Maintenance Good color can be enjoyed all summer with good watering, fertilization and grooming practices. Once established, plants should receive supplemental irrigation as needed. Daily watering is not required, nor recommended because too frequent irrigation can lead to disease problems. Most beds will need watering only two to three times per week in the absence of sufficient rainfall. Irrigate during the early morning hours, rather than evening, and apply enough to slowly and thoroughly soak the root zone.
Fertilization is important to keep plants growing vigorously.
If a slow release product is not used at planting, light supplemental applications of liquid or granular fertilizer can be made every 4 to 6 weeks. Groom plants by removing old flowers before they have time to produce seed. This practice keeps plants producing more blossoms instead of expending their energy on seed production. I can't seem to find anything in my gardening references. Confederate rose is a hibiscus.
