Note: when choosing soil, it is best not to choose too sticky soil, this kind of soil is very disadvantageous to the growth of delphinium, it will make it difficult to absorb nutrients, resulting in yellowing and wilting of leaves.

two。 Seed requirement

About how to plant delphinium, the choice of seeds is also a very important step. The seeds of delphinium generally mature around June every year, when we can harvest the seeds, remember to select mature seeds when collecting seeds, and then store them until August-September to sow them.

Note: after taking out the seeds from July to August, it is best to soak the seeds of delphinium in warm water for 12-24 hours, and then take them out and sow them when they begin to absorb water and swell, so that the seeds can germinate quickly.

3. Planting method

About how to plant swallows, in fact, the method is very simple. First of all, we should mix the seeds and fine sand evenly on the soil surface, and then cover the soil with about 1-2cm for watering. When watering, the seeds will germinate in about 7-12 days.

Planting methods and matters needing attention of delphinium

The flower shape of swallows is similar to that of swallows, and swallows are widely planted, which are common in grasslands and hillsides. Some friends will plant delphinium in pots, and then Xiaoqi will share the planting methods and precautions of delphinium.

First, the planting method of delphinium

1. Soil: slightly acidic sandy soil with rich humus, the pH value is best controlled at 5.5-6. Keep the soil moist and not easy to accumulate water. 6 to 9 weeks after germination, each seedling can be transplanted into a flowerpot with a diameter of 9 to 10 cm, or every 3 seedlings can be transplanted into a large pot with a diameter of 13 to 15 cm. Don't plant the plant too deep when transplanting.

2. Lighting: swallows need to receive enough sunlight to promote plant growth, especially in winter, tolerate certain shades, avoid strong light in summer and put them in semi-shady places. Like cool weather, the best growth temperature is between 20-25 ℃ during the day and 3-15 ℃ at night.

3. Watering: swallow grass likes to be moist and resistant to drought. When watering, it should be watered at once, dry, and the amount of water should be slightly increased during flowering, not too dry. When changing the basin, the base fertilizer needs to add dry manure, and in other periods, fertilizer should be applied according to the growth of the plant, generally applying cooked cake fertilizer and water 1 to 3 times a month.

II. Matters needing attention in the cultivation of delphinium

Delphinium needs a sunny and cool growth environment. It can tolerate both cold and drought, but it is not resistant to high temperature and moisture, and the requirement for soil is not very high. It can be sown in spring or autumn, and if sown in autumn, it must be in mid-September. The soil must be kept moist after sowing. The easiest way is to cover some grass and gradually remove the mulch after emergence. When Swift grass grows 2 true leaves, transplant it in a small basin with soil, and then change the pot once after the seedlings grow up.

Swallow watering should be dry and wet, and a little more water should be properly watered during the flowering period to avoid excessive dryness of the soil. Dry manure was applied as base fertilizer when changing pots, and then rotten cake fertilizer and water was applied one to three times a month according to the growth situation. After changing the basin, paclobutrazol was used to control the height of the plant, and 0.5% paclobutrazol was applied every 2 weeks. The seeds should be collected in time to avoid fruit cracking after ripening.

The above is the planting methods of delphinium and points for attention to share, hoping to be helpful to the friends who cultivate delphinium.

First, a brief introduction to delphinium

Swallow grass, also known as pigeon flower, Baibu grass, dried bird grass, etc., swallow grass flower shape is beautiful, similar to flying swallow, high ornamental value. Delphinium is a kind of taproot flower, which is better for direct seeding and is not resistant to transplanting. To plant delphinium, you can first sow the seeds on the sowing plate, and then hold the pot in the 10cm basin. During the growing period, the swallows were fertilized once every semimonthly, and the phosphorus and potassium fertilizers were applied 2 or 3 times before flowering. Keeping the soil moisture during the flowering period can prolong the flowering period. After ripening, the fruit of Swift grass will crack and scatter the seeds, so the seeds should be collected in time. There are many seeds in the fruit, and the seeds are small, which are collected and dried and stored in a cool and dry place in the room. In order to make delphinium multiseason blossom can be sown by stages, but the southern cultivation should stagger the flowering period in midsummer and hot days.

The perennial delphinium of the same species can also be propagated by cutting and ramet. The cuttings of delphinium are raised in spring and picked and planted in wet sand beds or sand tables. Ramet can be carried out in spring and autumn, the seedlings germinated around the old plant, dug up with roots, divided into small plants, if the spring ramet can blossom in the same year.
