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.
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.
