A simple self-watering salad box can help keep shallow-rooted greens supplied with moisture between regular checks.
The basic idea is to let the growing medium draw water upward from a lower reservoir rather than relying entirely on frequent surface watering. This can be useful for lettuce and other container-grown greens.
1. Use a container with a separate lower water reservoir.
2. Add a wicking section that allows moisture to move into the growing medium.
3. Check the reservoir regularly and refill it when needed.
Self-watering systems still need monitoring, especially during hot weather. The growing medium should stay appropriately moist, not constantly saturated.
