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.

5. Train Your Plant Sitter

Be sure to have a trusted plant-sitter come water your plants while you’re away on summer excursions! It’s a good idea to spend a little time showing them how you water. Make them a list, draw them a map, and walk them through it. You know your plants and which ones get tired and thirsty the fastest.

6. Collect Cool New Houseplants

Now’s a great time of year to work on your houseplant jungle. The greenhouse is restocked with all kinds of interesting houseplant choices, including lots of new Bromeliad varieties! Keep in mind that constant A/C indoors will dry out plants. Keep an eye on watering (use a moisture meter) and don’t place houseplants near an A/C vent. You might also try experimenting with a humidifier near your plants to help regulate moisture. 


 


 

Join us for fun and food this Saturday, July 6th! Gill’s resident pitmaster, Hidalgo, will be serving up pulled pork sandwiches with slaw, hot dogs, and veggie dogs from 11 a.m. to 2 p.m. He’ll be set up with his pit under the shade tree right in the middle of the garden center, and we’ll have places to sit and eat with cold drinks too. Free, fun, and open to everyone! See y’all Saturday!

We’ve seen and heard about lots of ants in the garden lately, which is pretty typical during our summer months. Luckily there are 2 solutions that are very effective against 2 of our most common ants:  fire ants and crazy ants!

Get Rid of Fire Ants with “Come and Get it” Bait

 

Did you know that our fire ants aka Red Imported Fire Ants came to the US on cargo ships from South America in the 1930s? Now they’re found in several southern states including much of Texas. Look for mounds of fluffy, freshly worked soil, especially right after a rain. Unlike other ant mounds, fire ant mounds don’t have a hole in the center – they enter and leave the mound via underground tunnels. Organic Come and Get It bait is an effective and safe weapon for fire ants that contains Spinosad as the active ingredient. No mixing and no watering – just sprinkle on and around the mounds and the foraging ants will take it into the colony as food.

Take Care of Crazy Ants with Diatomaceous Earth

You’ll know crazy ants when you see them – they’re tiny and they run around “crazy”! You’ll find them around patios and entry ways and especially under firewood or boards. Speedy crazy ants can be stopped with organic Diatomaceous Earth aka powder made from fossilized remains of diatoms. Sprinkle DE around the areas where you see crazy ants. As the ants pass through the DE, the DE dries out their exoskeletons and they die. Works great for fleas too!

Leave Red Harvester Ants Alone!

Harvester ants are less common in our area, but they’re the only native ant on this list. Look for a big flat bare patch with big red ants radiating from a hole the center! They look somewhat similar to fire ants, but quite a bit larger. Don’t poison Harvester ants because they are the main food source for the Texas Horned Lizard aka Horny Toad, which is now a threatened species. Harvester ants make up about 70% of the Horny Toad’s diet – they need to eat large numbers of the low-calorie ants, which is why the toads have a large stomach.

 

What’s a nativar? Simply put, it’s a plant that has been cultivated by humans, a cultivar, of a native plant species. Why would you do that? Why not just plant the true native species? Well, because plant growers and gardeners want more variety and sometimes we want to dial in certain desirable traits (shorter, taller, different bloom colors, etc.). Here are 3 examples of nativars which happen to be 3 of our fav plants for summer!

Desert Willow “Sweet Bubba”

Desert Willow is one of our absolute favorite small trees for South Texas. It thrives in low-water conditions and gives you (and our pollinators) tons of blooms to enjoy from late spring through fall. It grows to about 15 feet and prefers dry, well-drained soil. We just planted one in our new raised beds in front of Gill’s! The Sweet Bubba variety of Desert Willow has been bred for more narrow, graceful leaves, a deeper bloom color, and to have fewer seed pods to deal with.

Texas Sage “Lynn’s Legacy”

Texas Sage probably has more nativars (different varieties) than any other Texas native plant. It comes in a range of sizes, lots of different shades of sage green, with different blooms and different growth habits – many different uses in the landscape. A relatively new one that we’re super excited about is “Lynn’s Legacy”. Most varieties of Texas Sage bloom based on changes in barometric pressure just before or after a rain. Lynn’s Legacy aka Lynn’s Everblooming is not as dependent on changes in humidity and pressure. It’s bred to bloom more often and more consistently. You’ll get a nice 5×5′ sage with more upright leaves, and denser growth habit, darker green foliage, and more blooms!

Dwarf Barbados Cherry


Barbados Cherry is native to South Texas and Mexico, through parts of the Caribbean, and into South America. The true native variety is a large shrub/small tree that grows 9-18′ tall, whereas the dwarf variety stays 4-6′ tall making it more suitable for most landscapes. You’ll get lots of small pink blooms all summer followed by the fruits, which are like a cross between a cherry and an apple, hence the name Manzanita in Spanish. Great for making jelly!

We all know that fresh mulch is like a fresh coat of paint for your garden – instant makeover! But did you know that applying a proper 3” layer of natural mulch keeps underlying soil temps more than 20 degrees cooler?!

Gill’s Landscape Designer, Kathy Hubner attended a webinar presented by Bartlett Tree Research Laboratories in which they shared amazing results from a mulch study in San Antonio. Soil temperatures were measured at 6″ deep (where plant roots live) on a 105 degree summer day. Bare soil with no mulch, 6″ down was 102 degrees. Soil under grass was 92 degrees. Soil beneath a 3″ layer of mulch was only 76 degrees!! Mulch for the win!

Before a Fresh Mulch Layer…

Keeping plant roots cool helps them take up water and nutrients and prevents heat stress on the plant. Cooling alone are a great motivation to maintain a 3″ mulch layer, but there are lots of other magical powers. Mulch helps you water:  it helps retain depth moisture in the soil when you water slow and deep, and when we a good rain.

A 3″ mulch layer also helps suppress weeds. It allows good water, oxygen, and nutrient transfer, but blocks light that weed seeds need in order to sprout. And speaking of nutrients, natural hardwood mulch or pine straw mulch breaks down over time and helps build healthier soil.

After Fresh Mulch!

To achieve a 3″ layer of mulch takes about 1 bag per 12 sq. ft. Be sure you spread the mulch evenly and avoid creating the dreaded “mulch volcano” around the trunks or main stems of plants and trees. Mounding mulch up against the trunk can invite disease. Best to mulch around trees and plants then pull mulch away from the trunk to create some space.

Pro tip: As your summer veggies finish their growth cycles, pull them up and use a nice layer of pine straw mulch over your garden beds to keep weeds down and help keep your soil alive and ready for the next season. Fall veggie planting is right around the corner!

KEEP COOL AND MULCH ON!
