To avoid that the bulb or tuber should become rotten, we must remember to avoid excessively abundant waterings, which keep the soil wet for a long time. We suggest watering these plants only from time to time, but we must remember to wet the soil deeply using 1-2 glasses of water every 1-2 weeks .
Growing they develop a round-shape shrub. Poisonbulb isn't an evergreen; during the summer it assumes a white colouring; the adult species are large in size and reach 1 m in height. The Poisonbulb develops bulbs or tubers.
For a balanced development, it is best to position the The Poisonbulb in a place where it is exposed to at least a few hours of direct sunlight. During the period of vegetative rest, itís possible to take the bulbs or tubers out of the ground; the well cleaned and dried bulbs should be placed in a cool, dry and dark place; to be planted later on during the most indicated time of year.The Poisonbulb usually doesn't have temperature problems during this time of year, because it can bear freezings although not too intense ones.

The spring weather, with a high temperature swing between the day and night hours, and pretty frequent rains, can favour the development of fungus diseases, which should be treated pre-emptively with a systemic fungicide, to use before the gems grow excessively; at the end of the winter we also suggest a wide range insecticide to prevent the attack of aphids and cochineals. We should always remember to do these treatments when there aren't flowerings in the garden.
We advise cultivating these bulbous plants in a soft and light, very well drained, soil.
