Garden Center Hours: Mon-Sat 9am - 5:30pm • Sun 10am - 5:30pm

Yay for May! Everything’s growing and blooming and we hope you are too! May is Mental Health Awareness Month, which is a good time to think about the peace of mind that gardening brings us. Gardeners know that all the research is true – gardening is good for you! Here are our Top 7 Must Do’s this May to keep you and your garden feelin’ good.

1. Join Us for Garden Talks and Events!

We’ve got a big May planned here at Gill’s, and we’re kicking it off this Saturday, May 3rd with a fun cyanotype printing event with the TAMUCC Student Art Association. Stop by and create your own cyanotype prints using leaves and flowers! Then next weekend we’re inviting kids to come pot up a flower for Mom for Mother’s Day. Sure to be lots of fun and lots to learn and discuss! Click here for more info and tickets!

2. Plant Blooming Perennials and Trees

It’s time to plant lots of different blooming perennials and blooming trees. Get them established in May so they are rooted and acclimated to withstand warmer temps this Summer. Staples like Esperanza, many varieties of Salvia, Lantana, and tons more are all blooming beautifully right now. And blooming trees like Vitex, Retama, and Wild Olive are looking great right now. Crape Myrtles will start blooming soon too. Added bonus:  blooming perennials and trees attract lots of butterflies and hummingbirds!

3. Plant and Harvest Veggies

Warm weather veggie time! Plant all kinds of peppers, zucchini, squash, melons, and okra this month for continued harvesting into the Summer months. If you planted tomatoes, cucumbers, and other early Spring veggies, you’ll be harvesting now or very soon. Be sure to harvest often! It keeps birds & insects from finding them first. If you do have insect issues in your veggie garden, our go-to organic control is Spinosad – safe for food but takes care of bugs. Remember to keep watering your veggies as the weather warms up to maintain depth moisture. 

4. Mulch for Many Reasons!

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?! A good mulch layer keeps weeds at bay, and as it breaks down over time, it add nutrients to your soil. And perhaps most importantly right now, a good mulch layer retains moisture, which means big water savings. 

5. Transition Your Lawn to Summer

Feed with Natural Fertilizers:  Medina Growin Green or Milorganite. Yes, you can still fertilize your lawn, even though our lawn watering is limited. Using a good organic lawn food, like our go-to Medina Growin Green, promotes root growth and long-term health, which makes lawns more tolerant of less water. Ideally you’d want to water the fertilizer in, but you don’t have to. Medina Growin Green is gentle and won’t burn your lawn. You can apply it now and water it in slowly over a few weeks. If you have trees in your yard, keep in mind that fertilizer and water need to be applied at the drip line, aka where rainwater naturally drips off the outer edge of the canopy. Therefore, if you apply fertilizer to your lawn and water it in for the trees, your lawn will get the benefit too. You can also try to time your lawn fertilizing with a light rain. We typically don’t recommend waiting for rain to fertilize since a heavy rain would wash most of the fertilizer granules away. But, given the watering limitations, taking advantage of a light rain is a good solution. 

Watering:  Homeowners can collect free effluent water at the Oso Wastewater Treatment Plant to use to water lawns, which is a great option. Apply for a quick and easy residential permit from the City of Corpus Christi here.  If you do so, keep in mind that 1,000 gallons can water 1,621 sq ft of lawn at a nice 1” depth or 3,225 sq ft of lawn at ½” depth. 

When mowing, the proper height for St. Augustine lawns is around 3 inches. For Bermuda lawns, keep mowed to around 2-2.5 inches. Buzzing lawns shorter than that will cause lawn stress, and stressed lawns are more susceptible to pests, weeds, and disease.

Watch for lawn insects & treat when needed. Grub worms & chinch bugs are easy to control when caught early but there’s no need to treat unless you have them. BioAdvanced 24-Hour Grub Killer or Season-Long Bonide Insect and Grub Control will do the trick for grubs. Diatomaceous Earth, Spinosad, or Cyonara takes care of chinch bugs. Reminder, you can bring us a grass sample any time you suspect a lawn disease or pest. We’ll diagnose (using our microscope if needed) and get you what you need to knock it out.

Consider reducing your lawn space! Does all this lawn stuff sound like a lot of work? It can be! Many of us are reconsidering whether we really even want all that green lawn space. Why not start converting small portions of lawn to planting beds filled with blooming perennials that benefit the environment and use far less water? One way to start would simply be to deepen existing landscape beds to reduce some lawn. 

6. Set Your Mosquito Traps!

We are big fans of the simple bucket mosquito trap. Just fill a bucket 3/4 with water, add a good handful of lawn or plant clippings, and toss in a Mosquito Dunk or Mosquito Bits. These dissolve in the water and release bacteria that target mosquito larvae and kill them before they hatch. And they’re organic and not harmful to birds, bees, pets or humans! Set a few of these traps, sprinkle some organic Mosquito Beater granules around walkways and patios, spray organic Cedar Repel on your lawn, and use Skeeter Screen incense sticks near where you’re working or hanging out outside. Remember that using chemical mosquito foggers kills all the good bugs too, some of which also help control mosquitos and other bad bugs.

7. Gifts for Mother’s Day and Graduations

Let us help you find something pretty, useful, or both for the gardening moms and grads in your life. Pottery, birdbaths, wind chimes, quality garden tools, hats, gloves, garden decor, plantable greeting cards, gardening books – lots of options. You can purchase Gill gift cards online here and we’ll gift wrap and mail them to your loved one. Or come find the gift that gardeners love most – plants 🙂

Fresh mulch is like a fresh coat of paint for your garden – beautiful instant makeover! But it’s not just for looks. Natural mulch has so many other critical benefits, especially as we move into warmer summer temperatures. Read to learn more about how mulch keeps plant roots healthier, adds nutrients to the soil, suppresses weeds, prevents plant disease, and very importantly right now, saves water!

Mulch Keeps Plant Roots 20 Degrees Cooler!

Did you know that applying a proper 3” layer of natural mulch, like hardwood, cedar, or pine straw 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!! Keeping plant roots cool helps them take up water and nutrients and prevents heat stress on the plant. To achieve a 3″ layer of mulch takes about 1 bag per 12 sq. ft.

Mulch Suppresses Weeds & Builds Healthy Soil!

A 3″ mulch layer also helps suppress weeds by blocking light that weed seeds need in order to sprout, while still allowing good water, oxygen, and nutrient transfer for plants. And speaking of nutrients, natural mulches break down over time and help build healthier, looser soil. For these reasons, mulch can also act as an excellent placeholder for areas that you plan to plant in the future. For example, once you harvest your spring veggies, mulch that area to keep weeds from invading and to keep soil nice and healthy for when you get ready to plant again. Or, if you’re working on your landscape in phases, go ahead and create and mulch new beds, then plant when you’re ready – very few weeds to deal with and easier digging!

Mulch Saves You Water!

The name of the game for summer watering is to maintain depth moisture. This means watering plants slow, low, and deep. Use a watering wand and water at ground level to get water down to the roots – don’t water over the top of your plants!  Also, don’t water full blast. Turn down the pressure, water slowly, and use the cycle-soak method which means water once, let it soak in, then water again to get water down deep. A proper mulch layer is your best friend for maintaining this depth moisture due to the cooling/insulating effect we’ve discussed, and because it prevents evaporation. Not only does mulch help the soil retain moisture, it also keeps soil from splashing up onto the plant when you water, which prevents fungal disease. 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 just a little space.

 

 

 

 

 

 

Here’s to summer garden fun! We’re making the transition to warmer weather with some intermittent rainfall and lots of good energy in the garden. Here are our top priorities this month, including what to plant, how to adjust watering, what to watch out for, and how to keep plant roots cool and happy.

1. Plant Summer-Loving Plants!

So many of our favorite plants for South Texas don’t just tolerate warm weather, they only begin to thrive and look their best in the summer. Think of blooming perennials like Firebush, Esperanza, and Pride of Barbados for awesome summer impact. Think of big purslane hanging baskets, Gomphrena, and Periwinkles for bursts of bright color. And browse our Texas native plant section for plants and trees that have thrived through hundreds and even thousands of Texas summers. If you’re still wanting to plant food, you can do that too – okra, basil, thyme, watermelon, peppers, black-eyed peas and more should be planted in June.

2. Keep Roots Cool with Mulch

A good mulch layer (2-3″ deep) has so many benefits. It looks amazing, keeps weeds down, helps retain moisture, adds organic matter to the soil, AND keeps plant roots nice and cool in the summer. Bartlett Tree Research Laboratories shared amazing results with us from a mulch study they conducted in San Antonio. Soil temperatures were measured at 6″ deep (where plant roots live) on a 105 F summer day. Bare soil, 6″ down was 102 F. Soil under grass was 92 F. Soil beneath a 3″ layer of mulch was only 76 F!! Mulch for the win! 

3. Water Low & Slow

We’re not talking about BBQ, although that sounds good too… We’re talking about watering low, as in as in low to the ground to avoid evaporation, and slow as in not with your hose open full-blast. This helps decrease runoff and get more water down to the roots. Consider setting up your own automatic drip irrigation system – they’re easy to DIY and they operate on the low & slow principle. Also, be sure to use the cycle & soak method, which simply means water once, let it soak in for several minutes, then come back and water again. This makes sure you’re pushing water down deep. 

Pro tip:  Use a moisture meter in your landscape beds and pots! We carry them for around $10 and can show you how easy they are to use. They have a long soil probe that tells you whether you actually have good moisture (or too much) down deep where it’s needed. They’ve saved many plants!

4. Watch for Summer Bugs, Critters, and Plant Disease

Yes, bad bugs will be around more during the Summer, but don’t treat unless there’s significant damage. We can help identify the pest and if/how to treat. You don’t want to kill too many good bugs while trying to take care of the bad bugs! If you see brown areas in the lawn that are easily pulled up, it’s usually a sign of grubs eating the roots of your grass. You can control grubs with Bonide Insect and Grub Control. Chinch bugs love hot dry areas in lawns. They make the lawn look dried out along sidewalks and pavement. Spot-treat those areas with Cyonara in easy ready-to-spray bottles. For organic control, use Spinosad or Diatomaceous Earth. We’ve also seen a lot more caterpillars than usual this spring. They’re commonly found munching on veggie gardens, but this year we’ve seen them on Gomphrena and Dichondra! Check out these big Sweet Potato Hornworms that Jesse found eating his Dichondra at night! Not too common to see, but it makes sense since dichondra is in the sweet potato family. Just a few caterpillars can be relocated, but if you have a lot destroying your plants, treat with organic Bt in liquid spray or powder form. 

5. Garden In Style Indoors with New Houseplants

We just restocked the greenhouse with all kinds of unique and classic houseplants looking for their forever homes! Time to work on your collection! We can help you determine the best houseplants for different areas and different lighting in your home. Once again – invest in a moisture meter for your houseplants, too. In our experience, the main cause of houseplant death is too much love aka too much water. Keep in mind that houseplants can also be sensitive to chemicals in treated tap water. We use as much A/C condensate, rainwater, and water from our dehumidifier as we can to water houseplants and keep them looking their best here at Gill’s.

 

 

Temperatures don’t feel like it yet, but it’s time to start making the transition into an exciting new fall planting season! There’s a lot to do in August to set yourself up for big garden success this fall and beyond. Here are our top must-do’s!

Check out our August Garden Guide for more tips and remember that trees, shrubs, and perennials can be planted 12 months out of the year! 

1. Pick Out Your Fall Veggie and Flower Seeds!

August is the time to start your fall veggie seeds! Next week, we’ll receive the new 2025-2026 seeds from our favorite seed suppliers, including heirloom vegetables, brand new releases, and wildflower seeds. Try our new Cow Pots or seed starting trays to start seeds indoors this month, move to a covered patio once they sprout, then into your garden beds once they’re robust enough to live outside. This will protect the seedlings and slowly acclimate them to outdoor temps. Our Fall Vegetable Planting Guide provides the specific seed-planting dates to help plan your fall garden. Remember – if you want bountiful fall veggies, you need to get an early start! 

2. Start Planting Now for Fall Pollinators!

Don’t wait until fall arrives to start planting for fall pollinators – start cooking now so their meal will be ready when they arrive! Important fact: birds, bats, bees, butterflies, beetles, and small mammals that pollinate plants are responsible for bringing us one out of every three bites of food worldwide. Plants attract and provide food for them to keep the cycle going. For example – plant Zinnia and sunflower seeds now, and they’ll be ready to feed migrating birds this fall. Plant salvias now, get roots established, and they’ll be gorgeous this fall and covered in hummingbirds, butterflies, and bees. If you want to provide the best benefits for the most pollinators, plant Texas natives

3. Prep Your Garden Beds

August is the time to start prepping fall veggie beds! Finish your Summer harvesting, clean out your beds, and pull weeds. To get your soil ready, we recommend mixing Nature’s Blend Compost or Cotton Burr Compost into your soil to replenish nutrients and loosen the soil before planting. About 1 bag per 12 sq. ft. is good. Once prepped, add a thick layer of pine straw or hardwood mulch, which will help retain moisture, keep weeds from sprouting, and keep the soil cooler until you’re ready to plant. As you plan your space, think crop rotation – don’t plant the same veggies in the exact same place you planted them last season, or you encourage pests and diseases. 

4. Water to Maintain Depth Moisture!

We’ve been lucky to have some well-timed rain showers this summer, which has created some depth moisture in the soil. Our goal with watering this month should be to maintain it. For lawns and established plants and trees, this means watering less frequently, but watering deeply when you water. New plantings will require water every day for the first couple weeks to get the roots established, but again, think deep drinks so the roots dive deeper. Use a water wand with a cut-off valve to make it easy on you and conserve water. Pro tip: Conserve water by watering at ground level, not spraying from above. This way, water soaks down to the roots rather than evaporating off the leaves. 

5. Mulch = Cool Roots, Dude!

Proper mulching using natural Hardwood or Pine Straw mulch has big benefits, especially during hot weather. A good 3” deep layer of mulch will keep your plants and the soil moist and cool for longer after you water or after it rains. Not just a little cooler – we’re talking more than 25 degrees cooler!! Cooler soil temps allow plant roots and beneficial microorganisms in the soil to flourish. When mulching, give the main trunks or stems of your plants a little space – mulch 3” deep throughout the bed, but no more than 1” deep right up against the main trunks/stems of plants.

6. Set Your Late Summer Lawn Expectations

In late summer in South Texas, even if you were watering quite a lot, it would be difficult to keep your lawn perfectly green. If we don’t get much rain this month, and with current watering restrictions in place, our goal shouldn’t be perfect green – our goal should be alive! If you can haul or find someone to haul recycled effluent water to apply to your lawn, you’re in good shape. Applying water once every 2 weeks at a half inch depth is sufficient. Again, don’t expect lush and green, but it will keep your lawn alive. Our lawn watering schedule is currently full, but we may be able to help connect you with others who are providing the service. Also, keep in mind that current watering rules allow you to hand-water your trees. Since trees should be watered at the drip line, watering trees properly can be a way to get some water on the lawn too. 

This is also a great time to think about whether you need or want all of your lawn space. Consider reducing lawn space by increasing your planting bed space, adding new planting areas, using native groundcover like frog fruit to replace lawn areas (pictured), or creating space for wildflower seeding – lots of other options that are more beautiful and more beneficial than a traditional lawn. 

Fall is OUR ABSOLUTE BEST TIME for planting veggies, trees, flowers, and just about everything else! We’ve got lots of fun events planned at Gill’s this month, plus everything you need to bring the fall magic to your outdoors. Here are our top must-do’s this October to set your garden and landscape up for success for seasons to come.

1. Join Us for October Events – Including Fall Plant Fest This Saturday!

We are so excited about our fall event lineup! Join us this Saturday, October 4th from 10am-2pm for our first ever Fall Plant Fest. We’ll have our friends Mimi’s Mini Farm with their farm animal petting zoo, pumpkin painting for kids, balloon animals, fall photo ops, tons of fall plant specials, lovely fall-themed drinks from The Brewery Coffee Cart, and the Smokeville Turkey Legs food truck will be here too! Check out our full event schedule for the rest of October and beyond. 

2. Plant & Feed Your Fall Veggies

Some of the best… Broccoli, Cauliflower, Lettuces, Cabbage, Carrots, Beets, Radishes, Cilantro, Arugula, Thyme, Chives, Sage, and the list goes on! October is our window for planting! Remember – veggies are heavy feeders, so it’s important to keep fertilizing throughout the season. We recommend using BioTone Starter when you plant, followed by a good organic granular like Medina Growin Green or Plant Tone on the 1st of each month, then supplement with liquid Hasta Gro on the 15th of each month. Set these reminders on your phone/calendar and you’ll have BIG harvests with plenty to cook and share.

3. Plant Trees Now for the Best Start – Citrus Too!

Successful tree planting is all about growing roots. Trees planted in fall grow more next spring & summer because they spend time all fall and winter working on their root system. Having a well-established root system also helps prepare them for hot temps next summer. Live Oak, Burr Oak, Magnolia, Anacua, Cedar Elm, & Wild Olive are some of our South Texas fav’s and we’ve been getting some gorgeous specimens, big and small. And don’t forget about citrus trees! We have a nice fall crop of lemons, different lime varieties, mandarins, and more.

4. Plant Fall Flowers Galore

Take advantage of the weather while the days are still long. It’s the perfect time to start cool weather Marigolds, Alyssum, Snapdragons, Violas, Petunias, Supertunias, Calendula, Begonias, Stocks – the flowers and colors that say, “FALL!”. Warm days help flowers develop roots so they can look their best during the cooler months ahead. Since we don’t experience dramatic changing of the seasons here in South Texas, we create that fall feeling with gorgeous fall colors!

5. Prevent Weeds + Fertilize Your Lawn 

Fertilizing lawns this month is essential for developing strong roots and healthy growth next spring and summer. We emphatically recommend organic Medina Growin Green! Amazing stuff! A 40lb bag covers 3000 sq ft of lawn, and for a small fee, we can rent you a spreader which makes it very easy to apply. Not only does Medina Growin Green work wonders on lawns, you can use it in all areas of your landscape, including your veggie garden. If you want to prevent lawn weeds, now’s the time to apply preemergent Weed Beater Complete or Hi-Yield Turf & Ornamental Weed & Grass Stopper. Remember this:  treat for weeds, wait 2-3 weeks, then fertilize. Do not use “weed & feed” products!

6. Plant for Hummingbirds and Migratory Birds

Right now is a great time to plant all kinds of blooming plants that hummingbirds and other migratory birds need. Some of our favs for South Texas are native Flame Acanthus (aka hummingbird bush), Salvias (like native Salvia greggii and Salvia leucantha), Cape Honeysuckle, native Turk’s Cap, native Beautyberry, Loquat, Firecracker plant, Coral bean – the list goes on and on. We have been covered in hummingbirds here at Gill’s!

7. Mulch Beds for Moisture Retention & Other Key Benefits

Proper mulching using natural Hardwood, Pine Straw, or our new natural GardenStraw mulch has big benefits throughout the landscape, including in veggie gardens. A good 3” deep layer of mulch will keep your plants and the soil moist for longer after you water or after it rains. When mulching, give the main trunks or stems of your plants a little space – mulch 3” deep throughout the bed, but no more than 1” deep right up against the main trunks/stems of plants. Using mulch in veggie beds also helps keep wet soil from splashing up onto your plants when you water, which prevents common fungal diseases. Not to mention…a good mulch layer will help keep weed seeds from sprouting.
