Thanks, clo. Lots to think about in that little message.
re: You need to open the pits of peaches & plums to find the seed.
So crack 'em with a nutcracker before planting them?
re: "I think the seeds need to be dried before planting."
That sounds odd. Why?
re: "Then they will need constant watering."
New Hampshire, remember? Constant watering, not a problem. If I remember right, New Hampshire has about 125 days with precipitation each year.
When I was young, my parents bought about 40 pounds of nectarines at a flea market. We dumped the pits in the back yard - near where we used to burn trash before Sacratomato banned the practice.
A year or so later, trees were coming up all over the place. When we moved, a friend dug up about twenty of the 2-foot and smaller saplings and stuck them in his Marysville back yard. They were awesome producers within a few years - though they were assaulted by the blight a decade later and wiped out.
Sooo, I don't think the pits necessarily NEED to be dried or cracked. That might help, but neither is essential. Not with nectarines, anyway. Heck, we didn't even PLANT those things. They just grew.
And Sacramento gets relatively little precipitation... entire Summers, sometimes, with zilch rain.
BTW, I am *definitely* going to reintroduce the American chestnut tree on the land. The tree used to dominate the forests of the easter U.S. Now it's practically extinct in tree form, though it still grows as a shrub.
I know where to get blight resistant trees. It might be 50 years before they're full sized, but I should live to at least have some good size chestnut trees on my land.
