The flowering period of the blue flower is from May to June, and the flowers are blue-purple. It is a kind of ornamental, foliage and flowering tree species, which is widely used as street tree species. The following is to introduce you about the blue flower planting technology.

Planting techniques of Carpinus paniculata

1. Reproduction

The blue flower can be sown and propagated at a temperature of about 20 degrees, or it can be propagated by cuttings in spring and autumn, and medium-ripe branches should be selected for cuttings; it can also be propagated by tissue culture.

two。 Sowing seeds

Soak the seeds before sowing the seeds, soak them in warm water of about 30 degrees for 2 days, then plant them in the soil and emerge in about 20 days. Generally speaking, it can be fertilized once after the seed is sown, and a large amount of water should be poured into the seedling after emergence, and weeding and loosening the soil should be carried out. When the seedling grows to 20 centimeters, it is necessary to replenish the seedling and interseedling in time.

3. Water and fertilizer

For the fertile and moist sandy loam or loam, sufficient basal fertilizer should be applied when planting, topdressing once in spring and autumn after survival, pruning once in early spring every year, and heavy pruning should be applied to aging plants. When potted, it can be dried or grafted and dwarfed, and watering and nitrogen fertilizer can be controlled.

4. Pest control

The disease of blue flower is less, and the insect pests are mainly longicorn beetles. if reddish-brown dung shavings are found at the base of the trunk, a knife can be used to pick up the bark cortex to catch larvae; before the occurrence of adults, a mixture of 10 parts of quicklime, 1 part of sulfur and salt can be applied below 80 cm of the trunk to prevent adults from spawning.

If the blue flower is planted by the method of seed sowing, the seeds of the same year and full grains must be selected, so as to lay a good foundation for the later growth.
