No, you’re not lost on an arts and crafts blog. These polyacrylamide polymer crystals can absorb 400 times their weight in water, swelling up to a jelly-like consistency and looking like watery ice, and photo pool member Poekie knows how to capture the beauty of that process. But these crystals can also save your lawn and your pocketbook.
Those of you with lawns, especially if you’re in the southwest, are probably dreading the summer water bills — or you’ve abandoned your yard to the summer scorch and the fire ants. These polymer crystals’ll catch and hold the water that hits your yard, slowly releasing the water as everything dries out.
About four to five pounds will treat 1,000 sq. ft. of lawn or garden, and you’ll want to work it in, spreading it after a lawn aeration or tilling it into your garden. Many sites offer advice on how to use the crystals. The great news: they last for years — though estimates vary, five years is conservative — and they’re biodegradable.
The crystals are sold under many names and brands, but in general you’ll pay $9 to $14 for a single pound — bulk prices are less if you can find them.
