How to Water a Raised Garden

Raised bed gardening has a lot of advantages, such as less weeding and accessibility to vegetables or flowers. Since the soil in these beds drains easily, proper watering in a raised bed can be problematic. Because of the high drainage properties in these beds, it may be difficult to over-water, but under-watering is probable. To prevent under-watering, small and frequent applications produce the best results. Drip irrigation is the best way to water in these situations.

Instructions

Things You'll Need

• Plastic garbage can and lid
• Drill
• Drip irrigation line
• Plastic sealing compound
• Female end fitting with screen
• Screwdriver
• Hose clamp
• Micro-tubing and end weights
• Poking tool provided with micro-tubing

• 1

Drill a hole in the side of a plastic garbage can approximately 1 inch from the bottom. The hole should be slightly smaller than the drip irrigation line. Situate the garbage can near the raised bed in an area higher than the bed itself. This will ensure that the water will exit the can through the force of gravity to reach the bed.

• 2

Insert the drip irrigation line into the hole in the garbage can to where the line has approximately 1 inch exposed inside the can. Push the line into the hole firmly by hand. The small area of the hole will help provide a more water-tight seal. The drip irrigation line must be long enough to stretch from the garbage can to the furthest end of the raised bed.

• 3

Screw the female end fitting equipped with a small screen to the exposed drip line inside the garbage can, and then push the fitting until it is flush with the inner side of the can. Squeeze plastic sealant generously around the fitting and the drip line inside and outside the can. Allow the sealant to set according to the product's instructions.

• 4

Stretch the drip irrigation line across the center of the raised bed to the farthest end from the garbage can. Fold the end of the line over and secure it with a hose clamp. Use a screwdriver to tighten the clamp so the water cannot escape from the end of the drip irrigation line.

• 5

Poke holes for the micro-tubing into the drip irrigation line using the tool provided with the micro-tubing. The amount of holes and tubing necessary depends on how many plants are in the raised bed. Each plant requires one line of micro-tubing. Press the ends of the micro-tubing without the end weights into the holes. Stretch the micro-tubing to the base of each plant. The end weights will hold the tubing in place when you water.

• 6

Fill the garbage can with water. Put the lid on the garbage can to prevent evaporation and keep debris from entering the water supply. The drip irrigation system will continuously apply small doses of water to the raised bed. Refill the can with water as needed.

Tips & Warnings

• If a poking tool was not provided with the micro-tubing and end weights, use a sharp knife to poke the necessary holes. If needed, apply plastic sealant around where the micro-tubing is inserted into the holes to achieve a water-tight seal.
