Seasonal care for trees & shrubs: Health

Keep a watchful eye for problems that may be developing on the plants in your landscape. Timely prevention is always more effective and economical than reacting to problems once they have developed. Certain samples can be sent to your local Plant Disease Clinic (.pdf) for diagnosis.

Seasonal care of trees & shrubs: Stem and branch protection

The stems of landscape trees and shrubs may need protection from animals or mechanical equipment, especially during the winter months. Animal damage (feeding or rubbing) can be avoided by placing wire mesh or hardware cloth at least 3” from the stem. Mechanical damage (e.g. lawn mower or weed whip abrasion) can be avoided when a mulch ring (see mulch) or a plastic guard is in place. The plastic guard should only encase the portion of the lower stem that is most likely to be damaged by lawn equipment. As the tree grows the plastic guard will need to be removed and replaced in order to prevent girdling or stem constriction.

Seasonal care of trees & shrubs: Fertilizing

The recommendations in this chart refer only to nitrogen applications. Before fertilizing your landscape with a complete fertilizer (nitrogen-phosphorus-potassium), contact a soil testing laboratory for a basic soil test [For MN only: U of MN Soil Testing Labratory]. A basic soil test will provide you with readings on organic matter, pH, cation exchange capacity, macronutrients and micronutrients (Smiley, 2003). Soil testing laboratories may offer timing and quantity recommendations for complete fertilizers (N-P-K).

Seasonal care for trees & shrubs: Staking or guying

Staking and guying of trees is rarely needed and is only necessary when the tree will not stand up on its own. These practices may be necessary for 1-3 years while roots are growing and beginning to stabilize the tree. Check attachment points on the stem every 3 to 6 months, loosen if necessary and remove within one year of placement.

Seasonal care of trees & shrubs: Pruning deciduous branches

How to prune trees is an excellent publication designed to illustrate the types of pruning that can be done, how pruning cuts are made, when to prune different plants, and more.

Waiting until the plant is dormant is the safest time to do any live-branch pruning. However, unless the tree or shrub is susceptible to infectious disease (e.g., oak wilt, fire blight), removal of weak, diseased, crossing, rubbing, or dead limbs can be done throughout the year if needed.

Seasonal care of trees & shrubs: Shearing evergreen shrubs

Evergreen shrub shearing is a practice that can be used to maintain a geometric and formal shape of the plant. It is important to note, however, that once a shape has been formed yearly maintenance is required to preserve the design.
