Roses need full sun, well-draining soil, and regular fertilizing and pruning. Plant roses in the spring, space them 2-3 feet apart, and amend the soil with compost and mulch. Fertilize roses starting in late winter with a balanced fertilizer every 6 weeks. Prune roses in winter to shape the plant and in summer to promote reblooming. Common rose pests include aphids and birds; use neem oil or spray them with water to control pests.
