Andrew Tokely's Gardening Tips for December!

Although the festive season is just around the corner, there are still a few jobs in the garden that need attending in readiness for the New Year ahead.

  1. During the summer months, climbing Wisteria’s have grown lots, so now in December is  the ideal time to tie in the new shoots to build up the framework of branches. First, prune back each side shoot so it is just 2-3 buds long, then cut out any unwanted straggly growth back to the main stems. Once this is done you won't need to prune these again until next summer. These vigorous plants will also benefit from having a winter mulch of old compost or well-rotted manure placed around the base of their stems.

  2. If the weather is too cold or wet to do any jobs outside, then there are plenty of jobs to do in the warmth of the greenhouse or shed to prepare for next year. A clean of all the sowing equipment is required. Wash pots and seed with soapy water, so they are clean and ready for use early next year. Propagators and benches can also be washed down so they are clean from any pests or fungal diseases that may be hiding in those tiny crevices. This will give us all a clean start to the year ahead.
  3. Remember during very cold weather to look after the birds regularly. Leave our bird feed and top up the birdbath so they have some fresh water to drink. If you encourage the birds into your garden at this time of year, hopefully they will also return next spring to nest and feed on some of the aphids and other pests that can cause us gardener’s problems.

  4. On Christmas day, I will be busy sowing my Large Onions. Christmas or Boxing Day is the traditional time for sowing this vegetable, plus it will give me a good excuse for getting out of the washing up. I sow the variety Globo, as these will grow into whoppers over 1-2lb in weight. Onion Seeds need sowing onto the surface of moist seed sowing compost, and then they should be lightly covered with fine grade vermiculite. Once sown, place in a heated propagator set at 20C (70F). Germination usually takes 10-14 days.

  5. Bush Roses are best pruned in March, however during wet summers, they can grow quite quickly. This growth would be best reduced down by about half during December. This will stop the tall growth from being caught by any strong winds, as this may cause wind rock, or may even uproot or loosen your plants. Once the tops have been reduced, leave them alone until you need to prune your Roses again next March as usual.
  6. December has arrived and this is the ideal month for pruning Blackcurrants. Now that all the leaves have fallen off the plants it makes it easier to see what you are doing. When pruning Blackcurrants you should cut out as much old wood as possible to leave just young growth, that is less than 3 years old. The younger shoots will grow more vigorously and in turn will produce more fruit. The older wood is easily recognised because it is much darker in colour than the younger shoots, and often the bark is a lot rougher. Always try to prune down to a healthy new bud as close to the base of the plant as you can. This will help encourage new shoots to grow from the base. Once pruned give the blackcurrant plants a generous mulch of well-rotted manure or garden compost.

  7. Check your appples and pears in storage this winter for signs of damage or rot. Removing this will stop fungal spores spreading to the rest of your fruit.
  8. When the weather is cool and dry, take advantage of these nice days to dig the vegetable plot. If this job is done from now until the New Year you will have a neat and tidy plot ready for the new season. I always dig in plenty of well-rotted manure or mushroom compost to help add some nutrients and structure to the soil. I find digging pleasurable as well as a great way of keeping fit and it helps burn off any of those calories that I may have put on over the festive period.

  9. If you have some large clumps of Rhubarb, why not cut a piece off and leave it lying on the top of the ground this month to get frosted. This cold period will spur the growth buds into developing sooner. Leave the Rhubarb laying there for several weeks until it has been frosted several times, then pot it up and move it into a warm (Not hot) greenhouse or shed. This will then start to produce some tender sticks of Rhubarb for you to enjoy next spring.

  10. It always surprises me how much colour and scent there is in the garden at this time of year. Rather than leave this scent outdoors why not cut a few stems of winter flowering Honeysuckle, Viburnum and Mahonia as they show colour and place them in a vase of water indoors. Then as the buds open they will fill your rooms with their colour and fragrance.
