houseplants

If your houseplants are looking more “meh” than marvelous this summer, you’re not alone. Even indoor plants can suffer during the dog days of summer—despite being pampered with filtered sunlight and sweet Spotify playlists. So what gives? Let’s dig into a few sneaky summertime stressors that could be behind houseplant decline—and how to help them bounce back!

1. Heat Stress: It’s Getting Hot in Here

Just because your plants are indoors doesn’t mean they’re immune to the heat. Summer sun streaming through windows can turn your cozy home into a makeshift greenhouse. Even indirect light can become too intense.

What to do:

  • Keep an eye on plants near south- or west-facing windows.

  • Use sheer curtains or move light-sensitive plants like ZZ plants and Ferns a few feet back.

  • Water early in the day and check more often—plants dry out faster in the heat, even though they’re indoors. 

2. City Water Blues: Chlorine Is Not Plant Food

Some houseplants are a little… picky. Corpus Christi tap water is treated with chlorine and fluoride—both of which can stress sensitive roots over time. Many houseplants are fine with City water, but others like Calatheas and Peace Lilies can’t handle it very well. Yellowing tips or brown leaf edges could be a clue.

What to do:

  • Let tap water sit out overnight before watering, so chemicals can dissipate.

  • Use filtered, distilled, or rainwater for sensitive plants when possible. An excellent and plentiful source of filtered water in the summer is A/C condensate – find a way to catch it! Here at Gill’s, we use a lot of A/C condensate as well as water collected from dehumidifiers. 

3. Too Much A/C = Arctic Tundra Vibes

Speaking of A/C, your plants might not be vibing with your love for cool comfy temps. Sudden drafts, drastic temperature drops, and bone-dry air from constant cooling can seriously mess with their tropical disposition.

What to do:

  • Avoid placing plants directly in the path of vents.

  • Group plants together to boost humidity, or use a small humidifier. 

  • Watch for wilting or leaf curl—these could be signs your plant is cold and dry, not necessarily thirsty.

4. Mealybugs: The Cottony Party Crashers

These tiny white fluffballs are a nightmare. Mealybugs hide in leaf joints and suck the sap out of your plants, leaving sticky residue and sad, droopy leaves in their wake.

What to do:

  • Check leaf undersides and stems often. Look for a nasty, cottony mess. 

  • Isolate affected plants – don’t let mealybugs spread through your whole collection!

  • Spinosad Soap or Neem Oil can be used to kill these pests. Multiple applications may be needed. Thorough coverage is a must, and we recommend spraying once a week for 2-3 weeks to make sure you have killed them all.

5. Spider Mites: The Nearly Invisible Invaders

If your plant leaves are speckled, dusty, or webby, spider mites may have moved in. These tiny arachnids thrive in dry indoor air—yep, another A/C side effect.

What to do:

  • Increase humidity around your plants.

  • Spray leaves (top and bottom) with Spinosad Soap. 

  • Wipe down leaves gently and keep monitoring—mites multiply fast. Repeat applications until spider mites are gone. 

Give Your Houseplants a Summer Spa Day

Mid-summer is a great time to give your houseplants a little TLC:

  • Dust their leaves so they can breathe (and photosynthesize!) better.

  • Trim off dead or yellowing foliage.

  • Repot if roots are circling or soil is old and compacted. If you notice you’re having to water a lot, it could be a sign that there are more roots in the pot than potting soil – time to repot!

  • Use a moisture meter! Overwatering has killed more houseplants than underwatering. Use a moisture meter to take away the guesswork. 

  • Fertilize your houseplants with liquid Hasta Gro. It works great and it doesn’t stink…great for indoors!

  • Show some love and speak kind words—the plants swear they can hear you.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

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. 

Are you as ready as we are to get outside and garden?! If the Mesquite trees are right, Spring is just around the corner. Here’s our top 6 to focus on in February to kickstart an amazing Spring season.

Check out our February Garden Guide for more tips and remember that trees, shrubs, and perennials can be planted 12 months out of the year! The only difference is the amount of water they need depending on temperatures and wind!

1. Be Ready for Cool Weather and Start Planting!

Keep your eye on the forecast for cold snaps like we’ve had this week, but don’t delay your planting projects. We are already seeing Mesquite trees start to bud up, which almost always means no more hard freezes! As James Gill shared with us at his garden talk last weekend, he’s only seen 2 years out of almost 70 where the Mesquites were wrong on this. That’s a lot more accurate than the weather man!

2. Start Your Veggies!

Beloved tomato growing is rewarding and can be challenging. Planting them early this month is important. Tomatoes need cooler nights to have good fruit set. When you plant tomatoes, be sure to install a tomato cage while they’re small. It can act as a frame for cold weather protection (a bag or blanket) if needed and a frame to support your plants as they grow. You can go ahead and start other favs like squash, cucumbers, beans, & lettuces/greens either by seed or transplants too. Stop by and we’ll help you plan your veggie garden and get you everything you’ll need for a bountiful harvest!

3. Come Learn and Share Houseplant Tips This Saturday!

This Saturday, 2/4/23, we’ll be inside greenhouse here at Gill’s, having an open and interactive discussion about how to care for your indoor plant friends. Join us for Houseplant Jungle with Ori Roldan, Gill’s houseplant connoisseur and assistant buyer. Ori will share lots of care tips and demonstrate easy ways to propagate. Bring your questions or share your plant knowledge as we hang out and talk about everything houseplants. One attendee will win a $100 Gill’s gift card, and we’ll do some other giveaways too!

4. Feed Veggies & Flowers

Blooming plants need food! Veggies are especially heavy feeders – they need to be able to sustain blooming and producing fruit. We recommend mixing in a little Bio-Tone Starter when you plant, which contains mycorrhizal fungi that promotes root growth. Then feed with a good organic, granular plant food like Plant-Tone or Medina Growin Green once a month, and supplement with liquid organic Hasta Gro in between. An easy way to remember this is to set an alarm or calendar event for granular feeding on the 1st of the month, then Hasta Gro on the 15th. These will add nutrients to your plants and keep your soil alive and healthy too.

5. February = Time to Prune!

February is the time to get plants cut back to make way for big spring growth! Most perennials like Lantana, Turk’s Cap, and Salvias need a good pruning back to about 4-8″ – don’t be shy! For any plants with woody stems/branches (like Esperanza and Hibiscus) that look dead or damaged, do the scratch test before pruning. Start up high and scratch with your fingernail, a dime, or the back side of a knife. Don’t scratch too deep. If you see the bright green cambium layer (like the photo), that means it’s still alive! If you see brown/gray when you scratch, keep working your way down the plant until you see green. That will tell you where to cut. As always, contact Gill’s if you’re not sure or have questions about whether or how to prune specific plants.

6. Keep Watch for Winter Insects

Scale is a hard bodied sucking insect that looks like a brown booger stuck to the leaves of plants. Some of their favorites are Burford Holly, Bird of Paradise, Flax Lily, & Irises. They are easily controlled with a spray of organic All Seasons Oil Spray, but it must be done now. The oil spray literally coats and suffocates the the eggs that are waiting for spring to hatch. It’s also good for treating indoor plants that may have scale or spider mites. 

Check out our February Garden Guide for more tips!

There are a wide variety of pollutants released in your home by furniture, paint, carpet, household cleansers, even gas cooktops and hot water in the shower, that can trigger illnesses, asthmatic attacks, and allergic reactions.

Plants have been found to be very effective in purifying the air in a safe, clean way. The NASA Clean Air Study conducted by the National Aeronautics and Space Administration in 1989, seeking ways to clean the air in space stations, and several subsequent studies by others, found that all plants, besides removing carbon dioxide and producing oxygen, can also eliminate varying but significant amounts of benzene, formaldehyde, trichloroethylene, toluene, and ammonia. More recent research has shown that in addition to the plants, micro-organisms in potting soil also eliminate pollutants and improve air quality.

Since most of the best air purifying plants originate in tropical and subtropical climates, they do well in our local climate and can flourish in household light. Palms, ferns, even blooming plants, and especially ivies are all helpful, but the three top air purifiers are Peace Lily (Spathyphyllum), Sansevieria (Mother-in-Laws Tongue), and Dragon Tree (Dracena marginata). You can find all three of these and many other excellent air purifiers at Gill’s.

So do yourself and your home a big favor, purify the air and bring beauty indoors with houseplants. Come to Gill’s and we will be happy to help you find the perfect plants for your home and that breath of fresh air!

It’s time to transition our gardens as we leap into Summer! Here’s our top priorities for June, which include joining us for DeAnna’s garden talk this Saturday, June 4th at 10am. Bring your questions!

Check out our June Garden Guide for more tips and remember that trees, shrubs, and perennials can be planted 12 months out of the year! The only difference is the amount of water they need depending on temperatures and wind!

1.  Join us for ‘Summer Garden Tips’ Garden Talk

This Saturday, June 4th at 10am, DeAnna Baumgartner, Gill’s manager, master gardener, and Texas Certified Nursery Professional with 40 years of Coastal Bend gardening experience will share her best tips for Summer gardening. She’ll cover Summer planting, proper watering techniques, identifying and treating pests and other issues, fertilizing, and lots more. Bring your questions – DeAnna’s got answers. One attendee will win a $100 Gill’s gift card! 

2. Plant heat-loving Summer color!

Revamp your old Spring annuals with some eye-popping, die-hard flowers for Summer. Flowers like Purslane, Zinnias, Moss Rose, Periwinkles, and Sweet Potato Vine will need water but thrive in our Summer heat. Try adding spineless Prickly Pear, Texas Sage, and other Summer-lovers that add color and form to landscapes.

3. Water… don’t go by the calendar!

With recent rains AND warmer weather, we need to be extra mindful of watering properly. That means we can’t rely on the calendar to tell us when to water. We need to pay closer attention to plants and check to be sure they need water. Pro tip:  Use a moisture meter! We carry them and can show you how easy they are to use. They’ve saved many plants! When it’s time to water, do it in the morning before 10am. Keep the water on the plants, soil, lawn, flowerbeds, not in the gutter, sidewalk, or street. Sprinkler systems are great for established lawns and landscapes but turn them off when we get rain, so you don’t over water and encourage fungal issues. Summer lawns need about 1 inch of water once a week.

4. Houseplants Inside aka Tropical Plants Outside!

Houseplants are beautiful indoors & help rid the air of pollutants from fabrics, carpets, paints, and other household items. They also look spectacular outside on a shady patio set in pretty pots. Check out Sansevieria, Philodendron, & Hoya varieties for easy care and big impact! Pro tip:  if you have a sad houseplant, try moving it to a shady spot outside for a few days to get some fresh air.

5. Watch for Summer lawn bugs!

Yes, they will be around more during the Summer. Treat the lawn with Bayer Season Long Grub Control if you see brown areas in the lawn that are easily pulled up, usually a sign of grubs eating the roots of your grass. Chinch bugs love hot dry areas in lawns. They make the lawn look dried out along sidewalks and pavement. Treat with Cyonara in easy ready-to-spray bottles. For organic control, use Spinosad or Diatomaceous Earth. Remember that healthy lawns are less susceptible to damage from bugs, heat stress, and common lawn disease like Take All Root Rot. Water lawns deeply (a good 1”) once a week this Summer and fertilize every 3 months. If you fertilized in April, wait to feed again in July.

6. Crape Myrtles – Choose While Blooming!

Crape Myrtle trees are just starting their Summer bloom cycle. Best to choose your color now while they’re in bloom, then plant and enjoy them for years to come. You must plan to water them or check them every day during this Summer. Crape Myrtles are water-needy when first planted. 

Lots of fun to be had this Summer – holidays, BBQs, weekend trips, and landscape projects! Here are our top must-do’s to keep your plants healthy and happy this July.

Check out our July Garden Guide for more tips and remember that trees, shrubs, and perennials can be planted 12 months out of the year! The only difference is the amount of water they need depending on temperatures and wind!

1. Watering: Think Depth, Not Frequency

Proper hydration happens when you get water down to the root ball of the plant. This means watering deeply not more frequently. Run irrigation systems or sprinklers once a week before 10am or after 6pm per current city watering rules – this is what we recommend for summer watering even when restrictions are lifted. Long, slow, deep drinks for plants, trees, and lawns!

2. 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. Don’t just write it down, walk them through it. You know your plants and which ones get tired and thirsty the fastest.

3. Collect Cool New Houseplants

Now’s a great time of year to work on your cool indoor jungle. The greenhouse is restocked with all kinds of interesting choices, including the pictured Hoya macrophylla aka “wax plant” or “honey plant”. The variegated edges become vibrant pink with more sunlight, and it blooms beautiful fragrant star-shaped flowers. Great to hang/drape in medium to bright indirect light. 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. We are experimenting with a small humidifier on one of our indoor plant shelves.   

4. Make Shade!

We find lots of uses for shade cloth here at Gill’s. It’s great for shading plants, of course, and can also be used to block wind. It’s also an excellent addition to a pergola, breezeway, or outdoor dining area to create some extra shade this Summer. Easy to cut to the custom size/shape you need.

5. 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 probably 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.

November in South Texas is all about spending time outdoors and gathering with family & friends. Cool weather, crisp evenings, outdoor fires & a beautiful garden… a welcome invitation. Here are our tips to help.

Check out our November Garden Guide for more tips and remember that trees, shrubs, and perennials can be planted 12 months out of the year! The only difference is the amount of water they need depending on temperatures and wind!

1. Spruce Up With Fall Flowers

Here’s our list of Fall/Winter flowers – tons of choices for outdoor color to redo pots & inground plantings. Flowers take a little time to grow and bloom. Plant early this month so they can be WOW for the holidays! Once they’re all planted, give them a good meal of organic Plant Tone or Hasta Gro.

2. Plant Trees and Shrubs

Now is the best time to plant cold-hardy shrubs and trees. They grow & develop a good root system for better success next Spring and Summer. They will need water & care, just not as much as during warmer seasons. Always fertilize when you plant and follow our watering instructions.

3. Last Chance to Feed Your Lawn!

Fertilize now if you have not done so this Fall. Our top choices:  Medina Growin’ Green or Gill Lawn & GardenFood. Apply pre-emergent for winter weed control & treat brown spots in lawns with peat moss or Nature’s Blend Compost to help with fungus control. You can also lay new sod or overseed with winter rye grass in lawn areas that are unsightly.

4. Freshen Up Inside and Out

Time to freshen up before the guests arrive! If you have houseplants that aren’t looking their best, take them to a shady spot outside on a warm day to get some fresh air. Some fresh air + a shot of liquid Hasta Gro works wonders for houseplants. There’s plenty to do outside too:  pull weeds, trim shrubs a little to shape, rake beds, then feed your plants with a good organic fertilizer such as Plant Tone or Rose Glo. Finally, add new mulch to give everything a polished look! Water once a week if we don’t get rain. 

5. Fall Herbs For Holiday Cooking

Cooking without herbs would be such a waste of thyme! Sage, Rosemary, Cilantro, Parsley, Fennel, Dill, (and Thyme) are just a few herbs that thrive in our Fall & Winter months. Limited space? A sunny spot, container & a few favorite herbs is all you need. We can even pot them up for you. 

How is it December already?! Time flies when you’re having fun in the garden. Here are our top to-do’s this month:  what to plant, gift ideas, Winter watering advice and more.  

Check out our December Garden Guide for more tips and remember that trees, shrubs, and perennials can be planted 12 months out of the year! The only difference is the amount of water they need depending on temperatures and wind!

1. Plant These Now

There’s always the BEST time to get plants growing and here’s a few that LOVE this season as much as we do!

Strawberries…who could resist picking these sweet jewels in the Spring?

Onions…we grow short-day onion varieties here in South Texas. Lucky for us the 1015 Texas Supersweet is one of those along with tasty Texas Early White & Southern Belle Red.

Roses…. our mild winters are perfect for big, beautiful roses & the cooler temps will only make them prettier and the flower color richer. Need we say more?

Trees…shade, flowering, small, big, they all benefit from planting now. Good root development during the cooler months of winter gives them better growth in spring and a fighting chance next summer.

2. Think Gifts That Grow

With a few simple components you can create heartfelt gifts that will last and grow. Collectible houseplants, succulents in natural clay pots, colorful flowers in a hanging basket, winter bulbs like Paperwhites and Amaryllis…the possibilities are endless! Adorn your wrappings with fresh herbs from the garden for those special touches that mean so much! Need ideas? We’ve got plenty!

3. Alternative Trees for Holidays and Beyond!

If you want a Christmas-y tree to enjoy in your landscape after the holidays, Junipers, Norfolk Pines, Loblolly Pines, Magnolias and Ficus trees work beautifully. We even had a customer this season who decided on a large Queen Palm to decorate! If you bring these in for decorating, be sure they have good bright natural light. Keep watered but not too much, and as soon as the holidays are done…take them outdoors for a breath of fresh air and plant.

4. Plant, Feed, Water Winter Flowers

Winter flowers are AMAZING right now! Violas and Pansies are breathtaking and Geraniums are full of buds and blooms. All that blooming makes them hungry, so take a moment and fertilize your beauties. We love Plant Tone and or Hasta Gro. Both are organic and give you big results. Have that “one more empty pot” to fill?

5. Check Irrigation and Reduce Watering

Established lawns and landscapes (those more than 2 years old) can do with less water during winter. Even potted plants will stay moist longer this time of year. Check your irrigation systems to run less time and/or less often. Water lawns every 2 weeks if no rain. Water your landscape and potted plants when the soil feels dry. YOU WILL NEED TO WATER when we have cold fronts with low humidity and high winds and/or freezing temps.
