How to Store Arisaema Bulbs


Arisaema, or Jack-in-the-pulpit, is a spring flowering bulb prized for its unusual flowers. The upright, trumpet-shaped flower has a single petal that flops over the top of the trumpet. The plant also produces bright red berries and is a reliable self seeder in the garden. Like most spring bulbs, arisaema does best when planted in the fall, though it may take an entire year before it begins blooming. If you receive your bulbs early or must relocate an arisaema bed, storing the bulbs properly until transplant time ensures they remain healthy and viable.

Step 1

Dig up arisaema bulbs approximately six weeks after blooming if the bulbs must be dug and stored because you are moving the bed. Wait until the foliage begins to yellow and die back so the bulbs have a chance to store up the nutrients required for the next spring's growth.

Step 2

Dig around the bulbs to a depth of approximately 6 inches. Slide the spade under the bulb and lift it out of the ground. Don't hit the bulb with the spade while digging.

Step 3

Brush off the excess dirt from the bulbs and inspect them. Dispose of any that show signs of damage, or have soft or shriveled spots, indicating disease.

Step 4

Spread the bulbs out in a single layer on a sheet of newspaper. Place them in a warm, dry room out of direct sunlight to dry.

Step 5

Place the bulbs in a perforated plastic bag filled with dry peat moss. If you are storing recently purchased bulbs, leave them in the mesh sack they came in. Store them in a dry 40 degree F room until ready to plant.

Tips and Warnings

  • Arisaema berries are toxic to humans and pets. Don't store the bulbs for more than two or three months, or they will begin to fade.
