Planting is the act of placing a young tree or shrub that is either barerooted, balled
and burlapped (B&B), or containerized into the ground to grow.  If for any reason the plants cannot be planted immediately, make sure the soil and/or roots are kept moist until the time of planting.

In the Midwest region, tree planting of bareroot trees and shrubs is best done when the plants are dormant in the spring or at the end of the growing season (fall).  Balled and burlapped (B&B), containerized and container grown plants can be planted throughout the growing season, but with caution during the summer months.  During the summer, heat and periods of drought are tough on newly planted trees and shrubs.

Make sure you have the ability to water the trees and shrubs as needed; therefore, do not plant more than you can maintain.

Often the installation of trees and shrubs involves transplanting- the act of digging trees and shrubs from a site (e.g. nursery) and planting them in your landscape. This digging can result in the loss of ~90% of a tree’s root system; thus, some plants need a long growing season following this tranplanting to recover from the root loss. Therefore, the list below highlights trees and shrubs that have the highest survivability when transplanted in the SPRING.

Plants that were dug in the spring and kept in the garden center (e.g. root balls that are mulched or wrapped) generally have root systems that are further along in the recovery process and may be successfully planted in the fall.

Fall planting has the advantage of warmer soils, as compared to spring planting, with cooler air temperatures. During this time the roots can establish before the high heat of summer starts the following year. Ideally, before the soil freezes, soil temperatures remain above 40 degrees Fahrenheit for four weeks after planting. All species planted in the fall, especially conifers, require an ample water supply for winter protection.

Step 1: How do I know what to plant?  Starting out with…Tree selection

Step 2: How do I know if I’m getting high quality plant material?  Making the purchase… Buying high quality trees

Step 3: How do you plant?  Putting the plants in the ground…Planting the Tree
