    Hi everyone...I have about 140L of compost that was left over from last year, it's in unopened bags which have been sat outside in the elements from about last July, and I was wondering if I can use this for my Potatoes which will be planted up in 30L pots.

    Thanks

    Andy...:)

    That would be an ideal use for it, as rain leaching in together with microbes, possibly even small worms and slugs (compost bags have perforations) would make it more suitable for sowing/planting larger stuff in. Rain may have leached out some nutrients, but as the likes of potato fertilizer/blood, fish and bone are usually added to MPC for growing spuds, that shouldn't be a problem.

      Thanks very much, Scrungee...I have some blood, fish and bone so I can use that too, how much should I mix in to the first 4/5 inch layer of compost when I first plant the spuds?

      And should I mix in some more b,f and b to each further layer of compost each time I re-cover the shoots?

      I mix a handful of BFB per bucket, then just top up with compost as necessary with no extra feed as BFB is a long term feed. Later when tubers are forming I feed with a very diluted comfrey tea every time I water.
