One of the tools we have for climate resilience and mitigating the effects of urban heat islands in cities is planting more large-scale trees. This new two-sided publication from Dane County Extension Horticulture and the Tree Canopy Collaborative illustrates the steps in planting a tree, whether it is in a pot, bare root or has […]
You may have received or purchased some flower bulbs over the holidays. For forcing, you need to know whether you have a precooled or non-pre-cooled bulb.

Before the ground freezes too far down, it is a good time to put protective fencing around trees and shrubs that may experience damage from deer, rabbit, vole, or mouse feeding over winter.

Several factors cause winter burn on evergreens, including winter thaws while the ground is frozen, dry soil in autumn, a long period of very cold temperatures, […]
