Self-Watering Wicking Beds

What’s a Wicking Bed?

Originally designed for use in Ethiopia, wicking beds aim to increase food production, while using approximately 50% less water. Think of them as a giant self-watering plant pot. Water is drawn up into the soil via capillary action from a reservoir in the bottom of the wicking bed. Crates, tanks, baths, troughs and drums can all be used to create a wicking bed. Our raised cypress garden beds or instant veggie crates are also the ideal container for wicking projects.

Watering a wicking bed is easy! All you need to do is keep the reservoir topped up occasionally (every week or so in summer). The great news about these gardens, is that they can tolerate dry summer conditions better than normal gardens. There’s no need for a fancy irrigation system, so they are great for renters. They are far more water efficient, and as such, they are also great for those who don’t have time to spend watering their veggie patch every day over summer.

Wicking beds use capillary action to water the plants from a water-tight reservoir in the base of the garden bed.

Are Wicking Beds really that important in Melbourne’s climate?

The global climate is warming and Melbourne has an increased susceptibility to drought. In the near future, effective use of water in the garden is going to become even more important. Because of this, wicking beds are becoming an increasingly popular gardening solution in Melbourne.

Wicking beds are very efficient ways to water your herbs and veggies. The water held in the reservoir can only leave the bed by capillary action up through the soil profile. As it does, most of the moisture is accessed and used by the plants. With standard raised garden beds, much of the irrigation water that you apply usually drains down the sides, or straight out of the bottom. Watering from the top means that a lot of the water, evaporates straight off the soil surface, before it has a chance to soak in to the soil. However, with a wicking bed, almost every drop of water get held in the system and made available to the plants, where they need it most – to their root zone.

Wicking beds are great at maintaining consistent moisture content.  The soil in the garden bed stays moist, without getting too wet or too dry. Contrast this to a drip irrigation system that floods the garden bed every few days, and progressively lets it dry out. Consistency of soil conditions (especially moisture and temperature) is the key to growing great veggies. Wicking beds make growing your own food a breeze!

Our raised cypress garden beds make for perfect wicking beds .

We can install our Raised Cypress Garden Beds as Wicking Beds. After installing your custom made raised garden bed, we create a water proof reservoir in the base. A foam underlay is used to plastic prevent the plastic liner from being damaged. We fill reservoir with scoria or gravel, add a layer of geofabric and then top the planter up with the premium blended soil growing medium.

A wicking bed water outlet, water level indicator and reservoir drainage valve all in one!

The overflow pipe on our wicking beds enables you to easily check the water level of the garden bed. If the level has dropped more than a few centimetres below the surface –then it’s time to top up.

Topping up the wicking bed, with water is easy. Simply connect your garden hose to the tap fitting on the inlet. Turn the hose on and watch the level in the outlet pipe rise. Once the water level reaches the top of the outlet pipe, simply turn off the tap and disconnect the hose.

Over time, nutrients from fertilizers, compost and manures will concentrate in the water reservoir. So it’s a good idea to drain the wicking bed and re-fill it with fresh water. We recommend doing this once or twice per year. Draining the wicking bed is easy. Simply swivel the outlet pipe 90 degrees in an anti-clockwise direction. The water will then empty via gravity flow.

Please Note: We no longer install raised garden beds or wicking beds as a one off project. Our raised garden beds and wicking beds are now only installed as part of larger landscaping projects. Please see our foodscaping page for further details.
