Most pine regeneration in the Southern United States is accomplished by planting. The objective of this
circular is to provide information on the steps involved in successfully planting southern pine seedlings. Some
of the steps included are preparing the site, purchasing seedlings, transporting and handling seedlings, plant-
ing, checking planting quality and evaluating success. In addition, information on the costs of regeneration
practices and information on where to obtain financial and professional forestry assistance is provided.

In a recent survey, landowners were asked to iden-
tify the most important reasons for owning forest pro-
perty; the top answers were wildlife, beauty, heritage
for future generations, firewood and timber needs,
recreation, hunting, and future investment [7]. All
these contribute to the importance of establishing a
forest stand on a parcel of land. In addition, by plant-
ing trees, a landowner can help provide the future
wood supply of our nation.
In the South we are presently regenerating less than
half of the acres that are harvested each year. Because
of this, trends show that our forest land is being
depleted, and the supply of wood from these forests
will not meet the growing demands of the nation in
the future unless we plant trees now. Because 60 per-
cent of the forest land in the United States is owned
by nonindustrial private forest owners, these land-
owners are extremely important to our future forests.
Most pine regeneration in the South is accom-
plished by planting. The objective of this circular is
to provide information on the steps involved in suc-
cessfully planting southern pine seedlings. Although
pine regeneration is not difficult to accomplish, to be
successful it does require advanced planning and
careful implementation of each of the steps. When
considering alternatives for each of these steps, it is
a good idea to seek the advice of a professional
forester such as your county forester or a consulting

tional opportunities (top) and grazing areas for
livestock (bottom).

If you have land that is idle, nonproductive, or has
recently been harvested, pine trees are a good crop
to consider planting. The trees are not expensive ($20
to $50 per 1,000), and management costs range from
$3 to $5 per acre per year. Also, tax benefits and other
incentive programs for tree farmers are provided by
the Agricultural Stabilization and Conservation Serv-
ice (ASCS), Soil Conservation Service (SCS), and
Florida Division of Forestry. These incentive pro-
grams are particularly helpful in lowering the costs
of site preparation and planting.
The potential returns from pines in a 20-year rota-
tion may range from $400 to $1,500 per acre. In
addition to substantial economic returns, a forest
stand provides recreational areas for picnicking, hik-
ing, and hunting for family members, guests, and
visitors (Figure la). Many tree farmers also use the
forested areas to graze livestock (Figure Ib); however,
animals should not be allowed on planted land until
the trees are large enough to withstand cattle distur-
bance. Planting trees also may help control soil

Much of the work of planting trees can be a family
project accomplished in spare time. However, for large
acreages or where competing vegetation must be
eliminated, mechanical equipment will be needed for
site preparation and planting. Whether landowners
use their own farm equipment or contract with others
to do the work, these additional costs need to be
Regeneration costs will include (1) cost of the seed-
lings and (2) costs for practices such as site prepara-
tion, planting, and site maintenance. (See the sections
on each of these practices and see Appendices A and
B for approximate costs.)
Keeping good records is an essential part of
regeneration and land management (Figure 2).
Reliable information on the timing and costs of prac-
tices will help the landowner during tax preparation.
Also, if problems with regeneration occur, the infor-
mation may be useful in problem solving, and when
another parcel of land is regenerated, the information
may be useful in regeneration planning.

Many agencies provide technical and financial
assistance to landowners interested in planting trees.
The Agricultural Stabilization and Conservation Serv-
ice (ASCS) administers federal incentive programs.
The Soil Conservation Service (SCS) provides
management planning and technical assistance. The
Florida Forestry Association administers the tree farm
program. The Florida Division of Forestry, through
your county forester, provides management planning
and technical assistance. Your county extension agent,
of the Florida Cooperative Extension Service, pro-
vides educational and technical information on plant-
ing pines and managing your forest land (Figure 3).

FIGURE 3. The extension agent in your county
provides educational programs, such as this
demonstration on tree planting, and materials
which help landowners learn about planting trees
and managing their forest land.


One of the first decisions to be made is what tree
species to plant, and in Florida, there is a choice of
four major pine species: loblolly, slash, longleaf, and
sand pines. Although selecting the right species
depends to some extent on the final product desired,
the soil condition on the planting site is one of the
biggest factors determining what species to plant
(Figure 4).
It is a good idea to see what other landowners are
successfully planting and to look at other forest
stands nearby and on similar sites to see which
species are doing best. Also, your county forester will
be familiar with the benefits of growing particular
The two Florida Division of Forestry nurseries and
commercial nurseries grow seedlings for your area.
It is desirable to buy genetically improved seedlings,
even though they might cost a little more. "Improved"
means that they have been selected because they are
better growers or because they are more disease resis-
tant (Figure 5). In areas which have a disease problem
such as fusiform rust, purchasing rust resistant seed-
lings will be beneficial.

FIGURE 4. How to select the appropriate species
for planting, based on soil characteristics.

Pine seedlings should be ordered as early as possi-
ble before the planting season (November to
February). Seedlings may be purchased from Florida
Division of Forestry nurseries or privately owned
nurseries. To find out where to order trees in your
area, call your county forester. Place your order as
soon as possible because often there may be a limited
number of seedlings available. Select a date for
delivery and pick-up of your seedlings which closely
coincides with the planting date, because the longer
the trees are kept out of the ground, the lower their
survival rates will be after planting.

FIGURE 5. Genetically improved trees grow bet-
ter than unimproved trees. The two trees in front
of the geneticist are improved; the two trees in back
of him are unimproved trees.

Two types of seedlings are planted in the South:
bareroot seedlings grown in soil in nursery beds and
containerized seedlings grown in small containers
(Figure 6). Most planting is done successfully with
bareroot seedlings. However, containerized seedlings
may be beneficial under some planting conditions.

Containerized longleaf pine seedlings may have better
survival rates because of their protected, undisturbed
root system. Containerized seedlings may perform
better on adverse sites. Also, the planting season can
be extended (past the normal November to February
season) using containerized seedlings if soil moisture
and weather conditions are favorable [1].

FIGURE 6. A containerized longleaf pine seedling at a container nursery in Florida (left), and a slash
pine bareroot seedling at an outdoor forest tree nursery in Florida (right).

There are two main objectives for preparing the site:
(1) to remove the slash and other plant debris to
facilitate planting, and (2) to eliminate unwanted
vegetation which will compete with newly planted
trees for water, sunlight, and nutrients (Figure 7).
Three major methods of site preparation include
use of (1) a prescribed fire, with either a broadcast
burn or the burning of piles after mechanical site
preparation; (2) mechanical site preparation, which
may involve chopping, disking, shearing, raking, pil-
ing, or bedding; and (3) chemical herbicides. One or
any combination of methods may be effective on a
particular site. (For more details on site preparation,
see IFAS Fact Sheet FRC-37 [3].) The ideal methods
are those which cause minimal site disturbance, clear
slash and competing vegetation best, and have the
lowest cost [3].

Many Florida soils need additional nutrients for
optimum tree growth. Two soil groups (A and B) estab-
lished by the Cooperative Research in Forest Fertiliza-
tion (CRIFF) program at the University of Florida need
fertilizer at the time of planting (Figure 8) [5]. Land-
owners should determine if the soil on their land
belongs to a soil series in either of these groups; soil
series maps are available in your county extension
office or ASCS office. Useful information on the forest
soils of Florida is available in Fact Sheet FRC-33 [4].
Fertilizers should be incorporated at the time of site

Soil groups: A and B

protected from temperature and moisture extremes
at all times. During transportation, seedlings should
be covered to prevent drying or overheating. A refrig-
erated truck or cooler (34 to 36 o F) is best; if this is
unavailable, seedlings should be covered to protect
them from the sun and wind (Figure 9).

FIGURE 7. Removal of logging slash and vegeta-
tion on the planting site will facilitate planting and
result in better establishment of seedlings. On this
site piles of slash and vegetation will be burned
before planting.

FIGURE 9. (a) and (b) Seedlings are often loaded and transported in a refrigerated truck. (c) and (d) Seed-
lings can be loaded in a pickup for short-distance transportation; they should be covered with a reflective
tarp to avoid wind, sun, and heat damage.

Try to avoid physical damage to seedlings by han-
dling them carefully and as little as possible. Keep
seedlings out of direct sunlight. Longleaf and sand
pine seedlings are extremely perishable and should
be planted as soon as they are received. It is best to
plant loblolly and slash pine seedlings within a week,
but if you must store them, refrigerated storage (34
to 36 o F) conditions are best. If cold storage facilities
are not available, store seedlings in a cool, shady
place. Seedlings which are in bundles should be
watered to prevent drying (Figure 10) unless they have
already been coated with clay or other absorbent
material. Avoid any exposure to freezing temperatures
- the roots are very sensitive and will die if frozen.

Seedlings may be planted either by hand or by
machine. Usually about 500 to 800 seedlings are
planted per acre for a pulpwood plantation. The rows
on the planting site are most often 10 to 12 feet apart,
and the seedlings are planted 5 to 8 feet apart within
the row. A 6- by 10-foot spacing will have 726 trees
per acre. (To calculate this: 43,560 ft2/acre 60
ft2/tree = 726 trees per acre.)
Seedlings are usually planted at the same depth as
they were at the nursery (with the root collar at the
ground line). Longleaf should be planted so that the
terminal bud is at or just below the ground line.
Usually a tractor and a mechanical planter are used
for machine planting (Figure 11). Before planting
begins, the following should be checked:

FIGURE 10. If it is necessary to store seedlings and refrigerated storage is unavailable, loblolly and slash
pine seedlings can be stored for a week in a cool, shady place. Seedlings should be watered to prevent

(1) The planter must make a furrow deep enough
for the entire root system.
(2) Spacing should be checked and regulated to
ensure desired spacing between each planted
(3) Depth of planting must be correct.
(4) Packing wheels should be properly aligned to
avoid running over seedlings.
(5) Shading and moisture need to be provided for
the seedlings carried on the planter.
On well-drained soils, the mound of soil created by
the planting machine may eventually wash away, and
seedlings should be planted 1 to 2 inches deeper to
account for this.
Tools commonly used for hand planting are hoe-
dads, bars, dibbles, and shovels (Figure 12). The hole
is made, and the tree is inserted with the root collar
at or slightly below the ground line (Figure 13). The
soil is then firmly packed around the seedling.

During the planting operation it is important to
check the quality of the planting. Check to make sure
that the depth is correct, the seedling is vertical and
firmly planted in the ground, and the roots are pro-
perly placed in the hole (Figure 14). To check if the
seedling is firmly planted, grab the seedling and
gently but firmly pull upward; if the seedling is too
loosely planted, it will come out of the soil. The place-
ment of the roots can be checked by carefully dig-
ging several seedlings with a shovel, observing the
placement of the roots, and then replanting them
before they dry out.

Too shallow


Four years after planting, southern pine seedlings
planted with complete weed control may be three
times as tall as seedlings growing in weeds (Figure
15) [2]. Weeds should be controlled for at least 2 years
following planting. Chemical herbicides, hand-cutting,
and mowing are three possible methods to control
weeds which surround seedlings. The newly planted
plantation should also be protected from grazing and

FIGURE 15. A tree with complete weed control
may be three times bigger after 4 years than one
with no weed control.

planting of seedlings.



For the first 2 years after planting, it is important
to assess the success of your planting efforts. If, after
2 years, the planting site has less than 300 trees per
acre, replanting will be necessary.
To estimate the number of trees on the site, one
1/100th-acre plot should be evaluated for every acre
planted; for greater accuracy, two plots per acre can
be sampled. In the following example, 24 plots were
sampled on a 24-acre planting site.
Follow these steps to establish a sample plot:

(3) Repeat steps 1 and 2 on every acre planted,
recording the number of trees for each plot on
a form.

(1)Anchor an 11.78-foot rope at a randomly
selected spot on the acre.
(2) After marking the starting point, walk around
in a circle (the rope is the radius), counting all
live trees within the circle.

After adding up the total number
of live trees on all plots, use formulas 1
and 2 to calculate the number of live
trees per acre. To calculate the survival
percentage of planted seedlings on the
site, use the estimated number of live
trees per acre (from formula 2) in for-
mula 3.

Total number Number Average number
of live trees of plots of trees per plot

Example: 132 + 24 = 5.5

Average number Estimated number of
of trees per plot x 100 = live trees per acre

Example: 5.5 x 100 = 550

Estimated Number Estimated
number of + of trees x 100 = percent
live trees planted survival
per acre per acre for site
Example: (550 + 700) x 100 = 79%
