Those intended for storing should be dug up as soon as they are fairly ripe, unless they are attacked by the disease, in which case they must be taken up as soon as the murrain is observed; or if they are then sufficiently developed to be worth preserving, but not fully ripe, the haulms or shaws should be pulled out, to prevent the fungus passing down them into the tubers; this may be done without disturbing the tubers, which can be dug afterwards.
In the book, the house of Shaws is a muckle big house but muckle big house but muckle is dropped.
By now the green shaws will be coming through, so top up with spare compost.
