Fall is Our Best Planting Season!

Trees, shrubs, and perennials get a great bonus when planted in fall. South Texas enjoys relatively warm soil temperatures through fall and winter, and cooler air  temperatures direct the new plant to grow roots all through this time. So, a plant put into the ground in fall will grow twice as fast the following spring as one planted in spring due to having developed twice the root system, and it will also suffer much less stress in its first South Texas summer. We are lucky that we can garden year round here, but fall is our best season for planting!

Fall bulbs like paper whites and amaryllis, will make a spectacular show this winter and spring, and now is the time to buy them.

1. Refrigerate for 4-6 weeks prior to planting.
(plant around Thanksgiving for holiday blooms!)
2. Fill a clear vase with a few inches of pea gravel.
3. Nestle bulbs side by side into the gravel.
4. Add water up to the bottom of the bulb and
place near a sunny window.

Plant in a pot or in the ground. If planting in the ground, place in morning sun and afternoon shade. Every three years in October, you can dig up and divide these bulbs as they multiply underground! Feed regularly with Hi-Yield Bone Meal every 4-6 weeks.

Treat lawns with Spectracide Triazicide, organically with Spinosad or Diatomaceous Earth Crawling Insect Killer.

Repel with Mosquito Beater Liquid Quick Kill or Mosquito Beater granules.

Please, Please, don’t kill the bees. They are one of the best sources we have to pollinate our fruits, vegetables, flowers and shrubs.


Water newly planted plants regularly, but take care not to overwater with cooler nighttime temperatures. Cut back on watering your established plants and lawn as temperatures cool down, since they use less water. If you are unsure when to water, use a moisture meter to take out the guesswork.

WATCH: Watering Basics with James


  • Fall blooming plants that have finished their bloom like asters and mums.
  • Remove spent blooms from annuals, like petunias, snapdragons and dianthus to encourage more bloom.
  • Your hardy woody ornamentals to shape, not severely (so as not to encourage new tender growth)

  1. Plumaria are going to be OK down to around 40°, but will lose their leaves. You should not pull the yellowing leaves off as that causes some damage but rather snip them off not too close, leaving 1/4” to 1/2” of leaf stem. Either bring them in or cover them if temperatures are approaching anywhere near freezing, I would say if the forecast is for Below 40.

  2. Is now a “fair to good ” time to purchase and plant roses (potted, not bare-rooted)? If so, do you have any in stock?
