Home Care for Sub-Irrigated/ Self-Watering Planters

25 Feb

IMG_3034Thanks to all who came to the workshop last night. I am sharing some tips we use at Benji’s school for PTA plantings…But this is one philosophy or approach, not the only one. Ansley and other gardeners may have different takes on how to proceed — keep your eye on the comments section!

1. (At home) Remove and fill the bottom reservoir cup with about 2-3 inches of water. For one time only, water plant from the top to allow soil and wick to settle. Wick should dangle into liquid to allow soil to “suck up” the water and “self water” the plant.

2. Place in full sun or sunny windowsill.  aclk

3. Add water to bottom cup every 2-3 days. It is OK to spritz soil from the top, but “watering” should be done via the reservoir in the bottom of the planter.

4.  If you need to add soil, use organic potting soil.

5. Depending what you planted, be ready to transplant a little early, because, according to the Farmer’s Almanac, Spring may come early.  The 2016 prediction for NYC’s last frost is April 1st. (Last Spring Frost prediction tagged as having 50% probability).
