Troubleshooting
Issai Kiwi problems — and how to fix them
Issai Kiwi (Actinidia arguta 'Issai') 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.
Light or late first crops
Although self-fertile, 'Issai' often yields modestly and can take a few years to fruit well; a nearby male A. arguta can boost both yield and berry size.
Frost damage to new growth
Spring shoots and flowers are frost-tender and easily lost to a late freeze. Site in a sheltered sunny spot and protect early growth when frost is forecast.
Drying out in containers
Pot-grown plants are popular but dry out quickly, causing fruit drop and leaf scorch. Water frequently in summer and stand the pot out of the hottest, most exposed positions.
Cat damage to young vines
Cats drawn to Actinidia may chew or roll on young plants and snap the stems. Shield new vines with a guard until the wood becomes firm and woody.
