Note: You want a garden teaming with life. Ecological balance is key to successful organic gardening. Although these sprays are made from non-chemical ingredients, they will kill garden pests as well as beneficials. Spray with care and only when absolutely necessary.
Rhubarb or Tomato or Wormwood Leaf Spray
For control of aphids whiteflies, caterpillars and sucking insects.
Ingredients: Rhubarb/Tomato/or Wormwood leaves, water, natural dish soap.
Directions: Boil water in a large cooking pot, filled halfway. Cut or tear the leaves and add them to the pot of water until it is about ¾ of the way full. Once all the leaves are in the pot, turn off the water and let it steep for 30 minutes. Strain out and compost the leaves. Add 2 TBL of dish soap to the water mixture (dish soap helps the mixture stick to the leaves). Dilute the water to 1 part leaf concentrate: 7 parts water. Use a hand held or backpack sprayer to apply to leaves and stems of plants.
Miracle Marigold Spray
For control of chewing insects including tomato hornworms, grasshoppers, and squash bugs.
Ingredients: Any and all marigold parts, vegetable based soap or castile soap, water.
Directions: Fill a blender or food processor with marigold stems, leaves, and flowers. You can just cut the plant back and use all the parts in your spray. Add 1-2 cups of water, so that you can easily puree it. Blend and let the pulverized mixture set for about 24 hours. Strain through a wire mesh or cheesecloth. Dilute further with 1-2 quarts of water and add 1/4 -1/2 tsp of castile soap (or vegetable based soap, Dr. Bronners for example). Spray directly on insects or plants you want them to keep off of.
