fronts coming, plan to move your house plants indoors, if you have moved any outside during warmer weather. Provide adequate lighting & adjust watering.
Let this be your last feeding for your outdoor tropical plants that are becoming houseplants for the winter. They need to rest.
Keep watch for any tagalong critters or insects & move them back outdoors. Treat if needed.
Water your newly planted vegetables and bedding plants regularly, but take care not to overwater with cooler nighttime temperatures.
Cut back on watering your established plants and lawn as temperatures cool down, since they use less water. If you are unsure when to water, use a moisture meter to take out the guesswork.
Prune
Your hardy, woody ornamentals and tropicals only to shape, not severely.
Fall bulbs like paper whites and amaryllis, will make a spectacular show this winter and spring, and now is the time to buy them. Paper whites need to be chilled for 4 to 6 weeks in your refrigerator then planted in pots or in the ground. They can make beautiful gifts for the holidays. Be sure to get a free instruction sheet on their planting and care.
If you’re cooking for the holidays, you can still plant herbs for that “fresh from the garden” flavor. Even if you’re not cooking, they’re still fun to grow.
All plants that are especially stressed, or recently transplanted
We recommend organic Hasta Gro or Plant Tone
Water
Water your newly planted vegetables and bedding plants regularly, but take care not to overwater with cooler nighttime temperatures.
Cut back on watering your established plants and lawn as temperatures cool down, since they use less water. If you are unsure when to water, use a moisture meter to take out the guesswork.
Prune
Woody Ornamentals
Your hardy woody ornamentals to shape, not severely, so as not to encourage new tender growth.
Your fall blooming plants, like asters and mums, that have finished their bloom. Remove spent blooms from annuals, like petunias, snapdragons and dianthus to encourage more bloom.
Pansies, petunias, alyssum, dianthus, snapdragons, ornamental cabbage and kale, geraniums
Hardy Trees, Shrubs and Vines
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. Read more: Plant Hardy Trees And Shrubs Now
Christmas cactus is one of nature’s gifts for those who are gardening challenged. Just keep them dry and in very filtered light. How’s that for easy?
A beautiful holiday plant, the Christmas Cactus blooms at Christmas and also sometimes around Easter if cared for properly. Keep the plant in a well lit location (like near a window) away from direct sunlight-too much heat and light can stunt the growth and burn the leaves. It should also be away from drafts, heat vents, or other sources of hot air. Feel the soil with your fingers; if it is dry, it’s time to water thoroughly. Before watering again, check to see that the top inch of soil has dried thoroughly first. Mist leaves as well as watering the soil.
Fall bulbs like paper whites and amaryllis, will make a spectacular show this winter and now is the time to plant them.
Paperwhite Narcissus 1. Refrigerate for 4-6 weeks prior to planting. (plant around Thanksgiving for holiday blooms!) 2. Fill a clear vase with a few inches of pea gravel. 3. Nestle bulbs side by side into the gravel. 4. Add water up to the bottom of the bulb and place near a sunny window.
Amaryllis Plant in a pot or in the ground. If planting in the ground, place in morning sun and afternoon shade. Every three years in October, you can dig up and divide these bulbs as they multiply underground! Feed regularly with Hi-Yield Bone Meal every 4-6 weeks.
Indoor Plants
Bring fresh air and interest indoors. Houseplants like schefflera, sanseveria, pothos ivy, & philodendrons bring a clean organic feel to your home. While you move plants in from outdoor areas, be sure to check for insects and treat if needed.
Poinsettias indoors do best in cool dry areas with indirect light. An easy way to water them is with a few ice cubes every few days. Read: Poinsettia Care
Fertilize
BEDDING PLANTS Fertilize organically with Hastagro, Medina Growin Green, or Milorganite, or conventionally with Osmocote Time Release 14-14-14. Do not fertilize TROPICALS this month. They need to rest.
LAWN
If you didn’t fertilize your lawn in October or November, instead of applying a chemical fertilizer, we recommend you use an organic fertilizer such as Medina Growin Green or Milorganite. These products feed the grass & soil microbes slowly and naturally.
LAWN FUNGUS This can be a major problem after long periods of wet, cool weather or over watering. There are two major kinds of lawn fungus – Take All Patch and Brown Patch. Treat Take All Patch organically with Nature’s Blend Organic Compost, or Peat Moss, or conventionally with Fertilome Systemic Lawn Fungicide or Scotts DiseaseEX.
Treat Brown Patch Fungus with Fertilome F-Stop Granules.
Water
Only as needed – but dry cold fronts, high winds and low humidity can dry plants quickly.
Established lawns only need water every couple of weeks, provided we don’t get rain.
Starting in December, and more in January, harvest your lemons, limes, grapefruit, oranges, and other citrus fruits. What a great holiday gift!
If you notice any fruits with black gunk on them, it's likely honeydew from insects. Treat with organic All Season Horticultural Oil spray to suffocate any lingering insects.
Be Ready for Frost Protection!
We never know if we might get an early freeze in December, so have your frost blankets handy.
When covering plants for a freeze, make a tent to capture ground warmth - not a lollipop! The frost protection cloth should extend all the way to the ground and be pinned to the ground or, better yet, weighed down with bricks or firewood - something heavy so they don't blow away in high winds.
This is what a mealybug infestation looks like!
