Jobs for Winter: 

January: During mild spells, prune out dead or diseased branches from deciduous trees whilst they are bare. Treat the cuts with a pruning compound to seal them up

February: Spray your fruit trees, bushes, roses and any other bare branched plant with “Winter wash” to kill over-wintering insect eggs. (Particularly effective on roses as the last generation of aphids leave eggs as a parting “gift”). The “wash” consists of an enzyme that dissolves the eggs.

March: Start to hoe through annual weeds to prevent their flowering and seed production and be on the lookout for early herbaceous perennial shoots – the slugs will be waiting!

May: Basil plants will form a woody-stemmed, small shrub if grown under cover. Six to eight plants in a grow bag will give a lot of “Come and cut again” foliage.

June: Spray roses for disease as prevention is better than cure.  Now is the time to kill the moss on paths and patios.

Jobs for Autumn: 

October: Now is the time to think about purchasing new plants.  It is also the time to plan your fruit garden, as now you will find the best selection of fruit trees and bushes.  Treat your lawn to an Autumn feed.

November: As an interim pruning measure, trim your bush rose with garden shears to remove the top weight.  This just protects them from winter gales. Complete the “fine pruning” in the Spring, once the last frosts have gone. Remember that floribunda roses should not be cut back as hard as the single-stemmed varieties.

December: To discourage over-wintering pests (both insect and fungal), clear away the remaining fallen leaves. These are best stored in a wire cage (e.g. chicken wire) to rot down into leaf mould.
