natural Pesticides

DIY Pesticides for your Garden

So let’s start by saying applying pesticides that are designed to make bug’s stomachs explode are bad for humans too. Since you, your kids and your pets live and play in the garden or eat the veggies and fruit that come out of it, let’s not ingest anything that will give you cancer. Now that we are agreed, let’s keep those bugs at bay the natural way!

Awesome and Easy Pesticide

One tablespoon of castile soap in a spray bottle (about 750 ml or 25 oz.) will work for most things. For an added punch, add 10 drops of any citrus oil as this also helps it to stick to the plants better.

Got stubborn borers, Japanese Beetles, or leafhoppers? Add chilli powder (cayenne pepper works too) and a bunch of crushed garlic to the recipe above and you are good to go!

Java is where it’s at

When you’ve brewed your morning cuppa, don’t discard your grounds. Instead, sprinkle your left over coffee grounds around your veggies to fend off mosquitoes, ants, slugs and maggots. They are also a great fertilizer for plants that like more acidic soil like rhododendrons and azaleas.

Fungal Diseases?

No problem! Just mix together 1 tablespoon of baking soda and 1/2 tablespoon of olive oil in 2 liters (2 quarts) of warm water. Spray on affected areas and your plants will be fungus free in no time.

Chrysanthemum tea

Did you get a bunch of flowers? Save the mums and make this really great tea that paralyses bugs. Mums have a chemical compound called pyrethrum that is really effective on most insects. Just boil a handful of flowers in a liter (1 quart) of water for 20 minutes. When cool, pour the tea over your plants.

    For fungal problems, a mix of nonfat milk and water, 1:1, works beautifully, and doesn’t add salts to the soil like the baking soda mixture does.

    I love the simplicity of these solutions! Anyone that isn’t aware of the versatility of castile soaps doesn’t know what they are missing. Also, I like that I don’t need to run to the store for everything else – just hit up the kitchen!
