Step by step instructions
1) Understand fast facts about Evergreen bonsai trees
Evergreen trees are mostly available in most countries. These trees are mostly green all year long hence the name evergreen. Evergreen trees do not lose their leaves but they lose their needles. These trees have a pleasing aroma making these perfect as Christmas trees and other yuletide decorations.
Evergreen trees may not lose their leaves but may gradually lose leaves throughout the year as the tree age and fall. Most tropical rainforests plants are considered evergreens.
Most warm temperate climate plants are also evergreen. In areas where there are cold climates, fewer plants are evergreen with a predominance of conifers as only a few evergreen broadleaf plants can tolerate severe cold climates.
In temperate climates, evergreen trees can adapt to the climate to survive. Evergreen leaf and needle may litter and have a high carbon-nitrogen ratio than deciduous leaf litter. An abundance of deciduous leaf litter can lead to increased acidity in soil and lower soil nitrogen content.
The most common image of an evergreen tree may look like a Christmas tree, however; these may vary greatly in their physical appearance and characteristics. Some evergreen trees like the California redwood can grow more than 350 feet in height.
Despite the name evergreen, not all trees have completely green leaves. Some have red, brown, yellow and other colors. Some coniferous evergreens like larches and pines have needle-like foliage. On the other hand, some have leaves, palms and other types of foliage.
Evergreen trees are composed of thousands of species including members of the families of cypress, fir, spruce, holly, eucalyptus, palm, hemlock, juniper, laurel, pine, rhododendron, magnolia, and redwood. The popular oak tree is also an evergreen tree.
Evergreen bonsai trees are miniaturized versions of regular-sized evergreen trees, these produce cones. The cones produced by bonsai trees are also smaller compared to regular ones.
And like large evergreens, bonsai cones also drop off at various times throughout the year and these contain seeds. Some species of evergreen that produce cones are juniper, silver fir, and spruce trees.
Evergreen trees are found all over the world especially in the cold regions of the Northern Hemisphere. Coniferous forests cover about 15% of the land on Earth and are composed mainly of evergreen trees like junipers, cedars, pines, and hemlocks. You will also find evergreen trees in the rich tropical rainforests in South America, sub-Saharan Africa, and East Asia.
Evergreen trees need full sun to thrive however some species may grow well even in the shade. Coniferous evergreen trees like dry, well-drained soils while evergreens found in rainforests love moist, soggy soils. Coniferous evergreen trees are more tolerant to cold and can live even in the coldest, habitable regions of the planet. On the other hand, rainforest evergreen trees thrive inconsistent warm temperatures.

Growing evergreen bonsai trees from seeds
Like most seeds, evergreen tree seeds germinate first before these are planted in a bonsai pot. Germination is when the taproot emerges from the seed and then afterward, the first small leaves and stems will appear from the open seed. It takes weeks for evergreen seeds to germinate and at this time, the seeds need sun and moisture.
But before you germinate seeds, you must first identify which seeds are good to germinate which ones are the opposite. You need a glass or a container of water to test for seeds’ readiness to germinate.
- Fill a glass or a transparent container with water.
- Place the seeds in the water and let it settle.
- Some seeds will sink while some will float. Take the floating seeds and discard these
- Take the seeds that have sunk and reserve these for germination.
Seeds that have sunk are seeds that are viable and contain viable insides that are ready to germinate. Seeds that float are empty or have no viable insides. These will not germinate no matter what.
After you have found which seeds will germinate and which ones should be discarded, it’s time to germinate your seeds.
- A large pot is needed to germinate seeds. Use a large but shallow pot to hold up to 4 seeds.
- Fill this large pot with peat seed sowing mix. This type of soil may be purchased from garden shops.
- Place the Evergreen bonsai tree seeds on the surface of the mix. Never cover the container because germinating seeds need sunlight.
- Water the soil to keep it moist. Water should run off the sides of the container to show that the soil has been completely soaked. Seeds need this to be able to germinate.
- Place the seeds outdoors in full sunlight.
- Keep the soil moist. Check your germinating seeds frequently and remember to keep the soil moist. These seeds will germinate for about a few weeks.
- You may transplant Evergreen bonsai tree seedlings to individual pots once these seedlings have gained strength. Remember that this tree will grow fast so it won’t be long when these seedlings will become young trees.
- Transplant these seedlings as soon as these are ready.
- A small and shallow bonsai pot is a good starter pot. The ideal planter pot should have two holes along sides and at the bottom of the pot.
- Initially place a layer of coarse substrate or aggregate. This will be the bottom layer that will remove excess water and fertilizer from the plant roots. This will also improve aeration of the soil to let oxygen to be absorbed in the roots.
- After the layer of aggregates, add bonsai potting soil. This is available in any garden center or bonsai accessories store whether online or offline. Choose a potting soil that will hold more water because Evergreen bonsai tree trees want moist soils.

- Water your young plants regularly to keep the soil moist. Never let the soil dry out.
Growing evergreen bonsai trees from cuttings
Cuttings are parts of a tree that when planted and cared for can grow into another tree. You can take cuttings from evergreen bonsai tree and grow another Evergreen bonsai tree.
This is very convenient because you will do without the wait of germinating and growing seedlings. But you just need to wait for the cuttings to develop thick roots before it could be planted. Here is how to get cuttings from Evergreen bonsai tree trees and cultivate them.
- Select a healthy Evergreen bonsai tree as a donor.
- This tree should be of good health. It must be growing new leaves and stems on a regular basis. This tree t must be free from molds and any pest infestation and no leaf discoloration.

Unlike other types of bonsai trees, evergreen types generally require much less pruning. This can normally be done in the fall since most of the tree’s growth occurs during the spring and summer months. When pruning this plant, it is important to use shears that have been cleaned and sterilized. Doing so prevents the spread of disease and fungus that could be harmful to an evergreen bonsai.
This tree requires regular fertilizing. The amount of fertilizer needed is generally higher during the spring and early summer months. During this time, adding a high nitrogen fertilizer twice a month is typically recommended. From mid to late summer, a regular fertilizer can be added once or twice a month. During fall and winter, the plant may need only occasional fertilizing.
Some varieties are able to thrive in filtered sunlight; however direct sunlight is recommended for most specimens of evergreen bonsai. As such, these plants should be placed in a sunny window that is free from drafts if grown indoors.

Keep in mind that wires must be applied carefully on Evergreen bonsai tree trunks. This should be removed on the same season it was attached as well.
Important wiring techniques
Wiring is a way to shape and style an evergreen bonsai tree. You will be able to style bonsai trees safely, effectively and quickly with wires. Wiring will reposition bonsai branches to the shape or style you want to achieve. There are a number of bonsai styles that you can use to shape this tree.
Shakan Bonsai Style
One of the most popular bonsai tree styles that may look great on an evergreen bonsai tree is the Shakan bonsai style. This is the slanted bonsai tree style which mimics a slanted tree in nature. The trunk of the bonsai protrudes from the soil in a slanted way while the rest of the tree straightens out in an outward manner.
The trunk is in a 60-80 degree angle that gives the trunk a slanted style. This style is achieved by strong wiring to control the growth of the main trunk. Wiring will control the height of the branch as well. Another way to create a slanted style is using strong lighting from one direction will bend the tree to create that slanted and windswept design.
The Dramatic Fukinagashi is like a windswept head of hair during a storm. An evergreen bonsai tree will look great in this exotic style. But despite how hard this design looks it can be more common especially for this type of tree.
In the Fukinagashi style, the branches and the trunk will grow to one side to recreate a realistic effect of strong wind blowing from one direction. This design is achieved by wiring the trunk carefully and pruning the leaves well to create that windswept plume.
Shari Bonsai Style
The Shari Bonsai Style is achieved by shaving the bark of the tree to keep new growth from appearing and reappearing. This style is also known as the stair effect because branches may be long or short.
The overall design is achieved through wiring and pruning. The leaves at the top of the tree make the design aesthetically balanced. The Shari bonsai style is actually from the natural development of trees and plants.
You may find a bald or barkless area on the trunk in a Shari bonsai style and this is because of the effects of harsh weather conditions.
Seki-joju or Rocky Terrain
The Seki-joju or Rocky Terrain style is showing off the lovely aerial roots of bonsai trees. It is all about growing bonsai roots around or through an obstacle. This could be anything in nature like a jagged or smooth rock.
This actually occurs in nature when roots of trees grow underneath and along the sides of nearby rocks. Roots are very adaptable and will also crawl around the rock surface and these happen as the trunk of the bonsai forms.
The rest of the tree will grow in a straight manner despite various obstacles along its path. The Rocky Terrain bonsai style is mostly done in trees that have good roots.
The Literati style is a bonsai style matches well with evergreen bonsai trees. This design has a skinny trunk and curved leaves. Bonsai enthusiasts agree that this style is all about the struggle in nature for even the smallest form of life to survive.
You will find a few bald spots along the trunk that will seem to look like dead branches. The Literati bonsai style is found in nature in trees that grow in densely populated areas like forests and woodland areas.
The Han-kengai bonsai style has a cascading effect wherein a section of the trunk grows straight as a branch grows outward and slightly downward. A small part of the trunk may be seen before the section where the thick branches grow.
These branches grow and develop in different directions and grow low-lying leaves. A bonsai with a Han-kengai design should have a deeper pot to maintain the style.
You must start wiring an evergreen bonsai tree as soon as it is strong. You may start wiring any time of the year. Apply wire carefully on the branches; apply this during the growing season or as the branches become thicker.
When you wire when the tree is mature, it can cut through the bark leading to ugly marks and scars. And of course, don’t remove the wire when it is due to be removed. Forgetting the time to remove the wires can badly injure your tree.
When the branches are wired, check your evergreen bonsai tree constantly. Remove the wires by cutting it piece by piece, turn by turn so you won’t risk injuring your plants.
The type of wire to use
Bonsai trees use two kinds of wires. You can use anodized aluminum and annealed copper. These can train bonsai plants but there are differences between the wires.
Aluminum is for deciduous trees which have harder and stronger trunks.
Copper wires are for species with harder trunks like conifers and pines.
If you are new to wiring use anodized aluminum wires because these are easier to bend and handle. This type of wire is also readily available anywhere. Wires are available in a variety of thicknesses and the most commonly used gauge is the 1 mm to 4 mm wires.
Wires may still cause injury to bonsai branches, especially for a young bonsai tree. Raffia is used to prevent injury in branches and trunks. Raffia is palm fiber available from garden stores.
This is soaked in water and wrapped along the tips of the branch or bark. Raffia will protect these from damage as a result of bending.
Step by step instructions on how to wire a bonsai
- Choose the type of wire for the type of tree that you are wiring.
- Choose the thickness of the wire you will use.
- Measure the length of wire that you need to use.
- Get one end of the wire and wrap this around the branch. Wrap it in a 45-degree
- Wrap the wire neatly in line along the extent of the branch.
- After you have completely wired the entire branch, cut the excess wire using pliers.
- Bend the branches into position. Do this to avoid damaging the plant or tree.
- To bring down branches that are too high, you may use a guy wire. Wrap moist raffia around the branch and place a hook at the end. Place a wire on the hook and anchor it on a strong root. This will keep the high branch lower.
- Check wired Evergreen bonsai trees regularly rapidly.
- Remove the wires during the same season.
- After wiring the branch, take note of the growth of your Evergreen bonsai tree. Place it in a shaded area of your garden and water it daily. Give balanced fertilizer that this tree needs.
Post-wiring care for your Evergreen bonsai tree
After wiring your Evergreen bonsai tree take note of these tips. Place the newly wired bonsai in a shaded area of your garden so it can regain its strength and bounce back to good health. Never leave it in direct sun because this can dry the soil so much. Give your newly-wired bonsai nutrients from balanced fertilizer so it can recover from wiring.
Don’t forget to remove the wires on schedule to avoid damage to the bark and branches. Do not remove the wire by loosening it but instead cut the wires at every turn. Never reuse the wire for wiring other branches as well. Remove wires at every turn by cutting it with pliers. Monitor tree health and let your bonsai tree rest before wiring and pruning it again.
9) How to prevent pests and diseases
Evergreen bonsai trees are prone to mold and root rot so don’t leave it overwatered. You must only water when the soil is dry and high and never when the soil is still moist. You must use the ideal pot for bonsai with good drainage to avoid root rot and mold growth.
You must also guard your evergreen bonsai trees against pests. The most common pests that can affect this kind of bonsai are caterpillars, spider mites and more. Don’t take pests for granted since one small bug means that there are more nearby.
