I hadn’t known what to expect. Three Jazzy seed potatoes were
planted on the patio in March, each in a small black polythene bag (provided by
Thompson and Morgan). In mid-June, the
foliage yellowed and died, so I cut it down. Then I emptied one of the bags and was
delighted to discover that one potato had become about 20 of a size large enough
to eat, plus a lot more that hadn't got much bigger than peas. The Thompson and Morgan
website talks about 80 tubers from one seed potato, so maybe I didn’t water
them enough.
Anyhow, there’s enough from that bag for several meals, and I have
yet to investigate the two other containers.
