All the old canes of fall-fruiting raspberries like ‘Autumn Bliss’ and ‘Allgold’ can be cut down to ground level in fall and the region around them weeded, taking particular attention to remove perennial weeds. Burn or otherwise discard of the canes as they may be harbouring pests and diseases.
Next month the soil around the roots can be given a dressing of general purpose fertiliser such as chicken or sheep manure pellets or Crowmore to give spring growth a boost and this should be followed up with a generous mulch of well-rotted garden compost or manure to help support humidity during the summer months and to suppress weeds. Cut autumn raspberry canes down to ground level in December and use a mulch around the roots.
Mint dies back in the winter and comes to life again in the spring, so looks pretty forlorn at this time of year. It is usually grown in containers to prevent the creeping stems from taking over the plot, but the roots are so vigorous that they soon fill the compost and plants then become starved and lack vigour.
Lift clumps of mint from the garden or empty them from their containers now and split the clump into small sections, each with some healthy roots. Some can be replanted back into the container in fresh compost and covered with a cloche or placed in a cold frame or cold greenhouse where they will begin to shoot earlier than plants outside come the spring, giving you some early shoots. Of course, if placed in a heated greenhouse they will grow away even more quickly.
Any plants that you don’t need can be potted and given to friends and family, but do warn them about the plant’s habit of taking over if allowed to do so!
PLANT EARLY PEAS
Peas can be sown direct into well-prepared soil in winter, providing your plot is free-draining and sunny. You are going to need a cloche to cover the rows until the worst of the winter weather has passed. However, if you have a frost-free greenhouse or polytunnel you could start some early harvests now or into deep pots for example Rootrainers.
PREPARE THE GROUND FOR ASPARAGUS
You are able to get a head start by selecting a bright, well-drained site and digging in lots of well-rotted organic matter for example manure or garden compost. Perennial weeds are among the largest difficulties with long-term crops such as this (asparagus should prune well for at least 15 years), so anything you are adding to the land must be weed-free and when making your preparations make sure you remove any weed roots you encounter.
If your soil is very weedy – perhaps you have recently reclaimed a neglected allotment or converted part of the garden for vegetables – it is best to cover the ground for a season with thick ground cover fabric or black polythene to kill the weeds prior to planting.
