Make an insect spray for my outdoor plants
Hi Das, I've had good luck with this one but you will have to reapply anything over time https://www.mom4real.com/homemade-bug-spray-plants/
Here is an easy one I found on Hometalk: https://www.hometalk.com/42157187/easy-homemade-fungicide-spray-for-plants-two-ingredients
There are many ways to make an effective insect spray. Hope this helps!
Try this mix: one part liquid soap to 40 parts water. Spray on and then leave for about 10-15 minutes. Hose off. Do not apply in the hot sun or it may burn the leaves. You can add a drop of cooking oil if you wish to make it stick to the leaves and stems.
