The Poisonbulb is a pretty delicate plant, which fears minimum temperatures below 15įC; during late spring it can be cultivated outdoors. 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.Plant which need at least a few hours a day of solar light.
The Poisonbulb develops bulbs or tubers. Poisonbulb isn't an evergreen; during the summer it assumes a white colouring; the adult species are medium in size and reach 60 cm in height. Growing they develop a round-shape shrub.
Letís add some organic fertilizer or humus to the soil, when planting our bulbous plants, in the spring or autumn; later letís remember to start fertilizing when the flowers are withering, using, every 15-20 days, a specific fertilizer for bulbous plants.
We suggest watering these plants with 1-2 glasses of water only when the soil is perfectly dry, generally it needs to be watered about every 1-2 weeks . Let's avoid to exceed. 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.
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.
Seeing the quite contained development itís possible to grow these plants in a container. The indications given in this article are related to a medium size plant.
