gj, it's not a fool proof way of keeping slugs and snails at bay and doesn't kill them but after watching a programme a few years ago where a guy was growing, if I recall, hosta's and started spraying in March and had the most amazing plants with not a nibble taken out of the leaves, I spray early.
If you decide to make seaweed feed, it's usually good to bottle up after about 6 wks and the stuff in the bags can be spread on you beds. I put it on the bed in the GH and had a really good crop of toms this year. I dilute down to half a litre milk carton measure to a full watering can but using a full milk carton occasionally doesn't seem to do any harm if you miss a feed. I feed weekly.
I used to dive near St Abbs in my youth, not sure if that's near you but kelp grows to several feet high and seals use it to hide in. Don't want to preach but don't pick fresh seaweed the stuff washed up is good enough for the garden.
