Steamy sun rays

Question

I live in North Carolina, and lately it has 95 degrees and over. Is the steaming sun the reason why my marigolds and perennials are dying?

Answer 1

They usually do well in high temperatures I do see what looks like clay soils and this will be the cause of slow growth here. They will grow much faster in a soil with more texture. Try adding organic material or a little compost before planting to help out.
