Feverfew cultivation management

Cold-resistant, not high-temperature resistant, suitable growth temperature is 15 ° C to 25 ° C, flowerbed cultivation in the open field can be safely overwintering above 5 ° C, long-term low temperature below -5 ° C, the leaves are frozen, dry and yellow, and can still be when the temperature rises Sprout leaves, pregnancy buds bloom. White chrysanthemum avoids high temperature and humidity. As the temperature rises in summer, the flower fades, and the growth above 30 ° C is poor. It can be prolonged in a cool and ventilated environment.

Little white chrysanthemum is highly adaptable and does not choose soil, but it grows best in loose, fertile, humid loam or sandy loam

. The culture soil is usually kept moist, and it should not be too wet for a long time, causing rotten roots and affecting growth and development. Nitrogen, phosphorus, and potassium compound fertilizers were applied every half month during the growth period in a ratio of 2: 1: 2. White chrysanthemum has many flowers and a very long flowering period, and it is necessary to supplement phosphorus and potassium fertilizer in time. After flowering, if you do not leave any seeds, you can cut off the residual flowers at any time to promote the generation of new buds on the side branches, increase the number of flowering, and extend the flowering period.

Feverfew is propagated by sowing, usually in autumn from September to October, and the suitable temperature for germination is 15 ° C to 23 ° C. When sowing, mix the seed with a small amount of fine sand or culture soil and spread it on the seedbed or seedling tray. The thickness of the soil should be invisible to the seed. Keep it moist and germinate in 5-8 days. After the seedlings are grown, apply a small amount of fertilizer to promote the growth of the seedlings. After 4 to 5 true leaves are grown, they are transferred to a seedbed or nutrition bowl for cultivation. Although white chrysanthemum is cold-resistant, winter seedlings are best placed in plastic greenhouses or cold rooms to allow them to continue to grow, watered and fertilized in time, and flower buds were removed in time to promote their crown diameter. They can be moved outdoors or flower beds the following spring to increase their ornamental effect. .
