If roses do not get enough water they will wilt, drop leaves, grow smaller leaves or stop blooming. Too much water is indicated by bottom leaves turning limp and yellow and falling off. Deep watering promotes a deep root system. Deep root systems help the rose to survive droughts. Frequent, light watering causes roots to form too near the soil surface, making the plant more susceptible to summer baking.
Soaker hoses provide moisture to the root system while keeping foliage dry.
Avoid getting the leaves wet when watering, especially late in the day. As cold weather sets in, reduce the amount of water, but do not allow roses to completely dry out. Plants need water during dry spells, even during the winter months. Stop fertilizing your roses six weeks before your expected first frost date. Add additional mulch to protect roots and conserve moisture.
