HEATHERS
I have always grown
a few heathers in the garden from way back to apprenticeship days. They were
well used in landscape schemes especially around
rock gardens and in parks, and
there was always an experienced gardener around to show me how to propagate
them from cuttings. Over the years I found new ones to add to my collection.
Forty years
ago I came across Calluna vulgaris Goldsworth Crimson used for
landscaping in Darlington where I worked. It was very popular in the cemeteries
and some housing estate borders not liable to theft or vandalism. The bronze
foliage turns a dazzling golden colour after a few frosts. I took a few
cuttings and still have the plants forty years later as it is still very eye
catching, but to keep the plants from getting too leggy I had to propagate from
cuttings every six to ten years or so. Gold Haze, Beoley Gold and Sunset all
have similar golden foliage. Another must have heather is Calluna vulgaris H E
Beale which is a mass of pale pink flowers at the end of summer. Peter Sparkes
is very similar and just as popular. Then as we get through winter the Erica
carnea varieties come alive with pink, red and white
flowers. Heathers are
popular today as once planted and looked after they soon merge together to form
great ground cover that smother any weeds that try to grow. However for me they
are invaluable as part of my ericaceous border planted together with azaleas,
rhododendrons, camellias and for my very attractive specimen tree the white
stemmed Betula jaquemontia. Another plant that fits into this group is the
dwarf evergreen Pinus mugo, but then you can extend the range with many more
dwarf conifers if space allows. Oriental lilies planted amongst the heathers
will add colour and in summer.

Heathers were very
popular with hill walkers and ramblers as they covered our hills with massive
drifts and when in flower were an
unforgettable picture. Many peoples love of
heathers started as they took home a wee memento of their hill walking
experience. If they subsequently died they would get replaced from the local
garden centre.
Heathers with azaleas |
In their natural
environment heathers grow on open, usually acid, shallow soils but with good
surface drainage. They look great in drifts as big as the garden can afford.
Before planting prepare the ground by selecting an open sunny area and remove
all perennial weeds before digging over and incorporating some leaf mold or
ericaceous compost. Do not use manure and they do not need added fertiliser,
other than some bone meal. Plants which are in pots can be planted at any time
of year, but before planting give them a good soaking and after
planting water
the bed as they do not like dry conditions. Space the plants about a foot apart
or closer if you want an immediate effect.

From spring onwards
they benefit from a mulch of leaf mold or ericaceous compost to help retain
moisture and keep down weeds till they get established.
Heathers need very
little maintenance other than watering in dry weather, keeping weeds down in
early life and trimming back shoots after flowering, but do not prune hard into
old wood as it will not regrow shoots. After ten years or so the plants may get
a bit leggy, so take cuttings and once they grow into a decent sized plant dig
out the old plants and replace them with the young ones.
Heathers can be
propagated by layering or taking cuttings in early summer. Wait until growths
are a
couple of inches long and then take cuttings just over an inch tall but
do not use flowering shoots. Place the cuttings in prepared lime free compost
with added grit or sand burying then half their size and water in well. Place
them in a cool frame but away from direct sunlight. They should root and be
ready to pot up about a year later. Heathers can also be propagated by layering
shoots and covering them with soil and again leave them for a year.

Wee jobs to do this week
At this time of
year, when winter takes its grip and gardening can only be done indoors take a
few moments to draw up a sowing and planting schedule for the year ahead. Check
the sowing dates from last year’s diary and how crops grew and adjust if
necessary. Add in any new crops for trying out this year. I also create an
annual plan of my allotment plot to scale so I can work out how much plants I
can get in. It is also an invaluable tool to plot in a good rotation of crops.
