Self-Watering Planter Tips:
Watering Tip: Watering times may vary depending on the environment. The reservoirs usually need to be refilled every 1-2 weeks. In some cases the reservoirs may need more frequent watering if you are in an extremely hot, arid climate and less frequent if you are in a moist, damp, cooler climate. Remember that even if the reservoir is empty, the soil can still be very moist even if the top looks dry. Be careful not to over water.
Pest Tip: Since you will have sitting water in the reservoir, it is possible it will attract mosquitos. To prevent mosquitos from entering your reservoir, cover the fill tube with a waterproof cork or tape.
If you have edible plants growing in your container garden, pour a couple drops of cooking oil into the water to break the surface tension which discourages mosquitos from laying their eggs.
If you don't have edible plants in your containers, mosquito dunks are very effective and recommended as it will kill mosquito larva for up to 30 days.
Soil Tip: Hooks & Lattice recommends a lightweight, fibrous soil for use with self-watering reservoirs. This will assist the "capillary action" that draws water to the roots and help the distribution of moisture throughout the root zone. Avoid soil will too much sand or clay. Soilless potting mixtures with perlite, peat moss, and coco coir work well.
