These injection-molded nursery containers have heavy-duty wrap-around rims that are easy to handle and strong enough to pick up heavy plant material. Superior drainage is engineered into both side and bottom drain designs. Squat Containers offer a wide base, which is ideal for shallow rooted plants and produces a better root ball. They also help to conserve water by capturing more during watering. Great for stacking and even greater for windy conditions. NOTE: 1 gallon of  loose  soil will fit in this pot when  compacted . Actual liquid volume is 2.9 quarts.
