Winter can be challenging for trees due to the harsh weather conditions, but it’s also an ideal time for certain tree maintenance activities. 

Richard Smith, a Certified Arborist at Bay Area Tree Specialists, offers his expertise on how to care for your trees during the winter months, particularly focusing on the period from November through February.

The Ideal Pruning Season for Evergreens

With its colder temperatures, winter is the perfect time for pruning Pine, Cedar, and most Evergreen trees. The rationale behind this timing primarily relates to the sap flow in trees.

Understanding Sap Flow and Tree Health

During the hotter months, pruning an evergreen tree leads to excessive sap loss from the wounds, which can cause several issues:

  • Sap Dripping: The sap can drip onto patios, driveways, and roofs, creating a sticky mess that’s difficult to clean.
  • Pest Attraction: Pests, particularly beetles like the Turpentine Beetle, are attracted to the sap’s scent and can infest the tree, often leading to irreversible damage and even tree death. This is a significant cause of mortality in Monterey Pine (Pinus radiata).

In the colder months, the sap flow slows down or becomes dormant, remaining primarily in the root system until the weather warms. 

Pruning during this inactive season results in minimal sap loss, reducing the risks associated with sap attraction.

Risks of Incorrect Pruning

Pruning seems pretty straightforward, right? Just snip away the extra branches, and you’re all set. But wait a minute! It’s not quite that simple.

Pruning your trees the wrong way can lead to many problems, some of which can last for the tree’s lifetime. Let’s break down what can go wrong:

  • Unwanted Growth: Imagine giving yourself a bad haircut; it’s the same with trees. Poor pruning can lead to awkward growth patterns and weak new branches. It’s all about making the right cuts in the right places.
  • Open to Illness: Just like a bad cut on your finger can get infected, the same goes for trees. Incorrect pruning leaves them vulnerable to fungi and other diseases, especially if the stakes don’t heal properly.
  • Pest Paradise: Pests love setting up homes in poorly pruned trees. They’re like tiny invaders marching in at the first sign of weakness, causing more damage the longer they stay.
  • Stress, Stress, Stress: Trees feel stress too! Bad pruning practices can weaken your tree’s structure and health, leaving it struggling to survive, especially during those harsh winter months.
  • Safety Hazards: Loose, weak, or dead branches can be a safety risk. They can fall during storms or even on calm days, damaging property or causing injuries.

So, what’s the lesson here? Pruning is a job for the pros — arborists who know what they’re doing. 

They understand that every cut made influences the tree’s future growth and health. It’s not just snipping away branches; it’s shaping the tree’s future!

Oak Tree Maintenance: Fighting Fungus and Mold

Oak trees require a different pruning schedule due to their susceptibility to fungus and mold.

  • Avoiding the Wet Season: Pruning during the wet, rainy season can expose oak trees to fungal infections at the wound sites. The dry months, typically July to September, are the safest for pruning to prevent mold and disease proliferation.
