November Tips and Tasks

  • Prune dormant shade trees that need to be pruned. Begin by removing all dead, diseased branches, and making any necessary cosmetic cuts. Do not cut branches flush with the trunk. Leave the branch collar (swollen area on the trunk of a tree or a larger branch) but do not leave a stub.

  • Topping (photo above) is the not the correct pruning technique to help control the size of a tree. Crown reduction, pruning entire branches at their point of origin, is recommended if a tree must be reduced in size.

  • Be on the lookout for spotted lanternfly adults and egg masses. Report any finds to the Maryland Department of Agriculture.
  • Mulch your perennials after the first hard freeze. This helps to protect them from frost heaving caused by the freezing and thawing of soil.  Mulch helps moderate temperature fluctuations, reducing this problem. 

November Tips and Tasks

  • Mulch your perennials after the first hard freeze. This helps to protect them from frost heaving caused by the freezing and thawing of the soil. Mulch helps moderate temperature fluctuations, reducing this problem. Mulch should be no more than 2-3″ deep.
  • Be on the lookout for Spotted Lanternfly adults and egg masses. Report any finds to the Maryland Department of Agriculture.
  • Save the time and effort of raking, blowing, and picking up leaves. Leaves are a valuable source of organic matter to improve the soil in a lawn and garden. Leaves that fall onto the lawn can be shredded with a lawnmower and left to decompose naturally in place. Fallen leaves also make an excellent mulch for garden beds. Shred them first by running over them with a mulching mower or a leaf shredder.

  • Typically, November is too late to broadcast lawn seed and expect it to survive the winter. Consider waiting until early spring.
  • This is still a good time to control wild garlic, clover, ground ivy, chickweed, and other difficult weeds with an herbicide if daytime temperatures remain in the sixties. Do not spray herbicides around ponds or on breezy days. Always read and closely follow all label instructions.
  • According to Maryland’s Lawn Fertilizer Law (PDF), the last application of fall fertilizer needs to be applied before November 15th.
