Box is an enigmatic plant in the
garden, surrounded by myth, legend and uncertainty….box blight, box moth, when
to clip; when not to clip; ooops! Derby Day was yesterday, the cut-off
benchmark date for when all Box clipping must be completed, or so they say. I
have been guilty of the same torment and when chatting with a fellow Head
Gardener, who was a bit of a Box expert, quite a few years ago I asked that
very same question…..”when do you cut your Box?”
His answer?.....”Whenever we get the
time”. This made me feel human and realise that I was ok fitting it in and
around the rest of the gardening tasks. For example clipping the individual Box
edged Potager beds when the vegetables have been harvested and new plants are
to go in is good timing. Similarly wading in to clip a Box ball that is
surrounded by blooming Bearded Irises would be folly and only ruin the scene by
the odd stomp of a boot, however careful, wait until the Irises have done their
thing. My policy was to cut from mid-May all the way through to September;
obviously avoiding cutting during extreme heat.
Weather conditions can sway the
decision making process too, as mentioned I wouldn’t recommend clipping Box in
extreme heat, you’d get terrible burn-back of the exposed stems and foliage and
as for wet weather I clip if it needs doing. The other day I clipped a rose
Planted Box parterre in constant drizzle, an uncomfortable process due to the
fact that the foliage stuck to everything; but it needed to be done and my
time-table was tight.
Blight and Moth strike fear in anyone
that has Box and can make having this plant a liability; especially in gardens
where it is the principal feature. The older I get the less inclined I am to
use chemicals, in my own garden going for a more holistic approach with a soil
up philosophy. Whether it be running dogs or plants, good nutrition is the
foundation on which resilient health is built. I have three specimens of Box in
my mixed border and along with everything else I apply mycorrhizal feed to the
beds and soil, even planters too. Alongside this I spray regularly with a
proprietary ‘plant invigorating’ potion that’s basically, after looking on the
label, a mild soap spray, laced with sequestered iron and nitrogen. I spray
once a week and it’s stopped the aphid getting out of hand; also I avoid
ladybirds and if they get the odd drop it’s not going to kill them. The box
gets this spray, to run-off level. I’m not saying these two measures will
prevent and wipe out blight and moth; but good nutrition will help defend and
make any shrub more resistant to attack and the regular soap spray will kill
some of the pest and generally make life awkward for the survivors. Post
clipping I’d also recommend one of the proprietary ‘Bordeaux Mixture’ sprays that
are based on copper and lime, these are nearly organic and usually have a feed
incorporated so it won’t do any harm after clipping to treat the clipped shrubs
with this mild fungicidal tonic. In the end it’s all about finding a system
that works for the ‘operative in the field’.
For me I have a Box clipping season between mid-May and early September
that is dictated to by the day to day management of mixed borders. Good
nutritional health is promoted and pests/diseases lives are made awkward by
routine environmentally friendly sprays.
“the greatest facility that ever
entered the garden was noticing” Davies.J, 1987. Taken from the book The Victorian Kitchen Garden.
I once asked another gardener, that
seemed, to me a bit of an academic, why there were so many different approaches
to gardening; but they all seemed to work whether it be Lunar, bio-dynamic,
organic, ‘conventional’, companion-planting. Their answer was that all of these
systems, when successful, are practised by individuals that believe in the
system and are also constantly observing their ‘crop’, noticing irregularities
and reacting to them by putting in timely measures, routine measures have a
discipline to them. I’m going to leave it there as this is making me out be
some sort of obsessive that stares at their garden; but that might be me being
a late Leo on the cusp of Virgo!
