The Black Mission is hardy outdoors in zones 7–10 and loves heat and full sun. In its hardiness range it can be planted in the ground, where it may reach 10–30 ft. tall; in colder areas, or where you want to control its size, grow it in a large container that can be moved to a sheltered spot for winter.
Planting
- Choose the warmest, sunniest spot you have — full sun produces the sweetest fruit, though it tolerates part sun. A south-facing wall radiates extra heat.
- Plant in well-draining soil. Figs dislike wet feet, so avoid low spots that stay soggy; amend heavy clay with compost or grit.
- Dig a hole twice as wide as the root ball and no deeper than it grew in the pot. Set the tree so the soil line sits level with the surrounding ground.
- Backfill with the native soil, firm gently to remove air pockets, and water in thoroughly to settle the roots.
- Spread 2–3 in. of mulch over the root zone to hold moisture and moderate soil temperature, keeping the mulch a few inches back from the trunk.
Care & maintenance
- Water. Keep the soil evenly moist the first year while roots establish. Mature in-ground trees are quite drought-tolerant; container plants dry out faster and need regular watering through summer. Steady moisture as fruit swells improves size and prevents splitting.
- Feed. Figs are light feeders. A balanced fertilizer in early spring is usually plenty; go easy on nitrogen, since too much pushes leafy growth at the expense of fruit.
- Light & temperature. Hardy outdoors in zones 7–10. In zones 7–8, protect young trees from hard freezes, or grow in a container and overwinter it dormant in an unheated garage or shed where it stays cold but above a deep freeze.
- Prune. Prune in late winter while dormant to shape the tree and keep it accessible. Remember the breba crop forms on last year's wood, so heavy pruning sacrifices that early crop — prune lightly if you want both crops.
- Pollinate. Nothing to do. The Black Mission is self-fertile and self-pollinating, so a single tree fruits on its own without a partner or pollinating insect.
- Pests & disease. Generally trouble-free. Watch for birds and wasps drawn to ripe fruit, occasional root-knot nematodes in sandy soils, and rust or fruit souring in humid climates with poor air flow.
- Harvest. Pick from June through September. Figs do not ripen off the tree, so harvest only fully colored fruit that hangs and softens, often with the neck bending and a drop of nectar at the eye.
