We plant all our above-ground plants in containers with reservoirs.
- Either a Dutch ceramic self-watering system that keeps the soil moist but not wet.
- A Reservoir where the soil touches the water (an overflow drain ensures that the level is not too high)
- Deep dishes under the pots so that the soil touches the water.
We haven't had any plants die on use for over-watering. This includes chillies, tomatoes, strawberries, eggplants, okra, capsicums, blackberries, raspberries, lettuce, and houseplants
