Winter Dessication of Evergreens

The Plant and Insect Diagnostic Clinic has recently received specimens of pine, spruce, fir, yew and other evergreens.

Unusual Exposed Honey Bee Comb

Alert reader and generous photographer Gary Koehler shared the photos below of an exposed honey bee comb built on rocks along a river in Jackson County, Iowa. The colony was spotted late last November and checked again during the gorgeous warm weather of March 1 when the photos were taken.

Transplanting Small Trees

Occasionally the need arises to move trees within the home landscape. Early spring (before growth begins) and fall (after leaf drop) are the best times to transplant deciduous trees. Evergreens are most successfully transplanted in early spring and late summer (late August to mid-September). To minimize damage and improve their chance of survival, dig and move trees with balls of soil adhering to portions of their root systems. The soil should be moist when the plant is dug. If the soil is dry, thoroughly water the area 3 to 4 days before digging.
