A wicking bed is a self-watering system and this wicking bed design is also very attractive and stylish.  In the wicking garden bed, the water sits below the pot and then wicked upward in the upper soil of the container. 

In this article, we will discuss the step-by-step process of building a wicking bed and if you are interested in building a wicking bed we hope that this article will be very helpful for you. You can also modify the design of your wicking bed.

Galvanized Steel Raised Bed.

1. Place the raised bed in the desired location because when the wicking bed is filled with soil then it is immovable.

2. To determine level place spirit level at crossways and lengthways and ensure spirit level at different angles.

Because a wicking bed needs to be leveled properly as it holds water and if the wicking bed is not leveled properly then water will drain out on one side and be too dry on the other side.  So level wicking the bed properly if one side is high then dig some soil and if the bed is low and needs raising then lift the bed and add some soil and level properly.

3. Above 20cm from the4 ground drill a hole in one side of the raised bed. And then lay down a pond liner inside the raised bed and fit it properly.

4. Firstly install a 20mm threaded pipe outlet and then cut a hole in the hole so that it fits in the pond liner to fit in the hole. Then install a rubber washing fitting against the pond liner and a water-tight seal is formed.

5. For preparing water inlet drill 10mm(⅜)  holes all around in the last 30cm, in 50mm wide PVC pipe.

For efficient watering extend the length of PVC pipe high enough above so that you can water your plants easily without any trouble. Foe A water inlet you can use an L shape inlet. Take a horizontal cross-section of three to four quarters of the bed and drilled it all around with holes of 10-12mm. Join two pipes with elbow joints and just push-fit the pieces as a friction fit is sufficient and necessary.

6. Then lay down a thin layer of coarse scoria it will act as a protective layer of pond liner so that it can’t be damaged by PVC pipe inlet.

7. Clamp the raised bed with the pond liner with the help of small spring or screw clamps so that the pond liner keeps in place while the raised bed is filled with material. 

8. Fill the garden bed with coarse scoria to the height that is level with an overflow outlet.

But make sure that your coarse coria level will be fairly leveled and even. Then lay down a geotextile fiber or shade cloth over the scoria layer and wrap it well around the inlet pipe so that no soil will be entered in the scoria layer.

9. Cover the scoria layer with the help of two geotextile fiber layers and extend it up 15cm above the pond liner.

The geotextile fiber must be tucked in all around the sides where scoria meets raised bed so that your raised bed can work properly.  For making sure no soil will be entered in the scoria layer you can place vertically extended sections between the scoria layer and pond liner.

10. Check that the scoria layer is leveled properly if any high sports are present level them.

Low spots can be leveled by pulling around the spot are by pressing around the sides. If the scoria level is too uneven then lift the geotextile fiber and level it properly after leveling put geotextile fiber in its place. Check one more scoria layer is leveled properly or not.

11. After making sure the scoria layer is leveled properly fill the raised bed with potting soil(sterile garden loam, sand, peat moss, compost, manure, coco peat mixture perfect for growing plants). And make sure that pond liner is placed against the walls of raised bed as you fill it with soil.

12. Trim out excess pond liner with the help of scissors by leaving 3cm of the pond liner in the soil.

Your wicking bed is ready to use and for planting plants. For the best experience firstly wet soil the soil evenly and water it repeatedly until water starts running into the scoria layer.  After wetting soil evenly fill the water reservoir with an inlet pipe and fill water until the water begins to flow out by overflow pipe.  Plants up your wicking bed and for conserving moisture mulch soil.
