December
Trees
Winter is a
very good time for planting trees, as they are dormant now and so
less likely to be stressed during planting. Don't plant if the soil
is frozen or waterlogged as this will be very difficult and cause
untold damage to tree roots. Use a quality compost and mix this
into the soil in the planting hole before planting. Choose Rose,
Tree & Shrub Compost for excellent results. This compost is
formulated to improve the soil around the plant roots; it contains
grit to enhance the drainage at root level and also fertiliser to
nourish the roots.
After heavy
winter rain, top up mulches around the base of your trees. Don't
add fertiliser or plant food at this time of year as it could promote
early growth that would be affected by frost and freezing winds.
For large areas use a quality mulch such as Pine Bark or Chipped
Bark that will look more natural under a tree and is better suited
to large open spaces. If the tree is in a small border in the lawn
or part of a smaller ornamental bed choose a finer mulch such as
Mini Chipped Bark or Cocoa Shell.
Clear up any
leaves and debris from around the base of your trees as these may
harbour a variety of pests and diseases.
Keep the base
of your trees free from grass, as this will compete for vital nutrients
and moisture during the growing season. It can also provide protected
sites for overwintering pests and diseases.
Roses
and Shrubs
Lightly dig
over any bare soil around roses and shrubs to expose overwintering
pests for the birds to eat.
Clear up any
fallen leaves and debris from beneath rose plants to reduce the
chance of black spot and other rose problems from lurking nearby.
Finish planting
bare root roses; dig plenty of Rose, Tree & Shrub Compost into
the soil in the planting holes to give them the best possible start.
Take a look
around the garden and locate areas that are bare of winter interest
and colour. There are many shrubs that perform during the depths
of winter that can be planted now. For plenty of ideas visit your
local garden centre where you will find displays of seasonal plants
that are looking great now. Make sure you pick up some Rose, Tree
& Shrub Compost too to help them establish more quickly and
give an excellent display year after year. Good plants to choose
include Viburnum tinus 'Eve Price', a lovely evergreen shrub with
attractive pale pink flowers that change to pure white. Mahonia
'Charity' has wonderful scented yellow flowers and rich green foliage
or consider the dogwoods, grown for their wonderful winter stems
and available in a choice of colours for striking winter interest.
Fruit
and Vegetables
Keep the fruit
and vegetable garden free from weeds.
Dig over any
bare soil when the ground is not frozen or waterlogged to allow
the frost to break up thick clods and also to expose garden pests
to the birds. Dig in plenty of Farmyard Manure or Soil Conditioner
to improve the structure of the soil ready for planting in the spring.
Buy seed potatoes
as soon as they arrive in the garden centre. Take them out of their
bags and spread them out on a tray, place in a light, frost-free
place to sprout.
Mulch around
cane fruit with Premium Garden Soil to protect the developing shoots
underground.
Carry out winter
fruit tree pruning, by removing any dead, diseased or crowded stems
and branches. Pay particular attention to the centre of the tree
which can become tangled and overgrown. The outer stems and branches
should be simply trimmed, if necessary, to keep the tree in shape.
Lawns
Sweep up any
fallen leaves and keep the lawn free from any debris.
Use the natural
break in grass growth to have the lawnmower serviced.
Do not feed
the grass over the winter. Fertiliser will speed the grass into
premature growth that will not withstand the weather conditions
and could actually kill the lawn. Instead wait until spring when
feeding will give your lawn the best possible start for the season
ahead.
Root out large
weeds from the lawn and keep the garden weeds under control so that
they cannot seed and spread into the lawn.
Keep off newly
sown or turfed areas of lawn. If a heavy frost lifts new turfs then
use a heavy roller during a dry spell to level them out again.
If you are planning
to sow a new lawn dig over the area during the winter and leave
the soil in clumps on the surface for the frost to break it up.
Use the winter
months as a time to plan and prepare for the season ahead. If your
garden needs a new lawn then plan it out over the winter so that
you are ready for action when spring arrives.
Beds
and Borders
If you haven't
yet done so, tidy the borders removing dead foliage and debris and
cutting back overgrown plants.
Lightly dig
over any bare areas of ground taking care not to damage any plant
roots that may be present. If the soil is poor then add some Soil
Conditioner and work this into the soil.
Keep a watch
out for slugs and snails that may be active in sunny spells. Use
your preferred method of control.
Pots
and Containers
Move any pots
that can be moved to the shelter of a house wall or even into a
cold greenhouse. This will provide some protection against the worst
of the winter weather.
Mulch over the
roots of containerised plants with Mini Chipped Bark or Cocoa Shell
to protect the root ball from extreme cold. Wrap the sides of the
pots with bubble wrap to add further protection to the pot and your
plants.
For some seasonal
winter colour choose some winter flowering plants such as Pansies,
Heathers, the Christmas Rose or young plants of Viburnum tinus 'Eve
Price'. Pot these up into a suitable container using John Innes
Potting & Container Compost and place in a prominent position
near the house so you get the full benefit of the plants.
Seeds
and Cuttings
Check on any
overwintering cuttings and seedlings regularly. Make sure they are
not too wet and are adequately protected with horticultural fleece,
newspaper or sacking during severe weather.
Delay any plans
to sow seeds and take cuttings until the weather improves in spring.
Use the winter
break to order your seeds for the season ahead.
Ericaceous
Plants
After heavy
snowfall gently knock snow from the stems and branches of large
shrubs including ericaceous plants to reduce damage from the weight
of the snow.
House
Plants
Feed and water
flowering houseplants such as Cyclamen, Azaleas, Poinsettias, and
Chrysanthemums. Use Feed-all Plant Food in the ready to use formulation
for fast and easy results.
Foliage plants
should be checked regularly and the compost allowed to dry out between
watering. It is very easy to over-water houseplants and much better
to err on the side of caution.
Move plants
off the windowsill at night to stop them from being chilled when
the temperature drops further. Make sure you place them back in
a light and airy place in the morning so that they can make the
best use of the winter light.
Feeding
Most plants
are not actively growing at this time of year and should not be
fed. The exceptions are flowering houseplants that are encouraged
to be at their best for the festive season. These plants may be
fed weekly with Feed-all Plant Food.
The general
rule in winter is not to feed your plants. An out of season feed
will encourage plants to put on early tender growth that is simply
not strong enough to resist the winter weather.
Soil
Matters
If the weather
is amenable and the ground is not frozen or waterlogged then it
is a good time to dig over bare areas of ground. If you have heavy
clay then leave the clods of clay on the surface for the frost to
break them up. Any soil that has supported strong plant growth will
be in need of a little attention. Dig in some Soil Conditioner into
the soil, this will add valuable organic matter to the soil to improve
drainage, increase the water retention properties and encourage
the activity of healthy soil organisms that breathe life into the
soil. Rose beds and vegetable plots will benefit from a generous
helping of Farmyard Manure. Dig this into the soil now, in preparation
for the growing season ahead.
Mulching
After
heavy winter rain it's a very good time to mulch your garden borders.
In the depths of winter the garden is devoid of excess foliage so
it is much easier to see the soil between your plants and to apply
a mulch. Clear away any remaining garden debris, root out any perennial
garden weeds and apply one of the Westland mulches over the garden
soil. Each one helps to suppress garden weeds, improve and retain
soil moisture and will also insulate plant roots against extreme
cold or heat. Choose Chipped Bark or Pine Bark for large areas or
around big established plants, or for smaller borders, containers
and ornamental gardens opt for Cocoa Shell or Mini Chipped Bark.
