Used compost question

cazsophieq2019 · September 2020

Hi again now in the process of emptying pots of spent veg and fruit plants and have read that I can put resulting spent compost into my compost bin.

So my question:. Is used compost considered as nitrogen green or carbon brown?

My instinct is telling me carbon but I just want to make sure.

Thanks again

You're probably right, but it doesn't need composting. You can spread it straight on the beds/borders as a mulch/soil improver.

Aah ok @JennyJ good to know 🙂

When money was tight, I would dump all the pots into a large plastic tote and pull out all the rootballs without shaking them out for composting or putting on the garden, then mix the used soil with a fresh bag of compost and some slow release fertilizer pellets. I then used this mix for the winter display of pots. Any extra I put back into the compost bag to save for topping up, etc. It was usually fairly equal, the new bag of compost replaced what was taken out around the rootballs for about a 50% new and 50% used. I've also saved old compost for the bottom half of larger pots, again mixed with some slow release pellets. Fresh compost goes in the top half around the plants.

I still do that @Blue Onion

It's particularly good for filling pots for bulbs, when you don't need a load of rich material for them.
I also use it for any seed sowing at this time of year. New, fresh multi purpose is too rich, and it saves buying seed compost.
I mostly use it on borders though.
