Garden and grounds maintenance throughout the year.



January

Often the coldest month

January might be the middle of winter but as the days lengthen the garden starts to grow. Now is a great time to plan for the coming gardening year and to order seeds and plants. Enjoy the fresh air, on dry sunny days, and check your winter protection, stakes, ties and supports are still working after any severe weather. Also put out food for birds and leave some garden areas uncut, a little longer, to provide shelter for wildlife in your garden.

Lawns

lawn repairGeneral maintenance

  1. If the weather is mild you can lay a new turf or repair hollows and bumps in an existing lawn. To repair the lawn, make a ‘H’ shaped cut in the turf, peel back the grass and either fill the hollow with loam, or scraping away the soil from a bump. Re-lay the turf, press it into place and pinch the cut edges together.

    Repair lawn edges, especially around flower and shrub beds, with turves cut from other areas of the garden.

    If your lawn suffers dieback from treading during the wet, muddy season, then consider laying stepping-stones through it to allow easy access across it without causing damage.
     


molehills in lawnTroubleshooting

  1. Remember not to walk on frosty grass as this will burn or scorch the grass and the grass will appear to be black and have brown footprints after a while.

    Watch your lawn for signs of waterlogging, as the weather gets wetter. If you missed the opportunity to carry out autumn lawn maintenance, then you can still remedy the situation a bit, by spiking the lawn with a garden fork or mechanical aerator. Then fill the holes with a mixture of sharp sand and loam, brushed in using a stiff broom.

    Mole activity will increase in January and February due to mating and nest (fortress) building. Remove the largest hills and re-firm before overseeding in spring.

    Keep brushing away worm casts, as they can be troublesome at this time of year.

    Fusarium patch or snow mould may be a problem in wet weather, particularly on overfed and lush lawns that have been left a bit too long.

    Algae can be a problem on lawns where there is poor drainage, excessive shade, or under the drip-line of trees. 

Trees and shrubs

Fragrant Hamamelis mollisPlanting and moving

  1. Plant roses, but avoid areas where roses were previously grown as this can lead to problems with replant diseases.

    Continue to plant bare-root deciduous hedging plants and trees. Stakes should be put in place before the rootball to avoid damage to the roots.

    Move established deciduous trees and shrubs, provided the ground is not frozen or waterlogged.

    Take note of the most vibrant dogwoods (Cornus)Salix and white-stemmed Rubus shrubs for a display of coloured stems.

    Seek out scented winter shrubs, such as Hamamelis ,Sarcococca and Chimonanthus, when visiting gardens open to the public, or in garden centres, and consider planting them for a winter display.


Staking a cornusWinter maintenance

  1. Check tree ties and stakes on established plants. Replace, tighten or slacken them where necessary.

    Firm back newly planted trees and shrubs if they have been lifted by frost heave or strong winds.

    Protect newly planted trees, hedges and shrubs from cold winds and frosts. Erect a temporary netting windbreak if there is no natural shelter. Thick dry mulches will protect the roots from cold, and branches can be covered with straw or bracken, and secured with fleece and ties, to protect them from frost damage. A wooden frame with clear polythene stretched over it does a similar job for evergreens without blocking the light, but don’t let the polythene touch the leaves, as condensation could freeze or cause rots.

    If there is snow in your area, then you may need to brush it off the branches of conifers, climbers and light-limbed shrubs and trees. Heavy snowfall can splay branches, break limbs and spoil the shape of the tree.

    Remove weeds from around the bases of young trees.
     


winter tree pruningPruning and training

  1. Pruning and renovation of many deciduous trees, shrubs and hedges can be carried out from now throughout the dormant season. It is easier to see what you are doing when the branches have no leaves. Suitable examples are: Fagus (beech), Corylus (hazel) and roses. Exceptions are evergreens and tender plants (best left until spring), and Prunus species (e.g. ornamental cherries, plums and almonds) as these are vulnerable to silver leaf disease when pruned in autumn or winter.

    If your trees are too large for you to manage the pruning alone, then you may need a tree surgeon. Otherwise take care not to damage the tree when sawing off thicker branches.

    Prune Wisteria - cut back the sideshoots shortened by summer pruning to two or three buds. Avoid cutting off flower buds.

    Tie wall shrubs and climbers onto their supports to protect them from wind damage. Ornamental vines, ivy, Virginia creeper and Boston ivy can be cut back now – it’s a good idea to keep them away from windows, doors, gutters and roof tiles.
     


sowing tree seedPropagation

  1. Seeds of berrying trees and shrubs can still be sown - but be quick, as they need a period of frost to break their dormancy. Examples are SorbusCotoneaster and Pernettya.

    Take hardwood cuttings of ornamental shrubs such as CornusSalixForsythiaWeigelaEscalloniaRosaRibesChaenomeles and Elaeagnus. Many deciduous climbers can also be propagated in this way (e.g. Fallopia and Lonicera).

    Check hardwood cuttings taken last year. They may need planting out or potting on.
     


bracket fungiPest and disease watch

  1. Bracket fungi on trees is visible at this time of year. If the tree is in poor health it is worth calling in a tree surgeon for a professional opinion.

    Put rabbit guards around newly planted trees and shrubs to protect the bark from rabbit damage.

    Inspect sick-looking box shrubs and holly trees for signs of blight.

    Phytophthora root rots can cause dieback on mature trees and shrubs. Wet winter weather and poorly drained soils are likely to encourage this problem on susceptible woody plants.

    Coral spot is often noticed once the leaves have fallen from deciduous hedges, shrubs and trees. This problem can be connected with poor ventilation and congested, un-pruned twiggy growth (as found inside clipped hedges).

    Check for damage or cankers on deciduous trees while stems and trunks are readily visible. Prune out torn or damaged branches to prevent disease infection.
