|What can you tell me about the climate and soil required for loganberries, dewberries and boysenberries?|
|Loganberries and boysenberries are both dewberries, which are reliably hardy only to zone 6. The vines need a long growing season to harden off the wood for winter. The variety "Lucretia" is the hardiest and may survive winters in zones 4 or 5. Some northern gardeners have success with covering their plants with a foot or so of shredded leaves or straw during the winter.
Dewberries need rich, loose deeply dug soil. A good addition of manure prior to planting is beneficial.
