Hmm that's something I'll keep an eye on, usually just the top dries out a bit between waterings, so I imagine there would still be a bit of moister beneath. I never know how much to let my soil dry out, I know junipers like it dryer than deciduous trees so I tend to keep my elms and maples a little wetter. May be doing it all wrong...longd_au wrote:Is your soil constantly wet?
I sometime see this when my soil is constantly wet for too long. It usually disappear as the weather gets drier.
In the previous growing season the two had identical foliage, and in fact have both receive the same ferts so would this not cancel out the lack of nutrients? If one is showing no signs of discolouration that is..shibui wrote:It is possible that this is just different genes in the 2 plants but more likely a mineral deficiency as tgward has suggested.
