Bilbao

Bilbao Dahlias are a beautiful and easy-to-grow flower that is perfect for gardeners of all levels. Here is how to get started:
• Bilbao Dahlias are sun lovers and prefer full sun over anything else. So choose the right location where it receives plenty of sunlight and plant it in well-drained soil because they don’t like wet feet.
• Water regularly. How do you know when your Bilbao Dahlias need water? Feel if the soil is dry or moist, then keep the soil evenly moist but not waterlogged.
• Fertilize monthly and use a balanced fertilizer to promote healthy growth and abundant blooms. You can do this after 30 days from the planting day and then every 2-4 weeks.
• Stake and prune, you don’t want your Dahlias falling over. Stake tall stems to prevent them from falling over, and prune regularly to promote bushier growth.

Good news, yes they do! To encourage multiplication, it is recommended that you divide the tubers and replant them every few years. This will help to keep the plant's health, promote better blooms, and increase the overall size of your Dahlia patch.

Your stock of dahlias can expand exponentially by dividing the tubers once the plant season has come to an end. It is a simple process that can be done in just a few steps.

Firstly, dig up the tubers after the first frost and let them dry in a cool, well-ventilated area for a few days. Once dry, cut the tubers into smaller pieces, each with at least one "eye" or growing point. Plant the pieces in well-drained soil, about 6 inches apart, and water thoroughly. Keep the soil moist and in a warm, sunny location until the shoots emerge. Once the shoots reach about 6 inches tall, they can be divided and replanted in individual pots or in the garden.

Yes, they do come back every year. While these Bilbao Dahlia may only last for a season, the tubers themselves are hardy and will return every year, but only if cared for properly.
To ensure that your Bilbao Dahlia tubers come back year after year, you should plant them in well-drained soil and water them regularly.

After the blooms have faded, it is important to cut back the stems and allow the foliage to die back naturally. Once the foliage has turned brown and withered away, the tubers can be lifted and stored in a cool, dry place until it is time to plant them again the following spring.

Do you live in an area with a warmer climate, such as USDA zone 8 or higher? Then you can just leave the tubers in the ground, after you cut back the stems and remove the foliage.

If you do not divide these tubers regularly, they can become overcrowded and lead to poor blooming and stunted growth. Overcrowding can also lead to the buildup of disease and pests in the soil, which can harm the health of the plant.

So if you do not divide Bilbao Dahlia tubers, you risk losing the beauty and vitality of the plant. Regular division every year or two will keep the plant healthy and help it produce beautiful blooms year after year. Make sure to divide your Bilbao Dahlia tubers to keep them healthy and thriving!
