When does it bloom

The sowing of Delphinium can be divided into spring sowing and autumn sowing. The flowering period of Delphinium planted in spring is from July to August, and the flowering period of autumn sowing is from March to May of the next year

Applying nitrogen fertilizer before flowering, applying more phosphorus and potassium fertilizer after flowering and watering appropriately, and increasing lighting after October can promote early flowering. When the plant grows to 20 cm high, erect the scaffold and stretch the net to prevent lodging

How to maintain flowering

Watering: Delphinium likes a humid growth environment. In particular, the pot soil should be avoided from drying during flowering to ensure the supply of water. Flowers can bloom, bright and beautiful

Fertilization: nitrogen fertilizer should be selected for top dressing before flowering, so as to ensure that the flowers are plump and bright. More phosphorus and potassium fertilizer should be applied after chemical transformation to ensure the normal growth of plants and avoid overgrowth and lodging. Fertilizer can be applied 1-3 times a month

Pest control: when Delphinium is attracting bees and butterflies during flowering, pay attention to small animals such as bees and butterflies to bring bacteria or insect eggs to the plant for timely inspection. In case of aphids and night moths, they should be cleaned up in time and sprayed with chemicals in time

Shaping and maintenance: only when the main stem is upright can it produce huge and beautiful flowers. It is necessary to avoid breaking the main stem. A branch or bamboo pole can be inserted into the flower pot as a traction to help the main stem with high pressure
