I have a little Indoor vegetable garden that is giving me a bit of fresh produce in the middle of Canada's cold winters. This year, the tomatoes, basil and the parsley were invaded by whiteflies, tiny, aphid-like creatures that make the leaves curl up and eventually die.
I have made a non-toxic spray with neem oil and insecticidal soap. The spray bottle you see in the picture can contain just about half a liter, and the recipe I have been using is:
- half a teaspoon (2.5 ml) of neem oil
- a quarter of a teaspoon ( 0.5 ml) of insecticidal soap
- half a liter (500 ml) of lukewarm water
Put that in the spraybottle, shake and then douse all plants in it. Make sure to spray the underside of all the leaves and open up any curled leaves, that is where those little white buggars like to lay their eggs.
This spray is non toxic and is fine for organic produce, but make sure you rinse off any tomatoes or leaves you harvest, otherwise they will taste bitter.
