Once the Rain Bird Irrigation Supplement has finished liquefying what do you do with the quart, the 3″ tube or the square sleeve?
The quart carton is paper and printed in vegetable ink so it can be left in the ground to degrade; this process, depending on climate may take anywhere from 6 months to one year. During the process of degrading the quart will naturally fold into the hole and with natural weather occurrences other soil and leaf litter will fill in the hole completely. If you choose to take the quart carton out of the ground and throw it away simply brush some of the surrounding soil and leaf litter into the hole left behind. The plastic sleeve or tubes are used in situations where the plant requires three or more applications therefore meant for re-use or re-cycling. As with the quart container, when they are removed from the ground, brush some of the surrounding soil and surrounding leaf litter into the hole left by the container. When you are using the tube or the sleeve over an extended period of time, RBIS will leave a protective crust at the bottom near the root zone keeping any air away from roots
