Care at a glance

Light

Fig 'Black Mission' needs sun on the leaves, not just bright ambient room light. Demands full sun and abundant heat to ripen its two crops. Position in the hottest, most sheltered spot; insufficient sun and warmth leave fruit hard and unripe. A south or west-facing windowsill in the northern hemisphere is the default; anywhere else, expect the plant to stretch and pale out within a season.

Watering

Outdoor fig 'black mission' crops want deeply once or twice weekly in summer; reduce sharply in winter. The single best habit is a finger-test before watering — push a finger 3-4 cm into the soil. Damp = wait a day; dust-dry = water deeply at the base of the plant. Provide consistent moisture during the breba and main crops, then taper as figs ripen to deepen flavour. Containers need frequent summer watering; uneven moisture triggers splitting and premature drop.

Soil and pot

Fig 'Black Mission' grows best in deep, free-draining loam, neutral to alkaline. Tolerant of poor soils but performs best in fertile, well-drained ground. Root restriction encourages cropping. Use a soil-based potting mix with added grit for container culture. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Fig 'Black Mission' sits happiest at around Ambient outdoor humidity and 18-32C (growing); hardy to about -9C dormant (64-90F (growing); hardy to about 16F dormant). A Mediterranean-climate fig that prefers warm, fairly dry air. Damp, humid conditions raise the risk of fruit souring and fungal leaf spot. If you keep the room above 18 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed fig 'black mission' sparingly. Feed container trees with a high-potash liquid fertiliser every one to two weeks through the growing season. In the ground, only feed poor soils lightly; surplus nitrogen favours foliage over the heavy fruiting this cultivar is known for. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on fig 'black mission' in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Unripe or dropped fruit in cool summersThis cultivar needs more heat than most; in cooler regions the main crop may not finish. Grow under glass or in the warmest sheltered position.
  • Fruit souring / spoilageIn humid weather, the open eye (ostiole) lets in yeasts and vinegar flies, fermenting fruit. Harvest promptly and remove spoiled figs.
  • Splitting from irregular wateringDrought followed by heavy water bursts the skin. Mulch and keep moisture even during fruit swell.
  • Winter cold damageLess cold-tolerant than 'Brown Turkey'; stems and embryo figs suffer below about -9C. Wrap or overwinter containers under cover in frost-prone areas.

Propagation

Propagated from hardwood cuttings of dormant winter wood, or by air-layering, to keep the cultivar true. Roots readily in gritty, free-draining compost. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Fig 'Black Mission' is toxic to pets. ASPCA lists fig (Ficus) as toxic to cats, dogs and horses. Foliage and white sap contain ficin (proteolytic enzyme) and psoralen (ficusin), producing drooling, oral and GI irritation, vomiting and phototoxic skin reactions. The ripe figs are safe and prized for people; keep pets from the leaves and sap. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.

What is the common name for Ficus carica 'Black Mission'?

Ficus carica 'Black Mission' is most commonly called Fig 'Black Mission', but it is also known as Black Mission fig, Mission fig. The names refer to the same species, so care instructions for Fig 'Black Mission' apply identically to anything sold as Black Mission fig.

How often should I water fig 'black mission'?

Water fig 'black mission' deeply once or twice weekly in summer; reduce sharply in winter. Provide consistent moisture during the breba and main crops, then taper as figs ripen to deepen flavour. Containers need frequent summer watering; uneven moisture triggers splitting and premature drop. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.

Is fig 'black mission' toxic to cats and dogs?

Fig 'Black Mission' is toxic to pets. ASPCA lists fig (Ficus) as toxic to cats, dogs and horses. Foliage and white sap contain ficin (proteolytic enzyme) and psoralen (ficusin), producing drooling, oral and GI irritation, vomiting and phototoxic skin reactions.
