Trees, Shrubs and Conifers: Please help me save my camellias , 1 by plantreaper

Hello! Newbie here. I have two 12-13 year old camellias that are not doing well. Their leaves are pale green to yellow, and I do not have a single bloom. I don\'t do anything to them -- never have, yet this is the first 12 or so month period they have looked sad and have not bloomed. I am attaching a picture of one, along with its neighbouring plants (a Cala lily and a 12-13 year old lavender plant, plus ground cover). The other camellia is about two feet away from this one. The ground cover (pink flowers) is fairly new. Can that be it? I ask because I have another equally old Camilla in a different spot but with no cover, and it is happy. Do you have any advice? I would like to save rather than replace them. (I admit they have been looking sad for several months, but I have been remiss in tending to them). Thanks in advance!
