Tools & Equipment

Secateurs
Will cut up to 1cm thick. Buy the best you can and make sure there is no gap between the blades or they will tear the plant and cause disease.

Loppers

Will cut over 1cm thick but do not force or the blades will bend.

Little pruning saw
Will cut up to 3cm thick, can get into tight spaces.

Bow saw
Cuts 3cm or over. May not be able to get to all the parts you need to remove.

Keep all the blades clean to prevent diseases – use disinfectant, tomato ketchup or meths.


Pruning

Why?
If no reason don’t

What plant?
Do not prune fruit in the winter because it will get diseased.

If the plant is too tall or over windows or other plants, dig it out and replace somewhere else as it will grow back the same size unless the roots are pruned too.

Bushes with alternating buds
Cut off just above an outside growing bud with a slanting cut.

Bushes with two opposing buds
Cut just above the buds straight across.

When removing branches do not cut too close to the main stem as it will not heal well.

Unbalanced branches
Cut the long side long and the short side hard so it will grow back more evenly.

What?
Remove dead, dying, diseased or damaged parts. Remove thin spindly and crossing branches.

Once you have done this, step back and look at what is left, you may not need to cut any more. Do not prune, Japanese Maples, azaleas or hammamelis.


Roses

Bush Roses
Prune mid to late March. Remove suckers, dead wood, crossing branches, anything in the centre of the bush to allow air in. Leave stems about 6” long.

Hybrid Tea
As above but cut back to 4”.

Climbing Roses
Remove small shoots, tie horizontally so it will flower (vertical growth will not flower) any new growth bend horizontally and tie between other branches if possible.

Rambler Roses
Prune straight after flowering by removing old wood.

Winter Flowering shrubs
e.g. cornus, prune in March. Cut above a bud about 2/3 inches above the ground. Remember to prune each or every other year or colour will be lost.

Most evergreens don’t like to be pruned. Any variegated plants that have turned green on top remove the green parts in Spring.

Hydrangeas
Remove dead heads in spring and any dead wood and then leave alone.
