4. Dwarfing and erection

After changing the soil in spring, 0.5% paclobutrazol was applied every 2 weeks to control the height of the plant. When the plant is 20 cm high, a support net can be set up to prevent lodging. The seeds should be collected in time after maturity to avoid fruit cracking after maturity.

5. Sunshine

Swallows like sunny environments, especially during flowering. It is not necessary when it is hot in summer, but you can sprinkle more water to cool down. Swift grass potted plants need sunshade at noon to strengthen ventilation. Water control is needed in winter, giving sunshine or greenhouse lighting during the day can also blossom ahead of time.

The seeds and cuttings for the propagation of delphinium can be carried out in spring and autumn, usually once every 2-3 years, and it is better to sow in the middle of September in autumn, increase lighting after entering October, and blossom in May and July the following year. The optimum temperature for seed germination is 15 degrees, and the optimum temperature for growing period is 20-25 degrees during the day and 3-15 degrees at night.

7. Administration and Management

Swallow grass in the summer high temperature to prevent moisture, the plant is not too dense, found that withered branches are cut off in time, maintain good ventilation, light and ventilation, otherwise it is appropriate to get sick and bacterial damage.

5. Height control: paclobutrazol was used to control the height of the plant after changing pots, and 0.5% paclobutrazol was applied every 2 weeks.

6. Seed collection: the seed of delphinium should be collected in time to avoid fruit cracking after ripening.

7. Diseases: Swift grass often has black spot, root neck rot and chrysanthemum leaf blight that damage leaves, flower buds and stems. It can be sprayed with 30% topiramine wettable powder 500 times.

8. Insect pests: delphinia pests are often harmed by aphids and night eggs, which are sprayed with 2000 times of deworming essential oil.
