[brane_damaj]

How many years does a silver maple need to grow before it is mature enough to drop seeds?

[Q.E.D]

The won’t produce seeds until they are at least eleven years old, according to this:

Seed ripening and dispersal over the range of the species begins in April and ends in June. The number of seed-filled fruits per kilogram ranges from 1,980 to 7,050 (900 to 3,200/lb), with an average of 3,920 (1,780/lb), making these the largest seeds of any maple species in the United States (38). Dissemination is mainly by wind and occasionally by water. The minimum seed-bearing age of trees is 11 years.
