How to accelerate the flowering of chrysanthemum

method

New Year

In mid-August, expose the chrysanthemums to light for about 17 hours a day (this can be non-natural light such as lamps) until they bloom. On the eve of October, let it be exposed to natural light. You can see flower buds in mid-to-late November, and it will bloom on New Year's Day.

Labor Day

In late December, cut off the stems of chrysanthemums growing on the ground, place them in pots and transfer them to a greenhouse at 15 ℃ to 25 ℃. Pay special attention to proper fertilization and watering. Before long, there will be many new shoots. Leave one or two strong seedlings in each pot. Buds will appear in mid-March, and they will bloom in late April to May.

Party Founding Day

In early February, remove the above-ground parts of last year's chrysanthemums and transfer them to a greenhouse at 15 ℃ to 25 ℃ to allow them to sprout, with one or two seedlings grown in each pot. Starting from early to mid-March, shade the plants at 2 p.m. every day for about one and a half months, with only about eight or nine hours of light a day. Flower buds will appear in late April, and the plants will bloom in early June or July.

National Day

Cultivation by division in spring begins in mid-to-late June, with shading for about one and a half months. Flower buds appear in mid-to-late August, and the flowers bloom around the beginning of October.

Precautions

① When growing seedlings with old roots of chrysanthemum, you need to add an appropriate amount of nitrogen-containing fertilizer and regulate the water content in the flowerpot to help the old roots germinate quickly.

②   When growing chrysanthemums in a greenhouse, you must pay attention to light transmission. If you are using a simple greenhouse, when the light intensity is not enough, it is a good choice to supplement it with electric light. The best distance between ordinary light bulbs and chrysanthemums is about 65 cm. Be careful not to burn them or affect their growth. When using black cloth to block light in a simple darkroom, the standard should be to make it opaque, and also pay attention to ventilation.

③ When the chrysanthemum begins to grow, you must pay attention to cultivation and management so that it can grow healthily. When the chrysanthemum grows to about 45 cm (of course this depends on the variety), you can start the development stage of light exposure.

④   If the chrysanthemums grow too fast and too tall at the beginning, it will be difficult to transfer or shade them. You can control the amount of water and apply fertilizer to promote growth, or pinch the top of the plant during the growing season (multiple times) to make it as short and strong as possible.

⑤   If you block out the light, you cannot interrupt it.

⑥   When the high temperature is around 28 ℃ and the average temperature is below 11 ℃, pay attention to the high temperature dropping and the low temperature rising.

⑦   If chrysanthemums receive less than six hours of sunlight, they will not bloom or will bloom late.
