Here at the nursery, the air is heavy with the scent of LIME trees in flower - if you have not experienced this before - it is a rather musty scent - very sweet - produced from a very small yellow flower(SEE PHOTO ON LEFT). Bees adore it, and get quite hooked on it - definitely one of the high points of late summer.
On the down side - a lot of customers are reporting problems with pest and disease on their plants - particularly MILDEW on apples and roses. This is linked in with the weather - predominantly caused by dryness at the roots - so always worth giving your plant a good soak and a mulch - and removing as many of the worst affected leaves and destroying them. Another continual problem is that of the poor old conker trees or HORSE CHESTNUTS - they are now starting to suffer very badly again with that wretched leaf-miner. I have already seen trees that are almost completely defoliated - we were rather hoping that this year would not be so bad - but that does seem to be a false dawn now - although the problem has appeared later than normal. It does not seem to kill the trees - they re-leaf in the spring as normal - but it must weaken them with a reduction in their food source. This can often leave them open to the other more serious BLEEDING CANKER menace - when the trunk oozes black resin - this is often fatal for the tree. I was reading an interesting piece in a magazine that a compound based on a garlic compound is being trialled by the RHS and FORESTRY COMMISION as a prevention for the dreaded canker - and has the side-effect of making the leaves smell of garlic putting off the leaf-miner - can you imagine us all spraying our conker trees with garlic in the future!!??
Until the next time,
