This year I am intentionally changing how I start my annual flowers, and what I’m growing.

In the past, I’ve had a tendency to sow too early and start too many varieties. While some plants did beautifully, those requiring a long indoor growing period before planting out often struggled. I wasn’t consistently matching heat and light to their specific needs. Part of this was because I just don’t have the capacity to do so. While I can heat my greenhouse, I cannot maintain ideal germination temperatures early in the season (when it’s consistently -20°C at night). I can move trays to the floor for mor heat but then they lose light; if they sit higher for light, they do not have enough warmth.

This year, I am committing to a more deliberate system:

• Starting seeds based on the longest recommended indoor timing, not when I feel eager.
• Using heat mats or my heated greenhouse floor more strategically for proper germination temperatures. I’ve invested in an automated controller that should allow me to create multiple heat zones for different plants.
• Moving seedlings promptly to strong light once sprouted. I purchased two new grow lights that allow adjustable light intensity and a wider span of light, so I can better match light levels to each growth stage. I’ll combine that with the controller to automate the duration of light as well.
• Matching sowing method (germination tray vs. direct cell pack) to the plant’s growth habit. I had success with this approach last year and plan to be more disciplined with it.

To keep this experiment manageable, I’ve also reduced my annual selection significantly.

My commitment to myself this year:

• Fewer varieties
• Stronger seedlings
• Proper timing
• Better light management
• Intentional transitions from germination to growth

My goal isn’t to grow more, it’s to grow better.
