We have to realize that bees are a lot like plants. Not only do they rely on then for their existent, but are effected by their environment. Bees and plants are both influenced by the weather getting warmer in the spring. A crop needs can be calculated in to a cretin numbers of hours of sunlight and heat units to mature. Bees also require the sunny warm days to take advantage of the bloom that is available. Around here the golf courses are just opening for the season, last year they were open 3 weeks ago. The plants are behind, the bees are behind, but both are progressing along together in unison. As a beekeeper we need to adjust our calendar to come in synch with that of natures and the bees. Every year can produce different challenges from the year before so we need to adapt our practices to adapt to the changing conditions.
