Grow Your Own Garlic Rose Fungicide
Garlic Cloves
Did you know you can grow and make your own rose bush fungicide? There are several commercial garlic products such as Garlic GP:Rose Fungicide Qt Concentrate 32 oz but you can also make your own. The acidity of the vinegar discourages disease growth. Place in a quart spray bottle. You can also add 1 teaspoon of baking soda to the mix to also help control black spot and other diseases on roses. Be careful spraying in the heat. Test some leaves before spraying all your plants. Be careful allowing garlic to sit too long and become to concentrated.
The recipe for homemade garlic rose fungicide is to first make a tea or concentrate from the garlic cloves. Take five large cloves of garlic and slice them. Pour two cups of boiling water over the cloves and let sit overnight. Strain the mixture with cheescloth. You can use this garlic concentrate as is, or add one ounce of natural apple cider vinegar to the mix.
When battling black spot and other diseases on roses, don't forget the importance of cultural practices such as keeping the leaves with black spot off the plants and picked up. Mulching helps restrict the spread of fungal spores from the soil onto the plant. Seaweed fertilizer will make the plant strong. A deficiency of potassium makes roses more vulnerable to disease so regularly add sulphate of potash in spring, summer and autumn.

Hi there,
I saw you posting this link on the miskits blog, and thought it looked suitable for my articles on plant pest control, and making a seed propagator.
This link has been added here: Organic Food Plant Pest and Parasite control
And here: How to make a propagator to start your seeds.
Thank you for the idea – I may try stewing some garlic that way, perhaps when I get a big garden (instead of indoor gardening) I can grow my own. Fungi is a particularly annoying problem when growing indoors.
Thanks for the links and the nice comment. I have so many topics to put on this site and so much info gathered, it has given me a new motivation. Thanks. Frugal Gardener
This looks very interesting. I think I’ll try this on my mom’s rose bushes. They’ve been sprouting black spot on their leaves for years now. Would this fungicide work on other plants as well? I have a small tomato plant and a strawberry plant (in seperate pots) that both look like they’ve been infected with some kind of leaf fungus, and I’m looking for effective homemade cures that I can make out of stuff in the house.
