I鈥檝e always thought about creating the Greatest Hits (or Greatest Myths) for gardeners. There are so many things you should and shouldn鈥檛 do when gardening and creating compost.听
Starting a compost system: Do we really need a 鈥淐ompost Starter鈥 to kick it off?听
The easiest way to make compost is by sticking (roughly) to a ratio of Carbon to Nitrogen of something like 30:1. If you chuck a big heap of chipped wood (C) in the bin, you will need some grass clippings (N) to fire it all off. Even a simple pee on the heap will do the trick, or some Urea fertiliser, or even some old soggy lettuce.听
Crushed egg shells around your vegetables are said to stop the slugs and snails as they won鈥檛 be able to cross the sharp egg-edges with their soft and tender 鈥渇oot鈥. Molluscs do not actually come in contact with the sharp substrate as they glide over the slime they produce themselves!听
And if you put the crushed shells into the compost bin, the calcium will eventually turn into useful calcium 鈥 eventually means 鈥渁 few years later at least鈥, so don鈥檛 bank on a quick-release fertiliser!听 Besides: they don鈥檛 really add a lot of value to your compost.听
Ah! To speed up composting waste material, do we need to turn the heap every now and then?听
Good question! Aeration will indeed help the process a bit鈥 but so do mice and rats digging tunnels for their nests. Perhaps the question should be: how much time do you, personally, have to 鈥渢urn鈥 the compost? Every 3 or 4 weeks.听
Cooked food in the compost bin? 听
Why not? It鈥檚 basically the same as un-cooked food, so why chuck it in the rubbish bin?听
Dead Animals or left-over meat in the compost bin?听
Everything that once lived is compostable 鈥 simple as that. Animals and old meat will take longer and it might start to smell somewhat, but it certainly will compost.听
Can weeds be composted?听
Of course! Weeds are simply plants too and when you pull them out, they will decay and form compost, just like any other organism, but should you?听
That depends on the kind of weed it is and if it has set seeds or survives on a vigorous root-system.听
How fast can you make compost?听
Depends on what you make it from; You鈥檒l need C and N plus support from fungal organisms and microbial life-forms. In general, it鈥檒l go quicker when you are in a warm part of the world and slower in a cool area.听
Here鈥檚 another bit of science: a compost tumbler is usually quite a bit smaller than a wooden compost bin, sitting on the soil. That means the tumbler won鈥檛 heat up as much (or at all!) as the larger bin and that may slow the process down 鈥 but it certainly will work albeit not so fast.听
What can we Learn FROM Nature making its own compost?听
Leaves fall down; twigs and sticks break off and join the leaves. Fruit and seeds join the party and every now and then a big branch with deliver a lot of Carbon.听
鈥淩ecycling insects鈥 and Microbes help the compost process out; worms transport the end-product to deeper layers in the soil where it鈥檚 needed by the roots鈥 and it just carries on in its own tempo鈥听
