Don't Let the Cold Freeze Your Plans
Most of our trees are hardy to zone 4, which extends throughout northern MI, including the UP, PA, most of NY, and WI. If you happen to be even farther north than that in the northernmost reaches of our country (Northern MN, NW WI, northern ND or ME, or at high elevations in NY state) you may fall into zone 3 which is colder than most mast producing trees can withstand. Fortunately we have been working the past several years to bring more options for you guys as well.
To check exactly what zone you're in, see our zone map here: Zone Map
We have some great varieties available for even the coldest areas of the country
