Here's something for your garden, it's the most effective way to water your plants, especially Tomatoes, as they feed close to the surface, but actually get water deeper down. This places it where its needed. You need to get the slotted aggie pipe as shown, the cut it about 45cm for a tomato or shorter for smaller plants. When you dig the hole, you put the pipe in, then plant over it, leaving a little stick out of the ground in case you mulch.
