The Harris County Extension Agency has a few Spanish-language gardening resources available online. You can find links to the PDF files here for advice on tomatoes, chiles and fruits.
The Master Gardeners down in Galveston County have put together a “Bilingual Guide to Yard Care” which is another good Spanish-English translation resource for your gardening vocabulary.
The Texas Agrilife Extension Bookstore also has Spanish-language materials on a variety of topics.
