To prune raspberries, remove old canes that have already produced
fruit after they've finished fruiting in the summer or during the dormant
season. For fall-bearing raspberries, you can either cut all canes to the
ground in the dormant season for a single, larger fall crop or prune spent
summer-fruiting canes and leave the new canes that will produce a fall crop. To
replace bushes, monitor them for declining health and fruit production; older
plants or those that become diseased may need to be replaced, but there's no
fixed timeframe for replacement as it depends on the plant's condition.
“The main work that needs to be done to preserve plants is
to create reliable protection for the roots already in November. The roots
prepared in this way will successfully survive the winter and will delight the
next season with a rich harvest of sweet berries.
Proper mulching – saving the roots
The most popular method of protecting the roots is mulching.
Mulch acts as a warm blanket, retaining heat and protecting the roots from
sudden temperature changes. Peat. This is an extremely popular mulching tool.
Peat is laid in a layer of up to 7 cm – it perfectly retains heat and envelops
the roots. Straw. Another effective option is straw. A 10 cm layer should be
poured under the bush, which would reliably hide and protect the roots from
frost.
The main work that needs to be done to preserve plants is to
create reliable protection for the roots already in November. Sawdust. Sawdust
can also be used – small 10–12 cm high layers are poured under the bushes in
piles. In a few years, they will rot and become a natural fertilizer that
enriches the soil.
Additional protection against frost and pests
For additional protection, coniferous branches (spruce
branches) can be used. They are laid on top of the mulch or directly on the
bushes. Coniferous branches not only insulate the roots, but also create a
natural barrier against pests and rodents. In addition to protecting the roots,
it is useful to fertilize raspberries a little in the spring with organic
fertilizers, such as rotted manure or compost. This will help the bushes
recover faster after winter and produce a large harvest. These simple measures
will ensure that raspberries survive even the harshest winter and next year
will delight with abundant, aromatic berries.”
