Cork oaks: assessing winter’s damage

Winter has been long and fickle this year. Mainly, I’d say, it’s been drier and colder than usual, with fewer storms. But between the cold periods there have been unseasonably warm spells (up to 20C); between the dry spells there have been huge rain storms; and between the calm spells there have been some ferocious and freezing winds. Tipyn o bopeth (a bit of everything) really and quite challenging in the garden.

The young cork oaks (which are now two and three years old) have mainly suffered from the tortrix moth caterpillars, as per usual.

But in addition, they have also been being eaten by some kind of leaf miner…

and the younger trees have suffered a little from the lack of moisture and freezing winds – showing in the orangey-bronzey tints you can see  in the picture above, alongside the dull buff colour where the leaf miners have stripped the living cells.

However, I’m happy to say, that they all seem to have come through OK and have plenty of new buds for this year’s growth. Hopefully winter will soon go away and they can put on some strong new growth through the summer.
