Watering
Because container gardens have greater exposure to sun, wind, and heat, they need to be watered more frequently than a garden bed. Smaller containers may need to be watered as often as once or twice a day, depending on weather.
However, overwatering can be a problem if the soil is kept too wet too often. Feel the soil with your fingers, and then water when the top inch of soil feels dry. Be sure to use enough water so some excess runs out of the drainage holes. This will help ensure the entire root area is moistened. Peat moss is very difficult to wet once it becomes dry, so frequently check soilless media
