Organic garden spray can keep your garden free from pests without the use of harmful chemicals. You can even make a homemade spray using common kitchen ingredients like onions, garlic, and hot peppers. Here's how to make your own organic garden spray:
1. Choose a recipe according to your pest-repelling needs. There are many recipes for organic garden sprays available; each has a specific purpose. For example, one calls for dicing an onion and then soaking it in water overnight. This will protect your plants against aphids. It is safe to use on food, because the onion smell and flavor will not be absorbed by the plant. Others call for hot pepper sauce and chopped garlic cloves; be sure to investigate whether such ingredients will impart a smell or taste on your plants before using them on fruits, vegetables, or herbs. A simple soap and water spray can be used to kill many bugs on your plants, and it will not make the plants taste funny.
2. Mix the spray. Mix the spray according to the instructions. Depending on the ingredients used, you may need to strain it before use, to prevent it from clogging the nozzle of the spray bottle. Many organic garden sprays involve using a blender to mix the ingredients. When the mixture is ready, pour into a spray bottle. Make sure to clearly label the bottle, because many organic garden sprays can look just like water.
3. Spray your plants. When spraying your plants, make sure to be more thorough than simply misting the tops of the leaves. Most garden pests live on the undersides of the leaves, so be sure to get all surfaces of the plant. You may also want to spray some of the ground around the plants.
4. Spray again, as needed. Most sprays should be used daily, although some will be effective if used every few days or even every week. Unlike most conventional pesticides, these homemade sprays will biodegrade quickly. Reapply often, especially after it has rained. Most types of homemade garden sprays will last for a month or two before you'll need to mix another batch. Depending on the ingredients, the spray may need to be refrigerated between uses.
Homemade garden sprays often rely on spicy foods or those with strong odors to repel garden pests. These organic remedies are much safer than commercial pesticides, especially if you plan to eat anything from your garden. These alternative sprays will not cause any harm for pets, bees, or birds that may find themselves in your garden. Plus, they are often much less expensive than commercially available pest repellents. Another organic way to repel pests in your garden is to plant herbs with pest-repellent properties.
