    Hi,
    On my allotment site we are very lucky to have regular free deliveries of fresh seaweed from Paignton harbour.
    Charles, would you suggest using this as a mulch or add it to the compost heap? I am never sure if the salt is harmful to the plants, and so far I have only used it to mulch the asparagus and a few fruit bushes. Also because it is raked out of the harbour it contains a lot of sand at times, as well as a few crabs and cockles.

    Sounds great Amanda, I’d be harvesting it by the truck load! Particularly good on asparagus and sea kale beds, but also a brill addition to the heaps too. Seem to remember Charles witnessing veg growing that was only fed by rotting seaweed and they were doing very well? A fantastic resource to tap in to…

    Yes go for it. Salt is overstated as a ‘problem’, though if you mulch with seaweed in autumn, the salt will wash through. Some salt is good.
    I saw it’s success on Iona in the Inner Hebrides, veg grown in sand.
    Composting it is good too.

    Sorry for the delay in replying, stuff gets in the way.
    We have just taken delivery of the first 3 truck loads of seaweed, and I will be spreading it liberally. Only problem is it gets delivered by the gates of our allotment site, and my plot is up the top of the hill, who needs gym membership!
