Raised bed gardening is a wonderful way of efficient gardening and the self watering system can be added to raised beds to improve yields of your plants. These gardens sometimes have false bottoms which makes it difficult for the plant roots to reach into the soil for underground water. The self watering system for raised beds gives the roots a constant supply of water.
The self watering system used for raised beds has a reservoir which can hold large gallons of water. You will have to refill the reservoirs at times in order to make sure that the plants do not run dry. Even then, this system can provide water for the plants for a few weeks without a refill. This system is perfect if you are planning to stay away from your gardens or if you have a community garden and you find it difficult to swing by and water them regularly.
The self watering system in the raised beds have a wick system which can be used to carry the water from the reservoir to the plant roots. This works with the capillary action of water through the wick. When one end of the wick is dry, the moist end supplies water to it thereby maintaining a water gradient to water the plants. This bottom to up method of watering plants is a wonderful way of saving water as only the necessary water is used up and there is no unnecessary evaporation of surface water.
The raised beds keep away pests by themselves, but when the self watering system is used, the pests and disease attracted by accumulated water is also avoided. The plants stay healthy, lush and green and without you working too hard. This system is easy to set up and you can buy them all as set with the system already installed.
The self watering system in raised bed gardens provide a lot of drainage during heavy downpours and this will prevent the area around your home from getting flooded. There are also lesser chances of accumulating salts in the beds with excess water when you use this system.
