Harvest tulip seeds after the flower has died.
Wait for the green bulge, the tulip seed pod, under the dead flower, to turn brown.
Open the tulip seed pod and remove the seeds after the seed pod is completely dry and has formed cracks.
Place your tulip seeds in a Ziploc plastic bag to allow them to germinate.
Put moist vermiculite (a mineral that expands when heat is applied) into the bag with the seeds in it.
Place the bag in your refrigerator, as this will prevent the seed from losing moisture.
Make sure that the seed germinates for 90 days before planting.
Place the tulip seeds 1/4-inch deep in a pot of soil, at least 1/2 inch away from each other to prevent crowding.
Keep the soil damp and at room temperature. The seeds will germinate faster when kept in the right conditions.
Use warm water when they need moisture added to them. Determine when the seeds need watering by checking to see if the soil is dry. If it is dry, they need more fluids.
