We live directly on salt water in Maine. Only one growing season so far. Good success with all types of berries. Little to no success with nuts. Best we have ever had with parsnips, sunchokes and carrots. Potatoes not so good but it might be because we were late getting them in the ground. The soil is sandy loam and unusual for this part of Maine. What hasn't done well, at least so far, is sea kale and comfrey. Nettles good, hardy kiwis OK table grapes not so good. The ramps we planted last April came up so we consider that a bit of a success. Sweet corn and winter squash weren't very good. We will see how this season goes. Its still dry and the wind makes it worse.
