Salvaging Methods

Most native plants can be salvaged. However, successful salvaging requires some knowledge about salvaging techniques and the plants you are trying to rescue. Salvaging will be most successful if done on wet, cloudy days, during the late fall through winter when plants are dormant.

You will need the following equipment: a shovel or flat-bladed spade; a metal file (for sharpening the spade); pruning shears (for pruning branches or roots); and wet burlap bags, lined with wet leaves or mulch (for transporting the plants). Before each salvaging session you should sharpen your spade (wear gloves), so that roots are cut cleanly and easily.

Finding appropriate plants: Focusing on species that are easily-salvaged, look for a plant that is growing by itself; trees and shrubs growing in clumps connected by underground runners are unlikely to survive transplanting.
 
With few exceptions, trees and shrubs are most likely to survive if they are under three feet tall.

Preparing the plant: Check to makes sure the plant looks healthy. If it does, clear the area around it of leaves and twigs (wear gloves). If some of its branches are too long for transporting, they can be pruned back.

Digging the plant: At least eight inches out from the plant's main stem (one foot if the plant is over three feet tall), plunge the spade straight down into the ground as deep as possible. Continue doing this until you've circled all the way around the plant. Now gently work the spade under the plant's roots. If you encounter a root that the spade will not cut in two strokes, cut it with clippers to prevent damaging the root. Cut the root as long as possible

Moving smaller plants: Plants under two feet tall can simply be lifted out of the hole (supporting the roots and attached dirt with your hand), placed in a wet burlap bag, and the roots covered with wet leaves or mulch.

Keep the soil with the plant. Plants that are salvaged with the root ball and soil intact stand an increased chance of survival. The soil also provides important micro-organisms that will innoculate the site where you locate your salvaged plants.

Moving larger trees and shrubs: Root balls (roots plus the surrounding dirt) should be wrapped with burlap and tied into the root ball. This will protect the roots from drying out and ensure that you take with you microorganisms the plant needs to flourish. Two people are usually needed for this procedure, especially for trees and shrubs over three feet tall.

Place a piece of burlap about two or three feet square alongside the plant. Once the root mass has been cut loose, place the spade under the plant. While one person holds the spade handle, the other person (who is wearing gloves) should grasp the main stem of the plant and, using the blade to support the root ball, lift the blade and the plant out of the hole. BE SURE TO LIFT WITH YOUR LEGS, NOT WITH YOUR BACK! Transfer the root ball onto the burlap. Pull the corners and edges of the burlap up to enclose the root ball, and wrap twine around the root ball and burlap to keep it together. If you happen to lose most of the dirt around the roots,  moisten the burlap, and pack wet leaves around the roots. Roots will dry out and die in seconds if exposed to the air, so make sure they stay wet! Roots can be kept moist with a spray bottle, if necessary.

Storing plants: If you need to store plants before you plant them, you might want to build a "capillary bed." This is a wooden frame about one foot deep and usually four feet wide by 8-10 feet long. (You can make it smaller, as long as it is still about one foot deep.) Place the frame on level ground and line it with heavy plastic ( >3 mil). Half-fill it with soil or mulch, and then saturate the soil or mulch with water. Punch holes through the plastic in the corners, halfway up the sides of the bed (level with the layer of soil or mulch), to prevent the entire bed from filling with water.

If possible, pot the plants before placing them in the bed, as this will lessen the number of times the roots have to be disturbed. Then place the plants in the bed on the saturated layer, surround and cover the pots with soil or mulch, and spray the mulch with water. Capillary action will provide the plants with sufficient water so long as there is water in the bed's reservoir. Watch the water level, especially during the summer and dry periods, to make sure plant roots are staying moist, but not so wet that they are constantly saturated and suffocating. Plants stored in a capillary bed can survive for up to a year or more with very little maintenance.
