I want to start...

...a garden. I have a small portable greenhouse (a shelving unit with a jacket), and I want to start some seeds. I don't have a great place to plant them, so I am going to plant in containers. I have tomatoes (for a topsy-tury upside down thingy that I am excited about), corn, pumpkins, green beans, herbs, and some pretty flowers. sounds nice, right? Well, I have NOOOO idea how to grow a garden. I have a black thumb in the extreme! I know I can grow things. I had a plant that I grew off of a cutting and kept alive for years...till my magical mommy got ahold of it. It saw her, and died, I swear. So, somewhere I have the talent, but I don't know where. If anyone has any suggestions for me, feel free to let me know; I need all the help I can get. UPDATE: I really want to start a garden this year. But, again, I really don't know where to start. Seeds? Tried that and it turned into a sad science experiment wherein no matter how much or little I watered my plants, how much I lovingly talked to them or hatefully screamed, they all looked like 6 foot tall bean sprouts. Not one of them got past the Cotyledon stage, though all grew very tall. Am I plant retarded? Well, I bought a juvenile Lavendar plant...she is the first in my garden this year, let's hope she is the first of many healthy plants that love me!
