Why have white particles appeared around the plants in my garden after a few days of heavy rainfall?

Question

I've recently cleared this plot and planted this garden, so everything that happens is new to me. I can tell you that I only put compost in the soil and mulched it on top. Otherwise no fertilizer, weed killer, etc.

Thanks!

Thanks for the answers so far, but I should clarify that the white fungus or whatever is *on the ground*, not on the plants. It's lying in a circle on the soil around each plant. It does look like a fungus though.

Answer 1

this fungus is called powdery mildue, if left untreated it will kill your plants. if it's just a small amount pluck the veggie,leaf,flower. or you can us a baking soda spray if you want to go organic. this is caused by a dry spell,followed by heavy rain and too much humminity. in the future, plant disease resistant types. also plant your flower,veggies, or plants of choice with a bit more of distance from each other.

1 1/2 tbs baking soda
1 tbs vegetable oil
1 1/2 gallons plus 1 cup warm water
combine baking soda oil and cup of water to mix, then add this mix to the 1 1/2 gallon of water. stir untill blended.por into a hand held sprayer apply immediatley
