Now, as we proceed farther into fall, I wanted to give some reminders regarding fall tree and lawn care. Proper care of trees now, in the fall, usually reduces winter damage to trees.

Once the trees’ leaves turn color
and fall off, the tree is dormant so, it is recommended to water trees once
each week until the soil freezes. This
watering after the tree is dormant provides a water reserve for when the tree
comes out of dormancy and it will make a big impact in next year’s overall tree
health. Remember to water not at the tree trunk, but out at the dripline of the
tree to water those feeder roots.
If you have newly planted trees,
it’s important to protect them from winter desiccation. It’s advised to construct sun barriers for
newly planted evergreens on the windward and south side of trees or shrubs to
protect them from winds that will dry them out and protect them from intensive
reflective winter sun. These young trees
can be protected by wrapping burlap between fence posts or propping a wooden
pallet on end. Deciduous trees (that’s
the ones whose leaves turn color) with smooth and dark bark should have trunks
wrapped with a tree wrap to reflect the sun, which will reduce sunscald on the
bark.
Regarding lawns, fall is the time to make another fertilizer application or two. In Montana, it’s recommended to fertilize around Memorial Day, Labor Day, and Columbus Day. The final fall fertilizer application should occur after the last mowing of the year, but about four weeks before the soil freezes. The fall fertilizer applications are key fertilizing times, as your lawn will green up much faster in the spring if it receives this October fertilizer application.
