Gardening in the City

Last week at a nearby park there was a Green Fair. You could buy anything organic from a t-shirt (organic cotton) to coffee (I stocked up). I also decided to try out gardening. There were vegetable plants and herbs for 20 baht each. So I bought sweet basil, parsley, kale, water chestnut, lettuce and a tomato plant. I also bought a few other plants to fill in the spaces of my newly painted patio. Here's a few photos. Any advice on gardening? My only experience is when I lived with G & S on Marietta Run Rd. I LOVED eating vegetables I'd just picked! Hopefully I'll have the same experience here.
