Florence Fennel 'Orion' problems — and how to fix them
Florence Fennel 'Orion' (Foeniculum vulgare var. azoricum 'Orion') 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.
Bolting under stress
Although bolt-resistant, transplant shock, cold spells, or drought can still trigger flowering. Minimise root disturbance and keep moisture even.
Poor bulb fill
Sparse or thin bulbs follow overcrowding and low fertility. Thin to 25-30 cm and ensure rich, moist soil.
Aphids and leaf miners
Sap-suckers gather in foliage; leaf miners tunnel the leaves. Rinse off aphids and remove mined leaves promptly.
Slug damage on seedlings
Young plants are grazed at soil level. Protect emerging seedlings with barriers or traps in damp weather.
