I’ve seen those water absorbing crystals that you can add to containers to help them retain moisture. Can I also use these crystals in regular beds of annuals? (I travel a lot and it’s tough to keep them watered on a regular basis).
Many gardeners have discovered that adding moisture-absorbing polymers to their planting mixes reduces watering frequently during the hot summer months…a big help with hanging baskets and outdoor pots.
These crystals look a lot like grains of salt when dry. They absorb many times their weight in water and swell into something that looks like a bite size piece of jello. In the soil, these crystals capture and store water, releasing it as needed to thirsty plants.
Their use need not be restricted only to containers. These polymers can make your summer watering chores much easier…especially if you have a fast-drying, sandy soil type. In general, about six pounds of polymer crystals should be added per 1000 square feet. One application lasts several months.
