Agastache, also known as hyssop or hummingbird mint, is indeed quite easy to grow from seed. Whether you choose to plant the seeds in spring or fall, the process is relatively straightforward and can be a rewarding experience for both novice and experienced gardeners.
When it comes to planting Agastache seeds, you have a couple of options. You can either sow them directly into the garden soil or start them indoors and later transplant them outside. Both methods have their advantages, so it ultimately depends on your preference and the resources you have available.
If you decide to sow the seeds directly into the garden, it’s best to wait until the soil has warmed up in the spring. Agastache prefers well-draining soil, so make sure to prepare the planting area by loosening the soil and removing any weeds or debris. You can then sprinkle the seeds over the prepared area and lightly press them into the soil. It’s important not to bury the seeds too deep, as they require light to germinate.
To increase the chances of successful germination, you can cover the seeded area with a thin layer of fine soil or vermiculite. This will help retain moisture and provide a protective barrier for the seeds. Water the area gently but thoroughly, keeping the soil consistently damp until the seeds germinate.
If you choose to start the Agastache seeds indoors, you can do so about 6-8 weeks before the last frost date in your area. Fill seed trays or pots with a well-draining seed starting mix and lightly press the seeds into the soil. Again, avoid burying them too deep. Place the trays or pots in a warm and well-lit area, such as a sunny windowsill or under grow lights.
Keep the soil consistently moist but not overly saturated. Germination typically takes around 10-14 days, but it can vary depending on the specific variety of Agastache you are growing.
Once the seedlings have developed a few sets of true leaves and the danger of frost has passed, you can transplant them into the garden. Choose a location that receives full sun to partial shade and has well-draining soil. Dig a hole slightly larger than the root ball of the seedling and gently place it in, making sure the top of the root ball is level with the surrounding soil. Space the plants according to the recommended spacing for the specific Agastache variety you are growing.
Water the transplanted seedlings thoroughly and continue to keep the soil consistently moist until they become established. Agastache plants are generally drought-tolerant once established, but they will benefit from regular watering during dry spells.
Agastache is a relatively low-maintenance plant and does well in a variety of climates. It is known for its attractive foliage and vibrant flowers, which also attract pollinators like bees and hummingbirds. Deadheading the spent blooms can encourage a longer blooming period and prevent self-seeding, although some gardeners may choose to leave the seed heads for winter interest.
Growing Agastache from seed is a rewarding and relatively easy process. Whether you choose to sow them directly into the garden or start them indoors, with a little care and attention, you can enjoy beautiful and fragrant Agastache plants in your garden.
