Slim-Spike Threeawn Grass

Jack In The Pulpit is a plant species that needs a specific amount and frequency of watering. Since it grows in moist areas of woodland, the soil should be kept moist but not soggy. During the spring and summer, it should be watered 2 to 3 times a week and the soil should feel slightly damp. During cooler weather, reduce the amount of watering and switch to a monthly schedule. In winter, watering should be minimized with only occasional watering when the soil feels dry. Be sure to avoid overwatering, as this plant does not tolerate soggy soil.

Jack in the Pulpit is a woodland plant native to the Eastern United States and Canada, and requires partial shade in order to thrive. It prefers full shade in hot climates, and should not be exposed to direct sunlight for long periods of time. Plants grown in a dark area, such as a north-facing wall, beneath trees, or on a partially shaded porch, will benefit from 4-5 hours of morning sunlight per day, getting the majority of their light from dappled shade. During the summer months, plants may need supplemental light in order to maintain healthy growth and bloom, but should never be placed in direct sunlight. In brief, Jack in the Pulpit should receive anywhere from 4-5 hours of morning sunlight each day, with the majority of its light exposure coming from dappled shade.

Jack in the Pulpit (Arisaema triphyllum subsp. pusillum) should be pruned during the winter, while it is dormant, cutting off any dead or diseased foliage with sharp, clean shears. Prune off the rhizomes near the soil surface and divide large clumps if necessary. Re-plant divided sections in richer soil and water them regularly until they become established. Pruning should be done with care in order to avoid injuring the shoots or flowers.
