Planting Time
The tulip bulbs are going to be planted. Most important: plant them twice as deep as the bulb is high. They have no roots at this stage.
Making Roots
The roots start growing out of the base. They establish themselves in the dirt and take nourishment out of the dirt, the mother bulbs get ready for winter.
Cooling Period
Now starts the rest period. In order for the bulbs to bloom in the spring, they need weeks of at least 5 c. or 40 f. Frost at this time does not harm the bulbs.
Growing Period
The bulbs begin to change as the starch, or carbohydrates in them turns to sugar. As this occurs, the leaves and flower gradually push up-wards out of the bulb.
Blooming Time
The tulips are in bloom-they receive their nourishment from the roots-only the brown skin of the bulb remains as all of the energy has gone to the bloom.
Regeneration
After the blooming period-the blooms are cut and the leaves are left on the plant. The new daughter-bulbs will be using the food values of the leaves to grow.
Multiplying
Up to five small bulbs can be expected to grow out of the mother bulb. They form their roots slowly, and develop their blooms and leaves within the bulb, for next year's plant.
