Avoiding bonsai from losing leaves / falling off / turning yellow and dead branches
As we know bonsai are our beloved tree; that needs full time caring. If a bonsai is left with no care for a certain period of time, he might fell sick and die. In order to avoid your bonsai from losing leaves / falling off / turning yellow and dead branches, you need to proper care for it; to bear in mind those most important aspect in growing and caring bonsai (watering, light, humidity, temperature, air circulation, soil, fertilization).
Thus if it happens that your bonsai leaves turn yellow, there are some possible causes for that:
- First of all - some bonsai defoliate (drop leaves) when their environment changes. If upon the tree’s arrival some leaves have dropped or turned slightly brown that does not mean the bonsai is unhealthy. Defoliation is the natural result of being in the low-light environment of a shipping box. In some cases, Styrofoam popcorn must be used to safely pack unusually shaped bonsai. Organic popcorn packaging made from corn starch reacts with moisture from the trees and can dissolve. When you receive your tree, place the box in a shaded area to unpack. Inspect tree for damage to branches or leaves. Water soil if dry. Place each bonsai in protected shade for at least one week before moving to a sunny location.
Beside this natural cause, you could think to two more causes:
- First would be dehydration, which is the obvious choice. To remedy this, you need to consider feeding enough quantity of water (be careful not to drown your bonsai).
- The second possible cause is insect infestation. Meal bugs and spider mites are the usual culprit. Get yourself some plant-safe insecticides and get rid of the insects that plague your bonsai.

URGENT HELP PLEASE!
Hello,
so i have a juniper bonsai i have had for about 5 years now. He is beautiful and usually quite healthy, I live in Wisconsin where the winters are harsh and the climate change happens dramatically in Spring. I always take my Bonsai into a well sunlit room in winter and in spring i take it back outside. This spring however within the last week it has became progressively more and more yellow in color each day. I read your earlier post about how you should move it into a shaded area after being indoors which i didn’t do. I feel terrible. And will be completely distraught if i can not revive it. Is there away i can fix this problem? should i trim the yellow should i repot it? (it was repotted about two summers ago.) I’m moving it to shade as i type but i’m afraid it may be too late, please get back to me and help me figure a solution. I’m grateful of thee tips i have learned from this thread already i just need one more!

I also have a bonsai tree that leaves are now truning yellow and slowly dropping off after having it doing well for the last 5 years. I did trim the roots some and repotted it last fall with merical grow soil. There are signs of some new leaf growth, and I have always kept it inside at the same table when I bought it and brought it home. Can you please try to advise me on what you may think is the problem. Also the trunk of the bottom part of the tree has always looked darker then the rest and I have always gave it water when it first dries out, always trying to keep it most when needed. Could you please explain also to me about when and how to trim the roots and how often I may need to repot it. So many Thanks you for your help. This tree means so much to me as it was given to me from my boyfriend as a mother’s day gift to me in honor of my twin sons who were having to be away in the Army in Iraq and were unable to send me a Mother’s day gift. and I cherish it
Thank you so very much for your care and time in helping me.
with many good blessings to you,

I got my bonzai about a year ago. We’re thinking it’s either a Serissa or Segeretia. Its got very old bark, and it is suppose to have tiny white flowers that bloom (but never did). almost all the leaves have turned yellow, black or fallen. Please let me know what I can do, or if it’s too late to save my tree!! Thank you for your help!

Can you please help?
My tree has lost all of its leaves …

I was bought a bonsai tree for my birthday in jan. We had it inside for about a month before it started losing all of its leaves. I tried some different things and with watering it a little more it started to grow leaves again. I was still only watering once a week just more water at that time. Then in the beginning of april it started losing all its leaves again, we moved it outside since we were sure it wouldnt freeze anymore and the leaves turned brown and feel off faster. I still havent been about to get them to grow. Is it dead, or is there still hope for it?
