Plants can be moved around easily, to be changed or revived as you like and to be enjoyed at close range. The cardinal rule for planting in pots is that the plants depend on the gardener to live. They can't get anything out of the soil, so you must provide it all. Watch them for a while and see what they demand. Mike Davis, owner of The Garden Room in Milwaukee, agrees that you must be willing to make a commitment.
Maintenance is a big factor in container gardening.
There's more exposure all the way around. You may need to water on a daily basis, depending on the plant. Your first consideration is light levels. Screens, lattice or trellis placed near the plants can reduce light intensity or protect them from the wind. The duration and intensity of light is also important when you select your plants.
