Lawn Care

You can still apply pre-emergent weed control to your lawn to prevent more weeds from sprouting. We recommend Hi Yield Weed & Grass Stopper with Dimension

You can overseed your lawn now with winter rye grass seed (or fill bare spots with this seed) at the rate of 1 lb. per 100 sq. ft. We have it in 5 to 10 lb. bags. Just remember you cannot use a pre-emergent when planting seed.

Fertilize your lawn when it begins actively growing. This is usually late February to mid March. We recommend organic Medina Growin Green. All fertilizers require water to work, so plan on watering after you apply.

Eliminate broadleaf weeds with Image, Ortho Weed-B-Gon for Southern Lawns, or organic Capt. Jack's Lawnweed Brew once our temperatures warm to the 70’s.

Control growing weeds naturally with Horticultural Vinegar or Captain Jack's Deadweed Brew treating only the weeds. It will burn all plant foliage.

Indoor Plants


Give your indoor plants an inspection for insects. Most common are mealybugs, spider mites (not a spider), and scale.

  • White cottony stuff on the backs and crevices of the foliage: mealy bugs.
  • Spotted leaves with a sandpaper feel & tiny red specs: spider mites.
  • Black mold on foliage with waxy bumps on leaves: scale

All of these can be controlled naturally with Neem Oil or Spinosad Soap. It’s a good idea to spray/treat your plants outdoors then bring them back in once they’re dry.

Fertilize your indoor plants with organic Hasta Gro liquid and add nutrients with Worm Castings. 

Give plants a gentle wash either outdoors or in the tub or sink to remove dust

Repot anytime with good potting mix.

Invest in a moisture meter to help with watering decisions.


Annuals & Perennials

Fertilize organically with Medina Growin Green, Hasta Gro, Maestro Rose Glo, or Plant Tone.

Established Roses

Fertilize organically with Maestro Rose Glo or Plant Tone.

Established Citrus Trees

(3 years or older) Fertilize organically with Citrus Tone, Medina Growin Green, Hasta Gro, or Plant Tone, or conventionally with ammonium sulfate 21-0-0 available in 4 to 20 Lb. bags.

Cool Weather Vegetables

Fertilize organically with Medina Growin Green, Hasta Gro, Maestro Rose Glo, or Plant Tone, or conventionally with ammonium sulfate.

All granular fertilizer should be watered in well.
Do not fertilize tropicals - they need to rest.


Only as needed – but dry cold fronts, high winds and low humidity can dry plants quickly. Established lawns only need water every couple of weeks, provided we don’t get rain.
Be sure to check your sprinkler system and adjust accordingly!

Garden Guide: Good Water Practice for Established Trees, Shrubs & Lawns


Don't Prune:

Early spring bloomers such as azaleas, Carolina jessamine, Indian hawthorn, Mountain laurel or Redbud. Prune these after they bloom.

Do Prune:

Fruit trees – peaches, apples, plum, pear lightly to shape (do not prune citrus)
Hardy dormant trees – oak, mesquite, cedar elm, and crape myrtle – Do not top trees!
Perennials that have finished their bloom.
Pick spent flowers from annuals to prolong their bloom season.

Pruning Roses – do it now!

Prune established garden roses early to mid-February. Remove dead or small twiggy growth, leaving strong healthy canes to a plant height of about 18”. Try to prune back to an outward facing bud to maintain spreading, open growth. Don’t prune climbers until after the heavy spring bloom, then removing only the oldest canes and cutting back healthy, vigorous canes no more than 1/3. Cut the flowers throughout the year. This will encourage new buds to form to cut and enjoy again. 


Watch Out For

Lawn Fungus

This can be a major problem after long periods of wet, cool weather. There are 2 major lawn fungus – Take All Patch and Brown Patch.

Watch: How to Collect a Grass Sample

Read: Protect Your Lawn – Recent Take-All Root Rot Sightings

To Treat: Treat Take All Patch organically with Nature’s Blend Compost or Peat Moss, conventionally with Scotts Disease EX Lawn Fungicide or Fertilome Systemic Lawn Fungicide.

Treat Brown Patch Fungus with Fertilome Systemic Lawn Fungicide, or Fertilome F-Stop Granules.

Watch: Brown Patch Fungus

Scale Insects

Found on hardy trees and shrubs.

To Treat: Spray with Neem Oil Spray or All Season Oil

Leaf Chewing Worms & Insects

To Treat: Thuricide, Spinosad or Dipel Dust

When or if temperatures dip below freezing:

Move tropical potted plants inside or group them together in a protected area so they may be easily covered.

Mulch and water newly planted trees and shrubs well; water tropicals and potted plants.

Cover tropicals and tender plants with sheets, blankets or plastic. (Note plastic can burn the outer foliage it is touching)

Bring fabric all the way to the ground allowing heat from the soil to be trapped around the plant.

Uncover all plants as temperatures rise to prevent the foliage from scorching.

We carry frost blankets!

  1. Still read your garden news, always! Pictures are great!
    Now living in Wimberley-its lovely.Come visit.
    Hope your all doing good!

    1. I could not access the facebook article. I have been in this business over 40 years and read 3 to 5 trade journals every month. I do rarely come across an article where a worker has contracted an illness from a peat-based potting mix, so it is not unknown, but it is not common enough that I have any concern for myself, my family, or my co-workers. I just seeded 2 flats of peat-based seed starting mix with wolfberry, this afternoon. I have much more risk to be hurt or killed in just one trip driving to work than the hundreds of pottings I have done. But if you have concern, a well-fitted respirator would prevent legionairres disease, and gloves would protect cut or abraded hands from clostridium.

    1. Hi Val – we do carry Jacaranda trees. The do well if they can be protected from the cold. The dwarf varieties (like bonsai blue – we have them in stock) tend to do better here. They’re more easily protected. They get to be about 10′ tall. Lychee are probably not going to like our extreme heat and humidity and definitely not going to like cold temps.

  2. Ive have my plants protected in my garage over this cold winter season. When is a good time to start taking them outside. They get plenty of light from the windows in my garage doors.

    1. Sounds like they’re doing ok in the garage. That’s great. We don’t expect any more freezes, but there’s a chance it could happen. So, wait til Valentine’s Day to be safe.

  3. Varies quite a bit by plant type. For example, a ficus is fine outside into the mid to high 30s, but a Spathiphyllum should not go below 50°. probably everything can go out by March 1, but some things that are more cold tolerant might start sprouting and get a little stretched out if they’re not getting brighter light outside.

  4. What is a fast-growing tree for this area?

    We lost one of our Japanese Yews … both are approx. 10 ft. tall. The plant turned dark brown all of a sudden and died within 2 months. Should we destroy the remaining, living yew or keep the living yew and plant something else where the dead yew was? I’m sure our chances of finding a yew the same size as the remaining yew would be one in a million.

    1. Hi David – we can source Japanese Yews that are about 6-7′ tall. If the remaining one is still nice and healthy, you might consider keeping it and planting another. They won’t be the same size right away, but the new one will catch up.
