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
![Page 6: Sources for Tree Information](https://reader036.fdocuments.us/reader036/viewer/2022062222/568163dd550346895dd536ba/html5/thumbnails/6.jpg)
• 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

Planted to Deep – Root Flare is Buried

Planting Bareroot Trees

![Page 14: Sources for Tree Information](https://reader036.fdocuments.us/reader036/viewer/2022062222/568163dd550346895dd536ba/html5/thumbnails/14.jpg)
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
![Page 15: Sources for Tree Information](https://reader036.fdocuments.us/reader036/viewer/2022062222/568163dd550346895dd536ba/html5/thumbnails/15.jpg)
• 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

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
![Page 22: Sources for Tree Information](https://reader036.fdocuments.us/reader036/viewer/2022062222/568163dd550346895dd536ba/html5/thumbnails/22.jpg)
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 and happy life – well beyond our lifetime

If Your Tree is Planted Right and Pruned Properly the Tree Will Live for Generations
