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

Did you know early August is time to start your pumpkin seeds? We’re celebrating pumpkin season this year with our first-ever pumpkin growing contest! We’ve chosen the perfect pumpkin for South Texas:  Sugar Pie! Since the 1800s, ‘Sugar Pie’ aka the New England pumpkin, has been the standard for making terrific pies, soups, muffins, and casseroles. The small, 6″-7″ fruits are also good for carving decor-size jack o’lanterns.

Stop by Gill’s any time between August 7th-11th to sign up, purchase your seeds, and pick up your contest form. Contest limited to 60 participants, open to all ages and skill levels. We’ll ask you to document progress using the instructions on the form, then show up with your completed form, photos, and prize-winning pumpkin on weigh-in day at 10am on November 7th! The heaviest pumpkin wins a $200 Gill’s gift card, 2nd place gets a $100 gift card, and 3rd place gets a $50 gift card! As always, we’re here to offer you all kinds of pumpkin-growing advice along the way. You might be able to teach us a thing or two!

 

 

 

Hooray for WATER! Gardeners are thrilled to have huge inflows into our lakes and finally be able to take better care of our landscapes. Now that watering restrictions have been eased somewhat, it’s important not to try to overcompensate, but to water efficiently and effectively. Here are our tips for proper watering this summer and setting your gardens, landscapes, and lawns up for a gorgeous fall that’s right around the corner.

Very Important:  Know How Much You’re Watering!

Under the current Stage 2 watering schedule, we’re allowed to run spray irrigation systems, including hose-end sprinklers, once every other week. This is an adequate schedule for lawns even during the heat of summer as long as you’re applying a proper 1″ of water. To measure, use the old gardener’s tuna can trick. Place an empty tuna can (which is 1″ deep) out in the yard while you run your sprinklers. When it fills up, you know you’ve applied enough water. Depending on your sprinkler type, the timing can vary. For example, pro irrigation spray heads and impact sprinklers produce larger water droplets, while hose-end oscillating sprinklers produce smaller droplets and take much longer to apply enough water. Test with your tuna can to find out exactly how long you should be running your irrigation system or your sprinklers.

Slow & Deep Watering Wins


When it comes to watering, think depth not frequency. When you water deeply, you’re creating depth moisture in the soil, and encouraging roots to grow deeper. Deeper, healthier root systems allow plants to take up more water and nutrients, and allow plants to withstand dry periods. Remember, plants are not people – they don’t need drinks of water every day (with some exceptions).

Water Plants at Soil Level


Plants take up water from the roots…so that’s where we need to apply water! Watering over the top of plants opens the door for evaporation and runoff, plus water on the leaves on a hot day can create a magnifying glass effect and scorch your leaves. This is why drip irrigation and soaker hoses are great – it gets 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.

New Plantings and Pots = Water More Often


Now that we’ve preached depth vs. frequency, here are the exceptions:  new plants and potted plants! Tender new plants WILL need water every day to get their roots established. A good rule of thumb when planting is to water every day for about 2 weeks, every other day for the next 2 weeks, then about once a week after that, depending on the plant. Of course this can vary depending on temperature, sun/shade, and wind. Watering by hand is great during this establishment period because it keeps you in touch with your plants. You’ll notice which ones are thirstier and adjust accordingly. Similarly, potted plants, even those that are well-established, may need water every day or every other day this summer. Be sure you’re checking the moisture level in your pots and watering deeply.

Invest in Good-Quality Watering Tools


We carry a few different watering wands, sprinklers, soaker hoses, and drip irrigation kits that we’ve tested here in the nursery. Take it from the pros who do a lot of watering – it’s so much more fun when you have good quality tools! Perhaps the most important tool to keep handy is a moisture meter. They’re about $10, and they’re incredibly easy to use – just stick the probe down into the soil at the root ball and surrounding area, and you’ll get an instant moisture reading. This is not cheating! Moisture meters have saved many a plant here at Gill’s and in landscapes all over town.

All hardy and tropical trees, shrubs, vines and grasses. I can’t think of one that can’t be planted now!

Bulbs & Caladiums

Late spring and summer bulbs such as caladiums, and elephant ears

 

Houseplants

March is a great time to clean, trim, and feed your houseplants. As the sun becomes stronger, plants may require more waterings. Check more often. Consider repotting in Spring. Over Winter, houseplant roots can outgrow their existing pots.

Fertilize

AZALEAS, GARDENIAS, MAGNOLIAS

Fertilize organically with Maestro Gro-Rose Glo or Espoma Azalea Tone.

HIBISCUS & TROPICAL BLOOMERS

Fertilize all hibiscus and tropical bloomers organically with Maestro Gro-Rose Glo, or conventionally with Hibiscus Food.

ALL TREES & SHRUBS

Fertilize organically with Milorganite, Medina Growin Green, Plant Tone, or Hasta Gro. 

ANNUALS & PERENNIALS

Fertilize organically with Medina Growing Green, Hasta Gro, Maestro Rose Glo, or Plant Tone, or conventionally with Osmocote Time Release Granules.

ESTABLISHED ROSES

All granular fertilizer should be watered in well.

Prune

  • All dead and freeze damaged wood from hardy and tropical trees, shrubs, vines and perennials
  • Wait to prune early spring bloomers like Azaleas, Carolina Jessamine, climbing roses, Texas Mountain Laurels, and Indian Hawthorn until after they finish their bloom.

Water

  • During current drought restrictions, you CAN hand water everything except for your turfgrass lawn. You CAN use drip irrigation on your watering day every other week. And you CAN still apply for a temporary watering rules exemption to get new plantings established.
  • Keep in mind - outdoor potted plants dry out quickly, as do hanging baskets and small annuals.
  • Mulch all plants and trees to help hold moisture. Don't mulch right up to the trunks/main stems of plants - give them a little breathing room. And never create a "mulch volcano" against tree trunks!
  • Catch rainwater and A/C condensate to help conserve water - plants love both!

What to Watch Out For

Protect your Lawn from Oak Leaves

Live oaks are following their natural pattern of dropping old leaves before the new leaves come on. Now it’s time to get those oak leaves off your lawn before it suffocates the grass. Under large oaks, since the grass is often thin and stressed anyway because of shade, using a blower is less stressful on the weak turf than a rake.

Control Aphids, Pillbugs, & Caterpillars in Your Veggie Garden

Keep organic Spinosad soap handy for Aphids and Pillbugs, or release some ladybugs. Caterpillars can be controlled organically using Bt (Thuricide spray or Dipel dust). Inspect your veggies every day and you'll catch most pests before they become a problem. 

 

Lawn Care

Rethink Lawn Spaces

Given our drought situation/lawn watering restrictions, many of us are deciding to reduce lawn space. Traditional turfgrass lawns require lots of water and they don't provide much, if any, benefit to pollinators. Plus, much of our lawn space sits unused. Does every square foot need to be turfgrass, or could you create new beds for blooming perennials? Could you convert areas to native groundcovers like Frogfruit? Could you add some nice pathways or seating areas with a nice firepit? So many options!

Weed Control

Given our drought situation/lawn watering restrictions, decide whether you really want to control weeds. Weeds are green and they don't need much water! Plus they'll help keep the ground cooler. Many of us are choosing to mow the weeds down to keep them from reseeding rather than spraying or removing them. 

If you do need to spray/control, spot treat existing weeds growing now with natural horticultural vinegar or Captain Jack's Deadweed Brew. Both will burn any foliage so take care to not spray your plants or lawn. 

If you want to prevent weeds, apply Hi Yield Grass and Weed Stopper or Weed Beater Complete to help control existing weeds and prevent new ones.

If you want to kill existing weeds, apply Weed-B-Gon for Southern Lawns or Image once our weather warms up to 70-80 degrees with no rain for about 5 days. They are safe for Floratam & Raleigh St. Augustine and Bermuda. Give them 2 weeks to fully work and then it should be time to fertilize the lawn. This is why we don't recommend or sell "weed & feed" type products. Take care of weeds first, then fertilize. 

Fertilize

Fertilize when the grass is actively growing. You can't be too late, you can only be too early in spring. Apply organic Medina Growin Green or Milorganite and water in well (approximately 30 minutes per area). Normally, we wouldn't recommend trying to time your fertilizing with rainfall, since heavy rains can wash away the fertilizer. However, given current watering restrictions, try to take advantage of a light/moderate rain. Lay new sod anytime, bermuda seed anytime this month.

Pro Tips for Houseplants

  • If your houseplant looks unhappy, think location first. It may need to be moved to a different spot with different lighting.
  • Keep them away from the AC vents (they like humidity and the AC dries them out)
  • General rule for watering; water well then re-water once the soil feels dry to the touch
  • Spring is time to start fertilizing your houseplants. Your plants will love organic Hasta Gro
  • If they are getting too big for their pots, bump up to a slightly larger pot.

Feed organically with Medina Growin’ Green or Milorganite. Organic lawn food is best for long-term root and soil health.

Eliminate broadleaf weeds

Treat with Ortho Weed B Gon for Southern Lawns for broadleaf weeds, Image for grassy weeds and sticker burrs.

If you treat for weeds, wait 3 weeks before you fertilize.

Water

*While turfgrass lawn watering with city water is prohibited during current watering restrictions, residents can use free reclaimed water from the Oso Wastewater Treatment Plant. Apply for a permit here. Residents can also hand water trees, which should be done at the drip line, therefore lawns can get some benefit from good tree watering.

Water

– When watering during periods of windy dry conditions, it’s important to water slowly and deeply. Be sure to watch the spray of sprinklers and adjust accordingly with the wind.

– Water all plants well after planting and regularly through the first year. Plants will begin to use more water as they grow and bloom. Outdoor potted plants dry out quickly as do hanging baskets and small annuals. Check new plants daily for water needs, many will need water every day.

– Mulch around trees and flowerbeds to conserve moisture.

– Make arrangements for someone to water if leaving for more than 2 days (especially new plants).

– Watch your perennials. Check soil moisture before watering. Many plants can die from over watering. Use a moisture meter when in doubt.

Lawn Care

Fertilize early in the month, if not already done

Fertilize organically with Milorganite or Medina Growin’ Green to your lawn and water in well, approximately 30 minutes per area.
