When to plant Masterwort?

Masterwort thrives in partial shade or full sun, though it performs best with some afternoon shade in warmer gardens. Choose a spot with moisture-retentive soil—loam, clay, or peat-based soils are all suitable. The key is ensuring the ground doesn't dry out completely in summer, as astrantia dislikes drought. Prepare the planting area by digging in plenty of organic matter such as well-rotted compost or leaf mould to improve moisture retention and soil structure. This is especially important if your soil is on the lighter side. Work the compost into the top 20–30 cm of soil. Plant masterwort in March, April, or May for spring planting, or in September and October for autumn planting. Both windows work well, though autumn planting gives roots time to establish before the growing season. Dig a hole slightly larger than the root ball, position the plant so the crown sits at soil level, and backfill with soil, firming gently as you go. Space plants 38 cm apart to allow for their mature spread of 30–50 cm. Water thoroughly after planting to settle the soil around the roots and eliminate air pockets. Apply a 5 cm layer of organic mulch such as bark chips or compost around the base, keeping it clear of the crown itself. This helps retain moisture and suppresses weeds. Keep the soil consistently moist for the first few weeks while the plant establishes. Staking is not usually necessary, as masterwort has sturdy stems that reach 40–70 cm and support themselves well.
