Ficus carica is a deciduous fruiting tree or large shrub that produces soft, sweet fruit in late summer and fall. In cold-winter zones it sits at the cold edge of its range and is usually grown as a multi-stemmed shrub or in a container so it can be protected or moved. Hardy varieties like 'Chicago Hardy' and 'Brown Turkey' are the most reliable choices here.
Figs fruit on both old and new wood, but in cold climates the main crop comes from new growth after winter dieback. Plants need winter protection in this zone - either wrapping, burying the canes, or moving containers into an unheated garage or basement. Roots often survive even when top growth dies back, and the plant will resprout in spring.

Orange to brown raised pustules on the undersides of leaves, with yellow spotting on the upper surface. Heavy infections cause leaves to yellow and drop.
Remove and destroy infected leaves. Avoid overhead watering and improve air circulation. Apply a sulfur or copper-based fungicide if it spreads. Clear plant debris in fall.
Mosaic virus
Yellowing, mottled, or distorted leaves. No cure - spread by aphids.
Remove and destroy infected plants. Control aphid populations to prevent spread. Do not propagate from infected tubers.
Botrytis (grey mould)
Grey fuzzy mould on petals and stems, worst in cool wet conditions.
Remove affected parts immediately. Improve air circulation. Avoid overhead watering. Apply copper fungicide if severe.
Root-Knot Nematode
Swollen galls on roots, poor vigor, wilting in heat, and reduced fruiting. Containers and sandy soils are more prone.
Use clean potting mix in containers. Avoid replanting in infested soil. Maintain plant vigor with mulch and steady watering. Solarize affected garden soil.
