Preparing Seedlings for Planting

Wrapping Seedlings

The wet wrap method is recommended for seedlings. Wrapping is not required if other precautions ensure that root systems are not exposed to drying. However, wet wrap offers some insurance against root drying and may be more efficient than spending extra time inspecting seedlings when planting during sunny weather.

Other methods, such as placing seedlings in insulated tree bags, are acceptable so long as monitoring shows that roots are not drying. Cellulose products can be mixed with the water before the trees are dipped. However, if the slurry is too thick or is rubbed on the roots, the roots will be harmed.

Wrap trees under full shade and in an area protected from wind. When possible, wrap seedlings inside buildings or in canvas shelters.

Remove seedlings from boxes in groups of 20 to 50. Roots may be dipped briefly in tubs of clean fresh water or misted before wrapping.

Wrap trees in wet tree-wrapping fabric or clean burlap, about 15 by 30 inches. Tree-wrapping fabric is lighter, easier to prepare, and can be disposed at the end of the planting season. Wrapping material must be clean to avoid spreading molds from one bundle to the next.

Separate seedlings gently and place one layer on the wrap. Roots should not be tangled. The wrap should extend about 6 inches below the ends of the roots. Fold the bottom 5 inches of wrap over the roots, being careful not to fold the roots. Roll the bundle and fasten it with a nail or plastic tie. The planter must loosen the bundle slightly before planting to prevent the roots from being stripped when seedlings are removed. Indicate the seed lot and other information for bundles, such as time of wrapping and the name of the person doing the wrapping, on colored flagging or other tagging.
