Sowing technique of potted blue chrysanthemum

Especially like this kind of herbal floret, today I know that she also has a beautiful name, blue chrysanthemum. Blue eye chrysanthemum alias African daisy, big flower blue eye chrysanthemum. Semi-shrub or perennial perennial herb with solitary head, tomentose involucre, white ligulate flowers, lilac abaxially, blue-purple disk. Blue-eye chrysanthemum achenes are furrowed and villous. Plants highly 20--1500px, basal leaves clustered, cauline leaves alternate, usually pinnatifid.

Blue chrysanthemum can be used in flower border, or cut flowers, water culture period is longer. Can also be potted, small Jasper-like beauty. It is usually propagated by sowing or cutting. Spring sowing takes place in March and autumn sowing takes place in September. The land with sufficient sunshine should be selected for planting, and half of loam and rotten leaf soil should be used in potted plants, and an appropriate amount of river sand should be added. Next, I would like to introduce the sowing method of blue chrysanthemum.

1. Prepare to sow soil.

2. The soil used for sowing small seeds had better be screened first, then use the leaky fruit basket commonly used at home, put the fine soil under the sun, and first use the screened branches to cover the bottom, because there are holes the size of small fingers at the bottom of the seedling tray. Fine soil is easy to lose, just can use these large guys, and then put the fine soil until the hole is filled. Fine soil is placed on the surface in order to better infiltrate with small seeds and facilitate germination. In fact, sowing soil with Cuiyun is not a big problem without sieving. Cuiyun's sowing soil itself is also relatively fine.

3. The humidity of the sowing soil should be appropriate, and it is appropriate to hold the hand into a ball and loosen the hand. Some people may ask, isn't it the same for seeds to be buried and then sprayed with water? It is really different. Everyone who has used it knows that the cultivated soil is very light, and the wettability of the dry soil is very poor. After spraying water, it floats, and it is very difficult to wet, so it is necessary to pour less water to stir and mix the soil.

4. Put the thick soil left after sifting on the lower part of the seedling plate hole and the fine soil on top.

5. Spray water to make the soil surface fully moist. If you have water on your hands, you can spray it with its 500 times dilution solution, which is conducive to germination.

6. Sow seeds with toothpicks after dipping them in water, one at a time, and place them in the center of the hole. The coated seeds had better press slightly into the soil. Small seeds are generally light-loving, do not need to cover the soil, it is best to have a hole, after sowing, put the seedling plate into the bottom basin with water, let the water slowly infiltrate. Large seeds dislike light, the seeds should be covered with soil, cover the seeds, and it is best to put them in a cool, dark place before germination. The dwarf hates light, so the plastic film can be covered with black film. Seedling plate is only suitable for small seed sowing, such as geranium, blue chrysanthemum, golden lotus and so on had better be sowed directly in the small seedling basin.

7. Spray water after sowing until the soil is completely wet, and then cover it with plastic film. Do not remove the plastic film before germination, it is best to spray water once a day, and then take off the plastic film after germination to give the seedlings normal light. Make your own small family greenhouse. Put the seedling tray in such a small family greenhouse. Cover the lid until it germinates. The greenhouse is placed in a cool place when the temperature is high, and when the temperature is low, you can bask in the sun during the day and take it back to the house at night. It should be noted that once seedlings sprout, you must let them bask in the sun, otherwise a day or two may be in vain. When the seedlings are almost ready, take out the seedling plate and let the seedlings receive sunshine in a well-ventilated place. It is best to let the soil have a dry-wet cycle in a day or two. Blue chrysanthemum sowed in a large basin, separated by a 2~3CM, and then moved out after germination, a pot of a seedling. Seedlings with small seeds are generally more resistant to transplantation and can be moved when the seedlings are slightly larger. It is best to bring some soil when transplanting and pay attention to proper shading for a few days after transplanting.

8. After budding, it should be ventilated and sunny, and the soil should not always be wetted, otherwise the stem will wither easily. The first summer rain was reported, and the blue chrysanthemum also appeared small yellow buds. It doesn't matter if a large seed is a single direct seeding, but it is best if it is mixed with multiple seeds.
