Crocus sativus grows best in USDA zones 6–9, with hot, dry summers and cool, mild winters. Mediterranean climates are ideal. For colder regions, consider growing in containers and overwintering indoors.

Saffron thrives in full sun—aim for 6 to 8 hours of direct sunlight per day. Shady spots will result in fewer flowers and weaker growth.

Saffron bulbs are moderately frost-tolerant but should be planted deeper (15 cm) in colder areas. In extreme climates, dig them up and store during winter.

Yes, but avoid planting near heavy feeders. Saffron does well with other bulbs and low-nutrient plants like lavender or thyme in well-drained beds.

Saffron thrives in well-drained, sandy or loamy soil with a neutral to slightly alkaline pH (6.5–8). Heavy clay or waterlogged soil can lead to bulb rot. If your garden has poor drainage, raised beds or sandy amendments can make a big difference.

Yes! Growing saffron bulbs in pots is a great option for gardeners in colder or wetter climates. Just ensure the container is deep (at least 6–8 inches), drains well, and is placed in full sun. Use a sandy soil mix and avoid overwatering.

Saffron grows well in USDA zones 6 through 9, which includes much of the southern and western United States. It needs hot, dry summers and cool (not freezing) winters—mimicking its native Mediterranean climate.

Saffron bulbs prefer a dry summer dormancy and light watering during active growth (fall to early spring). Overwatering is a common mistake—aim for moist, not soggy, soil once green shoots appear.

While saffron is traditionally grown outdoors, it’s possible to grow saffron indoors or in greenhouses, especially in regions with extreme climates. Provide bright light, mimic natural temperature shifts, and ensure excellent soil drainage to succeed.
