Seasons by Dahlia: A Guide to the Year-Round Beauty of Dahlias

Dahlias are one of the most popular flowers in the world, and for good reason. They come in a wide variety of colors, shapes, and sizes, and they bloom for a long period of time. With proper care, dahlias can thrive in all four seasons.

Spring: Planting and Early Growth

Spring is the time to plant dahlia tubers. Dahlias are tender bulbs that should not be planted until the soil has warmed up. In most areas, this is around the last frost date.

When planting dahlias, choose a sunny spot with well-drained soil. Dig a hole that is twice the width of the tuber and just deep enough so that the top of the tuber is level with the soil surface. Water the tuber well after planting.

Dahlias will begin to sprout within a few weeks of planting. Once the sprouts are a few inches tall, you can begin to fertilize them. A balanced fertilizer, such as a 10-10-10 fertilizer, is a good choice for dahlias.

Summer: Blooming and Maintenance

Dahlias typically begin to bloom in mid to late summer. They will continue to bloom until the first frost. To encourage blooming, deadhead spent flowers regularly.

Dahlias need regular watering, especially during hot, dry weather. Water the plants deeply at the base of the plant, avoiding the foliage.

Dahlias are also heavy feeders. Fertilize the plants every few weeks with a balanced fertilizer.

Fall: Preparing for Winter

In fall, as the days get shorter and the temperatures cool, dahlias will begin to go dormant. At this time, you can dig up the tubers and store them for the winter.

To dig up dahlia tubers, carefully dig around the plant with a shovel. Be careful not to damage the tubers. Once the tubers are dug up, brush off any excess soil and allow them to dry in a cool, dark place for a few weeks.

Once the tubers are dry, store them in a cool, dark place. The ideal storage temperature for dahlia tubers is between 40 and 50 degrees Fahrenheit.

Winter: Dormancy

Dahlias are dormant during the winter months. During this time, the tubers will need very little care. Just check on them occasionally to make sure they are not rotting or drying out.

Common Mistakes to Avoid

Here are some common mistakes to avoid when growing dahlias:

• Planting tubers too early. Dahlias are tender bulbs that should not be planted until the soil has warmed up. Planting tubers too early can lead to rot.
• Not watering the plants enough. Dahlias need regular watering, especially during hot, dry weather. Watering the plants too little can lead to stunted growth and poor flowering.
• Fertilizing the plants too much. Dahlias are heavy feeders, but they can be easily over-fertilized. Over-fertilizing can lead to burned roots and poor flowering.
• Not deadheading spent flowers. Deadheading spent flowers encourages the plant to produce more blooms. Leaving spent flowers on the plant can lead to a decrease in flowering.
• Digging up tubers too early. Dahlias need a period of dormancy in order to produce new growth the following year. Digging up tubers too early can lead to weak growth and poor flowering.

Conclusion

Dahlias are a beautiful and easy-to-grow flower that can add color and beauty to your garden all year long. With proper care, dahlias can thrive in all four seasons.
