#1. Protect flowers with fungicides during bloom. See this article on disease control considerations at bloom.
#2. Consider honeybee health and safety for any disease control measures taken during bloom. Protect your investment. Spray only fungicides at bloom. Leave insecticides, nutrients, and adjuvants out of the tank at bloom. Provide clean water for bees, and set hives in a spot where the morning sun will warm them and encourage early morning bee activity.
#3. Hang San Jose Scale pheromone traps during the last week of February. Remove or mow weeds and cover crops before bloom to aid in frost protection.
