Planting & Care Instructions

Where to Plant

Sunlight: This shrub thrives in full sun, requiring at least six hours of direct light daily. While it can handle partial shade, the upright pillar shape stays tighter and you will see many more flowers in a sunny spot.
Soil: Aim for well-drained soil that is rich in organic matter. If you are dealing with heavy clay that stays soggy, plant it in a slight mound to keep the roots above the "bathtub effect" and improve drainage.

Watering Requirements

Water your new Rose of Sharon deeply twice a week during its first full growing season to help the roots dive deep. Mature plants are quite drought-tolerant, but providing extra water during summer dry spells prevents the flower buds from falling off before they have a chance to bloom.

Pruning Tips

Because this variety blooms on new wood, you should do any pruning in late winter or very early spring. A quick trim at this time keeps the narrow columnar shape tidy and stimulates the fresh growth where summer flowers appear. Think of it like a seasonal haircut that ensures the plant puts its energy into making new blossoms rather than maintaining old, woody stems.

Fertilizer Needs

Apply a balanced, slow-release fertilizer in early spring just as the green leaves start to emerge. Avoid using high-nitrogen fertilizers after July because this creates soft, tender growth that cannot toughen up before winter. If the plant is pushed to grow too late in the year, those new stems are much more likely to suffer from winter dieback.
