The Q&A Archives: Blue Rug Juniper, ground cover

Question: I have Blue Rug Juniper ground cover on slopes, do you need to mulch around each plant? I know that it said to mulch to keep the grass out until they have a chance to spread, just didn't know if it meant right around the plant. Mine are planted the hot sun most of the day and on a medium slop. I'v had a time with them. They want to turn yellow then die out. I'v dug them up and replanted them, because some had sunk down to much below the grown surface. It's just been a job to keep them green, also, I do keeep them watered. The only thing I could think is that maybe I had to much mulch around them. Your expertise in this matter would be greatly appreciated. Thank You, Glenda Martin

Answer: Glenda,

Deep mulch around the plant can contribute to rots and other such problems. You can put a light layer of mulch around the plants but you need not really put it right up against the stems. The sinking indicates maybe the soil was worked too deeply in the planting hole and is now settling. Water enough to maintain moisture but as infrequently as possible to avoid encouraging foliage diseases. Drip irrigation is best but not always an option.

Thanks for the question. Please stop in again soon!
