Ha! didn't realise we could start a Gardener's Corner on baexpats...
I have a camellia in a large pot on my balcony -- in the past few weeks it's really started to take off but a lot of the leaves are yellowing -- I believe it's a lack of iron, so i bought some the other week and have done the treatment around the base etc... but I'm wondering, is part of the problem the tap water here? i didn't think so, i've had it for a couple of years and this is the first time I've had the problem so not sure if it's just lack of nutrients in the soil, overwatering, or maybe the mineral balance in the tap water? like I say, it's in a container, and been there for a couple of years, so maybe I need to replant with some new compost?
