Why the 2021 spring was a biological stalemate for your garden
In short: Compare the dramatic growth differences between the mild 2020 season and the harsh 2021 spring. This video explains how specific temperature thresholds and late frosts dictate the pace of plant development.
The video contrasts the 2021 season with the exceptionally warm 2020 period to illustrate how temperature volatility affects growth. While 2020 saw average day temperatures of 18°C in April, 2021 saw only 13.4°C. The primary culprit for the 2021 stagnation was the frequency of frost: April 2021 recorded 16 frosts, far exceeding the average of 5.
The data highlights that while May 2021 temperatures were only slightly below average, the damage from April's cold nights (averaging -0.2°C) created a significant delay in plant establishment. This comparison serves as a case study in how specific environmental thresholds—rather than just general seasonal trends—determine garden success.
