A Tough Year For Squash



Squash used to be easy. Most years I would have all the zucchini and yellow summer squash I could ever want and more. Last year it was the borer wars. This year with the cool cloudy weather early in the summer, the plants just sat there and produced no fruit. Now that the weather is hot and humid powdery mildew is having a field day. When it is a little cooler at night we have fog. I guess it's a little like athlete's foot for plants. If they never get to really dry off, they are doomed.

I'm getting a few squash now, but the plants are obviously struggling. The newest leaves are still green, but the older the leaves are, the whiter they become. This year the squash are planted far from the rest of the garden. I ponder what to do. Today I picked the squash and did nothing. I guess I could try trimming the diseased leaves off of one plant and see what happens. The butternut vine has only a mild case so far. It might be smart to pull up the vines and call squash season over. I can't decide. For today procrastination works for me.

Bee Balm, the Downside

It's not quite as hot today, but the humidity is unbelievable. I can't tell if there are clouds or if we are just in one. Everything is wet including me.

My bee balm is now showing its Achilles heel. I swear there was no sign of this powdery mildew yesterday. Humidity brings on the powdery mildew and bee balm gets it. We don't use chemicals in the garden. When the plants finish blooming, I will cut them to the ground and clean up all the plant debris.

I guess I should have mentioned this before, but the truth is I get so enthralled with the color, bumblebees, hummingbird moths and butterflies that I totally forget about the downside for this plant. Even with their spotty leaves, the Monardas still look fabulous from a distance!
