Maintenance of Zinnia chinensis in growth period

when there are 2 ~ 3 true leaves in the seedling of Zinnia, it needs to be transplanted once, and the colonization will be carried out in the middle and late May. Rotten organic fertilizer needs to be applied during colonization. When Zinnia grows to about 15 cm high, it needs to leave two pairs of leaves at the base to pick the heart, so as to promote the growth of axillary buds and enable it to branch and blossom more. After the flower withers, the remaining flowers need to be cut in time to reduce the consumption of nutrients and facilitate the next flowering

Water and fertilizer conservation of Zinnia

In addition to the need for timely watering in the seedling stage, in addition, it is generally not suitable for more watering. But it needs frequent watering in the summer to keep the soil moist. Otherwise, it will cause yellow leaves, small flowers and poor color, and the ornamental value will be greatly reduced. The whole growth and development period is usually covered with thin fertilizer for 3 times. Chlorine and potassium mixed fertilizer was the main fertilizer in seedling stage; Phosphorus fertilizer was the main fertilizer during pregnancy and bud stage; Apply chlorine, phosphorus and potassium compound fertilizer once in the first ten days of September. If too much fertilizer is applied, the plant is easy to grow in vain, resulting in lodging

When cultivating Zinnia as cut flowers, high type seeds should be selected, the heart should not be picked at the seedling stage, and the flowers at the top of the main stem should be used for cutting flowers. Because the tall plants are relatively tall and the stems and branches are easy to break in strong wind, it is necessary to set up pillars in time. In high temperature season, Zinnia grows weaker, blooms poorly and does not seed. At this time, it should be watered frequently. At the same time, it is necessary to prevent and control red spiders in time. After the beginning of autumn, they can continue to grow and bloom

After each flower withers, the remaining flowers need to be cut in time to reduce the consumption of nutrients and facilitate flowering again. At the same time, the fertilizer dominated by phosphorus and potassium fertilizer shall be applied for 1 ~ 2 times. Do not plant continuously in the same land to reduce the occurrence of diseases

Maintenance of potted Zinnia

For potted Zinnia, dwarf species should be selected, and loose, fertile and well drained sandy loam should be used as culture soil for direct sowing; At the same time, it not only needs reasonable watering and fertilization, but also needs to pick the heart 2 ~ 3 times to promote its branches and more flowers. If it is managed properly, a pot of Zinnia can bloom 10 ~ 20 flowers at the same time
