Compost Heap tips
Use an aerated waste bin or wooden or wire crate for compost heap, at least 1M squared in size.
Include fresh soil in layers as this introduces organisms to help decompose matter.
Keep compost heap moist.
Turn waste regulalry to aerate the heap.
Do not add meat or dairy scraps as they encourage pests like mice.
Save fruit and vegetable scraps for the compost heap.
Start a compost heap in your garden with left-over fruit and vegetable scraps and garden debris.
Choose organic fertilisers (e.g. horse manure) and try to avoid pesticides altogether.
Encourage wildlife in your garden - put up bird feeders, nest boxes and encourage wild flowers to grow.
Plant trees and plants that are indigenous (local) to your area
where possible as these are adapted to local conditions.
(Local nurseries can advise you).
