Fertilization Jack in the pulpit
Let’s add some organic fertilizer or humus to the soil, when planting our bulbous plants, in the spring or autumn; later let’s remember to start fertilizing when the flowers are withering, using, every 15-20 days, a specific fertilizer for bulbous plants.

Watering Jack in the pulpitTenere asciutto
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 . 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.

Exposure Jack in the pulpitPosizione mezza ombra
During the period of vegetative rest, it’s 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. Locate this plant in a partially shady place, where it can receive the sunrays during the coolest hours of the day.For a correct development of the plant we suggest avoiding exposure to late freezings; let's grow it in a covered place, locating it outside only in late spring.

Treatments Jack in the pulpit
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.

Soil Jack in the pulpit
We advise cultivating these bulbous plants in a soft and light, very well drained, soil.
