Read the mechanism and conditions

Less frequent mowing can allow more flowers to develop and provide resources for insects. Field studies show that flower abundance and bee responses do not always peak at the same mowing interval.

No three-week schedule works everywhere. Adapt to local plants, fire risk, access and seasonal growth. This is habitat management, not a count of bees saved.
