When to prune

When to prune is actually a large question that needs to be broken down into smaller chunks, for example:

• the time of year

• the type of plant or tree

• the location of the plants

• as preparation for a significant event

Most plants and trees are safe to prune in either autumn and/or spring. Some however are generally pruned to some degree in winter, for example fruit trees. Whilst it is now accepted practice to do a main prune on fruit trees directly after they have fruited, so early autumn, it will probably be necessary to do a light prune in winter to remove dead and/or unwanted growth to ensure good airflow and to reduce damage from crossed branches.

For non fruiting plants and trees, the key elements to look out for are heat and cold. If it's too hot there's a strong chance that the pruned plant could suffer due to the fact that the pruning activity causes the plant to initiate a re-growth phase and to do this effectively it needs moisture. Generally in southern Australia hot temperatures go hand in hand with less rainfall, so a potential double whammy for the pruned plant.

Similarly if it's too cold, the shock of pruning may hinder the plants ability to survice a cold winter, or worse be subject to frost burn off. I'm sure you've all seen what a plant looks like after being hit with a nasty frost.

I guess if you're in doubt, look for guidance from your gardener if you have one or your local nursery.

Happy gardening.
