Minnesota has many native trees that can be used for landscaping. While commercial production is limited for many native species, each year nurseries produce more of these plants for sale. However, many others are available only in the wild and must be moved from their native habitats if they are to be planted in the landscape.

Legally, plants can only be transplanted from the wild when dug from private land or with permission. Even though they are native to this area, these trees require careful site selection. You must duplicate their natural growing environments as closely as possible if they are to thrive in the home landscape.

Plants are usually dug from the wild without soil on their roots. They should be transplanted in early spring before growth starts. This means they need to be identified in a dormant condition. If you can identify the plants only when they have leaves or flowers, mark them during the growing season, then move them the following spring.

It is usually better to move small plants, because even with careful digging, only a small percentage of their roots will remain. Trees that develop a tap root, such as oaks and nut trees, are particularly difficult to transplant and should only be moved as very young plants.

Nursery-grown plants typically have better root systems than those dug from the wild. This accounts for the higher percentage of nursery-grown plants that survive transplanting and become reestablished more quickly. Root pruning a year or two before transplanting from the wild will help develop a more compact root system. To root prune, push a sharp shovel straight into the ground, forming a circle around the tree that extends one foot from its trunk.

Pay attention to spacing and symmetry as you prune; be sure to maintain the tree's natural form. Prune any broken, diseased, or dead branches and branches that grow back towards the center of the tree. Eliminate branches that come out at a very narrow angle from the trunk. Thinning twigs on the trunk and larger branches also helps, because there will be fewer leaves to lose moisture in hot, windy weather. But you must be careful not to overdo it. Those leaves produce energy for the tree that will help it become established in its new location.

Planting seed is another method of obtaining hard-to-find native plants. However, woody plants are more difficult to start from seed than most herbaceous plants. Some seeds may be viable for only a short time; some might require two or more years to germinate. Oak and nut tree seeds will not germinate if they are dried prior to planting.

Most woody plant seeds require stratification in moist sand at 32 to 40 degrees F for three or four months prior to planting. Planting stratified seed directly outdoors in spring is generally more satisfactory than attempting to start them indoors.

You can also plant tree seeds outdoors in fall so they are stratified "naturally" over the winter. You must protect the seed bed from rodents by covering the area with mesh hardware cloth. Remember to remove it in spring before seedlings emerge.

Transplant the seedlings in spring after one or two year's growth. Choose their permanent site carefully. Soil texture, drainage, and pH should be similar to conditions they experience growing wild. Moisture, temperature and light levels must also be considered.

Water young trees weekly (unless there's ample rainfall) the first few years after transplanting. Control pests and weeds to reduce competition during this time, also. Spread three to four inches of woodchip mulch over the root area to help reduce weed growth and conserve moisture.

To prevent sunscald, wrap tree trunks each autumn until they develop corky bark, but be sure to remove the tree wrap early each May. Provide rodent protection by encircling young tree trunks with a cylinder of quarter-inch mesh hardware cloth.

The following trees are native to this area or have been planted at the Minnesota Landscape Arboretum. Their mature size is influenced by many factors including light, water, soil, fertility, competition and length of growing season. They are often taller under forest conditions than when grown in an open area. Sizes listed here are probably maximums under Minnesota forest conditions.
