Forms in which plants are offered for sale:

 

Containerized/container grown:

- Containerized plants are the most widely sold plant material in nurseries and garden centers today.
- Before the plant is offered for sale, the roots should be firmly established in the container.
- When planting containerized plants, always remove the container at the planting site and disturb the root ball as little as possible.
- Container grown plants suffer very little transplant shock and can be successfully planted throughout the growing season.
- However, when you remove the container at the planting site, you may find the root ball to be very tight or even rootbound. The tighter the root ball, the more it should be disturbed before planting. Any roots circling the trunk or following the contour of the container should be cut to alleviate possible growth problems later.
- Never completely break up the root ball for either containerized or container grown plants.

 

Balled and burlapped (B&B):

- B&B plants are dug when dormant and are then held for planting throughout the season. It is usually the most expensive form in which plants are offered but it is very reliable when handled properly.
- B&B plants may be difficult to transport and plant without special equipment due to the weight of the plant and root ball. Consider having B&B materials delivered and/or planted at your site by your nursery or landscape professional to avoid damage to the plant.
- Roots of B&B stock will be seriously damaged if the soil ball is broken or damaged in any way or is allowed to dry out, so proper care and handling is extremely important.
- The soil ball around the roots of a B&B plant is normally held in place by burlap and twine or a wire basket. When planting, a wire basket may be left in place. However, if twine and burlap was used, you must cut and remove all twine from the
trunk of the plant and pull all the burlap away from the trunk and the top of the ball.
- When planting is complete, the burlap must be tucked well below the soil surface. If exposed, it will act as a wick and pull moisture away from the root ball and dry it out. Always make sure that the root ball on B&B stock has not been loosened or damaged in any way.

 

Field-potted:

- Field potted refers to plants that are grown in the field, then dug and placed in a container with the field soil intact around the root ball. It is very important that the root ball be disturbed as little as possible throughout the handling of fieldpotted plants.
- Since field soil does not make a good growing medium in a container, plants should not be held in field pots for long periods of time.
- When planting field-potted plants, always remove the container at the planting site before planting. While some containers may be biodegradable, this usually Field Potted occurs too slowly and will or containerized tree interfere with proper growth of the plant if not removed.

 

Bare root/packaged:

- Bare root plants are normally dug in fall or spring. The soil is removed from the roots of the plants and the plants are then held in controlled settings with cool temperatures and high humidity.
- While bare root is normally the least expensive, it will suffer most severely from transplant shock and has the highest mortality rate if handled improperly. It is extremely important that roots be kept moist and protected from sun and wind at all times during handling, transportation and planting.
- Bare root plants must be planted in early spring before the plant breaks from dormancy and growth begins.
- At the time of planting, prune away any roots or branches that appear to be diseased or damaged, but do not cut back healthy branches severely. As the buds on those branches begin in break, they will signal the roots of the plants to begin to grow.
- Packaged plants are simply bare root plants whose roots have been packed with a material such as peat moss. These should be handled in the same manner as bare root plants.
- It is very important that the packing material be kept moist and protected at all times.

 

Tree Spade:

- A tree spade is usually used for transplanting larger trees and greatly increases their rate of survival.
- When having a tree-spade tree planted, the matching planting hole must be pre-dug by the machine. The tree and its surrounding soil is then dug by the same machine which also transports it to the planting site and deposits it in the hole.
