Surely even just taking them somewhere and doing nothing more than throwing them on the ground is better than throwing them out as garden waste? Or better still plant them?
The green waste wheelie bin we use goes to recycling as fertilizer so is not wasted. It is not the general waste wheelie bin.
For a couple of years we swept them up – garden is part patio – and tipped them into the woodland behind the garden. Unfortunately this became a series of piles of acorns as they built up on the areas of the floor that didn’t ‘absorb’ them. Compost bins were also no use as we filled six with oak leaves and acorns in the first autumn we were here and ended up just emptying and throwing away the uncomposted results 3 years later.
Plant them? Can you suggest what to do with 6,000,000 oak saplings? If you want some then I can give you 20-30 in the spring that will have self set, just for the cost of postage.
