Planting spring bulbs indoors is a method of forcing the flowers to bloom. Using care and planning, bulbs will bloom from November to April. According to the University of Missouri, any spring-type bulb can be grown indoors. The most popular bulbs for indoor growing are hyacinth, daffodils and tulips. There are many varieties available within these species of flowers. Most all bulbs are planted indoors during the first part of October.
Place an inch of pea gravel in the bottom of the shallow pot. The pea gravel allows for drainage from the soil mixture of any excess moisture. Bulbs left in standing water with soil will rot.
Mix equal amounts of garden soil, sand and peat moss. Set the soil mixture to the side.
Arrange the bulbs in the pot on top of the pea gravel. Place the bulbs close together. As an example, six tulip, three hyacinth or six daffodil bulbs may be placed in a single 6-inch diameter pot. Keep all flower varieties to their own 6-inch pot.
Add the soil mix to the pot. Keep the tips of the tulip and large hyacinth bulbs exposed. Daffodils will prefer if they are set higher in the pot, so at least half of the bulb is exposed. Smaller bulbs such as crocus or grape hyacinth will need to be covered with an inch of the soil medium. Fill the pot to within 1/4 inch of the top rim.
Add water until it drips from the drain holes.
Set the bulbs in a well lit area out of direct sunlight. The temperature should be kept below 65 degrees F.
Bring the flowers to warmer areas of the home when the flower buds begin to open. Keep the plants from heat sources such as direct sunlight or furnace registers. Extend the flower's life by placing the pot in a cooler area at night and bringing it back out during the day so all can enjoy.
