Tree Care

  • Newly Planted Tree Care: How you care for your new tree can help it survive and thrive. Read about Caring for Newly Planted Trees from the Minnesota DNR.

  • Pruning: Proper pruning is essential to tree health. Learn proper techniques in the How to Prune guide from the US Forest Service.


  • Fertilizing: Before you fertilize, test the soil to see if nutrients are needed. You may harm or "burn" your tree if you apply fertilizer when it's not needed. Soil testing kits are available at garden centers. Another option is to send a sample to the University of Minnesota – Soil Testing Laboratory, which offers a wide range of tests including fertility, pH, organic matter and soluble salts.
