Dahlias are breathtakingly gorgeous late-season flowers that bloom from midsummer through fall in a rainbow of color. Dahlias are perennials in Zones 8 and higher; in cold climates, they need to be dug up and stored until spring. Learn how to plant dahlia tubers and great tips on how to grow dahl

I live near Portland, OR. Do I need to lift my dalias?
Check your hardiness zone. If you are in 7 or above, you should be alright leaving them in the ground.
Six years ago, I bought a package of seed dahlias and planted them in an area in front of our house which is somewhat protected from the weather. The first year they bloomed and were about six inches high. Since then, they have spread over the area and bloomed on their own producing beautiful variety of colors. I have never dug them up after blooming but left them alone. The plants are 12 inches to 3 feet high. I didn't think dahlias spreads. What type of dahlias are these?
We’ve only grown dahlias from tubers, is is tradition. However, it is true that that the dahlia flower will produce both seeds and tubers when grown so you could propagate from either. It doesn’t matter which type of dahlia because the tubers will always and consistently produce copies of their “mother” dahlia, but the seeds will not. According to the American Dahlia Society, dahlia seeds will produce varieties different from the parent plants, so propagation from seeds is used primarily to develop new cultivars. Think of it as the dahlia “mother” reproducing with any plant “father” whose pollen an insect carried to the mother. Therefore, it’s not surprising you had a diverse variety of children, since they had the same mothers but different dads. The seeds you plant will never grow true to type but that’s part of the adventure.
I’m in California—how many years can dahlias stay in the ground before you need to divide? Three years?
Lucky you. In your moderate climate, it’s easy to just let Dahlia tubers stay in the ground year-round. However, dividing your dahlias will result in more flowers. It’s best to go by signs that a plant may need dividing:
• A doughnut-type hole in the center of a plant forms as older portions die
• Lots of foliage but not many flowers
• Stunted growth
• Yellowish leaves

Have you ever had success planting them early in pots for an early forced bloom? I have a wedding in early June.
I have! I live in Minnesota and started them in pots in our heated garage in March-April. I didn't know if it would work because they looked like prunes, but almost all of them sprouted. It was very satisfying :)
I planted them outside in the ground in early June.
Good Luck :)
Anyone, anyone? We here at the Almanac have not tried planting/forcing dahlias early. However, the American Dahlia Society has! See the web site, https://www.dahlia.org/growing/fundamentals-of-growing-dahlias/#:~:text=If%20you%20want%20blooms%20as,most%20parts%20of%20the%20country, with this specific observation: If you want blooms as early as possible, you can start the tubers indoors (fig 4) in good light about a month before planting time. You will then have a small plant ready at planting time. Dahlias can be planted as late as mid-June in most parts of the country.
