Kelp as fertiliser/plant food

Chop them up a little, or shred them

Turn the pile, moving inside material out and outside material in. Turning the pile frequently allows more oxygen to the microorganisms that are creating your compost, which in turn accelerates decomposition. Aerating it every couple of days will create compost faster than aerating it weekly.

Cover the pile with a plastic tarp. This keeps moisture in during dry weather and excessive water out during rainy weather.

If you want your compost pile to speed up even faster, commercial accelerants, which contain concentrated amounts of microorganisms already in your compost pile, are available in both organic and non-organic formulas. Or you can try home solutions, such as fresh grass cuttings, coffee grounds, aged livestock manure, beer, or rabbit food pellets. These are nitrogen-rich and will jump-start a lagging compost pile.
