Cultivation methods and precautions of delphinium

How to grow delphinium

Light and temperature

Delphinium prefers a cool and well-lit growing environment. During the breeding process, it is necessary to ensure sufficient light and keep the temperature between 15℃ and 25℃. Because delphinium likes a cooler climate and can withstand cold, the breeding temperature should not be too high.

soil

When growing delphiniums, you can use sandy soil with good drainage. Generally, it is best to add a little base fertilizer to the soil to keep the soil fertile.

Water and fertilizer management

Watering should be moderate. Delphinium prefers a drier growing environment and generally does not require too much water. Drainage is also required during the rainy season. In addition to applying some base fertilizer before planting, you can also apply top dressing during the growth period. Top dressing is generally based on nitrogen fertilizer.

Reproduction method

Delphinium can be propagated by cuttings, division and sowing. Division is generally carried out in spring and autumn, cuttings are mainly carried out in spring, and sowing is mostly carried out in March and April.
