Does anyone know about how old a sycamore tree has to be before it begins to produce fruit? We planted one in our front yard about four years ago, and have been amazed at how quickly it went from a 3 ft. switch into a 20 ft. tree!
Sycamore maturity
You should be getting seed soon. I have trees slightly older, same size, and they've produced the characteristic golfball-shaped aggregate of seeds already.
After much digging, I finally found this bit of information:
"The earliest commercial seed bearing age is reported to be 25 years; however, well-tended, open-grown trees have produced viable seed at age 6 and abundant seed balls by age 10. Plantation-grown trees of the same age produce seed sparingly, even after thinning."
This totally agrees with what you've experienced and what I have to expect.
Another interesting fact: "It is not unusual for young trees on good sites to average 1 inch in diameter and 6 feet in height growth during each of the first 10 years after planting."
No wonder it's growth seemed so amazing!
Thanks!
