There are basically two types of tree seedlings; plug and container. Plug tree seedlings are grown in nursery trays usually 100 or more to a tray. Plug tree seedlings are grown close together in tray cavities where roots grow and form an elongated plug ranging 3 to 12 inches in length. Because tree tray cavities are small, plug seedlings are grown for only 2 or 3 years. The forest replanting industry uses plug seedlings. Container tree seedlings are grown in round plastic containers ranging from 1 to 20 gallons in size. Containers allow nursery owners to grow trees for a number of years in the same container, up to 10 if necessary. Container tree seedlings are typically sold via the public retail market by nurseries.
Plug & Container Disadvantages
Typically, plug tree seedling root systems are under developed, which lessens the probability that the seedling will take to its new earthen surroundings after transplant They are also short, typically no more than 12-inches tall, which makes the tree susceptible to deer grazing and winterkill. Container tree seedlings are big and bulky; difficult to transport and transplant. Over time, root systems will form to the shape of the container forming a root ball. A tree seedling with a root ball will need after transplant supports to protect it from potential damage from wind blow.
Growing Tree Seedlings
Tree Plantation tree seedlings are grown in two stages; seedling and sapling. Seedlings are propagated from seed using our patented multi-tree tray, which promoted early root development. After two years, they are harvested and transplanted in field where they are manipulated to grow tall using another patented propagation system, which encourages top vertical growth. After 5 the saplings are harvested, shipped and transplanted in a tree plantation.
Planting Tree Seedlings
Plug tree seedlings are planted by hand or machine. Hand planting is necessary in stepped terrain. Mechanized planting is the preferred method where the land is generally flat. Tree Plantation tree seedlings are planted using a PTO mounted on the back of tractor. Using a similar technique as one would use for fence posts, vertical holes the width of the auger (which should be a little larger diameter than the root stem) are drilled into the ground spaced far enough apart for a particular tree species planted. Black walnut would be spaced farther apart than Yellow birch for example. As each hole is dug, a tree seedling is inserted and backfilled by hand.
Tree Plantation tree seedlings are good for the environment, stop the encroachment of deserts, reclaim land, capture carbon, reduce pollution and make more money, faster.
