When to plant delphinium seeds

Harvesting delphinium seeds

Before sowing delphiniums, the seeds must be harvested first. Generally, the fruits of delphiniums mature between August and September. The fruits contain small seeds.

After the fruits of delphinium are ripe, they will crack and the seeds will easily fall out, so they need to be harvested in time. However, because delphiniums bloom first and their fruits mature first, the seeds need to be harvested in batches.

The harvested seeds of delphinium need to be stored, usually by drying them and placing them in a cool and dry place indoors.

When to plant delphinium seeds

Delphinium can be sown in batches, so that you can see the flowers of delphinium frequently. When sowing delphiniums, it can usually be done in spring or autumn. However, in places where the temperature is relatively high in summer, sowing should be avoided during the summer.

Basically, when sowing delphiniums, seedlings need to be raised in advance. Start sowing in late August. By October, the delphinium seeds will germinate and grow 2-4 true leaves, then they can be transplanted. Pay attention to keeping warm and providing additional light in winter, and you can plant them in March of the following year. In this way, delphinium can bloom from May to July.
