Sea sand has been used instead of lime in Cornwall for hundreds of years.
This sand is dredged from Padstow or Hayle esturies and will help your soil to grow amazing crops of top quality vegetables. The NV is around 25%.
Sea sand will last a lot longer in the soil than lime at least 6 years. Not only does it raise PH levels, but will eliminate or reduce clubroot and keep slug and snail numbers down also vegetables taste better.
I would put on plenty when you transplant any brassica plants. Sold by volume but approx 13.5 kg. Packed in recycled storage containers.
