Garden Newsletter: Squash Vine Borers and Powdery Mildew Prevention

GardensAll Weekly Newsletter May 20, 2018

One of our biggest losses last year was that of our squash crops. We got hit double by squash vine borers and powdery mildew. It was a one-two punch, especially to our summer squash and pumpkins. This year, we are strategizing how to fend off these attackers. And here is a list of our preventative measures.

Squash Vine Borer Prevention

  • Starting the growing year fresh with new straw bales
  • Planting early and using row covers
  • Applying cedar bark mulch along the stems of each vine
  • Checking each plant routinely for signs of eggs and/or actual bore holes
  • Routine spraying with BCT (Dipel)

Powdery Mildew Prevention



General Update

This week, we’ve seen our climbers jump into action. The beans and squash are beginning to take hold of the various trellis and arch panel systems. As you can see from the photos, we are big fans of “growing up”. In small space gardens, that’s a given if you want to grow vining crops.



Finally, we’d like to share our prototype vertical desk system. The third bin of our composting set-up serves as the base. It’s a good height for standing and offers a central view of the garden patch. As such, it’s nice to work outside the home. And… being a gardener, I don’t actually mind standing over the compost! 😀


We welcome any comments and recommendations about dealing with squash pests and the dreaded powdery mildew, or any other gardening topics you may be working with. It’s great to compare notes and discover what really works.

May your garden flourish and your harvests be bountiful!
