Environment
The bounded range this crop tolerates. Strict on light; outside the DLI band, yields drop sharply.

- Season
- warm (summer, frost-sensitive)
Growing systems
Root mass: very heavy. Thin-channel systems can't hold this crop.
Growing media
| Medium | pH effect | Retention | Bacterial surface |

| Soil-based mix (Potting soil) | varies | high | high |
Nutrient demand by stage
NPK ratios are relative weights. EC targets shift through the plant's life.
| Stage | N | P | K | EC (mS/cm) |
|---|---|---|---|---|
| seedling | 2 | 1 | 1 | 1.2 |
| vegetative | 2 | 1 | 2 | 1.6 |
| flowering | 1 | 1 | 2 | 1.8 |
| fruiting | 1 | 1 | 3 | 1.8 |
Companion-growing notes
- High transpiration. Regular reservoir top-ups needed during fruiting.
Aquaponics suitability
Not recommended
Fish waste alone doesn't supply enough of what this crop demands. Grows in hybrid systems with supplemental dosing, but expect active management.
Care notes
An excellent container fruit tree for greenhouse and outdoor aquaponics integration. Large container (40 L) with well-drained media. EC 1.5-2.5 mS/cm. pH 6.0-7.5. Temperature: 15–35°C for growth; most varieties need a brief dormancy period (exposure to 2–7°C for 100-300 hours, depending on variety) for best fruiting. Some low-chill varieties ('Celeste', 'LSU Purple', 'Violette de Bordeaux') need minimal chilling and can be grown with only 2-4 weeks of cool exposure. Full sun (DLI 18-30 mol/m2/day). Parthenocarpic varieties fruit without pollination, which is critical for indoor growing. Many fig varieties produce two crops: the breba crop (early summer, on last year's wood) and the main crop (late summer/fall, on current year's growth). Prune in late winter to control size and shape. Figs in containers need consistent watering; drought stress causes fruit drop. Root-binding (slightly pot-bound conditions) actually improves fruiting. Fig rust is the main disease in humid climates; avoid wetting the foliage. Each mature container tree produces 2–10 kg of fruit annually.
Notable varieties
| Cultivar | Type | Days | Notes |
|---|---|---|---|
| Brown Turkey | open pollinated | 730 | Common type, brown-purple fruit. Zone 6-10, the most cold-hardy widely-available fig. Productive, reliable, the variety most home garden 'figs' are. |
| Celeste | open pollinated | 730 | Common type, small brown-purple fruit. Sometimes called 'sugar fig' for the high sugar content. Closed-eye fruit (the opening at the bottom stays closed), so resists splitting and wasp invasion. Excellent for the South. |
| Black Mission | open pollinated | 730 | Common type, deep purple-black fruit. The variety most fresh figs in US supermarkets are. Zone 7-10. Productive, large fruit. |
| Chicago Hardy | open pollinated | 730 | Common type, very cold-hardy (zone 5-6 with protection, sometimes survives zone 4). Brown fruit. The variety to grow if you live in cold continental climate. |
| Kadota | open pollinated | 730 | Common type, yellow-green fruit. Zone 7-10. Drying-and-canning variety; the variety most commercial 'fig newton' filling is. |
