Do self-watering products like gels work?
Hydrogels, or self-watering crystals, are additives that absorb water and then slowly release it. However, Gillman has tested them with hundreds of plants and not seen any great benefit. “Don’t expect more than a small boost to moisture,” he says. Instead, lay down an inch of compost followed by two inches of bark or wood chips to hold in water. Other options include setting up a simple soaker hose or drip irrigation system connected to a timer. Amy Stewart is the author of four books on the natural world.
