Homemade Fruit Tree Spray
. . . that can be used throughout the growing season even if you don’t yet have a problem with insects or fungi.
It’s easier to keep your plants disease-free than to try to cure them once they’re infected, and this is where a homemade fruit tree spray program using natural ingredients found in your cupboard can play a big part in keeping your trees (especially fruit trees) fungi and insect free. As a matter of fact, you might consider having a spraying routine and using natural or homemade fruit tree spray for your fruit trees from early spring right on through the summer months.
Please be advised. I am told that the “Homemade Fruit Tree Spray” as outlined in this article will spell the eventual death of a peach tree in the Southern States. The molasses and vinegar will encourage bacteria growth and parasitic insects (which Murphy’s Soap will not kill). The genus Coleoptera (beetles) thrive on this spray. Boring beetles eventually will kill the tree. Please those of you living in the hot Southern States, do not to use this spray on peach trees.
The norm is to treat every bearing fruit tree with at least one spraying of a mixture of garden sulfur and horticultural oil early in the spring BEFORE LEAFING OCCURS in order to kill any overwintering cocoons.
However, I have found the natural homemade fruit tree spray outlined below can work just as well. . . even better. It is safe to use, easy to make, and does not have the possibility of burning the trunk of the tree by mixing incorrectly as might be done with sulfur and oil mixture. (Unfortunately I have done so a few times when I first started to spray my fruit trees)
Whether you use the sulfur/oil mixture or this mixture for your spring spraying of fruit trees, throughout the summer you might want to continue using the natural homemade fruit tree spray recipe on a regular basis in order to keep insects and fungi away from your fruit trees. (The idea is to subtly change the smell and feel of the tree and fruit so that the insects do not recognize it and at the same time feed your tree.)
My favorite natural homemade fruit tree spray is the one suggested by horticulturist and organic gardener Howard Garrett. He says his Wash-Away-Fungi spray packs a punch because it contains four fungus-fighting ingredients, and he is right.
I added the Murphy Soap because it helps the
homemade fruit tree spray stick to the leaves
and this soap is pure vegetable oil soap (no synthetics).

Here in Ontario, it can be bought at Canadian Tire or Home Hardware.
Homemade Fruit Tree Spray: The Wash-Away-Fungi Recipe
In order to create this “Wash-Away-Fungi” recipe, you will need the following:
1-2 cups of compost tea
(Optional if you don’t have any compost which is completely finished)
(If you are spraying edible plants or fruit, do not use tea made from manure compost)
1 tablespoon liquid seaweed (found in plant nurseries)
1 tablespoon apple cider vinegar
1 tablespoon of Murphy soap
1 gallon water
Backpack or pump sprayer
Special Explanations About The Ingredients:
The compost tea, the seaweed, and the molasses not only fight fungal disease in the garden, but all three feed the plant through the leaves (called foliar feeding) especially if you are spraying really early in the morning when the leaf pores are still open.
You needn’t worry about the molasses attracting bugs. I was until I saw how the plants absorb the molasses instantly. Boom it’s gone! The fruit trees just love it!
The acidity of the vinegar helps kill black spot on roses, powdery mildew, brown patch, and other nasty fungi.
Mixing The Ingredients:
It’s easy to do. Just measure and pour the ingredients in the sprayer and mix well.
Hint: I found that if I premix the tablespoon of molasses in a 1/2 cup of very hot water and then pour the whole thing into the sprayer, the molasses mixes better with the rest of the ingredients. I found out the hard way that cold water and molasses don’t mix so well!
If you want your spray to have even more “umph”, add 1 to 1 1/2 tablespoons of baking soda/ potassium bicarbonate or 1/4 cup garlic tea.
To make garlic tea, liquefy 3 bulbs of garlic in a blender and strain out the solids. Pour the garlic juice into a 1-gallon container and fill with water. Shake the garlic juice well before using.
When And How To Do Your Spraying:
1. When spraying this homemade fruit tree spray, do not blast away or you will damage the leaves. Rather, lightly mist the top and the underside of all the leaves and be sure not to drip vinegar on the soil or grass if that’s where you are putting your mixture together.
Vinegar is very acidic, so when putting your mixture together, find a spot where if you spill anything it won’t matter or it can be easily cleaned up. If you’re not steady when you measure your right amount of vinegar for the mixture, the vinegar can kill the grass it falls on or hurt any roots just under the top layer of soil. So be careful. (We used to kill dandelions by spraying pure vinegar on them in the middle of the day when the sun was very hot. The grass around the dandelions would sort of get scorched even though we tried to avoid spraying the grass — a task not easy to do.)
2. Do your spraying VERY EARLY IN THE MORNING for two reasons:
a) If you spray when there’s little or no wind, you avoid back spraying yourself or spraying your neighbor’s plants. Yes, you must get up early in the morning to get your spraying done before the wind starts blowing.
(Certain people may argue that usually the wind dies down after 6 pm; however, your trees have just been through a hot day so need time to recuperate. Also the spray must dry before nightfall, and many times at night the humidity is high.)
b) By spraying early in the morning, you avoid damaging the leaves because you are allowing time for the spray to dry before the sun gets hot.
Once you have finished your spraying, CLEAN YOUR SPRAYER THOROUGHLY with hot water and soap.
If you have some kind of a spraying program using natural sprays such as this homemade fruit tree spray that both feed and protect your fruit trees, you should have a lot better luck at keeping your trees healthy and fungus free.
