What fruit and vegetables can I compost?

Monday, 3 February 2014  |  HOTBIN Composting

Nearly all types of fruit and vegetables can be added to your HOTBIN composter, although some are more practical to add than others and the time taken for them to decompose varies.

We have created a table of some of the most common FAQs to make things a little easier for you.

We recommend that any large pieces of fruit and vegetables are cut up into pieces <4cm to speed up their decomposition.
