Newly planted roses need consistent moisture, either from rainfall or your hose. Aim for a deep watering at least once a week until you see new growth from the base or stems — that’s your sign the plant is established.
Once established, you can reduce frequency to encourage deeper roots, greater drought tolerance, and improved winter hardiness.
-
Yellowing leaves without black spots can signal too much water, or that the roots are sitting in wet soil. Roses do not like having their roots too wet, too long.
-
Water deeply and infrequently. Moisture should reach 12–18 inches into the soil. Shallow watering encourages shallow roots. Shallow roots reduce drought tolerance and winter hardiness.
-
Watch your plants. Drooping leaves indicate the need for water.
-
Adapt to conditions. Soil type, temperature, and rainfall all influence how often to water. In hot or arid climates, a weekly deep watering can be enough, while in cooler or heavier soils, less is needed.
- Potted or container roses need to be monitored closely as they dry out faster and may need watering more frequently.
