What You’ll Need
Okay, let’s gather our supplies. Here’s a list of everything you’ll need to successfully grow Heuchera from seed:
* Heuchera Seeds: Purchase high-quality seeds from a reputable source. Fresh seeds are crucial for good germination rates.
* Seed Starting Trays or Pots: I prefer using seed starting trays with individual cells, but small pots work just as well.
* Seed Starting Mix: This is a fine-textured, sterile mix specifically designed for seed germination. Avoid using regular potting soil, as it can be too heavy and may contain pathogens.
* Spray Bottle: For gently misting the seeds and seedlings.
* Clear Plastic Dome or Plastic Wrap: To create a humid environment for germination.
* Grow Lights (Optional but Recommended): Heuchera seeds need light to germinate, so grow lights can be very helpful, especially if you’re starting seeds indoors during the winter.
* Heat Mat (Optional): Heuchera seeds germinate best with slightly warmer soil temperatures.
* Small Labels and a Permanent Marker: To keep track of your different Heuchera varieties.
* Tweezers (Optional): For carefully handling tiny seedlings.
* Well-Draining Potting Mix: For transplanting seedlings into larger containers.
Sowing the Seeds: A Step-by-Step Guide
Now for the fun part! Let’s get those seeds sown.
1. Prepare Your Seed Starting Trays or Pots: Fill your seed starting trays or pots with seed starting mix. Gently tap the trays to settle the mix and remove any air pockets.
2. Moisten the Seed Starting Mix: Use your spray bottle to thoroughly moisten the seed starting mix. It should be damp but not soggy.
3. Sow the Seeds: Heuchera seeds are very tiny, so handle them with care. Sprinkle the seeds evenly over the surface of the seed starting mix. Don’t bury them! Heuchera seeds need light to germinate.
4. Gently Press the Seeds into the Mix: Use your finger or a small tool to gently press the seeds into the surface of the mix. This will ensure good contact between the seeds and the soil.
5. Mist the Seeds: Lightly mist the seeds with water from your spray bottle.
6. Cover the Trays or Pots: Cover the seed starting trays or pots with a clear plastic dome or plastic wrap. This will help to create a humid environment that is essential for germination.
7. Provide Light and Warmth: Place the trays or pots under grow lights or in a bright, indirect light location. If you’re using a heat mat, place it under the trays or pots. The ideal temperature for germination is around 65-70°F (18-21°C).
8. Monitor Moisture Levels: Check the moisture levels daily. The seed starting mix should remain consistently moist but not waterlogged. Mist with water as needed.
9. Be Patient: Heuchera seeds can take anywhere from 14 to 28 days to germinate, so be patient!
Caring for Seedlings
Once your Heuchera seeds have germinated, it’s time to provide them with the care they need to grow into healthy seedlings.
1. Remove the Dome or Plastic Wrap: Once the seedlings start to emerge, gradually remove the plastic dome or plastic wrap over a period of a few days. This will help to acclimate the seedlings to the lower humidity levels of your home.
2. Provide Adequate Light: Heuchera seedlings need plenty of light to grow strong and healthy. If you’re using grow lights, keep them on for 14-16 hours per day. If you’re growing them in a window, choose a bright, indirect light location.
3. Water Carefully: Water the seedlings carefully, allowing the surface of the soil to dry out slightly between waterings. Avoid overwatering, as this can lead to fungal diseases.
4. Fertilize Sparingly: Once the seedlings have developed their first true leaves (the leaves that look like miniature versions of the adult leaves), you can start to fertilize them with a diluted liquid fertilizer. Use a balanced fertilizer (e.g., 10-10-10) diluted to half strength. Fertilize every two weeks.
5. Thin the Seedlings (If Necessary): If you have multiple seedlings growing in the same cell or pot, you may need to thin them out to give the remaining seedlings enough room to grow. Use a small pair of scissors to snip off the weaker seedlings at the soil line.
Transplanting Seedlings
Once your Heuchera seedlings have grown large enough to handle, it’s time to transplant them into larger containers.
1. Choose the Right Potting Mix: Use a well-draining potting mix for transplanting your Heuchera seedlings.
2. Prepare the Containers: Fill the containers with potting mix, leaving about an inch of space at the top.
3. Carefully Remove the Seedlings: Gently remove the seedlings from their seed starting trays or pots. Be careful not to damage the roots. I like to use a small spoon or fork to help lift the seedlings out.
4. Plant the Seedlings: Plant the seedlings in the prepared containers, making sure that the top of the root ball is level with the surface of the potting mix.
5. Water Thoroughly: Water the seedlings thoroughly after transplanting.
6. Provide Shade: Keep the newly transplanted seedlings in a shady location for a few days to help them adjust to their new environment.
7. Gradually Acclimate to Outdoor Conditions: Before planting your Heuchera seedlings in the garden, you’ll need to gradually acclimate them to outdoor conditions. This process is called “hardening off.” Start by placing the seedlings outdoors in a sheltered location for a few hours each day. Gradually increase the amount of time they spend outdoors over a period of a week or two.
Planting in the Garden
Finally, the moment we’ve been waiting for! It’s time to plant your Heuchera seedlings in the garden.
1. Choose the Right Location: Heuchera prefer partial shade, especially in hot climates. They can tolerate full sun in cooler climates. Choose a location with well-draining soil.
2. Prepare the Soil: Amend the soil with compost or other organic matter to improve drainage and fertility.
3. Dig the Planting Holes: Dig planting holes that are slightly larger than the root balls of your Heuchera seedlings.
4. Plant the Seedlings: Gently remove the seedlings from their containers and place them in the planting holes. Make sure that the top of the root ball is level with the surrounding soil.
5. Backfill the Holes: Backfill the holes with soil and gently firm the soil around the base of the plants.
6. Water Thoroughly: Water the plants thoroughly after planting.
7. Mulch: Apply a layer of mulch around the base of the plants to help retain moisture and suppress weeds.
Ongoing Care
Once your Heuchera are planted in the garden, they’re relatively low-maintenance. Here are a few tips for keeping them healthy and happy:
* Watering: Water regularly, especially during dry periods. Heuchera prefer consistently moist soil, but avoid overwatering.
* Fertilizing: Fertilize in the spring with a balanced fertilizer.
* Deadheading: Remove spent flower stalks to encourage more blooms.
* Dividing: Divide your Heuchera every few years to prevent them from becoming overcrowded.
* Pest and Disease Control:

Frequently Asked Questions (FAQs)
What is the best time of year to start Heuchera seeds?
The ideal time to start Heuchera seeds is typically in late winter or early spring, about 8-10 weeks before the last expected frost. This allows the seedlings enough time to develop before being transplanted outdoors in the spring. Starting them indoors gives them a head start and protects them from harsh weather conditions. However, you can also start them in late summer or early fall for transplanting the following spring. Just be sure to provide adequate protection during the winter months.
Do Heuchera seeds need light to germinate?
Yes, Heuchera seeds require light to germinate. This means you should not bury them deeply in the soil. Instead, gently press them onto the surface of the seed-starting mix and lightly mist with water. Covering the seed tray with a clear plastic dome or bag can help maintain humidity, but be sure to remove it periodically to allow for air circulation and prevent fungal growth.
How long does it take for Heuchera seeds to germinate?
Germination times can vary depending on the variety of Heuchera and the environmental conditions, but generally, you can expect to see seedlings emerge within 14-21 days. Keep the seed-starting mix consistently moist and maintain a temperature of around 65-70°F (18-21°C) to encourage germination. Be patient, as some seeds may take longer to germinate than others.
What type of soil is best for growing Heuchera seedlings?
A well-draining, sterile seed-starting mix is essential for growing healthy Heuchera seedlings. Avoid using garden soil, as it may contain pathogens or weed seeds that can harm the delicate seedlings. A mix of peat moss, perlite, and vermiculite is a good option. You can also purchase pre-made seed-starting mixes from your local garden center.
How often should I water Heuchera seedlings?
Heuchera seedlings need consistent moisture, but they should not be waterlogged. Water them gently whenever the top of the soil feels dry to the touch. Use a spray bottle or a watering can with a fine rose to avoid disturbing the delicate seedlings. Overwatering can lead to fungal diseases, so be sure to provide adequate drainage.
When can I transplant Heuchera seedlings outdoors?
You can transplant Heuchera seedlings outdoors once they have developed several sets of true leaves and the danger of frost has passed. Harden off the seedlings by gradually exposing them to outdoor conditions for a week or two before transplanting. Choose a location with well-draining soil and partial shade. Heuchera plants prefer morning sun and afternoon shade, especially in hot climates.
What are some common problems when growing Heuchera from seeds?
Some common problems include damping off (a fungal disease that causes seedlings to collapse), overwatering, and insufficient light. To prevent damping off, use a sterile seed-starting mix and avoid overwatering. Provide adequate light by placing the seedlings under grow lights or in a sunny window. If you notice any signs of fungal disease, treat the seedlings with a fungicide.
