Bulbs For Forcing

Compose your
Greenhouse program

We offer flower bulbs for forcing throughout the season from December 15th until May 20th. We carry a large selection of different varieties for use from early to late in the season. Many of these varieties grown at our own nursery.

Greenhouse Program

Preparation

For optimum growth your bulbs often need temperature treatment. In our large modern storage rooms we are able to give your bulbs the  temperature treatment which is needed to reach the bloom date you are aiming at.

G-Stage

After harvesting, a tulip bulb will develop a new flower inside the bulb. The stage when the new bloom has completely formed in baby size inside the bulb is called the G-stage. We take samples of our tulip lots, and we research by microscope to set the date of G-stage for each bulb lot. Starting from the date of G-stage we can calculate what can be  the earliest cooling date for this bulb lot.

Pre-cooling

For flower bulbs needed for early forcing we offer the service of pre-cooling in our storage rooms. Depending on your location and circumstances in your greenhouse we can decide with you what is the optimum temperature for storing and shipping your bulbs.
