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.

Post-planting protection:

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

mold growth.


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.

Tips for bare-root aquatic and

emergent species installation


Because they do not remain viable for long

after harvesting, schedule shipment to

arrive as close to planting date as possible.


Take plants out of the packaging, place

upright in a container, and keep in fresh

water until planting (similar to fresh-cut



Plant roots must remain submerged at all

times until just before planting, even when

staging at the planting site.


Change water every few days if unable to

plant immediately.

Creating a Native Landscape


Regular site inspection and monitoring




Selective herbicide application


Overseeding and supplemental planting


Water control and temporary irrigation


Prescribed burning

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.
