Pine Planting Methods: Should I use a Tree Planting Machine or Hand plant?
Once a landowner has site preparation complete, the big question is which planting method they should choose. Since planting pine seedlings improves the value of your land, you want to ensure that the job is done properly. Planting by hand and using a tree planting machine are acceptable. However, site conditions may only allow one or the other. The tract size, availability of contractors, amount of debris, contour, slope, and soil conditions are a few factors to consider as to which method will work best. The cost of each method should also be considered.
TREE PLANTING MACHINE
A heavy-duty, wildland pine tree planting machine can be used on cutover sites or fields. Limitations to machine planting would be land that is too steep, rocky, or wet.
How It Works
The planter is typically pulled with a bulldozer or large tractor. Bulldozers are equipped with a v-blade on the front to move debris, and clear a path if the site is rough. As the planter is pulled over an area, a coulter wheel cuts through the soil at a depth of approximately 12”. A planting foot is directly behind the coulter wheel and it creates a larger furrow for the tree seedling. If the land has been bedded, then a farm tractor with a conventional planter may be used. If it is too wet to support a heavy tree planting machine, it may be best to hand plant. Typically, the wildland planting operation is more costly than the conventional planter.
Some of the benefits of a tree planting machine include:
- Survival rates improve with machine planting
- Seedling handling is reduced and they are not exposed to wind or sun
- Machine planting fractures the ground. Cultivation from the coulter acts like subsoiling which promotes root growth
- Plant seedlings 2-3” deeper than they were from the nursery which increases survival
- Machine planting ensures that the soil is packed tightly; keeping the roots moist, promoting nutrient uptake, and the elimination of air pockets
- J or L rooting is greatly reduced with machine planting
- Planting sites have more consistent spacing and planting machines can generally plant upwards of 20 acres a day
Hand planting is conducted on sites that are not suitable for machines. Hand planting is practical on tracts that are rough with rocks, logging debris, or tall stumps. Hand planting may also be appropriate if the tract is too wet for tree planting machines.
How It Works
An individual hand planter can plant approximately 3-4 acres or 2,000 trees per day depending on site and weather conditions. Some container stock seedlings must be hand planted. Seedlings are generally sorted by the hand planter, before being placed in the “hip” seedling tote. Dibble bars, hoe-dads, or planting shovels are the tools of choice depending on the site. Some of the benefits of hand planting are:
- Lower cost than machine planting
- Facilitates planting steep hillsides and slopes
- Access to the entire tract
- Well suited for variable tract conditions such as hills and drains
Some seedling handling and planting challenges associated with hand planting are:
- Seedlings are exposed to the elements for a longer duration
- Human handling of seedlings can cause additional stress on young trees
- Planters may hand-carry too many seedlings which may cause desiccation
- J or L rooting may increase when planters are in a hurry or if the ground is hard
- Seedlings may be planted too shallow
- Hand planters sometimes trim or strip roots. A practice that is not acceptable
- Careful supervision is a must with hand planting crews
Machine planting cost: between $85 and $125.
Hand planting cost: between $50 to $80.

Customer Success Story: Jerry Merrill
“MCP and Varietals are all I will plant, I’m so happy with them. These trees have been phenomenal. Especially the Varietals. I believe, even though these trees are just 4 years old, we will easily be thinning in another 4 to 5 years. My bottom line is to create a dynasty to leave my family and this is the very best way I can do that.”
