Tips for Appling Natural Pesticides for Vegetables

Apply the chosen pesticide on top of the vegetable plant leaves as well as underneath–you should not overdo it, excess can cause damage.

Most of them are very effective as a weekly treatment. Excessive use can affect vegetation as well as kill the beneficial creepers you want to encourage in your garden (earthworms, bees, ladybugs, etc.). If you are not able to see results with a 7-day treatment, you can bump it up to 5 but watch very carefully to make sure plants can handle it without being damaged.

Avoid treating plants during very hot sunny weather and do so later in the day to reduce the risk of burning.

If it looks like rain, you can delay until the weather is clear since any rain will wash away the new pesticide application. If it has recently rained, then you need to wait till greenery is dry before applying to prevent the mix from being diluted with rain.

When you are trying a new solution, better to test on just a couple of leaves first which means apply then watch how they react after two to three days if no signs of damage then you can proceed with spraying.
