A Pleased Hubby! By Anonymous 5 28th November 2014

I purchased a double compost bin, was very pleased with it so added to it along with the lids. The triple bins are now installed and starting to do their job. Hubby was pleased with the instructions etc.

Ease of Use By Anonymous 5 10th November 2014

Great once assembled. I would add to the other reviews that I would happily have paid more for the product if all the metalwork came pre-attached

3 Bay Starter System By Anonymous 4 2nd October 2014

Once assembled these bins have a pleasant appearance,ideally suited to a home garden. The design of the posts means you can easily extend the system with additional bins on any of the exposed sides and the slatted sides make it easy to get access to your compost from the side as well as the top of the bins. The wooden corner posts are well made and come with metal plates that are attached on each long edge to create grooves down the sides of the post. A small metal plate is attached to each end of each side plank and this then slots into the grooves on the posts. Now the bad news: each corner post needs 6 or 8 metal plates attached down its sides (depending on whether it is on an extrenal corner or not). Each of these plates has 10 screw holes. Each post has to be pre-drilled for each of the screws (60 - 80 holes per post x 8 posts = 560 holes followed by 560 screws). There are 40 side planks each needing a metal plate screwed to each end with two screws per plate. These do not need pre-drilling, thank goodness, but that's still another 160 screws. With an electric screwdriver there is several hours work to pre-drill and screw all the plates to the posts and planks. I wouldn't attempt it without. The end result looks good and is pretty solid. It's a real shame that some of the assembly cannot be done by the supplier rather than the Customer.

What can go in to a conventional bin and how does it all work?

Success depends on heat, biology and a good balance of ingredients, added in approximately 10cm. layers.  ‘Green’ waste (grass, border and hedge trimmings, snipped or shredded woody prunings) heats up steamily, starts to break down rapidly and can be stirred into layers below to speed everything up.  ‘Brown’ waste (e.g. shredded paper, packaging and straw) should be added at regular intervals to counteract the wetness of the greenery and will rot down too.  Manure from herbivores (chickens, pet rabbits) adds zest to the whole mixture, as does the odd spadeful
of soil.

Autumn leaves are best composted on their own in hessian bags or cages, since they rot down more slowly and in a different way.

What shouldn’t go in?

Moss (which refuses to rot and can therefore be unwittingly spread around)
Seeding weeds or garden thugs (i.e. Verbascums, Fennel) Roots of perennial weeds such as ground elder and bindweed – unless they are thoroughly dried off in the sun first. Cat and dog (i.e. carnivore) manure. Meat or cheese kitchen scraps or vegetable waste that has been contaminated by them.

Common problems

Too dry?  Water the heap and/or add more greenery and cover it tightly to keep the heat in.

Smelly?  Add more ‘brown’ ingredients, but no grass clippings or kitchen waste for a while.  Stir the contents to open it up.  Leave the lid off.

Rats? This is a tricky one - they may try to move in if there is a regular source of food nearby (i.e. a bird table or poultry house).

Slugs and snails?  No problem.  They are doing their bit for the composting process, and at least it keeps them away from your lettuces and hostas.


Our Horticulturist says; "Home composting is a must for any serious gardener. Well rotted compost adds essential organic matter to soil along with humus and greatly improves structure and the soil's ability to hold onto water and nutrients.

What's more, home composting is free, can be easy and greatly helps the environment as less compostable material makes it to landfill sites where it produces harmful methane gas - and you cut down on trips to the garden centre to buy compost too. It's a win/win situation!

It's also surprising how much compostable material your garden and kitchen produces; of course there's the usual, stems, deadheaded flowers, leaves and spent plants from the veg patch or border but don't forget kitchen peelings, cardboard and newspaper from inside the house. Filling a bin or building a heap is never a problem!"
