DAHLA SEED STARTING BASICS

1) Start seeds indoors 4-6 weeks prior to planting. The paper towel germination method is recommended (see full guide, linked below).

  • Do not direct sow
  • Do not germinate on unregulated heat mats
  • Germination at room temperature (~70 °F) without a heat mat is recommended.


2) Harden seedlings off after last frost.

3) Plant seedlings with 4-5 leaf sets in the field. Follow date recommendations for your growing zone; a general rule of thumb is when you would plant out tomatoes - after your last frost and when soil temps are above 55°F.

While growing from seed is an adventure and results cannot be predicted or guaranteed, the intentional curation of available genetics equals an increases possibilities for higher petal counts and similar forms among seedlings. Seed parents are predominantly ball and formal decorative forms and are open pollinated amongst other fully double dahlias. A perfect jump-start for the aspiring cut flower dahlia hybridizer.

Dahlia seedlings bloom and make tubers in one growing season. You are experiencing a treasure to be explored in your garden when you grow dahlias from seed. Dahlia seeds DO NOT grow true to the parent variety and there are endless possibilities when growing dahlias from seed. Each seed is a surprise!

Seeds from our Hybridizer Mix may exhibit a larger window of potential days to germination than other mixes. This is part and parcel with growing dahlias from a mix of fully double seed and pollen parents. We've had seeds germinate anywhere from a few days to day 20, so implement best practices and stay the course. Please note that while we select only the finest seeds for sale in each mix, dahlia germination rates are variable and germination rates for our mixes have not been determined in the lab. Following best practices will aid your success when growing dahlias from seed. See the section below entitled 'Growing From Seed' for more information (website only).
