Direct sow or start indoors? Learn the pros and cons of each zinnia seeding method to maximize your blooms and enjoy a vibrant garden.
The biggest question you’ll need to solve for yourself is HOW you want to start your zinnia seeds because there are two ways to get your zinnia journey rolling: starting seeds indoors or sowing them directly outdoors. So consider these factors carefully.
Cooler climatesStarting zinnia seeds indoors allows you to get a head start on the season and enjoy earlier blooms before the last frost. This is especially beneficial in areas with short growing seasons.
Warmer climatesDirect sowing zinnia seeds is perfectly feasible as long as the threat of frost has passed. It’s simpler and requires less equipment, making it ideal for warmer regions.
ConvenienceDirect sowing zinnia seeds outdoors is generally quicker and less work compared to starting seeds indoors, which requires containers, grow lights (potentially), and more attention to watering and temperature.
ControlStarting zinnia seeds indoors gives you more control over germination conditions and seedling care, potentially leading to stronger plants. It also allows you to choose specific varieties that might not be readily available as seedlings.
Planting timeIf you want blooms earlier in the season, starting indoors is necessary. For later summer blooms, direct sowing might suffice.
CostIf you are on a budget, starting seeds outdoors may be more cost-effective than purchasing expensive grow lights and other equipment needed to be successful.
VarietySome zinnia varieties might germinate better indoors, especially those with smaller seeds. Check the specific needs of your chosen variety.
