Reusing compost

Liam Mulderry asked 12 years ago

I’m using a good quality John Innes for growing veggies and it’s very successful this year. Can I reuse this compost next year if I remove roots and add some nutrients. If so what fertilizer would you suggest I go for and how much per sq ft.

Unless you have no soil, it is not necessary to use John Innes compost, which is mostly soil-based. Any compost can be used again as long as it have not got any plant diseases.

If you are using this in pots, simply liquid feed. If there is a bigger quantity, as in a raised bed, use 3 grams of a general fertilizer per litre of compost.
