Common Types of Pine Bonsai Trees
Even though every single type of tree or shrub can be crafted into a Bonsai tree, there are certain tree species that work better than others. But what are some of the most common types of pine Bonsai trees, and what might some of the differences between them be? Let’s take a closer look.
One-Flush vs Two Flush Pines
When it comes to taking care of your pine Bonsai tree, it’s important for you to know that most pine trees are categorized as either one-flush or two-flush pines. A flush refers to the growth habits of pine trees. One-flush pine trees only produce one growth per year, while two-flush pine trees produce two.
When shaping and pruning your pine Bonsai tree, it is important to know which type of Bonsai tree you have. If you have a one-flush pine tree, you risk damaging or potentially killing your specimen if you trim all of its growth. Choosing a two-flush pine tree is ideal for those of you that want to shape your tree twice per year, especially if you are interested in smaller needles.
A one-flush pine found throughout Europe, the Scots pine produces a unique reddish hue. The needles of the average Scots pine are thin and flexible, capable of shaping and twisting all on their own! The bark of the Scots pine tree is flaky and furrowed, making it a beautiful and detailed specimen.
Japanese Black Pine
With dark gray bark and bright green needles, Japanese black pines are some of the most popular two-flush pine Bonsai trees. Their needles are hard and paired in twos, making them fun to shape. Plus, with two growths during the year, your Japanese black pine will give you more shaping opportunities!
Japanese White Pine
There are many different types of dwarf Japanese white pine cultivars. While all white pines can be made into Bonsai trees, these dwarf options will be your best choice. With only one growth per year, Japanese white pines produce delicate foliage alongside textured bark. Many Bonsai artists pair Japanese white pines with Japanese black pines for strength and unique growth habits.
Japanese Red Pine
Another two-flush pine, Japanese red pines resemble Scots pines in terms of their foliage and flaky bark. Its trunks are typically narrow and sensitive, so shaping may take some extra patience and effort! These trees are native to the coastline of Japan, shaped and twisted by the wind and salt air.
A North American native, ponderosa pine trees make beautiful Bonsai specimens. They produce orange and red-tinged bark with large flakes and textural elements. They have a naturally upright growth habit given the fact that they are some of the tallest pine species in the world. However, shaping this species in a slanting or windswept Bonsai style may be a fun challenge!
Native to Europe, mountain pines grow well atop and amongst rocks. It produces dark bark and dark needles, making it an elegant and stately choice for the average home. Just like ponderosa pines, mountain pine trees are one-flush pines. While it may take a while to shape this Bonsai tree option, it’s well worth the effort!
Caring for Your Pine Bonsai Tree
One of the primary reasons why pine Bonsai trees may not be ideal for beginners is the fact that they need to be grown outdoors, in a very specific climate. While pine trees are frost-hardy and resistant to a number of diseases, Bonsai trees are fickle given their small size and container growth habits.
Besides needing to protect their roots in the wintertime, pine Bonsai trees get used to the climate that they are grown in. Changes to this climate affect the tree deeply, and you may find that some difficult weather conditions weaken your tree over time. If you have a particularly harsh winter, you may need to wait a full year in order to shape or adjust your tree’s growth habits! Here are some other tips when it comes to caring for your pine Bonsai tree.
Pine trees thrive in full sunlight, and your pine Bonsai tree will produce shorter, size-appropriate needles when given adequate sunlight. The needles will elongate and reach for more sun if your tree isn’t getting enough, often too large for the average Bonsai specimen. At least 5-7 hours of direct, outdoor sunlight is key for your pine Bonsai’s health and care.
All Bonsai trees need a special mix of their soil in order to grow and thrive properly, and a pine Bonsai tree is no exception. Choose a soil mixture of lava rock, pumice, Akadama, and organic potting mix for your pine Bonsai. Pairing your pine Bonsai with larger rocks may help with drainage and bring some desirable artistic elements to your pot or container!
Unlike a variety of other Bonsai trees, pine Bonsai trees don’t enjoy consistently moist soil. While daily watering is likely still necessary depending on the container that your tree is in, make sure that your soil is quick-draining. Water retention will kill your pine tree, especially the two-flush pines. In fact, excess water during the second growth period of your two-flush pine will likely produce large and swollen needles, something you don’t want in a delicate Bonsai tree format!
All pine Bonsai trees should be placed outdoors, in direct sunlight. If you are able, choose a location that is out of any rain or snowfall so that your tree does not get any excess water. In addition, you may need to move your pine Bonsai tree if it gets too cold, but try not to move it indoors if at all possible. Opt for some root protection or a greenhouse instead so that your pine can still experience its winter dormancy.
Pruning Your Pine Bonsai Tree
Shaping and pruning your pine Bonsai tree is an event that many beginners shy away from. In fact, pruning your pine Bonsai tree during the wrong season or too much may result in a weakened or dead tree, so care is necessary! Pruning is best accomplished in the fall when all new growth has stopped for the year.
One of the main things to consider when it comes to pruning a pine tree is the fact that they are full of sap and they will weep after being cut open. Petroleum jelly can help with stopping the sap. Otherwise, be sure to let your pine tree heal and dry its wound for a full year before pruning in the same location.
It’s important to note that young pine Bonsai trees can handle more intense pruning than older specimens, but it is still advised to take your time shaping your pine Bonsai tree, no matter its age. Pruning or cutting too intensely will result in a weakened or dying specimen as well as less growth in the long run. Be sure to leave the new growth on one-flush pines, as too much removal may kill these species.
Ideal Pine Bonsai Tree Styles
Given the upright growth habit of most pine tree species, a traditional upright style of shaping may suit them well. However, if you’re looking for a more artistic style for your pine Bonsai, a windswept or slanted style may also be gorgeous! Keep in mind that any pruning or shaping of your Pine Bonsai tree needs to be done with care, as continual damage to the tree will weaken it over time.
Propagating Your Pine Bonsai Tree
You can propagate a pine Bonsai tree from an existing tree, but with care and practice. Keep in mind that most Bonsai tree specimens shouldn’t be shaped for at least five years. A propagated tree may need longer, depending on how well it grows! No matter what, you can propagate your new Bonsai tree using a cutting from a pine tree of your choice, no more than five inches long.
Make sure to take your cutting using clean and sanitized shears. Remove the piece of branch in the summertime at a 45-degree angle and prepare a small pot with Bonsai soil. All you need to do is plant the pine cutting an inch down into the soil, water well, and wait! While roots form within a month, it may take some time to see growth from your pine Bonsai tree.
Common Problems with Pine Bonsai Trees
Grown outdoors, pine Bonsai trees are more susceptible to a number of pests and issues. However, sunshine and occasional monitoring for root rot typically keep these trees happy. Overwatering and cold weather aside, your pine Bonsai may experience trouble with pests such as:
- Caterpillars and other common bugs
- Spider mites
- Fungal infections
While pine Bonsai trees make great specimens for most climates, their delicate responses to pruning and shaping make them tricky for beginners. However, with practice, pine Bonsai trees are some of the most prized and rewarding trees to consider cultivating!
