Troubleshooting
Chinese Artichoke problems — and how to fix them
Chinese Artichoke (Stachys affinis) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Invasive spread
Tubers left in the ground at harvest resprout and the clump wanders. Lift thoroughly each year or contain it in a bed or large pot.
Small, knobbly tubers
Poor or compacted soil gives tiny, deeply crevassed tubers that are tedious to clean. Grow in loose, fertile soil and keep moisture steady through autumn.
Drying out at bulking
Late-summer drought checks tuber formation. Mulch and water through dry spells when the crop is sizing up its rhizomes.
Storage shrivelling
Thin-skinned tubers dehydrate quickly once lifted. Leave them in the ground and harvest as needed, or store in damp sand or a sealed container in the fridge.
