Why Is Humidity Important For Bonsai? – Although indoor bonsai slow their growth in winter and do not need as much water, they still do require sufficient humidity. Humidity helps to reduce water loss through the processes of transpiration. Transpiration will have a negative effect on your bonsai’s ability to retain water and remain healthy.
How Can Humidity Be Improved? – The sometimes dry climate of a home or apartment can be altered to benefit your bonsai tree. Placing your bonsai on a "humidity tray" filled with decorative pebbles, that should be kept wet at all times, will help increase humidity levels. Another solution is regular misting. Misting is the most common humidifying method. It has the additional benefit of removing dust from your bonsai, which blocks sunlight and interferes with the exchange of oxygen and carbon dioxide. Be sure to mist using room temperature water to avoid shock.
What Else Is Helpful To Prevent Dry Conditions? – Keep your indoor bonsai trees away from breezy doors, windows and heating sources, such as vents, radiators, and fireplaces; to
avoid quickly drying them out. While more sunlight is desirable, it may dry out your bonsai. So, maintaining a watering schedule during winter is just as important as during summer.
Why Is Temperature Important For Bonsai? – During winter months it is vital that you keep your new indoor bonsai warm — Not Hot — but warm, somewhere between 50 and 70 degrees Fahrenheit. Where your bonsai falls on this guideline depends on where your bonsai is from "originally" and by this I mean where in the world your bonsai is indigenous… the warmer the native climate, the warmer the area in your home it should be located.
How Can Temperature Be Monitored? – The thermostat on the wall is a good place to start. However, a small thermometer can better monitor the actual temperature of the microenvironment that your bonsai tree is located in. Most garden centers will have small thermometers available for a reasonable price and purchasing a couple is a worthwhile investment, especially if your indoor bonsai are located in a couple different areas of your home.
What Is Helpful To Avoid Temperature Fluctuation? – Doors, windows, fans, heating systems and breezy hallways will all affect the actual temperature of a particular area. It is important for the health of your bonsai to be maintained at stable temperature. A sudden drop in temperature, as well as, a sudden spike in temperature can injure your indoor bonsai trees. Indoor bonsai should not be kept near a door that is frequently opened during winter months to avoid harmful cold drafts. It is important that you read the care guide that comes with your bonsai to help establish the best environment to maintain a healthy and thriving bonsai.
