Raspberries
All your raspberries should be dormant by now.
However, if ours are anything to go by there are probably still
some green leaves about. Now is the time to prune out old canes
and tie in the new growth that arose during the summer. When
removing old canes use a good secateurs and cut right back to
soil level leaving as small a stump as possible. You can remove
some new canes also so as to leave the healthiest ones spaced at
about 4” (10 cm) apart. Tie in these canes firmly to their
supports.
Strawberries
Strawberry plants are now dormant.
Little is now required although the mild autumn has meant that
weeds continued to grow, and these may need attention.
When the leaves have died off and gone brown (which is still
some time away), they can be removed to help prevent the spread
of diseases into next seasons crop.
Apples
Winter is pruning time. There are a number of
principles that you can consider when pruning. Remove any
suckers (shoots coming up from the ground level). These will
compete with your tree. Remove branches hanging on the ground.
Remove diseased branches or diseased parts of branches. Try to
get your tree into a pyramidal (or Christmas tree) shape. Do not
take off too many branches – this will just encourage lots of
new shoots next year. Try to assess how many fruit buds you have
– these are the fat rounded buds. A 2 metre tall tree (6 feet
tall) only needs perhaps 100. If there is an abundance of fruit
buds then prune some off. If they seem scarce then preserve the
branches on which you see them.
Plums
At
this time of year you can assess whether your plum trees have
Silver Leaf disease. Those that do will have many little
toadstools (up to 1 inch in size (2.5cm)) growing from the trunk
or main branches. If the tree is badly infected it should be
removed to prevent spread to other trees, although if you only
have one tree it can be left in place in the hope that it may
recover.
Do not prune plum trees at this time of year, as it facilitates
spread of silver-leaf. Wait until May, when the disease is not
active.
Last
year's Winter garden advice
In our previous
newsletter I mentioned the two apple growers days that were
going to
be held. These have now taken place, and it looks like they will
bear some fruit.
The most interesting new apple varieties that were mentioned
were some disease-resistant types which, when planted in a
garden would need no spraying at all.
So, to add to the list of good garden apples like Discovery,
Katy, Bramley’s Seedling and James Grieve are some new types
like Santana, Topas, Retina, Alkmene (Early or Red Windsor),
Pinova and Delcoro.
While not all these new types are immediately available to
gardeners, over the next two or three years they should become
more widely available. Keep an eye out for these easy-to-grow
apples.
