Planting & Care Instructions

Where to Plant

Sunlight: For the best flower production and the tightest arching habit, plant in full sun (at least 6 hours of direct light). While it handles part shade, you will notice fewer of those signature fragrant blooms and a slightly more open growth pattern.
Soil: This shrub prefers well-drained soil rich in organic matter but is famously adaptable to different textures. If you have heavy clay, plant it in a slight mound to keep the roots from sitting in water, or mix in some compost to improve drainage.

Watering Requirements

During the first year, water your Mockorange twice a week to ensure the root system anchors deeply into the soil. Once established, it is quite drought-tolerant, though consistent moisture during the heat of summer prevents the leaves from wilting and ensures a better bloom set for the following year. Inconsistent watering during dry spells can lead to smaller flowers and premature leaf drop.

Pruning Tips

Because Illuminati Arch® blooms on old wood, you should only prune immediately after the spring flowers have faded. Think of this like a post-show haircut; cutting too late in the year removes the buds already forming for next spring. Focus on thinning out the oldest, thickest stems at the ground level every few years to encourage vigorous new growth and maintain that elegant arching shape.

Fertilizer Needs

Apply a balanced, slow-release fertilizer in early spring just as the new growth begins to emerge. Avoid using high-nitrogen fertilizers late in the summer, as this stimulates soft new growth that won't have time to harden off before the first frost. This late-season growth is easily damaged by winter cold, which can kill the very tips where your spring flowers would have appeared.
