We ve just moved into a new house with a very over grown hedge. How should we trim it and when

01:00 Tue 03rd Jul 2001 |

A.� That depends. Evergreen hedges should be tacked in mid-late spring whereas deciduous ones, ones that shed their leaves in winter, need to be dealt with in winter. Try to stick to these times, unless the local council is threatening to take action over greenery over-hanging the pavement.

Getting the hedge back in shape is not hard, but hacking it in one go will do more harm than good. It takes a couple of years of sympathetic pruning. In the first instance cut back one side to within 10-12cms of the framework, the trunk. Next cut back about a third of the growth. Repeat the process in reverse the following season and you should have a healthy, uniform hedge.

With all hedging it is best to aim for a slight taper from top to bottom, the bottom being fatter. This makes it more wind resistant and discourages snow settling.

Q. What are the best tools to use

A.� For the heavy work an electric hedge strimmer is effective and saves a lot of time and effort. Always wear some sort of eye protection as there are liable to be branch fragments flying all over the place and use a current breaker, especially if you need to work on steps as this is a messy business and it's not always that easy to see where cables are.

For more genteel trimming a pair of sharp shears or secateurs should be all you need with possibly a pair of long-handled secateurs to reach the upper reaches of a tall hedge.

Q.� Do you need to look after well-established hedges

A.� It is always a good idea to mulch or fertilize and water around the base of the hedge. Well-established hedges tend to impoverise the soil around them and make it dry. Not only does improving the soil at the base help the hedge, but it also makes it easier to plant other things beneath it.

A good old reliable that will grow in virtually any conditions is vinca (periwinkle),�which flowers from purple to white and also comes in variegated form. If you make the effort to improve the soil regularly, plant daffodils for spring and autumn-flowering cyclamen.
