I know nothing about gardening. I have an avocado plant, from pit, still in a glass of water. The sprout is about 8" high with 4 small leaves now, and I want to transfer it to the ground in our backyard here in Central Florida. I've read that it should be pruned at least once before planting. How exactly do I prune, to ensure a large, healthy avocado tree that (hopefully) one day may bear fruit? Some leaves? All leaves? Where? Thanks, in advance for any/all help!
