Question
Hi I have obtained catalpa tree seeds and was wondering if there is any specific or proven method for growing these trees from seed? also how would i go about keeping it small enough to pot it for a while?

Answer
Hi Steven,
Thanx for your question.  I have a large, old catalpa growing across the alley from my house and the babies come up readily in the spring.  Some sources say the seed requires some cold stratification, others say it doesn't.  To be on the safe side, plant the seeds under 1 inch of soil in moist, not soggy potting soil and seal the pot inside a plastic bag.  Leave it in the fridge for 6-8 weeks or leave outside for 6-8 weeks during extended temps below 40 F.  The seeds will germinate in the spring if left outdoors or a few weeks after you bring the pot out of the fridge and subject it to 70-75 F temps.  Prick seedlings out after they have a couple sets of true leaves and pot in separate pots.  Grow out until they are about a foot tall and then plant in the desired, full sun, location.  I hope this helps.
Tom
