Redford House, a historical home in the Crags area has a
large oak tree in the front garden. The tree is likely to be the same age as
the house and planted as a welcoming feature. Being a mature tree it has begun to
show signs of stress over the past decade, with branch die-back and epicormic
growth towards the interior. For some time since its planting
the tree was watered by a French drain leading from the house and some deterioration has
occurred (see bark picture below right) since use of the drain was discontinued. Charles has
pruned the tree, but has to decide on an alternative method of irrigation.
An inspection of the tree and information about its history has revealed that the paving is about 30 years old; there is a
possibility that periodic application of a herbicide did take place and that
the French drain had been diverted with the modernisation of kitchens and
bathrooms.
“Pruning and the aesthetics of the tree above ground is one
aspect of its recovery,” says Charles, “but the overall health of the tree
depends on the health of its roots.” His and his client’s decision will thus be
how to introduce a deep, possibly slow system of drip watering, to bring the
oak back to its former state of good health.
