When to plant Hemp Agrimony?

Hemp agrimony thrives in moist, fertile ground and is particularly well suited to bog gardens, pond margins, and damp borders. Choose a position in full sun or partial shade; flowering will be most prolific in sunnier spots, but the plant tolerates a few hours of shade without difficulty. It grows happily in loam, clay, or peat-based soils, provided moisture levels remain consistently high. Plant container-grown specimens in March, April, September, or October. Avoid planting during summer or in frosty conditions. Dig a hole slightly larger than the root ball and work in plenty of organic matter—garden compost or well-rotted manure—to improve moisture retention, especially if your soil is on the lighter side. Set the plant at the same depth it sat in its pot, firm the soil gently around the roots, and water thoroughly. Space plants 60 cm apart to allow for their mature spread of 40–80 cm. Hemp agrimony forms upright clumps that can reach 80–150 cm tall, so position it towards the middle or back of a border where it won't shade smaller neighbours. If planting near a pond or stream, keep the crown just above the waterline; the roots will seek out moisture below. After planting, water generously and apply a 5 cm layer of organic mulch around the base, keeping it clear of the stems. This conserves moisture and suppresses weeds while the plant establishes. In exposed sites, young plants may benefit from a temporary cane for support until the root system anchors them firmly. Water regularly through the first growing season, especially during dry spells, to encourage strong root development.
