How to Make Insecticidal Soap
Got a little too much wildlife in your garden? A homemade insecticidal soap spray should ward off the invaders. It damages insect's cell membranes and is pretty effective against a wide range of pests. The best time to spray is during the early morning or late evening when plants are not in direct sunlight. Saturate both the top and underside of leaves, re-applying as necessary, allowing several days between applications. The soap helps the concoction stick to the leaves (and to the insects themselves).
In case you're wondering, this is Jory's garden where he spends time when he's not making soap or building decks (his second job). Now here's the recipe:
Insecticidal Soap Spray Concentrate
2 C. water
6 hot peppers
12 garlic cloves
1 TBS. castile liquid soap (we recommend our Sunflower)
10 drops lemon, orange, cinnamon, vetiver, or eucalyptus essential oils
Chop water, garlic, and peppers in a blender and let stand overnight. Strain the liquid removing all solid particles. (Whatever you do, don't get the stuff in your eyes or on sensitive areas!) Pour the strained liquid into a plastic bottle and add soap. Store in the refrigerator (or just a cool dark place for several weeks) until needed. Add 2 TBS concentrate per quart of water to a pump sprayer or spray bottle.
Did I mention that your garden will smell wonderful?
