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!

  1. 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 .
