Planting method of Chrysanthemum morifolium

Tianren chrysanthemum, also known as tiger skin chrysanthemum, tiger skin chrysanthemum, etc., are annual herbs of the Compositae family, which are wind-resistant, moisture-resistant and tough, and can be seen everywhere in Penghu, so Penghu is called Chrysanthemum Island. It has bright colors, long florescence, simple cultivation and management, and is often cultivated in the garden for viewing. Let's take a look at the planting method of chrysanthemum.

Growth habits of Chrysanthemum morifolium

Chrysanthemum morifolium is native to North America and is widely cultivated in the central and southern part of the country. It is resistant to drought and heat, not cold, like sunshine, and semi-shade. It is suitable for loose soil with good drainage, wind resistance, moisture resistance and natural toughness. In acid soil, it is not only difficult to obtain strong seedlings, but also wither the lower leaves in midsummer, fertilizer should be applied early for rapid growth, and the ratio of phosphorus and potassium should be higher.

Propagation methods of Chrysanthemum morifolium

1. Sowing: the chrysanthemum is often sowed in summer, and the seeds are soaked in warm hot water for 3 to 10 hours until the seeds absorb water and expand. After the seedlings are unearthed after sowing, the film should be opened in time, and the seedlings should be exposed to the sun before 9:30 every morning, or after 3:30 in the afternoon, otherwise the seedlings will grow very weakly. When most of the seedlings grow 3 or more leaves, they can be transplanted into the pot.

2. Cuttage: the cutting propagation of Chrysanthemum morifolium is usually combined with heart-picking work, the sturdy, disease-free top tip is used as cuttings, and the optimum temperature for rooting is 18-25 ℃. At the same time, attention should be paid to light management. The stronger the light, the higher the temperature in the cuttings, the more exuberant the transpiration of cuttings, the more water is consumed, which is not conducive to the survival of cuttings.

Planting method of Chrysanthemum morifolium

1. Potting: when the small seedlings of Chrysanthemum morifolium are put on the pot, put broken tiles or coarse sand at the bottom of the flowerpot to make a filter layer, sprinkle some rotten fertilizer as base fertilizer, put a layer of soil on the base fertilizer, and finally put the plant. After potting, water the flowerpot once and keep it in a shady environment for a period of time.

2. Fertilizer and water: like other grass flowers, Chrysanthemum has more requirements for fertilizer and water, but it is required to follow the fertilization (water) principle of "light fertilizer, less fertilizer, more times, and complete nutrition", and keep leaves and flowers dry at night after fertilization. Summer and autumn are its peak growing season. After entering the flowering stage, fertilizer should be properly controlled to facilitate seed ripening.

3. Humidity: chrysanthemum likes higher air humidity, which will accelerate the withering of single flower if the air humidity is too low. Also afraid of rain, need to keep the leaves dry at night, the optimum air relative humidity is 65-75%. Heat-resistant, not resistant to frost and cold, like sufficient sunshine, slightly resistant to half-shade.

4. Pruning: the pruning of Chrysanthemum morifolium is very important to its growth. When the seedlings of Chrysanthemum morifolium grow to more than 6 leaves, the top tip can be removed, which can promote the branching of Chrysanthemum morifolium. After that, it can shape the ideal plant type and promote more flowering.
