Answer: It sounds as though your ex-boss has had some experience with drainage problems and has given you a supply list for making a curtain drain beneath your planter. If the PVC pipe is perforated, lay it in a trench at the bottom of your planter and cover it with filter screen. Then mix the amendments together and add this mixture to your native soil to help it drain well. The organic amendments will also supply nutrients to the roots of your plants as it continues to decompose. Once you have refilled the planter, dig holes for the plants of your choice. Be sure to water everything in well after planting. Best wishes with your project!
