“Why aren’t my roses growing? My rose bushes do not grow, and I fertilize them once a month, but they don’t grow. Soil is clay-like. They are semi-shade, I have a lot of big trees. They do flower. What else can I do?” Question from April of Dresden, Tennesee
Answer: There are three key factors that are likely keeping your roses from growing, thriving, and flowering to their fullest. They are:
Sunlight: Roses need full sun to grow and flower at their fullest. Six hours per day is the bare minimum they need to really perform well. Eight to twelve hours is even better. The morning sun is preferable to dry leaves early in the day, which dissuades fungal diseases.
Soil: Roses require a fertile, well-drained soil that is slightly acidic (pH 6.5-7) and high in organic matter to perform at their fullest. Amend the soil where they are planted to encourage better root growth and performance. Black Gold Garden Soil and Black Gold Canadian Sphagnum Peat Moss are two excellent amendments to consider
Competition: Tree roots quickly drain water and nutrients from the soil. It is wise to plant roses away from tree roots to avoid competition.
