Eucalyptus deglupta (Rainbow eucalypt)

Viable seeds / kg (approx.): 7,420,000

Minimum purchase: 25 g


E. deglupta is native to Papua New Guinea, parts of Indonesia and the Philippines,
but it has been successfully introduced to many parts of the tropics. It can
reach heights of 35 to 60 m in height, up to 70 m in some places, and diameters (DBH) of up to 200 cm, usually with a single, straight trunk. The stem shows different shades of color from green to
orange, which has earned it the name “rainbow eucalypt”.


The wood is reddish brown, of coarse grain, resistant but of little
durability in contact with the soil. It has been used for construction in
general, furniture, floors and treated posts for fencing and electrification.


It is a demanding species of light and is typically planted in pure
condition. In its natural distribution area, the mean annual rainfall is 2500
to 3000 mm, up to 5000 mm in some places. The maximum temperature near the
coasts is of 30-32ºC, with minimums of 24ºC in higher places. Outside its area
of ​​origin, it has been planted in equatorial regions below 1200 masl, with
annual rainfall exceeding 1000 mm without a pronounced dry season.


It prefers deep soils, of high average fertility, humid but with good
drainage, since it does not grow well in marshy soils.

Seeds and nursery

It does not require pre-germination treatments. Due to the small size of
the seeds, germinators should be used, with a loose substrate such as river sand,
well washed and disinfected, in which the seed is placed superficially, ensuring that it is not too piled up.
Germination occurs in a period of 5-12 days, reaching conditions for transplanting
1-2 weeks after germination. The root is usually very long, so it must be
pruned to about 3 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%. The plants will be ready
for field planting after 3 - 4 months or when they have a height of 15 to 20
cm. A couple of weeks before planting out in the field it is recommended
to reduce watering to stimulate the lignification of the stems.


E. deglupta is a very fast growing species, with annual increments of 1.1 to 4.9 m in
height and 0.7 to 4.5 cm in diameter. For
sawmill production, initial spacing should be at least 3 x 3 m. For production
of firewood, posts or tutors, high densities (up to 5000 trees / ha or more)
are used, generally with spacing arrangements from 1 x 1 m to 2.5 x 3 m.
