Spring mason bees need a minimum daytime temperature of about 55F/13C (don’t worry about nighttime temperatures) and they need open blooms to feed.
Chewing out of cocoons takes time. You should allow for this time in your planning for cocoon release. Fluctuations in weather can slow the bees’ emergence from their cocoons and it can take up to two weeks (or longer) for the bees to emerge.
