Regular pruning throughout the life of the tree promotes healthy growth, maintains the shape of the canopy, and reduces stress on the tree. Dead, diseased and damaged branches should normally be removed right away. One exception is Oak, which is susceptible to Oak Wilt disease, and best pruned while dormant.
Early spring is an ideal time to identify branches and limbs requiring removal. Some trees such as Maple may bleed sap, but this will self-seal and is not harmful.
“Proper Tree Pruning” published by the WI Department of Natural Resources illustrates some key pruning basics.
This All-America Selections winner in the annuals category hasn't got the most alluring name but the Zinnia Profusion Red Yellow Bicolor is an outstanding zinnia new for this year, 2021. The outstanding feature that wowed the judges was that as the growing season progresses the colors will morph from the red/yellow to apricot, salmon, and dusty rose.
Pollinator friendly, this variety can be grown in containers, hanging baskets or beds. Use them for groundcover, low edging or as a medium-height divider. Expect compact mounds of 8 to 14 inches in height. Plant in multiple clusters to get the full impact of the range of striking colors you can expect from this winner. Bloom size is about two and a half inches.
Plant in full to partial sun. No deadheading or staking are necessary. Typical of zinnia, this variety is heat, wind and rain tolerant. If starting your own seeds, first flower will come at 60 days. Transplanted from seedlings, flowering will be at about 30 days.

Bypassing Plant Pathogens: Promoting Tree and Shrub Health Through Proper Pruning
Posted on February 3, 2021
Pruning in the winter can reduce the risk of disease-causing organisms infecting trees and shrubs through pruning cuts.
By Brian Hudelson, Plant Disease Diagnostic Clinic
Although it doesn’t seem like the optimal time to be gardening, February is actually a great time to be out pruning your trees and shrubs to make them more structurally sound and aesthetically pleasing.
Why prune now? Whenever you prune, you create wounds that potentially can serve as entry points for disease-causing fungi and bacteria. If you prune in the spring and summer (when it’s warmer and often wetter), these organisms are very active and more likely land on fresh pruning cuts and infect. When the weather is colder and drier (as it tends to be in February in Wisconsin), disease-causing organisms are much less active and the chances of them infecting though pruning cuts is much reduced.
How do I go about pruning? Check out University of Wisconsin Garden Facts XHT1013 (Pruning Evergreens), XHT1014 (Pruning Deciduous Trees) and XHT1015 (Pruning Deciduous Shrubs) for pointers on how to prune.
Prune only when it’s dry, and decontaminate pruning tools between cuts (or at a minimum between each tree or shrub) by treating them with 70% alcohol (e.g., rubbing alcohol right out of the bottle, spray disinfectants containing ~70% alcohol) or (in a pinch) 10% bleach. Decontaminating tools kills off disease-causing organisms that you might pick up as you prune. Once done pruning, if you’ve used bleach, be sure to thoroughly rinse your tools, and oil them to prevent them from rusting.
By pruning regularly and taking a few simple precautions as you do, you will end up with trees that are beautiful, structurally sound and healthy.
