When to plant: Plant UNRRA Mollis Hybrid Azalea at any time during the growing season when there is no danger of frost.
Water with at least an inch of water per week. The soil should be kept moist to a depth of 18 inches. Water again when the top few inches of soil dries out. Always water deeply, as frequent, shallow watering encourages a shallow root system and an unhealthy plant.
Fertilize this plant with phosphorus during the first year. Phosphorus encourages root growth. Once established, fertilize with flowering shrub and tree fertilizer in the spring, before new growth appears. If a soil test shows low or missing nutrients, use a nutrient-specific fertilizer instead of an all-purpose fertilizer. If you use organic fertilizer such as fish emulsion, be sure to follow the instructions on the package, as different brands have different ingredients and strengths.
UNRRA Mollis Hybrid Azalea is a low-maintenance shrub that produces green foliage and fragrant, showy, single flowers in shades of orange and red. The flowers are long lasting.
Cut flowers early in the morning before the dew dries. Use a sharp knife or gardening shears to make an angled cut on the stem. Immediately immerse in cool water. Add a teaspoon of sugar to the vase water to provide the blooms with nutrients. Change the water every other day, adding a teaspoon of sugar and making a fresh, angled stem cut at each water change.
Prune UNRRA Mollis Hybrid Azalea in the spring and throughout the growing season for dead and decaying plant matter. This plant has growth buds. If you pinch the terminal buds (at the end of each branch) off, the lateral buds will be forced to bloom.
Propagate with cuttings. Cut a six-inch stem tip and dip it in rooting powder. Plant the stem tip in amended soil and water well.
