Chester County Master Gardeners

Regular Facebook users like me know that there is a lot of junk to sort through every day. But one page that I always look forward to reading is Chester County Master Gardeners. They run lovely photos and amusing plant-identification quizzes, pose tricky diagnosis problems, and offer helpful advice about things like preventing powdery mildew on your phlox (welcome to my life). Yesterday they reminded me that it's potato harvesting time.
