Cultivation Jack in the pulpit
The Jack in the pulpit is medium in size and 50 cm in height; in the summer it assumes a green colouring. These plants aren't evergreens, which means they lose their leaves some months during the year. These plants give origin to a brush with a rounded form. These plants have trunks or roots which store nourishment, originating bulbs or tubers. Fertilize Jack in the pulpit
Bulbous plants use nutritious substances stored from the previous year for their flowering ; this is why usually the soil should be enriched, during planting, with a slow release or organic fertilizer. Later we must fertilize with a specific fertilizer for bulbous plants, every 15-20 days, starting from the moment in which the first flowers are withering. Light Jack in the pulpitPosizione mezza ombra
These plants don't like excessively harsh temperatures, with night-time minimum temperatures below 0°C. during the spring in general they are grown in a covered place, moving them outdoors, or uncovering them, when there isn't any danger of sudden temperature drops. Locate this plant in a partially shady place, where it can take in the solar rays during the coolest hours of the day.If necessary we can extract the bulbs from the ground, during the vegetative rest; after letting them dry we should place them in a cool, dry and dark place. During the most indicated season we can plant them again. Water Jack in the pulpitTenere asciutto
Water sporadically, with 1-2 glasses of water , leaving the soil dry for a few days before watering again; when watering we suggest avoiding excesses, but to wet the substratum well. Let's act every 1-2 weeks . These plants don't need too much water; staying in a soil which is too damp, can easily cause the development of rotten in the bulbs. Pests Jack in the pulpit
Generally during this time of year we suggest a pre-emptive treatment with wide range insecticide and with a systemic fungicide, to prevent the attack from part of the aphids and the development of fungus diseases, often favoured by a mild and damp climate. Mold Jack in the pulpit
Locate in a deep and dissolved soil, with an accentuated drainage.
