1These "remedies" have not been tested by me. I simply recorded them from the internet for my own information. These are recipes to prevent mold and mildew on seedlings, but may help prevent the same in the garden on fully grown plants also.
2I LOVE *Neem Oil* which is all organic & all-natural (follow instructions). Spraying with Neem saved my squashes/melons/tomatoes seedlings (This is from the author of the article although I have heard that Neem oil is very effective from several professional gardeners)
3- Sprinkle ground cinnamon over the surface of the soil & seedlings
4Spray a weak solution of chamomile tea on the seedlings
- Watering or misting with strong chamomile tea
5Spray with Compost Tea-- Compost soaked in water and strained.
6Garlic fungicide: several garlic cloves (mash, pan simmered, cooled & spray)
Garlic spray acts as an insect deterrent also, encouraging insects to move on to more appetizing plants. Unlike many other types of insecticidal garden sprays, garlic can safely be applied to the leaves of plants. Drop the cloves from an entire bulb of garlic into the blender along with two cups of water, puree until finely blended and set it aside for a day. Then, strain out the pulp, mix the garlic liquid with a gallon of water and add it to a sprayer.
7Horseradish Tea: 1/2 cup grated horseradish, soaked 24 hours in 8 ounces of water, strained and use this diluted.
8Apple Cider Vinegar fungicide: 3 Tbs to 1 gallon water
9Baking Soda spray: 1 Tbs Baking Soda, 2.5 Tb oil, liquid soap (NOT anti-bacterial), 1 gallon water
10A weak solution of Milk (2 ounces) to Water (18 ounces) which changes the pH and kills mildew/mold
11Spray a dilute mix of water and hydrogen peroxide 10:1
12No matter what remember: For Seedlings, don't over water (leave sitting saturated), thin out the seedlings, keep them warm (65°+F),AND make sure that there's air-circulation (a small fan works).
It is lack of air movement and too much moisture that supports the mold growth.
