Diatomaceous earth could also be used around the plants. Even though it is not harmful to humans and possibly animals it should not be inhaled while sprinkling it...hard on the lungs.
Mits mentioned Tums..that is good, I also use epsom salts in the hole usually when I first start a plant.
This yr , I sprayed around the roots with epsom salt water, i have 2 old pepper trees from last yr(hubby kept in his office as he gets sun thru the window all afternoon). The leaves r stunted n yellow..lot of flowers but they dry up. The epsom salts didnt work on these . Last wk i did the milk thing as Mits bhaiya suggested
.n i used the dawn plus water for the insect on my pepper leaves
well, thanks to u guys, i am now ‘educated’ for next summer!! Saving all the tips here
