A SECOND “SPRING”
Pricking Out and Growing On. Whaa?
Make believe it’s spring. That’s what I’m doing this time of year as I drop seeds into minifurrows of potting soil in seedling trays. It’s as if I’m getting ready to plant a garden — and, in fact, I am. The fall garden.
Having a fall garden is like having a whole other garden with no additional space needed. That’s why I’m sowing in seedling trays rather than elbowing my way into the present garden’s valuable real estate.
Today I sowed lettuce, endive, cabbage, kale, and cauliflower seeds. After a week or two of growth in a seedling tray, those seeds should have sprouted and seedlings will be large enough to “prick out” and carefully lift for “growing on” in individual. small pots or cells of multicelled flats of potting soil.

FOR THAT UNWELCOME MEDITERRANEAN LOOK
One Name for Many Diseases
The powdery white coating I notice on leaves of my peony and lilac plants gives them a very Mediterranean look. Not attractive, though, at least to me, because that’s a sign of a disease, appropriately called powdery mildew. If I look around the garden, the disease is probably showing itself, or soon to do so, on a wide variety of plants, including phlox, zinnia, squash, gooseberry, and many more. (This blog post is excerpted from the chapter about plant stresses in my book The Ever Curious Gardener: Using a Little Natural Science for a Much Better Garden.) 
Even though powdery mildew is pretty reliable in showing up each season on certain plants — this is important! — the disease doesn’t necessarily spread from one kind of susceptible plant to the next. Many different fungi are responsible for the disease we collectively call powdery mildew, and each of these fungi have specific plant hosts. Thus, the fungus that causes powdery mildew on lilac (the fungus is Microsphaera alni) cannot cause powdery mildew on rose (caused by the fungus Sphaerotheca pannosa). Read more
WORTH GROWING
Rumors Against Sweet Corn
My fourth and last planting of sweet corn went in a few days ago. I grow sweet corn despite reading years of advice that backyard gardens are too small to make sweet corn worth planting. In the last few decades, that advice has been reinforced by the fact that supersweet corn — which can be more than four times sweeter than heirloom (traditional) sweet corn, and holds that sweetness much longer after harvest — is so readily available at farmstands and markets. I strongly disagree on both counts!
Golden Bantam corn
Backyard gardens are too small? My vegetable beds are three feet wide and about 20 feet long. I plant corn in “hills,” which actually are not at all hilly. In gardening, a “hill” is a station, a location where you grow a clump of plants. Read more
