Across Colorado, plant tulip bulbs in September or October, at least six weeks before the ground freezes and when the ground temperature has cooled to 55 degrees Fahrenheit. The bulbs need enough time to root in order to ensure they will flower in the spring and so that they will not be pushed out by freezing and thawing.
Tulips bloom in spring, but preparation begins in early to late winter. Tulip bulbs need a minimum of four weeks of chilling before they will bloom. Nurseries often sell pre-chilled bulbs but if not, the process is simple. Start the chilling process in late fall, around late October or early November, in USDA zones 9 and warmer.
The tulip as duly noted in horticultural texts is a perennial flower. This means that a tulip should be expected to return and bloom year after year.

What to do with tulips when they’re done blooming?
Move the pot to a place where it can get sunshine until the Tulip finishes flowering. Once-blooming stops, cut off the flowers to prevent new seeds from forming. Leave the foliage for now. Water the Tulip twice per week, but only when the surface soil is dry. Then water every other week with a balanced fertilizer.
How long does it take for tulip bulbs to flower?
Like most bulbs, tulips require 16 to 18 weeks of cold in order to flower. Cool temperatures stimulate a biochemical response that induces the flower to develop. If the cold period is too short, flowers may emerge but will not be fully developed.

Depending on whether they are early, mid-season, or late tulips, they will bloom at some point between the time your crocuses flower and the time your peonies do the same—usually 4 to 5 weeks after their first shoots appear aboveground. In most areas, plant tulips in mid- to late fall.
Why would my tulips not come up?
Although squirrels and moles are often blamed for damaged flower bulbs, the most common culprit is the field mouse, according to the University of Illinois Extension. Bulbs can be damaged by overly wet conditions, improper bulb storage, bulbs that aren’t viable, poor environmental conditions, and improper tulip leaf care too are a few more ideas to take a look at.
