Planting and maintenance of delphinium

Delphinium is also called pigeon flower, chicken claw lotus, thousand bird flower, and lily of the valley. It is named because its appearance resembles a swallow. When delphiniums bloom, the flowers form clusters and are very ornamental. Here is an introduction to the planting and maintenance of delphiniums.

1. Soil

For planting delphinium, it is best to use slightly acidic sandy soil with humus fertility. The pH value should be controlled at 5.5-6.0. Keep the soil moist and not prone to waterlogging.

2. Planting

Delphiniums can be sown in spring and autumn, but if sown in autumn, it must be done in mid-September. After sowing delphinium, the soil must be kept moist. A simple way is to cover it with some grass and then gradually remove the covering after the seedlings emerge. When the delphinium grows two true leaves, it needs to be transplanted into a small pot with soil, and then the pot should be changed again after the seedling grows up.

3. Lighting

Delphinium needs to receive sufficient sunlight to promote plant growth, especially in winter. It can tolerate a certain amount of shade. In summer, it should avoid strong light and be placed in a semi-shaded place.

4. Watering

Delphinium likes moisture and is also drought-resistant. When watering, water it sufficiently at one time and water it again when it is dry. Increase the amount of watering slightly during the flowering period and do not let the soil be too dry.

5. Fertilization

During the growing period of delphinium, apply fertilizer once every half month, and apply phosphorus and potassium fertilizers 2-3 times before flowering. Keeping the soil moist during the delphinium flowering period can extend the flowering period. Depending on the growth condition of delphinium, apply cake fertilizer and water 1-3 times a month.

6. Height control

After repotting the delphinium, use paclobutrazol to control the height of the plant. The specific method is to apply 0.5% paclobutrazol once every 2 weeks.

7. Seed collection

Delphinium seeds must be collected in time to avoid the fruits cracking after they mature.
