To care for roses, ensure they receive at least six hours of sunlight daily. Water them deeply once a week, allowing the soil to dry slightly between waterings. Mulching around the base helps retain moisture and suppress weeds. Regularly check for pests and diseases, such as aphids or black spot. Prune your roses in early spring to remove dead or weak stems, promoting healthy growth. Fertilize with a balanced rose fertilizer every 4-6 weeks during the growing season to encourage vibrant blooms.
