2.  Choosing Your Calendula Seeds

When selecting your calendula seeds, consider checking out Gardeners Basics for various options.  Once you've picked your seeds, it's time to sow calendula and transform your garden into an orange paradise.

3.  Timing Is Everything: When to Sow Calendula Seeds

To grow calendula from seed, start sowing seeds indoors about 6-8 weeks before the last frost date.  This gives your calendula seedlings enough time to grow and establish themselves before transplanting them outdoors.

4.  Sowing Seeds Indoors: The Perfect Environment

To sow calendula seeds indoors, follow these simple steps:

  1. Choose a container: Select a container with good drainages, such as seed trays or peat pots.  You don't want your seeds drowning in a pool of water.
  2. Prepare the soil: Fill the container with a well-draining potting mix.  Calendula plants prefer well-drained soil to prevent root rot.
  3. Sow the seeds: Plant the calendula seeds about ¼-inch deep and 2 inches apart.  They don't need to be buried too deep to germinate.
  4. Maintain the temperature: Keep the soil temperature between 65-75°F (18-24°C) for optimal germination.  You can use a heating mat if necessary.
  5. Monitor the moisture: Ensure the soil remains consistently moist but not soggy.  Calendula seeds typically germinate within 10-14 days.

5.  Transplanting Calendula Seedlings

Once your calendula seedlings have developed 2-4 true leaves, it's time to move them outside.  But first, let's get them acclimated to their new environment.

  1. Harden off the seedlings: Gradually expose your calendula seedlings to outdoor conditions over 7-10 days.  Start with a couple of hours in a sheltered location and gradually increase the time spent outside.
  2. Choose the perfect spot: Calendula plants thrive in full sun to partial shade.  They're not picky, but they do love soaking up some rays.
  3. Prepare the soil: Ensure your garden has good drainage, like indoor potting mixes.  If your soil is heavy or clay-like, amend it with compost or organic matter to improve drainage.
  4. Plant the seedlings: Space your calendula plants about 12-18 inches apart for proper air circulation and growth.  Dig a hole slightly larger than the root ball, place the seedling in the hole, and gently cover the roots with soil.
  5. Water and watch them grow: Water your transplanted calendula seedlings well to help them settle in.  Continue watering them as needed to keep the soil moist but not waterlogged.

6.  Direct Sowing Calendula Seeds OutdoorYouou can also sow calendula seeds directly in your garden after the last frost date.  Just follow these steps:

  1. Choose your spot: Find a location with full sun to partial shade and well-drained soil.
  2. Prepare the soil: Loosen the dirt to a depth of about 6-8 inches and mix in some compost or organic matter to improve drainage and fertility.
  3. Sow the seeds: Plant calendula seeds about ¼-inch deep and 2 inches apart in rows or clusters.
  4. Thin the seedlings: Once the calendula seedlings have developed 2-4 true leaves, thin them to a final spacing of 12-18 inches apart.

7.  Caring for Your Calendula Plants

Growing calendula plants is a breeze if you follow these simple tips:

  1. Watering: Water your calendula plants regularly to maintain consistent soil moisture, but avoid overwatering to prevent root rot.
  2. Fertilizing: Calendula plants aren't heavy feeders, but they appreciate a balanced, slow-release fertilizer or a side dressing of compost to keep them happy and healthy.
  3. Deadheading: Remove spent calendula flowers to encourage continuous blooming and prevent self-seeding.  This will keep your garden looking fresh and vibrant throughout the season.
  4. Pest control: Calendula plants may attract aphids or whiteflies.  Keep an eye out for these pests and use insecticidal soap or neem oil to control them if necessary.

8.  Harvesting and Using Calendula Flowers

Harvest your calendula flowers once fully open, ideally in the morning after the dew has dried.  You can use the fresh calendula petals in salads, teas, or skincare products.  To dry calendula petals, spread them out in a single layer on a screen or tray in a well-ventilated area, away from direct sunlight.  Once dried, store them in an airtight container for later use.

In Conclusion

Growing calendula from seed is a fun and rewarding experience.  These stunning orange flowers will add color to your gardens and serve as an excellent companion plant, attracting pollinators and providing numerous health benefits.  Follow this step-by-step guide, and soon you'll have a garden filled with thriving calendula plants that even the most seasoned gardener would be proud of.
