Bare-root aquatic or emergent species like Lilies, Pickerel Weed, and Common Arrowhead are
supplied in the early spring in bare-root format with little to no foliage. When planting bare-root
plants, submerge the entire root to the appropriate depth and anchor it below the soil surface.
A technique to use with bare-root tubers is to put them in a small, weighted, biodegradable
mesh sack and submerge them at an appropriate depth. The sack will keep the tuber from
floating to the surface, and by the time the plants have rooted into the soil, the sack will have
biodegraded. Other techniques can be used to anchor plants, such as using small piles of loose
gravel,” or planters.Contact Cardno

Plantings may need to be protected after installation. Use
physical barriers such as chicken wire, netting, or twine obstacles to keep out geese,
muskrats, deer, and other animals. Various repellants can also be applied directly to the
plants, but they often need to be re-applied periodically.Monitor and maintain site
To help ensure success, projects need a maintenance and management plan that is flexible
and supports site development goals. While native plants tend to germinate and develop
at a slower rate than ornamental perennials or turf grass, regular maintenance during
the establishment period greatly improves project success. Regular maintenance and
monitoring controls invasive species, ensures optimal moisture levels are present, and
identifies other necessary management actions.
The maintenance of a native landscape can include many different actions:
Tips for bare-root tree and shrub
After delivery, remove plants immediately
from box and store upright to prevent
Keep roots moist until plants are installed.
They may be held in buckets or containers
of water on site; however, if plant material
will not be installed for a week or longer, do
not keep in standing water.
Keep plants in a cold, dark place to prevent
them from breaking dormancy until ready
to plant. Bare-root trees and shrubs can be
stored this way for several days, but check
frequently for signs of mold and to make
sure they are adequately watered.

Selection of maintenance methods partly depends upon timing, but other factors such
as aesthetic goals, project size, and budget also help determine what techniques will
work best. For example, for small areas or sites where chemical applications cannot be
performed, target species may be removed by hand.
