Mini Rose Bush Care: Fertilize in early spring, after last & after pruning. Use an even 10-10-10 or 12-12-12 ratio at 1/2 recommended strength every 3 weeks. If outside give more fertilizer: (photosynthesis in direct sunlight). Use high phosphorus fertilizer 2 weeks after 1st leaf buds emerge. Outside: 6 weeks before 1st frost, stop fertilizer & reduce water. If temp below 0, add 1-2" mulch to base. Inside: they need a cool/cold period so they rest. Prune: mid-winter/early spring
