Hi Everyone,

These sedums (angelina) were planted in 2019 or 2020 and had been the most robust plants in my yard; they need little water in a full-sun spot and alternate between beautiful bright yellow and red from summer to winter.

They had been healthy until about 2 weeks ago---there are several brown spots, and some are dying. Is it due to lack of water (but some of them are still flourishing), or is it because I did not remove the foliage (from trees from other part of the yard) and the decomposition of the leaves causing problems to the sedum?

Thanks so much!
