"Meteorological spring started on March 1, and astronomical spring began on March 20. However, plants do not follow these calendars and instead leaf out when it is warm enough."
"The first emergence of leaves can be estimated by temperatures since the start of the year, as a certain amount of warmth needs to accumulate before leaves appear."
"This warmth is typically measured through a metric called growing degree days, which quantifies the necessary warmth for plant growth."
Meteorological spring began on March 1, while astronomical spring started on March 20. However, plants determine their own season based on temperature. They do not adhere to any calendar and begin to leaf out when sufficient warmth accumulates. The emergence of leaves can be estimated using a metric known as growing degree days, which quantifies the necessary warmth for plant growth since the beginning of the year.
