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!

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 Cow Pots (cattle manure 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.

 

 

 

Start your engines…fall planting season is here!! September is the best time to plant almost everything – veggies, trees, shrubs, natives, hummingbird plants, and more. Here are our top 7 must-do’s in September as we head into fall, our favorite South Texas gardening season!

1. Ready, Set, PLANT Veggies, Herbs, Citrus, and Fruits!

It’s time! Tomatoes, peppers, & warm weather edibles should be planted early in September at the latest. Plant cool weather veggies & herbs anytime in September and remember to shelter them from still-intense sun and keep watered. When planting, you can’t go wrong with organic BioTone starter fertilizer + a good handful of Earthworm Castings. Neither of these require precise measurement, and they make an incredible combo for building stronger, deeper roots, preventing pests, and creating an active soil environment for plants to thrive.

Here’s our Fall veggie planting schedule. And save space for citrus trees, figs, and other fruit trees to round off your garden grocery store! They’ll all be arriving before or right around mid-September. 

2. Make Way for New Growth with Light Pruning and Clean-up

Chances are you have established plants that could benefit from a clean-up after working so hard all summer. Wait until about September 15th and give them a light pruning to make way for new growth this fall. A good rule of thumb for most plants is to prune up to 1/3 (not more) in the fall, then wait until January to do a heavy pruning/cutback. If you have questions about how to prune specific plants, you know who to call! 

3. Plant Trees and Shrubs for the BEST Start

Plants that are cold hardy (trees and woody shrubs) will benefit greatly by planting during our fall season. They’re under less heat stress, and they grow more roots through the fall and winter, making them stronger and ready to take off next spring. More roots, stronger plants, and less watering! Oak trees, Crape Myrtles, Hawthorns, Yaupon Holly, Plumbago, Boxwoods and a host of other trees and shrubs should be planted starting this month for the best possible start.

4. Plant to Support Pollinators!

We’re bringing in lots of new plants this month with our pollinator friends in mind! While you’re choosing what to plant, consider adding Texas Natives like Turk’s Cap and Lantana that birds and bees love. If you want to attract and support butterflies, try native butterfly weed (Asclepias tuberosa), Gregg’s mist flower, and lots of different blooming salvias. So many gorgeous options! Bring in some pictures of your outdoor space and we can help you plan the perfect pollinator garden – big or small. You can DIY or we can plant it for you!

5. YES You Can & SHOULD Water!

We’re in such a better water situation than we were last summer/fall! You can and should be watering regularly. Under current Stage 1 rules, you can use spray irrigation or hose end sprinklers once a week on your trash day. This is a great schedule for lawns for the month of September. Just be sure you’re applying about 1″ of water each time. As we move into October, cut back lawn watering to once every other week, depending on rain. Hold off on fertilizing lawns until October. For landscape beds and gardens, drip irrigation, soaker hoses, and long watering wands are great – you get water right down to the roots with almost no evaporation. Under current watering rules, you can run drip irrigation systems any day before 10 and after 6. But keep in mind, a good deep drink once a week is better than short durations every day. One more thing – if you want to make the most of your water, be sure to mulch! A good 2-3″ layer of fresh mulch this month will look great and be very effective for retaining moisture when you water. 

6. Set the Table for the Fall Hummingbird Migration!

Ruby-throated hummingbirds will soon make their way through for the fall migration! These tiny birds are BIG eaters. They stop here in the Coastal Bend to fuel up before their non-stop flight across the Gulf of Mexico. Host them in your yard by planting some of their favorite foods! Hummingbirds find plants using their excellent vision and are attracted to bright colored blooms, which indicate a high-sugar food source. Some of our favs for South Texas are Flame Acanthus (aka hummingbird bush), Salvias (like native Salvia greggii and Salvia leucantha), Cape Honeysuckle, Firebush, Firecracker plant, Coral bean – the list goes on! Plant a few of these and hummingbirds will find them. And don’t forget to visit the Rockport-Fulton HummerBird Celebration September 17-20!

7. You’re Invited! Fall Garden Talks and Events at Gill’s!

Gill Garden Talks and Events are back this Fall! We’re kicking it off with DeAnna and Wyatt’s Fall Veggie Gardening Talk on Saturday, September 19th!  We’ve got all kinds of fun planned including a houseplant propagation workshop on September 24th and our 2nd Annual Fall Plant Fest on October 10th, .
