Liquid seaweed and rose blackspots
Does liquid seaweed spray on rose foliage helps in preventing blackspots and other foliage desease?
Wondering if i should make an effort to spray or just water it in soil.
West Midlands, on the edge of the Black Country
Not tried it as a foliar feed but it’s a good idea to keep roses fed and watered well as that then helps them to fight diseases.
