Dealing with Honey Bee Swarms


 

Honey bees are valuable and provide tremendous benefits, specifically pollination, honey and wax. However there are times and places where honey bees create an annoyance and a nuisance, and for sting-sensitive individuals, a health threat. One such incidence is when honey bees swarm.

 

Fire Blight of Apple and Pear


Fire blight is a common springtime disease of apple, pear, and related species, including crabapple, hawthorn, cotoneaster, and quince. Leaves on affected branches wilt and turn black, appearing as if scorched by fire. The most characteristic symptom is the curling of affected shoots into curved "shepherd's crooks". Cankers (areas of sunken or discolored bark) may develop on limbs, and the blighted shoots may produce sticky ooze in wet weather.

I've been impressed with the buckeyes blooming on campus this spring. These trees seem to have been unaffected by our late spring frosts or recent downpours.
