Use a lightweight pair of grabbers with long handles to collect a large amount of leaves at one time. Alternatively, two seed trays do the job just as well.
Choose a relatively gentle, flat-tined rake for sweeping leaves off the lawn and gravel areas of the garden on a daily basis.
A leaf blower - particularly one that also collects and shreds leaves - can be very useful (although some gardeners object to them on environmental grounds), especially on areas that are hard to sweep or rake. Choose an electric one that can be switched from blowing to sucking. Blow the leaves under hedges, where they will provide shelter for wildlife.
Leave the bottoms of hedges untouched to provide shelter for garden wildlife.
Leaves have a habit of jumping out of wheelbarrows when they are on the move, so load them into a couple of large bags. These are lightweight and easy to lift when full of leaves.
A rotary lawn mower is a useful tool. Simply sweep up as many leaves as you can into the middle of the lawn and mow over them. This chops them up and, together with the added grass cuttings, helps to accelerate the composting process in your bin or heap.
