Its leaf clumps are slender and stiff, its flowers delicate and elegant, in a variety of colors, with a distinctive fragrance. It is often used as an excellent material for edging flower beds and planting rock gardens, and can also be grown in pots or in water for indoor display. Let us take a look together at the growing methods and points to note for saffron crocus!

Growing Habits of Saffron Crocus

Saffron crocus is native to southern Europe and is commonly cultivated throughout China. It is an autumn-planted bulbous flower that prefers cool, humid and semi-shaded conditions, is relatively cold-hardy, and does best in well-drained, humus-rich sandy loam with a pH of 5.5 to 6.5. The corms lie dormant in summer and send out roots and leaves in autumn. It blooms in late October, with the flowers opening by day and closing at night.

Propagation Methods for Saffron Crocus

1. Division of corms: Saffron crocus is generally propagated in August to September. A mature corm has several main and lateral buds. After flowering, new corms form from the swollen base of the leaf clump. After the above-ground parts wither in summer, dig out the corms, grade them, dry them in the shade and store them. Planting early helps to produce strong seedlings. Plant large and small corms separately.

2. Sowing: Saffron crocus must be hand-pollinated to obtain seed. Once the seed is ripe, sow it immediately in an open-air seedbed or in a pot. The sowing density must not be too high. The plants need to form corms and generally must not be dug up for 2 years. From sowing seed to the plant flowering often takes 3 to 4 years.

How to Grow Saffron Crocus

1. Planting: For growing saffron crocus, choose fertile, loose soil rich in humus. When selecting corms, you must choose robust corms that are large and plump, with no mold spots or disease spots. In autumn, plant the corms in flower pots. In principle, one plant per pot, but depending on the size of the plants and the pot, 4 to 6 plants may be suitably planted per pot. After planting, cover with 5 to 8 cm of soil. Within one week after planting, place the pots in a cool, ventilated spot; after one week they can be moved to a bright spot for care.

2. Watering: Saffron crocus is usually planted in autumn, and winter and spring are its growing season. The climate is cold and dry, so it needs appropriate watering. Seedlings emerge about 20 days after planting; water once before emergence to encourage it. Water once before winter sets in with anti-freezing water to raise the soil temperature. Water once in mid-April to reduce the harm of hot dry winds. When watering, note that when the temperature is low, do not water with ice-cold water; the water temperature should be equivalent to room temperature, so that the potting soil does not freeze and affect plant growth.

3. Fertilizing: Before planting saffron crocus, add plenty of base fertilizer to the potting soil, such as cake fertilizer, barnyard manure, burnt soil, plant ash, chicken and duck manure, etc., and also apply some superphosphate. After rooting, apply a dilute liquid fertilizer with balanced nitrogen and phosphorus once every 10 days. Avoid applying fertilizer that is too concentrated, so as not to cause excessive leaf growth and affect flower bud development. After flowering in October, apply 1 to 2 more applications of a quick-acting fertilizer balanced in nitrogen, phosphorus and potassium to support the growth and development of the corms.

Points to Note for Saffron Crocus

1. Variety selection: Saffron crocus usually blooms in winter and spring. When planting, gardening enthusiasts can choose different varieties according to their needs. It is recommended to choose spring-blooming varieties; the spring environment is relatively better, and storing the corms promptly after flowering results in a longer flowering time.

2. Pot size: For planting saffron crocus, it is best to choose a clay pot 15 to 20 cm in size or a plastic pot with good air permeability, planting 4 to 6 large corms per pot, in September to October. Small pots can also be used, 3 to 5 cm black plastic pots, one corm per pot.

3. Corm storage: In April to May, the above-ground stems and leaves of saffron crocus gradually turn yellow, and the corms can be dug out of the pot and stored. Place the corms in a gauze bag and store them in a place with little light, cool and ventilated, keeping the room dry. They can be replanted in autumn.
