Pruning Deutzia - How to prune
Deutzia and when. Information, advice.
There are several fine species and varieties (cultivars) of Deutzia.
They all have the same pruning requirement as they flower on wood growths
made in the previous growing season (Last year). This is important to
realise, for the current year's growth - such as in late spring
or early summer does NOT bear flowers.
Deutzias can get a bit unkempt in habit if not pruned regularly.
Prune at the right time!
When to Prune Deutzia
All deutzia should be pruned immediately
after the flowers have finished - this will be early - mid - summer. If
you prune them too late after flowering, then they will not have enough
time to produce their new stems - which will be the flowering stems for
the next year.
Pruning in the winter for instance, will remove all the
following summer's flower-bud stems. They do NOT make new flower bud
stems in the following spring.
How to Prune Deutziaa.
is carried out by taking out all of the flowered stems - pruning them
back by about one third of their previous length. So, each stem that has
the faded flowers on, should be cut back, leaving around two thirds of
the stem on the shrub.
Together with this, Deutzias respond to
heavy pruning of around one in three of their stems - right back to - or
near - ground level. This will encourage new basal shoots, which will
soon grow to full length and provide a succession of healthy shoots for
following years. Each year - at pruning time - cut back a further third
of the old stems to ground level. This type of basal pruning will ensure
that you will always have a vigorous shrub that will not get too top
heavy, and it will always be clad with foliage down to or near ground
