Container vegetable gardening has a ton of benefits for anyone looking to grow plants. The reason I garden with strictly containers is I rent a house and the soil is very poor in the backyard. There is no drainage at all and it is all clay with a lot of rocks, so container vegetable gardening is a great solution.
One of the most important things with container gardening to take into consideration is the size of your plant is going to be very directly related to the size of your container.
