Arisaema candidissimum

Arisaemas are generally sturdy plants as long as their needs are met. They prefer soil that is rich in humus, light and well-draining. During summer, make sure that the soil doesn't dry out, but during winter, it shouldn't be saturated with water either as the bulb will rot in case of high winter humidity. For planting, partial shade is recommended at the edge of large trees, with westward exposure being ideal. If the soil is heavy, mix 1/3 leaf compost and 1/3 non-chalky sand with your topsoil to a depth and width of 20-25cm (8-10in). When planting the bulb, place it on a small bed of perlite and cover it with your substrate at a depth of 6-8cm (2-3in) to prevent rotting in winter. For potted plants, use a wide terracotta pot that is preferably short, filled with a substrate made of half perlite or vermiculite and leaf compost. Bury the bulbs 6-8cm (2-3in) underground and keep the soil moist but not waterlogged. During winter, store your pot in a frost-free area and maintain a slight coolness. A few drops of water every 15 days will suffice. Resume watering only in early spring, around April, as soon as the bulbs start to emerge.
