When to Plant Delphinium Seeds
Timing is everything! For the best results, start your Delphinium seeds indoors about 8-10 weeks before the last frost of spring. If you’re feeling brave, you can also direct sow them outdoors after the last frost when the soil has warmed up. Just be sure to avoid planting too early—those late frosts can be sneaky!
Where to Plant Delphinium Seeds
Delphiniums thrive in full sun but appreciate a little afternoon shade, especially in hotter climates. Choose a spot with rich, well-draining soil that can keep them happy. These tall beauties can grow up to 6 feet, so plant them at the back of your flower beds or borders where they can strut their stuff without blocking the view of their shorter floral friends.
How to Plant Delphinium Seeds
Get Ready to Sow: Whether you’re starting indoors or outdoors, sprinkle those seeds onto the soil surface and give them a gentle press. Delphinium seeds like a little light to germinate, so don’t bury them too deep—just a light dusting of soil will do!
Patience is Key: If you’re starting indoors, keep your little seedlings cozy at around 65-70°F. Germination can take anywhere from 2 to 4 weeks, so sit tight! Once they’ve sprouted a few leaves, thin them out to give each plant a bit of breathing room—aim for about 12-18 inches apart.
How to Care for Delphinium
Delphiniums enjoy a regular drink, especially during dry spells, but don’t drown them! Water at the base to keep those blooms dry and healthy. They love to be fed, so give them a balanced fertilizer every 4-6 weeks to promote robust growth and vibrant flowers.
Once they bloom, keep an eye on spent flowers and deadhead them to encourage a second wave of blooms. And if your Delphiniums get a little too tall and wobbly, don’t hesitate to stake them for support—they’ll thank you by standing tall and proud!
With a little love and attention, your Delphiniums will transform your garden into a stunning floral masterpiece, making you the envy of the neighborhood!
