The following styles of planter all have a water reservoir underneath the planting area:
- Mayne Tall Planters that have a removable tray
- Patio Planters
- Window Boxes
With the water reservoir, capillary action allows water in the reservoir to soak upward keeping the soil and plant roots moist creating a "self-watering" effect.
Regular watering is required for the first few weeks giving the root system time to develop. Once the roots have grown down into the troughs of the planters, the plants will be able to pull moisture from the reservoir. With this system, you will find the potting mix stays moist longer than traditional planters. To avoid over-saturation an overflow hole allows excess water to drain out.
Although "self-watering" containers still need to be watered, they need to be watered less frequently than your typical planter.
How often you need to water will depend on a number of factors including, climate, sun exposure, rain exposure, etc. As a general rule, we recommend watering once per week once your plants are established. Many will likely find they will need to water less frequently than this. If the potting mix begins feeling dry simply continue to add water until excess begins coming out of the overflow drain hole. This will ensure the potting mix is well soaked and the reservoir completely filled. You will get into a routine with your plants after a couple of weeks.
