I've got a whole lot of worm castings ready to harvest - but I've realised from the ones I have been using that I have loads of voleenteer seeds (think 1000's of tomatos) I have heaps of castings so I was using them as mulch on greenhouse pots and on the vege garden - and as a ingredient in seed raising/potting mix.
I've now hot composting and will be using that with worms to be seed free - but in the mean time - I have about a cubic metre of castings that are full of seeds - anyone got any tips, tricks or ideas on how I could de-seed?
