All pumpkins and squash will develop powdery mildew symptoms if weather conditions favor the fungus. Resistant or tolerant varieties develop symptoms more slowly and maintain leaf coverage later in the season. For more information about controlling powdery mildew, see the New England Vegetable Management Guide, found online at http://www.nevegetable.org/.

 All varieties should be trialed on a small scale to determine whether they are suitable for your growing conditions, and markets.

Leyland Cypress

“Cypress foliage is very flammable.  It is sticky and aromatic, two signs that is contains volatile waxes, oils and other substances that burn hot.  Flammability may not be an issue in a situation where the trees are isolated from other plants and flammable material (like fences), but consider that in recent years Leyland cypress plantings have contributed to damaging fires in southern Oregon.”
