Step by step: plant bugleweed
Bugleweed thrives in partial shade, full shade, or even full sun, making it a versatile groundcover for awkward spots where other plants struggle. It tolerates a wide range of conditions but performs best in loam or clay soil that holds moisture without becoming waterlogged. Before planting, clear the area of weeds and dig over the soil to a spade's depth, working in a little garden compost or well-rotted manure if your soil is particularly poor or free-draining. Plant bugleweed in March, April, September, or October when the soil is workable and temperatures are mild. Space plants 30 cm apart to allow them to spread and knit together into a dense mat within a season or two. Dig a hole slightly larger than the root ball, set each plant at the same depth it was growing in its pot, and firm the soil gently around the roots. Water thoroughly after planting to settle the soil and eliminate air pockets. In spring plantings, keep an eye on moisture levels during dry spells in the first few weeks. Autumn-planted bugleweed benefits from the natural rainfall and establishes well before winter. Apply a 3–5 cm layer of mulch around (but not touching) the crowns to suppress weeds and retain moisture while the plants settle in. Bugleweed spreads by stolons—horizontal stems that root as they go—so it will fill gaps quickly once established. Avoid planting it too close to delicate perennials, as it can be vigorous and may smother less robust neighbours.
