is there any tree that can bear fruit in the frosty winter in the east coast New Jersey?

Answer 1

No... The blossoms would freeze at the first frost and the fruit starts from the blossom so you wouldn't have any fruit

Answer 2

I can't speak empirically on this subject, I'm from Michigan. However, on consulting my handy-dandy USDA hardiness zone map, you appear to be in balmy zone 7, as compared to my very fridged zone 5. The only reason I can think of on why you wouldn't be able to grow, just about any, fruit tree and have it produce fruit, is an unseasonably late frost.

I think you would have absolutely no difficulty with apples and pears.

Again, along the lines of zone 7 vs 5, you should be able to grow plums, peaches, cherry's and nectarines. You probably could grow apricots too! If you are very near the ocean ( you can taste salt spray) there definitely could be complications, but I am almost certain that the trees themselves would grow for you.

If you just can't get a tree to produce for you, try raspberry's, at least you'll have some fresh produce!

I hope that this helps
Good luck -

Not that I know of, but there is a Witch Hazel bush that flowers in Febuary, in Massachusetts . So anything is possible. I have never dealt with any State University people from New Jersey so I do not know the level of Horticulture programscthat they might have.,
I do deal with the University of CONNETTICUT, and they have a great Hort. Program. You could start there after you have exhausted local sourses!

You could call the county cooperative extension office for your county and ask for either the county arborist or a master gardener. They work a hot-line to answer just your sort of question and can also help with choices or alternatives for your area. Good luck
