When Do Four-Season Chrysanthemums Bloom? A Detailed Guide to Their Blooming Period

The four-season chrysanthemum is a type of chrysanthemum, and the cultivar commonly grown in China is the dwarf four-season chrysanthemum, so when do four-season chrysanthemums bloom?

1. Growth Habits of the Four-Season Chrysanthemum

The dwarf four-season chrysanthemum originated in Europe, and its flower colors are diverse, including yellow, red, pink, purple, and white petals with a red center. Its stems are thick and hard, so it does not easily lodge. Grown in the open field, it is extremely cold-hardy, and it can bloom once the temperature is above 15°C. In northern China, its blooming period lasts nearly 300 days.

The dwarf four-season chrysanthemum is suitable for large areas of green vegetation, and it is used for flower beds, courtyard decoration, potted flowers, or cut flowers supplied to the market year-round. Skillfully mastering propagation techniques is the guarantee of improving economic returns.

For spring cultivation, when the ground temperature is above 5°C, take offshoots from two-year-old plants and raise seedlings in the open field or in pots. When the natural temperature is below 15°C, they should be cultivated in a warm greenhouse, and they can take shape and bloom for market in as little as five [weeks].

2. When Do Four-Season Chrysanthemums Bloom?

If cared for properly, four-season chrysanthemums can bloom all year round. The specific blooming time is related to factors such as cultivation techniques and climate, and they can generally bloom once the temperature is above 15°C.

The four-season chrysanthemum is highly adaptable, growing well in southern acidic soil, central China's alkaline soil, and northern black soil. Fertile, loose sandy loam rich in humus is most ideal. For open-field cultivation, the soil should be finely plowed and harrowed with sufficient base fertilizer, preferably applying 3 cubic [meters] of decomposed cow, horse, and sheep manure and 30 kg of NPK compound fertilizer per mu.

3. Propagation Methods for the Four-Season Chrysanthemum

Propagation is carried out by the offshoot division method and the new-branch cutting method:

1. Offshoot division can be done at any time when the temperature is above 5°C, and new-branch cuttings can be taken in the rainy season or autumn. The basic requirements are moisture retention and shading;

2. Cutting seedlings fear direct strong light most, so cuttings must be shaded. Cuttings root after 15 days. Once they have fully survived, remove the shade net to harden the seedlings. When the seedlings are 8-10 cm tall, pinch the tips to shape them, and after they take shape, transplant them or put them in pots.
