Growing dahlias is rewarding and easier than you might think. At Peak Bloom, we love seeing new gardeners bring these beautiful blooms to life! Here’s our guide to planting and caring for dahlias, complete with the top tips for soil, watering, and general maintenance that’ll help your garden shine.
1. Find the Perfect Location for Dahlias
Dahlias thrive in full sun, so choose a spot where they’ll receive at least 6 hours of direct light daily. They prefer well-drained soil, so if your garden has heavy clay, consider adding compost or coarse sand. This helps create the loose, well-draining environment that keeps their roots happy and healthy.
2. Timing is Everything: When to Plant Dahlias
Wait until all risk of frost is gone and the soil warms to about 60°F. In many areas, this means planting in late spring or early summer. Dahlias planted in warm soil are more likely to thrive, so don’t rush!
3. Proper Planting for Strong Dahlia Growth
When you’re ready to plant, dig a hole 4-6 inches deep for each tuber and place it horizontally, with the “eye” (growth point) facing up. Cover with 2 inches of soil, adding more as the plant grows. Give each plant 18-24 inches of space to promote airflow and prevent disease, helping them bloom fully.
4. Add Support and the Right Fertilizer
Since many dahlia varieties grow tall, consider adding stakes or supports at planting time to keep them upright. Use a low-nitrogen fertilizer to encourage bloom production. High-nitrogen fertilizers can lead to excess foliage, reducing the number of flowers your plants produce.
5. Keep Your Dahlias Hydrated Without Overdoing It
Dahlias appreciate regular moisture, but go easy on the watering until they’ve sprouted. Once established, water deeply once or twice a week to keep the soil moist but not soggy.
