How about using my compost for potato barrels ?. What kind of a mixture would you recommend ? I have sand and turf mould available . Richard
If it were to be be used for a potato barrel, it could be mixed with some soil, up to half and half, with some general fertilizer added, at about 1 or 2g per litre.
If you have open soil, it is better to plant potatoes directly. A barrel needs watering but is fine if only a balcony or yard is available.
