ery plant in our garden. Now they’re all dying or wilting. Please help! We have lavender, butter lettuce, jalapenos, mint, basil, cayenne, and rose bushes, as well as echeveria, aloe vera, and sansevieria trifasciata. The succulents are suffering the most. Their leaves are turning black.

Answer 1

I suspect that the aphids caused most of the damage, but any oil based spray can exacerbate issues when sprayed in the sun.

Treatment with oils will need to be done on cloudy days, or in the shade.

Cut out any infected growth, and treat with a fungicide.
