PInus tecunumani (Red pine)

Viable seeds / kg (approx.): 52,700

Minimum purchase: 100 g


Red pine occurs naturally from
Mexico to Nicaragua, but it has been planted extensively in many countries of
the tropics and subtropics. It can reach heights of up to 55 m and diameters (DBH) of
50-90 cm with a straight stem free of branches up to 40-60% of its height. It
is considered the pine with the best stem form of all the pines of Mexico and
Central America.


P. tecunumanii has a great potential for
reforestation in pure plantations, agroforestry systems and boundaries. It has
also been used as ornamental. The wood is moderately heavy, yellowish brown,
fine texture, straight grain, versatile, used for heavy construction, interior
construction (doors and window frames), treated posts, plywood, furniture and
handicrafts. As an exotic species, the species has been planted mainly for the
production of sawn wood, poles and pulp for paper.

Environmental conditions

Red pine can grow over a wide altitudinal
range, from 440 to 2800 masl, with mean annual rainfall from 790 to 2200 mm and mean
temperatures of 14 to 25ºC.


It grows on a wide variety of
soils, moderately fertile and deep, slightly acidic to neutral (pH 4.8-7) and
well drained.

Seeds and nursery

As a pre-germination treatment it is recommended to soak the seeds in
running water at room temperature for 12 hours. For the seedbed, a loose
substrate such as river sand should be used, well washed and disinfected. The
seed must be distributed evenly or in rows separated by 2 cm, sowing
superficially (2 mm). Germination occurs after 8-17 days and transplanting must
be carried out when the seedlings have reached 3-8 cm in height. The root is usually
very long, so it must be pruned to about 3-4 cm in length. When transplanting, be
sure to make a hole deep enough in the substrate to avoid curving up of the
roots. Shade should be provided for the first 2-3 weeks after transplanting,
for instance using shade clothing (saran) 50%. If the nursery is new or if the
soil has been sterilized, it is essential to inoculate the plants with mycorrhizae;
otherwise they will hardly grow and will become yellow and weak. For the
inoculation, surface soil from a well-established pine forest can be used,
mixed with the substrate used in the nursery, or by irrigating the plants
several times after transplanting with a spore solution of the fungus. Plants
properly inoculated will be ready for field planting after 5-6 months, when
they have a height of 25-30 cm. A couple of weeks before planting out in the
field it is recommended to reduce watering to stimulate the lignification of
the stems.


Red pine is an outstanding species,
with excellent phenotypic and silvicultural characteristics, fast growth and
excellent stem form. In trials in Costa Rica, it showed better growth than all
provenances of P. caribaea. At 7 years
of age, it showed heights between 13.6 and 18.3 m (Mean Annual Increments (MAI) of 1.9 - 2.6 m), and between 16.3 - 25.3 cm in diameter (MAI = 2.3 - 3.6 cm). In other trials at the age of 6.5 years, MAI in
volume varied from 15.8 to 31.9 m3 / ha / year.
