This exceptional dry weather has put many trees under stress. I have noticed in particular some Beech and Sycamore are reluctant to open their buds.
On this note, I have never quite understood why the grass under mature trees in parkland or wide verges is either sprayed off or mown to death. It exposes the tree roots to desert like conditions.
With this drought and drying easterly winds it is important the rooting environment is looked after. Why waste money and risk the health of mature trees?
Long grass keeps tree roots moist.
