I’m a novice gardener. Back in august I planted a camellia (Mary Williams) that I was given in a large container. It’s in a North West facing spot and was doing ok until all the recent rain. When I potted it up, I don’t think I added enough grit to the soil, and used a mix of ericaceous and normal compost which maybe wasn’t acidic enough on balance. Some of the leaves have started wilting and drying. I suspect that the roots are waterlogged.
How can I correct this? If I take it out of the pot to change the soil mix and add in some more grit I’m nervous about damaging the roots and disturbing the buds
