Cultivation Details
Gaultheria x wisleyensis is a fairly hardy plant, able to tolerate temperatures down to about -20°c[1]. Prefers a cool moist but not boggy humus rich soil in shade or semi-shade[2, 3]. A peat and moisture loving species, it requires a lime-free soil[2]. Plants in this genus are notably resistant to honey fungus[3].
Propagation
The seed requires a period of cold stratification. Pre-chill for 4 - 10 weeks and then surface sow in a lime-free compost in a shady part of the greenhouse and keep the compost moist[4]. The seed usually germinates well, usually within 1 - 2 months at 20°c, but the seedlings are liable to damp off. It is important to water them with care and to ensure that they get plenty of ventilation. Watering them with a garlic infusion can also help to prevent damping of[PFAF]. Prick out the seedlings into individual pots when they are about 25mm tall and grow them on in light shade in the greenhouse for at least their first winter[PFAF]. Plant them out in late spring or early summer. The seedlings are susceptible to spring frosts so might need some protection for their first few years outdoors. The leaves remain very small for the first few years[2]. This is a hybrid species, producing fertile seed, but will not breed true. Cuttings of half-ripe wood 3 - 6cm long, mid summer in a frame in a shady position. They form roots in late summer or spring[4]. A good percentage usually take. Division in spring when new growth is about 7cm tall. Larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-21. <temperate.theferns.info/plant/Gaultheria+%C3%97%C2%A0wisleyensis>
