If you live in a climate where you can overwinter them in the ground, it’s as simple as cutting the stocks down to the soil level. Mulching them will give them added protection through the winter.If you plant one healthy dahlia tuber, you can typically expect to harvest between 20 and 60 flowers in a single season. This number varies based on the variety of dahlia and how you care for the plant.The ideal time to plant dahlias is in spring, once the danger of frost has passed – typically around Labour Day weekend (late October). Dahlias are frost-sensitive, so planting too early can damage young shoots. In frost free-regions dahlias can be planted in spring, from September onwards.Dahlias grow best when they receive a consistent supply of water. Drip irrigation is ideal, as it directs moisture to the root zone while keeping the foliage dry. If you are hand-watering, it’s best to water deeply once or twice per week.
What is the best time to sow dahlia seeds?
Growing Dahlias From Seed Sow dahlia seeds in February to March for flowering mid to late summer. Use a good peat-free compost and sieve the compost both below and over the seed, gently firming the compost with a tamper, label for identification. If tubers are stored properly, there’s no rush—dahlia clumps can remain whole until just before planting. Some growers prefer to wait until spring to divide, ensuring tubers stay intact longer, which helps prevent excessive moisture loss.Dahlias take 90-120 days to bloom from planting It’s true! That’s why I plant my tubers in pots indoors 4-6 weeks before our last frost date. I have early blooms this way.Freezing conditions will always kill them. After one to two weeks they should be ready to store. Traditionally dahlia tubers were dusted with Yellow Sulphur to prevent fungal infection. This is recommended as a plant nutrient and soil acidifier, but many use it as a preventative measure on dahlia tubers.To understand how dahlia plants come back every year, it helps to look at what is happening beneath the soil. Dahlias do not grow from seeds or traditional bulbs; they grow from tubers. A tuber is a thickened, potato-like root that stores energy and nutrients for the plant.

Why are dahlias considered high maintenance?
Overwatering may cause Dahlias to wilt and droop. Too much water, from either overwatering or poor soil drainage, causes tubers to rot, which may lead to yellowing or spotty leaves.

Give each its own pot to prevent nutrient competition.Spider Mites are the biggest and most common predators of dahlias. These pests will cause your plants to look brown around the base with possible spots on the leaves. Spider mites feed on leaves during the summer and return to the soil for the winter and must be sprayed to prevent future issues.While dahlias are resilient, there is a limit to how much you can crowd them before their health suffers. The sweet spot for high-density planting generally falls between 9 and 12 inches apart.

Sunflowers (Helianthus) Not only do they grow tall and potentially shade out your dahlias, but they also have massive root systems that deplete the soil of nitrogen and water.
