If your roses have been thriving for years but suddenly produce lush green growth with few flowers, several factors could be at play. First, check for suckers – vigorous shoots from the rootstock that can overtake the grafted variety. These need to be removed promptly.
Roses need full sun – at least 6-8 hours daily – to produce abundant blooms. Has a nearby tree or hedge grown taller and started shading your plants? Even a slight reduction in light can dramatically reduce flowering.
Roses are heavy feeders. Over time, they deplete soil nutrients, especially if not fertilized regularly. Apply a balanced rose fertilizer in early spring and again after the first flush of blooms. Organic options like compost or well-rotted manure also improve soil structure and nutrient availability.
Addressing these three areas – suckers, sunlight, and soil fertility – will usually restore your roses to their former blooming glory.
