I have three beds at my allotment which I will be mulching with black plastic this year to combat the last area of horsetail and bindweed that is still strong. I was considering sprinkling them with a combination of seaweed meal (a nice Christmas gift!), rockdust and then an inch or so of well rotted cow manure as a top layer. My idea to invest in the soil there for the following season.
Is this a good use of the seaweed meal or would a better use be to sprinkle it on beds I will be growing in this coming season? (I have enough to do a bit of both). I’m not sure how this product ‘works’.
Thanks for any pointers.
