How to Take Care of a Bonsai Tree
Bonsai is a special art form that is used to create dwarfed trees and is loved by many. These trees have been used for centuries as part of the décor in many traditional Japanese homes. In recent years, bonsai trees have gained mainstream notoriety as a great touch to a modern home.
If you are a first-time bonsai owner, then you will definitely need some tips on how to care for this special plant. This is because these trees are unique plants and require equal care. Here are some basic guidelines for growing and maintaining your bonsai tree.
Aspect of Care:
5 to 6 hours of direct sunlight. This requirement can change based on the variety of Bonsai and if the light received is direct or indirect.
Water when the top 1-1.5 inches of soil is dry. Water enough to soak to the bottom of the pot. Never allow the soil to dry out completely.
Use a "Conifer Blend" or other Bonsai specific potting soil.
Every 1 to 5 years depending on the Bonsai. Pale yellow leaves = time to repot.
You must use fertilizers with Bonsai's. Use a fertilizer specifically formulated for Bonsai trees. Fertilize year round for an indoor tree.
General Care Tips
Regular light pruning is recommended.
Bonsais need approximately 5 to 6 hours of direct sunlight each day. If your tree is in a location where sunlight is not very intense, you can increase the number of hours your tree receives sunlight to compensate (up to 16 hours of daily sunlight). If you move your tree from an area with low light to more intense, direct light, do so gradually to avoid damage to your tree. Avoid artificial (incandescent) lighting as this will not provide the spectrum of light needed for your bonsai to develop.
Since environmental factors continuously change based on the season and time of the day, regularly changing the location of your tree would be the most appropriate approach in balancing lighting, humidity and temperature.
One of the most challenging aspects when it comes to care and maintenance of bonsai is to establish when and how you should water the tree. It’s important to note that, generally, water requirements will depend on a number of factors including: if it is summer or winter, number of hours of sunlight exposure, the specific variety of bonsai, soil conditions, and the size of the bonsai.
Since there isn’t a general formula that can be used to dictate watering frequency, you should always monitor the condition of the top soil. If the top 1 to 1.5 inches of top soil feels dry, it is probably time to water your plant. This can be once every day or once every few days depending on the above-mentioned factors. Over time you will get to where you will know what your bonsai requires.
Here are some general guidelines for watering of your bonsai tree:
- Regularly monitor the dampness of the plant's soil by pressing your finger into the dirt, taking care not to damage any roots.
- It’s recommended to water the plant during the morning hours.
- During the summer or during warmer days, your bonsai will require more water.
- Water no more than once a week during winter season: too much water isn’t good for the bonsai during this dormant season.
- If sunlight exposure decreases, watering requirements will also decrease. If sunlight exposure increases, watering requirements will increase.
- Water the tree at regular intervals during the growing season so your bonsai can adapt to the watering schedule.
It is very important to choose bonsai-specific soil for your tree. Consider a soil mixture such as a "Conifer Blend" that has the correct texture as well as uniform distribution of ingredients.
A good potting soil is one that encourages maximum aeration and water drainage. It will allow standing water in the soil to drain out while still retaining some moisture for the plant. Remember to use soil that has an appropriate pH value, preferably 6.5 to 7.5.
In order to provide an environment that triggers the tree’s growth and development, it is necessary to regularly repot your plant. The most ideal time to transfer your bonsai to another pot is immediately after winter. This is because these plants store a lot of energy in the roots during the dormant season and use it for growth as soon as summer begins.
Generally, repotting is necessary every 1 to 5 years. Fast growing or younger trees will need repotting more often (about once a year) whereas older trees will require it less often (closer to 5 years).
There are a few other indicators that will help you establish that it’s time to repot your bonsai tree.
- The plant’s leaves begin to turn pale-yellow and young ones emerge.
- Bud formation on the stem is observed. If this occurs, prune the plant’s roots prior to repotting.
Use of Fertilizer
These decorative plants are normally grown in small pots and therefore rely on fertilizer more heavily than many other house plants.
Generally, potassium, nitrogen, and phosphorous fertilizers are good for the bonsai plant as they are responsible for the green color of leaves, root development, and flowering. It’s advisable to buy a bonsai specific fertilizer from a reputable distributor. Keep to the following guidelines in order to give your tree the best care:
- For outdoor trees, fertilize during growing periods.
- Indoor trees, require regular application of fertilizer throughout the year.
- Regulate nitrogen usage during summer and dormant seasons.
While some people prefer to call experienced gardeners for the pruning, shaping and wiring of the bonsai trees, it is something you can easily do yourself. Even though maintenance pruning can be done at any time of the year, structural pruning is best when the plant begins to grow after the dormant period. Remember to use sharp pruning tools in order to avoid inflicting damage to your tree.
In order to get the best shape for your plant, only cut off branches and shoots which seem to have gone beyond the desired canopy. For better results, structural pruning should always be followed by accurate wiring.
There is nothing more beautiful than a well cared for bonsai tree. Take the time to care for your tree properly and it can last you decades.
