We wanted to build a better jar that would be easy to water yet still have the "look" of a traditional strawberry jar. The result is our nine-pocket Pocket Planter Kit, which features a 4-quart reservoir to ensure consistent, thorough watering -- even during hot weather.
The most important part of the system is the water reservoir, which sits at the bottom of the jar and has a long fill tube the ends at the top of the jar. The fill tube is used to monitor the water level and fill the reservoir. "It's important to keep the reservoir filled for consistent watering," says Sarah Niland, of Gardener's Supply, who helped develop and test the Pocket Planter Kit. "We found that the reservoir holds about a seven-day water supply."
Tips for Success
For plants, we used an everbearing variety called Tristar, which had good flavor and fruited from July 1 to mid-October -- much longer than the typical strawberry season. Each of the planters in our trials yielded an average of over 300 berries each.
