Planting Balled and Burlapped, Bareroot
and Container Trees
Planting Balled and Burlapped Trees
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
This is unacceptable planting

Planting Bareroot Trees
Tips for Planting
• Bareroot stock maintains ~90% of the root
• They are light to move and/or carry
• They need a smaller hole than the B and B
• 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
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
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

Proper Pruning
• Leads to an overall healthier tree
• A tree that will withstand storms better
• Gives the tree the opportunity to have a long
