I love to garden! The key is good well drained soil. You can use a premixed kind like Miracle Grow or make it yourself out of compost,cow manure, and peat moss. Vegetables do better if water does not regularly hit the leaves so keep them away from the lawn sprinklers. I have a raised bed garden in a geometrical design but when I had a smaller yard I just mixed in the veggies wherever they would fit in my flower beds. And almost anything will do well in a pot.
I grow tomatoes, squash, radishes, peppers, cucumbers, strawberries, lettuce, carrots, mustard greens, spinach, onions, okra, green beans, and an assortment of herbs. It's best to plant onions, radish, and lettuce in February, while now is the perfect time to plant the rest.
Burpee Seed Company has a great book about vegetables and they carry any kind of seed.
One okra plant I really like is Burpee's Baby Bubba Hybrid. It only gets about 3 to 4 feet tall unlike regular okra that grows 6 feet or more. It's also a beautiful plant in the garden, produces a lot from July-November, and tastes great.
If you have any questions, feel free to PM me. I'm not an expert but I can tell what's worked for me what hasn't.
Good luck!
