If you spend a good deal of time away from home, are going on holiday or are just a little absent minded, the chances are that your beautiful house plants could miss out on regular watering. The ideal solution is to use self-watering pots but these can be expensive. They are a simple device however and can be made easily with cheap readily available materials.

Things You'll Need

  • Tape measure
  • Plastic food container
  • Cutting device
  • Acrylic string

Measure the base of your plant pot and make a note of this measurement, adding 1/4 inch.

Adjust your circular cutter to the noted measurement and cut a hole in the center of the lid of a plastic food container. Make sure that this hole is just a little wider than the base of the plant pot so that the plant pot sits securely in the hole but will be suspended above the surface of the water.

Cut acrylic string to a length of about 6 inches. It should be long enough that when in place there will be enough to allow about 2 inches to go into the base of the plant pot with the other end touching the bottom of the food container.

Remove the plant including the soil from its pot, being very careful not to damage the root system. Push 2 inches of the string through one of the holes in the bottom of the pot and return the plant to the pot.

Fill the food container with water, taking care not to fill so much that the base of the plant pot will be submerged.

Place the plant pot in the food container with the string dangling in the water.

Monitor the moisture of the soil for a few days. If it becomes too dry, double the thickness of the string. If it becomes to moist, replace the string with a thinner one or add perlite to your growing medium.
