DIY capillary watering

The same kind of 10-liter buckets that make up the potato container farm also make  nice capillary watering containers. Two buckets and a small terracotta pot are  all the materials that go into a capillary waterer. How to:

1. Fill the terracotta pot with potting soil.

2. Set the  pot in the middle of one of the buckets.

4. Cut a hole, a couple of centimeters smaller than the circumference of the terracotta pot, in the bottom of the other bucket.

5. Set the bucket into the other, resting on top of the terracotta pot, so the soil is directly under the hole.

6. Fill the top bucket with soil and plant in it.

7. Water around the plant.

8. Fill the water reservoir below the top bucket by watering between the two buckets.

The soil in the terracotta pot will act as a wick, drawing water up to the soil above as needed.

I use them for everything that goes in the greenhouse and thus only have to water once or twice a week, depending on the weather. The tomatoes look happy and fruiting. 🙂



The local pizza place does a great job of  saving 10-liter buckets for me. The buckets would otherwise have gone to the dump. Strange state of things, that we produce buckets for use during a few days and then feed them to the furnace. Anyway, the pizza place sets them aside for me, and I am very happy to use them in the paved areas of my urban garden.  Many of them go to the potato farm, that not only gives us potatoes to eat, but also the opportunity to enjoy their beautiful flowers! Exquisa, Blue Congo and October Blue are flowering at the moment.
