When it comes to growing dahlias, there are multiple methods to choose from. While many gardeners prefer to grow dahlias from tubers, it is not the only option. Let’s explore the different ways you can grow dahlias and the advantages of each method.
1. Growing from Tubers:
– Tubers are the most common way to propagate dahlias. They are essentially swollen underground stems that store nutrients for the plant.
– Tubers can be purchased from a garden center or online, usually in late winter or early spring.
– To start growing from tubers, pot them up in well-draining soil in late March or early April. Place the pots in a warm and bright location indoors.
– As the tubers sprout and develop shoots, provide them with regular watering and care.
– Once all risk of frost has passed, usually in May, you can transplant the tubers into the garden. Choose a sunny spot with well-draining soil and space them according to the variety’s requirements.
– Tubers can be lifted and stored over winter, allowing you to grow dahlias year after year.
2. Rooted Cuttings:
– Another way to grow dahlias is by taking rooted cuttings.
– In late winter or early spring, select healthy dahlia plants and take cuttings from the new shoots.
– Place the cuttings in a rooting hormone and then plant them in a well-draining potting mix.
– Keep the cuttings in a warm and humid environment until they develop roots.
– Once the cuttings have rooted, you can transplant them into the garden after the last frost.
– This method allows you to propagate multiple plants from a single dahlia, making it a cost-effective option.
3. Growing from Seed:
– While less common, dahlias can also be grown from seed.
– Start by sowing the seeds indoors in late winter or early spring, around 8-10 weeks before the last expected frost.
– Use a well-draining seed-starting mix and lightly cover the seeds with a thin layer of soil.
– Keep the soil consistently moist and provide sufficient light for germination.
– Once the seedlings have developed a few sets of leaves and all risk of frost has passed, they can be transplanted into the garden.
– Growing from seed may take longer to produce flowers compared to other methods, but it offers a wider range of variety options.
While tubers are the most popular method for growing dahlias, they are not the only option. Rooted cuttings and seeds also provide viable ways to propagate dahlias. Each method has its advantages and can be chosen based on personal preference, availability, and desired variety. Experimenting with different methods can be a fun and rewarding experience for gardeners.
