Planting Season!

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!

Indoor Plants

  • Check the window lighting for your indoor plants. The sun is moving with the change of the season and may bring more or less light indoors. 
  • Heater vents can cause blemished foliage and dry plants out more quickly. Watch your placement of any new plants coming indoors. 
  • With cold fronts coming, plan to move your house plants indoors, if you have moved any outside during warmer weather. Provide adequate lighting & adjust watering. 
  • Let this be your last feeding for your outdoor tropical plants that are becoming houseplants for the winter. They need to rest.
  • Keep watch for any tagalong critters or insects & move them back outdoors. Treat if needed.

Water

Water your newly planted vegetables and bedding 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.

Prune

Your hardy, woody ornamentals and tropicals only to shape, not severely.

Summer perennials.

    I have a navel orange tree that needs help. its planted on the island. Been there since 2006. Had huge crop of oranges every year. HOWEVER, after Harvey the crop has been minimal and the fruit is poor texture/taste. Thats 2 years ago. My neighbors are missing their free oranges as well . Do you have/recommend a good citrus fertilizer and or anything else to help .
