Best Growing Conditions
Plant rhubarb crowns from autumn to spring in a sunny spot in well drained soil. Prepare the soil well by digging in plenty of well rotted manure and remove all weeds. When planting crowns, ensure the top of the crown sits 3cm below soil level, and space them at 75cm intervals. Keep plants well-watered in their first year and mulch annually with home-made compost or well-rotted manure. Gunnera Manicata has a clumping habit and is hardy to -15C. Although a robust plant, it prefers a sheltered position, is happy in full sun to partial shade and needs a moist, poorly draining soil for optimal growth.
