They probably are one of the easiest vegetable or fruit to plant.
The tomato in the picture is actually planted in a pot around our house. My dad plants them and they really don't need that much attention just helping them with water and some support as they grow, their stems are really soft.
What is good about planting your own vegetables and/or fruits is that you are sure of what is in it no chemicals or what so ever.
So go ahead and plant something you'll never know you've always had that green thumb after all.
