Plant more raspberries
Raspberry canes have a productive life of eight or nine years, so if you plant new ones before the old ones dwindle, you will achieve continuity. If your old plants are healthy but not growing many new canes, now is the time to propagate from them to start a new row preferably not too close to the old ones. Pick out the strongest of the new canes, and, with a sharp spade, cut halfway down between the new growth and the old and try to lift away the new one with as much soil and root as possible. Raspberries are shallow-rooted plants, so replant at the same depth; they’ll appreciate a trench enriched with lots of organic compost to enrich them and to retain moisture. Cut the new canes back to 18in and don’t let them fruit next year.
Re-tie trained fruit trees
After a season’s use, replace the twine holding your trained fruit trees, even if it still looks fine. Winter’s winds will find out the weakest threads, and you risk damage to trees that have taken years to train. When tying the twine to galvanised wire strung between vine eyes, twist the twine a couple of times around the wire before retying the branch it’ll help to stop the twine slipping along the wire. We find that, on soft-lime-mortar walls, twine tied to galvanised nails is just as easy a way to train the branches; if the mortar is very soft, large fencing staples will hold even better.
Jerusalem artichokes
People either love them or hate them, but Jerusalem artichokes are a useful winter vegetable roasted or in soups. When the tall stalks and their leaves begin to turn yellow, cut them all down to protect the plant from wind damage; the tubers can be dug up when they’re needed. It’s an invasive plant, difficult to get rid of, and we’ve found the best way is to treat it like a potato. In early March, dig and select as many tubers as you need and put them out in a row 1ft apart on the surface of your prepared ground. Now draw the earth up and over the tubers, as if you were hilling potatoes. This produces tubers of excellent size, makes the digging easier and prevents the overgrown muddle usually experienced with artichokes. Try growing a smooth-skinned variety, such as Fuseau.
Tidy herbaceous plants
Ground conditions are usually drier now than in the New Year, so go ahead with the selective cutting down and tidying up of your herbaceous plants. If you prefer to leave the seed heads of your plants after their summer flowering, the different shapes and shades of brown will often still look attractive through the winter, but bear in mind that they can turn into a jumbled mess if there’s heavy snow. Most perennials will continue to be very vigorous if you divide them every few years as each grows and shoots in a different way, it’s a help to know exactly how your individual plants grow. Don’t split the clumps too small before replanting them; always add some leaf mould or compost to the soil when you put them in.
