Troubleshooting
Issai Hardy Kiwi problems — and how to fix them
Issai Hardy 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.
Japanese Beetle Damage
Japanese beetles skeletonise leaves in midsummer. Hand-pick in the morning, use row covers on young vines, or apply approved neem oil treatments. Avoid Japanese beetle traps near the vine as they attract more beetles than they catch.
Root Rot (Phytophthora spp.)
Caused by consistently waterlogged soil. Symptoms are wilting despite moist soil, yellowing, and dieback. Ensure excellent drainage and avoid planting in low-lying areas. No cure once established; prevention through soil preparation is essential.
Botrytis Fruit Rot
Grey mould can affect ripening fruits in wet, humid conditions. Improve air circulation by training and pruning the vine, avoid overhead watering, and harvest promptly when fruits soften.
