Once the pots are glued together, and the glue is dry, dig a hole in the ground or the pot that you wish to water. I am planting my ollah into a 80l pot which contains an apple tree.

I live on the 8th floor, with a roof terrace that faces due south. Sometimes the pot dries out completely between me watering it in the morning and evening (it's 35degrees celsius in the summer here). The fluctuation between wet and dry puts stress on the tree and that's one of the reasons we've had few apples from it this year. With constant watering from the ollah, the apple tree will hopefully have a happy summer.

In order to sink the ollah you want to dig your hole almost as deep as the pots are tall. Sink the ollah into the hole, and leave about 3cm or 1inch above the soil line. I've also added bark chips to the top of the soil, because it makes the pots look a bit neater.
