Wait until the large, fleshy leaves of the tulip plants wither and turn solid yellow before removing the bulbs from the ground.
Insert the tines of a garden fork 8 inches deep into the soil about six inches from the edge of the tulip plants. Pull back on the handle of the garden fork to pry the bulbs up. Set the soil-covered tulip bulbs aside.
Carefully remove the tulip bulbs from the soil. Pull off and discard the withered, yellow leaves from the tops of the bulbs.
Spread out the tulip bulbs on a shaded table or porch to dry out. Leave the bulbs to dry for one hour. Turn the bulbs over and let them dry another hour.
Place the tulip bulbs in a mesh sack or paper bag. Store them away from heat, light and moisture until autumn.
Plant the tulip bulbs in autumn before the first frost. Determine the proper spacing and planting depth for your tulip bulbs according to the species or cultivar. As a rule of thumb, most bulbs should be planted to a depth equal to twice their diameter and spaced one bulb-length apart.
