| how do you get rid of black spots on girard rainbow shrubs leaves or are they suppose to have black spots? |
| Fungal leaf spot diseases and mildew can be troublesome on stressed-out plants. Removing older canes will dramatically reduce fungal problems and will also rejuvenate the plant. Prune out affected stems and leaves to promote good air circulation and remember they prefer acid, moist, well-drained, organic soil and should be planted in partial to full shade. |
