Culture methods of potted Chrysanthemum

The culture methods of chrysanthemum generally adopt root propagation, cuttage propagation and striping propagation. Split root propagation should be carried out from April to May; cutting propagation needs to be cut off as diseases and insects, robust branches as cuttings, the soil should not be too wet when cutting, and the most suitable cutting depth is 5mi 7cm. Striping propagation is most suitable for overcast and rainy days, in the first time in Lesser Heat (before and after, the chrysanthemum branches are crushed first, every 10cm is beaten to the top with wet mud cover, so that new branches are pulled out from the axils of the sharp leaves, and the second time in Greater Heat (before and after, the new pumping technique is overwhelmed, the method is the same as the first time, and the rotten human feces are applied once, and the top is hit in the End of Heat.

1. Temperature:

Potted chrysanthemums are suitable for growth at about 21 degrees Celsius, while ornamental chrysanthemums are cold-resistant and can survive the winter safely at about 5 degrees Celsius. But not resistant to heat, the temperature will grow slowly when the temperature is above 32 degrees Celsius.

2. Lighting:

Chrysanthemum is a typical short-day flower, which forms flower bud and blossoms only when the sunshine is short every day. In the case of long sunshine, only long stems and leaves, can not form flower buds. In general, 14.5 hours of sunshine per day is required during vegetative growth and 12 hours per day during flower bud differentiation.

3. Soil:

Ornamental chrysanthemum has a wide adaptability to the acidity and basicity of soil. It can grow in slightly acidic to slightly alkaline soils with a ph between 5.5 and 7.0. Potted chrysanthemum to choose a suitable pot soil, pot soil to choose loose, fertile sandy soil.

4. Moisture:

Ornamental chrysanthemums have a large demand for water, but they are afraid of stagnant water. Especially during the period of vegetative growth, the growth rate is fast and the water demand is large. It's easy to be short of water. Water it frequently. But be careful not to accumulate water.

5. Fertilization:

When fertilizing, you must sprinkle the fertilizer first, and then pour the water thoroughly, so that the fertilizer can fully seep into the root system of the chrysanthemum, so that it can be absorbed by the chrysanthemum.

6. Picking the heart and soothing the bud:

When the chrysanthemum plant grows to more than 10 centimeters high, it begins to pick the heart. When picking the heart, only 4-5 leaves were left at the base of the plant, and all the upper leaves were removed. When the leaves grow out of new branches with 5-6 leaves, pick the heart again, so that the plant retains 4-7 main branches, and the branches and buds that grow later should be removed in time.

So how do we take care of chrysanthemums in this season?

(1) reasonable watering

Whether watering is reasonable or not is important to the growth of chrysanthemum. It should be watered at the right time. Chrysanthemums must be well watered before they can grow well and have large and colorful flowers. In particular, more water is needed after the emergence of buds.

(2) appropriate amount of fertilization

Before fertilizing, the soil should be loosened, not watered, and the fertilizer solution should be poured when the basin soil is dry, and the fertilizer and water must not be stained on the branches and leaves when fertilizing, otherwise the leaves will wither and yellow. after fertilization, spray water should be sprayed to the seedlings in time to wash away the contaminated liquid on the leaves.

(3) careful pruning

In order to make the chrysanthemum grow evenly and the branches erect, pillars are often set up. The pillar is often made of fine bamboo or Reed, and the chrysanthemum branch is tied to the pillar with a string, and each branch is provided with a pillar. (after the flower bud opens, the white and green flower varieties should be moved to the shade, or take other measures to protect the light, so as to keep the flower color bright green, otherwise the flower color is not correct, when blooming the dark flower bud, strong light is needed, and some organic liquid fertilizer is added to make the flower color rich. )

(4) Pest control

There are many diseases and insect pests in potted chrysanthemum in autumn. The initial stage of the disease with 1% Bordeaux solution or 50% Dyson zinc powder plus 1200 times water spray, once a week, spray 3 times.
