Powdery Mildew and Treatment plan

Last week was filled with a number of things that kept us just one foot in front of the other.  I might get to the point where I will write about some of it.

However the garden is in full swing, making pots of pasta sauce, putting up corn and beans, and lots of zucchini. Eating it fresh, grating it and putting up small bags of it into the freezer for baking at a later point, and I did nine trays of grated dried for use in winter for soups and stews, I like to just put a handful into them. I found this big one hidden (you know it all happens, you think you got them all but nope) which I am going to make a mock apple pie or crumble with it.

Its aug though that means that like most gardens in our zone. Powdery Mildew is starting to show up on the squash plants. It has not hit the truly bad stage where the whole leaf is covered in the grey but its coming! you can see the infected spots on the leaves. Now is the time to try and get it under control as much as you can.

So this issue is common and there are three ways to work on helping your plants.

  •  Remove effected leaves and then either burn them or bag them up and send them off the property. DO NOT COMPOST THEM please.. or you will be adding to the issue 🙂
  • Air flow, this often happens in plants that have lots of big leaves that layer up on each other, taking out those effected leaves will open up the air flow but take a good look at your plant and see if there is a closed off layered area that is not effected yet.. Take out a few leaves to create better air flow in and around the plant itself.
  • Spray those leaves, there are a number of different mixes you can find on the net to spray them with but I am going to keep it basic and simple. Sometimes you just need to change the ph.
  • Mix 1/2tsp of baking soda with one quart of water. Shake it up till well blended and in a spray bottle, spray the leaves top and bottom and down the stems at least once a week or after each bigger rain.

    I had a serious problem with powdery mildew one year, but I think that’s because the squash was in dappled shade. The following year I moved it to a sunny spot and no more PM. I keep the shady spot now for herbs and lettuces. I haven’t had another episode of PM since. I’ll remember the baking powder mix if it happens again though.

    • that’s great that its not a issue where you live, they say locally its tied to our very humid air but its been a issue ever since I moved to the farm. I also do a raw milk/water spray but this year I dried up the milking girls early.
