Indoor: The mid-winter time period can be a crucial time for your indoor bonsai. This is often a period when there are many more cloudy days than sunny ones and trees at windows are receiving
very low light levels. These trees will be doing little, if any, growing. There also may be some yellowing or dropping of leaves due to the low light. Do not fertilize trees that are placed at windows. Also be aware that there can be cold drafts through the glass itself. You may
need to move these trees back from the window on cold days and, in particular, on cold nights. Low indoor humidity levels can also cause problems. If possible, it is a good idea to move these trees
to a location close below a fluorescent light fixture or place a light near the trees at the window to supplement the meager natural light. Placing a humidifier in the area near the trees will help alleviate the problems associated with low humidity. Trees growing exclusively under fluorescent light may be fertilized if they are putting out new growth. Pinch or trim back any leggy, soft growth.
Outdoor: Watch that these trees do not dry out too severely.
Water or pile snow over the roots.
General: Plan ahead for spring. Clean and sharpen tools, Replace
broken or damaged tools. Look for pots that you may need this
spring. Check out books and magazines for styling and care ideas.
