Dahlia flowers are incredibly popular among gardeners and come in a lovely mixture of colors. They bloom from summer until the first frost of fall.
All Dahlias can very easily be grown as half-hardy annuals and flower the first year when grown from flower seeds.
The delightful blooms will attract bees and butterflies to your garden.

✅ Sow Dahlia seeds indoors 4 - 6 weeks before the average last frost. Lightly cover the flower seeds with soil or peat moss only the thickness of the seed itself.
✅ As soon as seedlings emerge, provide plenty of light on a sunny windowsill or grow seedlings 3-4 inches beneath fluorescent plant lights turned on 16 hours per day, off for 8 hours at night. Raise the lights as the plants grow taller. Incandescent bulbs will not work for this process because they will get too hot. Most plants require a dark period to grow, do not leave lights on for 24 hours.
✅ Before planting in the garden, seedling plants need to be “hardened off”. Accustom young plants to outdoor conditions by moving them to a sheltered place outside for a week. Be sure to protect them from wind and hot sun at first.
