How to Save Dahlia Seeds: A Comprehensive Guide
How to Save Dahlia Seeds?
To save dahlia seeds, start by collecting the seed pods after the flowers have dried out.
The seeds are brown to black in color and can be found inside the pods.
Once collected, plant the seeds in moist seed starting mix, about ⅛ inch deep, and keep them in an environment with a temperature of 70-75⁰F for germination.
The seedlings will emerge in 7-14 days, and it’s important to keep them close to a light source for adequate light.
Bottom watering is recommended for the seedlings.
After 100-120 days, the dahlias will bloom.
If you want to save tubers by the end of summer, cut the stalks down to soil level and protect them during winter by either leaving them in the ground or lifting and storing them undercover.

Did You Know?
1. The process of saving Dahlia seeds involves waiting until the flower has completely finished blooming and the petals have fallen off. It is then that the Dahlia produces seed pods, known as “hips,” which can be collected and saved for future planting.
2. Dahlia seeds are not true to their parent plants, meaning that the seeds will not produce an exact replica of the original plant. Instead, growing Dahlia plants from seeds often results in a variety of unique colors, shapes, and sizes, making each new plant a delightful surprise.
3. Dahlia seeds require a process called “stratification” to improve germination rates. This involves placing the seeds in a moist environment at a cold temperature, usually in the refrigerator, for a period of four to six weeks. Stratification mimics the natural winter conditions that Dahlia seeds would typically experience before sprouting in the spring.
4. To increase the chances of successful germination, it is recommended to soak Dahlia seeds in water for 24 to 48 hours before planting. This helps to soften the outer seed coat, allowing water to penetrate and begin the germination process more easily.
5. While Dahlia seeds can certainly be saved and successfully grown, they are not the most common method of propagating these flowers. Due to the inconsistent results and the time it takes for a plant to reach maturity from seed, many gardeners prefer to propagate Dahlias through tubers or cuttings, as these methods produce more reliable, true-to-type plants in a shorter time frame.
Determining The Right Time To Start Dahlia Seeds Indoors
When it comes to starting dahlias from seeds, timing is crucial. To ensure successful germination and healthy growth, you need to know the last expected frost date in your area. Counting back 6-8 weeks from the last frost date will give you the ideal time to start Dahlia seeds indoors. This allows enough time for the seedlings to establish before transplanting them outside.
Keep in mind that dahlias from seeds take around 100-120 days to bloom. Thus, if you want to enjoy the vibrant blooms of dahlias during the summer, it is essential to plan ahead and start the seeds at the appropriate time.
Proper Techniques For Germinating Dahlia Seeds
Germinating dahlia seeds requires proper technique to ensure successful growth. Begin by planting the seeds in moist seed starting mix, approximately ⅛ inch deep. The ideal temperature for germination is between 70-75⁰F, providing optimal conditions for seedling emergence within 7-14 days after planting.
To ensure adequate light, keep the seedling tray close to a light source. Bottom watering is recommended to promote healthy growth. This involves placing the seedling tray in a shallow container filled with water for a few minutes, allowing the seedlings to absorb water through the drainage holes at the bottom of the tray.
Collecting Dahlia Seed Pods For Future Planting
Dahlias produce beautiful flowers that eventually turn into seed pods, housing their seeds. To save dahlia seeds for future planting, you need to collect these seed pods. Wait until the flowers have completely dried out before collecting the seed pods. The seeds are usually brown to black in color and can be found inside the seed pods.
To collect the seed pods, carefully remove them from the dried flowers. Place the pods in a paper bag or envelope, ensuring they are well-labeled. Storing them in a cool, dry place until the next planting season will help maintain their viability.
Essential Steps For Potting And Hardening Off Dahlia Seedlings
As your dahlia seedlings mature, they may need to be potted up if they are not yet ready for planting in the garden. Use well-draining soil and provide appropriate-sized containers to ensure the seedlings have enough space for growth. Harden off the seedlings before planting them outside to acclimate them to outdoor conditions gradually.
The hardening off process should take place on calm days, avoiding strong winds that may damage the delicate seedlings. It involves gradually exposing the seedlings to outdoor conditions, starting with a few hours outside and gradually increasing the time each day. This process helps the seedlings adjust to temperature changes, sunlight, and wind, ensuring they can thrive when planted in the garden.
- Use well-draining soil
- Provide appropriate-sized containers
- Harden off the seedlings gradually before planting them outside
- Avoid strong winds during the hardening off process
- Gradually increase the time spent outside each day during hardening off process.
The Best Conditions For Growing Dahlias From Seeds
When it comes to growing dahlias from seeds, providing the right conditions is crucial for their success. Dahlias thrive in full sun and well-draining soil. Before planting, enrich the soil with compost or well-rotted manure to improve its fertility and drainage.
Spacing between dahlias varies depending on the variety, so make sure to follow the instructions provided for the specific variety you are growing. This will ensure adequate airflow around the plants, reducing the risk of disease and promoting healthy growth.
Regular watering and fertilization throughout the growing season are essential to support the development of strong and vibrant dahlia plants.
- Provide full sun and well-draining soil for dahlias.
- Enrich the soil with compost or well-rotted manure before planting.
- Follow spacing instructions for the specific variety.
- Regularly water and fertilize for strong and vibrant plants.

Overwintering Dahlia Tubers: Proper Storage And Maintenance
At the end of summer, dahlias grown from seeds will produce tubers. If you wish to preserve the tubers for the next growing season, proper storage is essential. The method you choose – leaving them in the ground or lifting them and storing them undercover – depends on your specific climate and garden conditions.
If you decide to leave the dahlias in the ground, provide them with winter protection by cutting the stalks down to soil level. Applying mulch or other protective coverings can help insulate the tubers from harsh winter conditions.
In colder climates, lifting the tubers and storing them undercover is advised. Wait until the tops have been frosted before lifting the dahlias. Knock off excess soil and scoop out loose soil between the tubers, taking care not to damage them. Do not clean the tubers under a tap at this time of year. Instead, let them dry upside down for a couple of weeks before storing.
Store the dried tubers in a cool, frost-free place, regularly inspecting them for any signs of rotting during the winter months. Proper storage and maintenance ensure that your dahlias will be ready for planting again in the following growing season, allowing you to enjoy their beautiful blooms year after year.
Frequently Asked Questions
Can you keep dahlias grown from seed?
Yes, dahlias grown from seed can be kept and cultivated successfully. While tubers are commonly used to propagate dahlias due to their quicker and more reliable growth, growing dahlias from seed is also a viable option. To do so, dahlia seeds should be planted between the months of February and April, indoors or undercover. Ensuring the seeds are sown 0.5cm deep in trays of moist compost will provide them with the optimal conditions for germination and subsequent growth. With proper care and nurturing, dahlias grown from seed can flourish and become beautiful additions to any garden.
What do dahlia seeds look like?
Dahlia seeds present themselves as small, elongated pods with a rich color palette ranging from brown to black. Typically measuring approximately half an inch in length, these slender pods can be effortlessly split open to reveal the tiny yet intriguing seeds within. Once the dahlia flowers have completed their blooming cycle and dried out, these distinct seed pods can be gathered and collected for future cultivation endeavors.
Do dahlias reseed themselves?
Yes, dahlias have the ability to reseed themselves through their dual reproductive methods. Once pollinated and properly ripened, the flowers of dahlias produce seeds that can give rise to new plants.
