WINTER PROPAGATION
Mid January can be a
quiet time in the garden.
Most plants will be dormant and it is still a bit
early to sow this year’s seeds. With a bit of luck the dry sunny days at the
beginning of the month were perfect to catch up with the winter digging, and at
this point the winter has been relatively mild. This has helped the snowdrops
and aconites to spring
into action. The snowdrops started to flower in mid
December and now the aconites are opening up on sunny days and adding to the
show.

However we still
like to keep active so now is a good time to think about propagation of a whole
range of plants.

Some plants can be
propagated in winter by lifting up suckers growing away from the parent plant.
Both raspberries and saskatoons grow easily from suckers but make sure they
have plenty of roots to get them started. Strawberries can also be propagated
at this time using runners that have grown away from the parent plant and
lifting them with a good ball of soil. Traditionally strawberries are planted
in rows three feet apart spacing the plants a foot apart, but, as often happens
if there are plenty spare runners then plant a lot closer in the row so the
first crops will have more fruit.
Blackberries can be
tip layered by bending the ends of long shoots down to the ground and pegging
them in firmly. They should be rooted by mid spring. They can also be
propagated by using the tips as cuttings, putting them in pots of free draining
compost and keeping them in a cold frame or unheated greenhouse over winter.

Layering is also
very successful with the evergreen Japanese azaleas, winter jasmine, heathers
and hydrangea petiolaris. It usually helps if you scrape some of the bark off
and peg the shoots down into the soil covering an inch or so with top soil.
They should be well rooted by next winter.
Berries of
chokeberry, blueberry and saskatoons saved from the summer crops had the seeds
removed and placed in between layers of damp kitchen roll and placed in the
fridge for six weeks, checking on them to keep them moist and free from
botrytis. They were then sown in seed compost, but need a period of cold
weather before they will germinate, so keep them outdoors to get exposure to
winter weather.
Wee jobs to do this week
