Roses: fertilizing

Julie Medbery

Garden roses grow best in slightly sandy soil. They like a pH range between 5.5 and 6.5. Have your soil tested to find out whether the acidity is within this range. The soil test also states the content of soil nutrients. If you need fertilizer, the report recommends how much and what kind to use.

The fertilizer elements most likely to be needed in rose beds are nitrogen (N), phosphorous (P), and potassium (K). If you don't have your soil tested, apply a complete fertilizer. Examples are 5-10-5, 4-8-4 or 4-8-6.
