PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: The best time to plant Iberis sempervirens ‘Masterpiece’ is in spring. Planting at this stage allows the roots to establish before the main flowering season begins.
Autumn: Planting in early autumn is also effective, as it gives Iberis sempervirens ‘Masterpiece’ time to settle before its next growing phase.
Site Selection
Sunlight: Iberis sempervirens ‘Masterpiece’ thrives in full sun but will also tolerate partial shade. For the most prolific flowering, choose a bright location with plenty of direct light.
Soil: Well-drained soil is essential for Iberis sempervirens ‘Masterpiece’. Avoid heavy, waterlogged ground by amending soil with grit or compost to improve drainage and structure.
Planting Instructions
Prepare the Hole: Dig a hole twice the width of the root ball and the same depth.
Soil Preparation: Mix organic matter into the soil to promote fertility and aid drainage.
Planting: Place your Iberis into the hole, ensuring the crown is level with the soil surface. Backfill gently, firming the soil to eliminate air pockets.
Watering After Planting: Water thoroughly after planting to settle the soil. Ensure excess water drains away freely.
Watering Requirements
Growing Season: Keep Iberis sempervirens ‘Masterpiece’ well-watered while it establishes. Once mature, it is drought-tolerant but benefits from watering during extended dry spells.
Dormant Season: Reduce watering significantly in the cooler months, only watering if the soil becomes very dry.
Feeding
Spring: Apply a balanced, slow-release fertiliser in early spring to encourage strong growth and abundant flowers.
Mid-Summer: A light feeding after the first flush of flowers will support prolonged blooming through the season.
Pruning
After Flowering: Lightly trim Iberis sempervirens ‘Masterpiece’ after flowering to encourage fresh growth and maintain a compact shape.
Avoid Harsh Cutting: Do not cut back into old wood, as regrowth can be slow and sparse.
Mulching
Spring: Apply a thin layer of mulch around the base of Iberis sempervirens ‘Masterpiece’ to help retain moisture, regulate soil temperature, and suppress weeds.
Winter: Mulching in cooler months offers extra protection to the roots while maintaining soil structure.
Supporting the Plant
Staking: Iberis sempervirens ‘Masterpiece’ has a naturally compact habit, so staking is not usually necessary. However, in exposed areas, support may help keep stems upright.
