How do self watering systems work

There is an overflow hole, so excess water simply drains away.Press the soil down firmly, but don't compact it, which can interfere with the capillary action.Fixing capillary matting to the tray and reservoir.Once the roots have grown down into the troughs of the planters, the plants will be able to.This is great when you need to keep the leaves dry, like for example with tomato.

If your pot has a central watering tube, make sure you cover the top, so the dirt doesn't fall inside.The top section is where you place your potting mix — do note you'll need to moisten the soil (until it feels spongy, not sodden!) before using it to give your plants a chance to establish a robust root system.Place the pots on the mat.With this type of planter, planters are able to draw from a water reservoir at the base of the planter to water themselves at their own pace.Add about 6 inches of soil.

It relies on capillary action to supply water to your plant roots.In the pictures you can see all my herbs and how the string is in each of their compartments.
