There are several compost and manure mixes out there specifically designed to support roses, and many are versatile enough to nurture other shrubs, trees and fruit and veg too. They work well in pots and containers, but you can also use them when planting out roses in beds or using them as a mulch on top of the soil around the base of plants as they grow.
