Planting Balled and Burlapped, Bareroot and Container Trees http://www.wildbirds.org/oaks/oaks.htm
Planting Balled and Burlapped Trees http://www.extension.umn.edu/distribution/naturalresources/components/DD7415b.html
Tips for Planting B and B Trees All ties, burlap and wire cages should be removed If the tree is too large to remove the entire cage, remove the upper 1/3 to 2/3s of the cage – use tin snips for removal – roots of trees are usually found in the upper 24-36” of the soil Back fill the hole with soil that is unamended
Never put mulch up against the trunk of trees like volcanoes. This causes problems with the bark and encourages adventious roots which weaken the original root structure.
Drawbacks to Planting B and B Trees Balled and Burlapped trees lose 50-80% of their root systems when dug from the nursery If the root flare is buried in the nursery, more roots are lost Takes one year for every each of caliper for the roots to re-establish themselves after they are dug
This is unacceptable planting
Properly Planted Penn Treaty Elm
Planted to Deep – Root Flare is Buried
Planting Bareroot Trees http://www.learn2grow.com/gardeningguides/trees/planting/BareRootTrees.asp
Tips for Planting Bareroot stock maintains ~90% of the root mass They are light to move and/or carry They need a smaller hole than the B and B tree
Backfill with unamended soils and make sure the root flare is level with the nature soil line These trees only need to be staked if they are in areas where there is a great deal of foot traffic and activity All new plantings should receive one inch of water per week during establishment ~10 gallons for a smaller tree
Place the Roots on a Mound and Spread Them Out – Then Backfill http://www.learn2grow.com/gardeningguides/trees/planting/BareRootTrees.asp
Drawback to Bareroot Trees Small window for planting in the spring and fall of the year when plants are dormant Root systems need to be dipped in hydro gel to keep them moist until planting Need to have enough volunteers or staff for planting large quantities
Planting Containerized Trees http://www.wildbirds.org/oaks/oaks.htm
Tips for Planting Make sure to check that there are no circling roots to cause girdling Make sure that the root flare is at ground level Backfill with unamended soil
Drawbacks to Container Trees If the trees have been growing to long in the container – their roots may be to girdled
Girdled Roots and Buried to Deep
Things Not to Do
Healthy Root Flare
Pruning Reasons to Prune Three Ds o Damaged o Diseased o Dead
Understanding Tree Anatomy
Tree pruned outside branch collar
Pruning Cut Should Look Like a Donut When Healing

Proper Pruning Leads to an overall healthier tree A tree that will withstand storms better Gives the tree the opportunity to have a long and happy life – well beyond our lifetime
If Your Tree is Planted Right and Pruned Properly the Tree Will Live for Generations
