| Extension growth of
young ash and sycamore grown in farm forestry in
Co. Sligo is strongly affected by exposure. Ash is
susceptible to terminal bud death resulting in
much forking,
thus the species requires regular pruning. It is
suggested that: a. ash and sycamore should not
be planted in mixtures,
b. shelter (shelterbelts and/or nurse crops)
should be provided,
c. ash requires regular pruning,
d. seed source of planting material needs to
be altered, and
e. thinning regimes of ash and sycamore are
species specific.
It is stressed that quality crops of ash and
sycamore can only be achieved by careful
silviculture (combination of shelter, weed
control, formative pruning and thinning) in
conjunction with the use of adequate planting
material.
