Gardenia 'Kleim's Hardy' problems — and how to fix them
Gardenia 'Kleim's Hardy' (Gardenia jasminoides 'Kleim's Hardy') 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.
Bud drop
Flower buds yellow and fall before opening due to fluctuating temperature, dry air, over- or under-watering, or being moved. Keep conditions stable and humidity up while budding.
Leaf chlorosis
Yellowing leaves with green veins signal alkaline soil locking out iron. Use ericaceous feed and chelated iron, and water with rain or distilled water.
Spider mites and scale
Dry indoor air invites mites (fine webbing, stippling) and scale. Inspect leaf undersides, raise humidity and treat with insecticidal soap or horticultural oil.
No flowers
Insufficient light or excess nitrogen produces leaves but no buds. Give bright light and a warm-day/cool-night swing; switch to a bloom-supporting feed.
