- 3. Time, time, time– not on our side. It takes a decade or more for a tree to make its way from propagation, growing to landscape-ready size, to planting in your local neighborhoods. Here – five years from tissue culture plantlet to three-year bare root tree. Two more years in an upstate New York nursery before planting in the Old City neighborhood of Philadelphia.
- 4. Nancy’s points • Ittakes a decade or more to nurture a tree from propagation to landscape-ready size • Tree supply is changing quickly from yesterday’s glut to tomorrow’s severe shortages. • In the recession’s wake, growers can no longer produce trees on speculation. Growing unusual varieties is more risky than ever. • How can propagators know what you will buy, 10 years down the road? How do YOU know what you will need? • In the future, getting what you want will require planning, open communication and creative growing agreements with trusted nursery partners. • Visit nurseries, understand tree production timelines, communicate!
