Hello, Gary from north Central Texas. Looking to learn something about gardening. Haven't planted a full garden in a good while, mostly due to age, 72. Can't hardly handle a tiller anymore. Tried above the ground for a while, worked okay for two or three years. Tried pots on the back porch for a while. Not a lot of luck. Had trouble growing tomatoes. Last year just planted a cactus, so far it's still with me. Our soil is mostly clay, seems to grow rocks.
