White mildew

Question

What is the best way to apply NaHCO3 to squash plants to stop white mildew?

Answer 1

Prior to using your sodium bicarbonate (i.e. baking soda), water your plants thoroughly. Also, test it on a small section of plant to make sure that it doesn't suffer any bad reaction.

Add about 1 tbsp. baking soda to 4 cups of water and 1/2 tsp. of liquid soap (don't use any with bleach). Mix in a spray bottle and mist the infected plants, including the undersides of leaves. Repeat 7-10 days. Spray in the morning or evening.
