Gardening Calendar December 2020




This months GardenAdvice gardening calendar focuses creating spring colour for next season.
  • Dividing plants Another seasonal job is dividing your plants such as Day lilies and other perennial plants such as hostas. If you are not sure what you can or cannot divide just drop us a line at the GardenAdvice free advice servicehttps://gardenadvice.co.uk/advisor/freeadvice/index.html
  • Cold soil is going to be a real problem when it comes to spring vegetable sowing with all the rain we are having wet cold soil is going to be a real pain when it comes to sowing the first vegetable seeds. The constant rain will have cooled the soil down to such a degree that it will take more spring sunshine to get seeds germinating. Four methods to overcome this are as follow
    * sow your seeds as far as possible indoors to product small plants not always possible with plants such as carrots but with lettuce and other such salad crop the cold conditions can be over come. Sow in trays and prick out into small pots.
    * Use cloches and black plastic - Both cloches and laying black plastics on the growing a few weeks before sowing will have the effect of warming the soil for better germination and stronger plants.
    * Spent mushroom compost - adding spent mushroom compost to your soil has the effect of helping to dry up the soil in the case of creating a seed bed making sowing easier and warms up the soil.
    * light forking - with all the rain the soil structure will have taken a beating a light forking will help get air into the soil and help restore the soils structure.

    Mild wet winter - If the weather continues to be wet and mild then the next problem that will be facing gardeners is fungal and disease damage to your plants especially the softer leaved plants. The best organic cure is to apply a sulfur powder to the infected part of your plants. If you have wrapped up your plants with fleece for the winter such as tree ferns or tender plants its worth paying them some special attention as often the fleece  sheets or bags hold the moisture against the plant and in wet mild winter cause mildews to form which damages the plants. If possible on a few milder days remove the fleece just for the day this will allow the plant to dry out and treat any infected areas with sulfur powder

    Glasshouse - One of the most important elements of growing and plants or crops in a glasshouse is you start clean and disease free. Which means giving your glasshouse a good clean both inside and outside with a disinfectant such as jeyes fluid and using some sulfur candles when you have finished to kill at the over wintering pests and disease which hide themselves in the glasshouse staging and framework

    Colourful summer gardens are all about planning – and that’s especially the case with summer bulbs, corms, tubers, and rhizomes such as Lilies, Gladioli, Dahlias, Cannas and Zantedeschias (Calla Lilies). Now is the time to start thinking about planning your summer colour schemes and also pre-ordering your bulbs so you get the best stock available as soon as possible. Bulbs are delivered from March onwards so you’ll receive them at the right planting time. It is important to remember that most summer-flowering bulbs do not tolerate frost so if you have to store them, even for short period of time, do take appropriate measures to protect them from late frost.
