Family: Elaeocarpaceae
Nepali Name: Rudraksha
Rudraksha is a sacred seed that is highly regarded in Hinduism and
Buddhism. It is believed to possess spiritual and healing properties. The
word "rudraksha" is derived from Sanskrit, where "rudra" means Lord
Shiva, and "aksha" means teardrop. According to ancient Hindu
scriptures, Lord Shiva shed tears of compassion for humanity, and these
tears crystallized into the seeds known as rudraksha.
Nepal is one of the primary sources of high-quality rudraksha beads.
The plant that produces rudraksha seeds, known as Elaeocarpus
ganitrus, is indigenous to the foothills of the Himalayan region,
including Nepal, India, and parts of Southeast Asia. In Nepal, the sacred
tree grows in the mountainous regions at elevations ranging from 700
to 1,500 meters above sea level.
The Nepalese region of Taplejung, located in the eastern part of the
country, is particularly renowned for its abundant supply of authentic
and high-quality rudraksha beads.

are initially green and turn bluish-purple or black when ripe.
Flowering: The flowering season typically occurs from April to May.
Fruiting: The fruits ripen in June.
No of Fruits per kg: 1000-2000 annually.
Conservation Status: Not evaluated
Germination: Soak the seeds in lukewarm water for 48 hours.
Fill a bowl with warm water from your sink so it's deep enough to
submerge the seeds you're planting. Pour the seeds into the water and
leave them to soak to help them germinate easier. After about 2 days,
drain the water and pat the seeds dry.
Methods of propagation:
The rudraksha tree (Elaeocarpus ganitrus) can be propagated through
various methods. Here are some common methods of propagating
rudraksha:
1. Seed Propagation: The most common and natural method of
propagating rudraksha is through seeds. The seeds are obtained from
mature fruits. It is important to collect ripe fruits and remove the pulp
before extracting the seeds. The seeds should be soaked in water for a
day or two to facilitate germination. After soaking, they can be sown
directly in prepared nursery beds or pots containing well-drained soil.
The germination period can vary and may take several weeks to several
months. Once the seedlings have reached a suitable size, they can be
transplanted to their permanent location.
2. Air Layering: Air layering is another method used for propagating
rudraksha. This method involves creating a wound or removing a ring of
bark on a branch of a mature tree. The wounded area is then covered
with moist sphagnum moss or a rooting medium and wrapped with a
plastic or polythene sheet to maintain humidity. Roots will develop at
the wounded area, and once they are well-formed, the branch can be
cut and planted as an independent seedling.
3. Grafting: Grafting is a common propagation method used for many
tree species, including rudraksha. It involves joining a scion (a young
shoot or branch) from a desired rudraksha tree onto a rootstock of a
compatible species. The scion is carefully selected to ensure the desired
traits, such as specific mukhi (facets) or high-quality seeds. The grafting
process requires skill and expertise to ensure successful union and
growth.
4. Tissue Culture: Tissue culture propagation is a more advanced and
specialized method used for mass production of rudraksha plants. It
involves taking small tissue samples from a selected plant and placing
them in a nutrient-rich culture medium under controlled conditions.
These tissue samples then develop into new plants, which can be
multiplied rapidly in a laboratory. Tissue culture propagation allows for
the production of genetically identical plants with desirable traits.
Each propagation method has its advantages and challenges. Seed
propagation is the most accessible and natural method, while methods
like air layering, grafting, and tissue culture require specialized
knowledge and equipment. The choice of propagation method depends
on factors such as the availability of planting material, desired traits,
scale of propagation, and expertise available.
Rate of Growth:
Generally, rudraksha is considered a slow-growing tree compared to
many other tree species. Here are some general estimates of its growth
rate:
1. Seedling Stage: During the initial years, rudraksha seedlings can have
a slow growth rate. In the first few years after germination, the
seedlings may grow around 15-30 centimeters in height annually.
2. Young Tree Stage: As the rudraksha tree matures, its growth rate can
increase. In the following years, the tree may grow around 30-60
centimeters in height annually. However, it is important to note that
growth rates can vary based on factors such as soil fertility, moisture
availability, and overall plant health.
3. Mature Tree Stage: Once rudraksha trees reach maturity, their
growth rate tends to slow down further. At this stage, the tree's growth
rate can range from 10-30 centimeters per year.
It is worth mentioning that rudraksha trees have a long gestation
period, typically taking 7 to 10 years to produce viable seeds. The
growth rate can also be influenced by the specific mukhi (facets) of the
rudraksha tree, as different mukhis are associated with different
growth characteristics and benefits.

Flowering: February
Fruiting: In the month of May
Conservation Status: Least concerned
Germination: Keep at between 20-25 degrees C. Seeds sometimes
germinate within 4 to 6 weeks although some may take very much
longer so please be patient. Plant out in the open ground in warmer
countries or in a large container elsewhere.
Method of Propagation:
1. Seed Propagation: Propagation from seeds is one of the most
common methods for growing peepal trees. The ripe fig-like fruits
(syconia) are collected from mature trees. The seeds are extracted from
the fruits and washed to remove any pulp or debris. Peepal seeds have
a hard coat and are often treated to enhance germination. Scarification,
which involves nicking or scratching the seed coat, can be done to
promote better water absorption. Soaking the seeds in water for a few
hours or overnight can also help in softening the seed coat. Once
prepared, the seeds are sown in well-prepared soil or seedling trays.
Adequate moisture and warmth are provided for germination, and the
seedlings are transplanted to their final growing location when they are
of sufficient size.
2. Vegetative Propagation: Peepal can also be propagated through
vegetative means, which involve using plant parts other than seeds.
Some common vegetative propagation methods for peepal include:
a. Stem Cuttings: Select healthy, mature stems and take cuttings
around 20-30 cm in length. Remove any leaves from the lower portion
of the cutting. Dip the cut end of the stem in a rooting hormone
(optional) and plant it in a well-draining rooting medium. Maintain
humidity around the cutting by covering it with a plastic bag or a
propagating dome. Provide warmth and indirect light. Over time, the
cutting develops roots and can be transplanted into a larger container
or directly into the ground.
b. Air Layering: Air layering is another effective method for
propagating peepal trees. Select a healthy branch and make a shallow
incision or remove a small section of bark. Apply a rooting hormone to
the exposed area. Wrap the wounded section with moist sphagnum
moss or another suitable rooting medium. Cover the moss with plastic
wrap or a plastic bag, sealing it at both ends. Roots will develop within a
few weeks or months. Once the roots are well-formed, the branch can
be cut below the rooting zone and planted as a new tree.
c. Grafting: Grafting can also be used for propagating peepal, although
it is less commonly practiced compared to seed or stem cutting
propagation. Grafting involves joining a desired peepal cultivar (scion)
onto a compatible rootstock. The scion is carefully selected, and a cut is
made in the rootstock to match the scion's shape. The scion is then
inserted into the cut area and secured in place with grafting tape or a
similar material. The grafted tree is protected and maintained until
successful union and growth occur.

5.Dhupi Salla (Juniperus indica)
Family: Cupressaceae
Nepali Name: Dhupi
Juniperus indica, commonly
known as the Himalayan
juniper or Dhupi in Nepal, is a
species of juniper native to the
Himalayan region, including
Nepal. This evergreen tree is
highly adaptable to diverse
environments and can be found
in various habitats, from high altitude alpine zones to lower elevations.
Juniperus indica is characterized by its dense, conical or columnar
shape and its aromatic foliage, which releases a distinct resinous scent
when crushed. The leaves are scale-like, arranged in opposite pairs or
whorls, and often have a bluish-green hue. This species is dioecious,
meaning that male and female reproductive structures are found on
separate trees. The female trees produce small, round, bluish-black
berries known as "juniper berries." These berries are used in traditional
medicine and as a spice in culinary applications. In Nepal, Juniperus
indica holds cultural significance and is often found in sacred groves
and as a component of traditional healing practices. The tree is also
valued for its timber, which is used in construction, furniture making,
and as fuelwood. Juniperus indica is an important component of the
Himalayan ecosystem, providing habitat and food for various wildlife
species and contributing to the overall biodiversity of the region.
Silvicultural Characteristics:
Juniperus indica is a slow-growing, evergreen tree that typically exhibits
a conical or columnar growth habit.
It is a shrub growing to 50-200 cm tall, with largely horizontal
branching. The leaves are dark grey-green, dimorphic, with adult plants
having mostly scale-like leaves 1-3 mm long, while young plants have
mostly needle-like leaves 5-8 mm long, but needle-like leaves can also
be found on shaded shoots of adult plants.
The leaves are borne in whorls of three on strong stout main stem
shoots, and opposite pairs on thinner, slower-growing shoots. It is
dioecious, with male (pollen) and female (seed) cones on separate
plants.
The mature seed cones are ovoid, berry-like, 6-10 mm long, glossy
black, and contain a single seed; the seeds are dispersed by birds which
eat the cones, digest the fleshy cone pulp, and excrete the seeds in
their droppings
Himalayan juniper is highly adaptable and can tolerate a wide range of
climatic and soil conditions. It is commonly found in the Himalayan
region, including Nepal, at various elevations ranging from lower hills to
alpine zones. It can withstand harsh environmental conditions such as
cold temperatures, high altitudes, and rocky terrain
Juniperus indica plays a crucial role in the Himalayan ecosystem. It
provides habitat and food sources for various wildlife species, including
birds and small mammals. The dense foliage of the tree also offers
shelter and protection for animals. Additionally, the tree's deep root
system helps stabilize soil and prevent erosion in mountainous areas.
Field Identification:
1. Tree Size and Shape: Juniperus indica is a medium to large-sized
evergreen tree that can reach heights of up to 20 meters (65 feet). It
has a dense, conical or columnar shape with a rounded crown.
2. Bark: The bark of Juniperus indica is reddish-brown or grayish-brown
and develops shallow furrows and ridges as the tree matures. The bark
texture is often smooth on young branches but becomes rougher and
more fissured on older branches and trunks.
3. Foliage: The foliage of Juniperus indica consists of scale-like or
needle-like leaves that are arranged in opposite pairs or whorls along
the branches. The leaves are often bluish-green or grayish-green in
color and give off a pleasant resinous aroma when crushed.
4. Cones: Juniperus indica produces small cones that are typically green
when young and turn bluish-black or dark purple when mature. The
cones are berry-like in appearance and have a fleshy texture with a
waxy coating. They contain seeds and are often referred to as "juniper
berries."
5. Habitat and Distribution: Juniperus indica is native to the Himalayan
region, including Nepal. It can be found in various habitats ranging from
high-altitude alpine zones to lower elevations. It is often found growing
in rocky areas, slopes, open forests, and grasslands.
6. Geographic Range: Juniperus indica is primarily found in the
Himalayan region, including Nepal, India, Bhutan, and parts of China
and Pakistan.
7. Aromatic Resin: When the foliage or branches of Juniperus indica are
crushed or bruised, they release a characteristic resinous scent, which
is a notable feature of this species.
Flowering: early Spring
Fruiting: The cones are seen in April to May that mature in October
to December.
No of Fruits per kg: 1000-3000
Conservation Status: Least concerned
Germination: Seed dormancy in this species is broken by warm-cold
stratification at 15°C/3°C, for 14+12 weeks, respectively. Seed drying
for 72 h at room temperature in the middle of the warm phase (i.e.
after 4-8 weeks of stratification at 15°C) and the following cold
stratification at 3°C, cause a significant increase in seed germination
capacity at cyclically alternating temperatures of 3~15°C, and in
seedling emergence in growing trays (67 cells each) in a greenhouse.
However, seedling emergence was over 2-fold to 4-fold lower in an
open nursery than in the greenhouse.
Methods of Propagation:
1. Seed Propagation: Propagation through seeds is the most common
method for Juniperus indica. Collect mature seeds from the tree during
the fruiting season. Soak the seeds in water for a few hours to soften
the seed coat and enhance germination. Sow the seeds in well-draining
soil or a seedling tray, covering them with a thin layer of soil. Keep the
soil consistently moist and provide warmth and light. Germination may
take several weeks to a few months. Once the seedlings are well-
established, they can be transplanted into larger containers or directly
into the ground.
2. Stem Cuttings: Juniperus indica can be propagated through semi-
hardwood stem cuttings. Select healthy, mature branches and take 10-
15 cm (4-6 inch) long cuttings. Remove the lower leaves and dip the cut
end in a rooting hormone to promote root development. Plant the
cuttings in a well-draining potting mix or rooting medium, ensuring that
at least one or two nodes are below the soil. Keep the cuttings moist
and provide a warm and humid environment. Rooting can occur in a
few weeks to a few months, and once rooted, the cuttings can be
transplanted to larger pots or the ground.
3. Layering: Layering is another method to propagate Juniperus indica.
Select a healthy, low-growing branch and bend it gently to the ground.
Make a small incision or remove a small section of the bark where the
branch touches the ground. Cover the wounded area with soil, leaving
the tip of the branch exposed. Secure the branch with a stake if
needed. Over time, roots will develop at the wounded area. Once the
roots are well-established, separate the rooted section from the parent
plant and transplant it.
4. Grafting: Juniperus indica can also be propagated through grafting,
although this method is less commonly used. Select a suitable rootstock
and a scion from a desired Juniperus indica tree. Perform the grafting
technique of your choice, such as whip grafting or cleft grafting,
ensuring proper alignment and secure attachment. Protect the graft
union with grafting wax or tape. Provide appropriate care and
monitoring to ensure successful grafting.
