Old Bulbs, New Tricks

Each fall you must plant NEW BULBS for your JOURNEY NORTH garden. However, there are countless ways you can use your old bulbs the following fall.

Growing Experiments
After investigating their own new bulbs, have students dig up the old bulbs. The old bulbs, if they were properly watered and let die back naturally over the summer will be in perfect shape for experimental projects. Tulips generally can grow and flower with satisfaction for up to 5 years.
Before digging them up, p
redict what they'll look like, thendig and inspect them, weigh them, measure them, compare them with new bulbs, and finally replant them. How are old bulbs different from new ones? Have students predict how each old bulb will grow the next spring, based on its unique characteristics.

New Trick: Forcing the Issue


Only a Few Will Do!

Keep in mind, you only need a few NEW bulbs each year. If your budget doesn't allow for new bulbs for all students, just purchase a half dozen or so.

Designate the new bulbs as your "JOURNEY NORTH" tulips, and ONLY report to Journey North when the new bulbs emerge and bloom.(But tell us about your "EXPERIMENTAL" garden using old bulbs in the Comments of your report.) Don't forget, the planting instructions are an important part of the large Journey North tulip study, so follow them closely!
