When you are in the market for a sprinkler that will do a lot of work so you don't have to, consider
Rittenhouse's 30 pound cast iron walking sprinkler
- it has been a top performer for more than 70 years.
If you'd like to reduce your frequency of watering and risk of drought damage, consider adding
Horticultural Grade Terra-Sorb (AKA Super-sorb) to your soil. It absorbs 300 to 400 times its weight in water and slowly releases it. It's non-toxic, non-hazardous to the environment, and compatible with fertilizer. Apply at a rate of 1 pound per 100 square feet for each 2 inches of depth by raking or tilling into the ground 2-4 inches (or mix 1/2 teaspoon into the soil under/around each individual plant).
Terra-Sorb is available at many garden supply stores and online in quantities ranging from 3 ounces to 40 pounds
