Bonsai Tree leaves have gone yellow can you advise?

Question

Hi I was given a Bonsai tree as a gift about a year ago (I am not a keen gardener by any means!)

The tree seemed to be doing fine new growth healthy leaves etc. I have been watering it every other day by sub merging it )over the roots) in a bowl of water for about 5 mins at a time and it was kept on my kitchen window sill with plenty of light and warmth.

A few weeks ago the temerature really dropped and it froze outside, the next day I noticed some of the tree's leaves (on the side next to the window) had gone yellow and started to drop off. I moved the tree in to my bathroom it's warmer in there and I thought the humidity would be good for it but the leaves are still turning yellow and dropping so it now has a bald patch!

So three questions really
a) Is the change in temp is the cause of this
b) how do I stop it
and
c) will I be able to save it

It was a gift for my birthday so has sentimental vaule and I don't want it to die! please help good people!

Answer 1

First of all what type of species of plant is the Bonsai??
All Bonsai are trees or shrubs of some type.
If the Bonsai is deciduous then at this time of year it is going to loose its leaves, but if its an evergreen then its most likely the temperature drop is why it is suffering. If its to close to the window the cold will effect the plant.
Move from the window to a place where it will get some sunlight, but unless you have heating all the time reduce the amount of watering during the winter months as the plant does not need as much during this time, even during other seasons, every 3 days sould be enough if you are soaking it. Liquid fertilising every 2 weeks during growth season.
Also you must consider that even Bonsai need to be re-potted and pruned both foliage and root systems regularly. So really as a novice they are very hard plants to care for.
Humidity like the bathroom is OK in some cases, but can also cause fungal disease with some species of plants and as I don't know what the plant is, I cannot advise on this but would not leave it there either if I was you.
Take your plant to garden centre and ask them for some advice, they should know what the plant is and advise you further. Or Maybe take it back to where it was purchased in the first place.
Dont give up just yet, I hope you can save it!!

Bonsai Tree Leaves Turning Yellow

Answer 3

Bone-Sigh [bonsia] means tree in a pot, so your first concern is:
What kind of tree are you growing. Any tree can be manipulated in the art of bonsai. So care given is given as to the species of tree you are culturing. Watering, location, etc... When you find this out you can respond with the proper requirements and become sucessful caring for it. To diagnose without looking at the tree is impossible to give advice. Good Luck

Answer 4

It's autumn! If it's a broad leafed tree, the leaves go yellow and fall off the same as the ones outside. Don't worry, it will grow new ones in the spring.

Answer 6

Too much water not enough sunlight and air find the spot outside where it gets the most sun and move it out there if you live in a cold state then cover it with clear plastic we keep ours in the greenhouse all winter and outside the rest of the year. good luck

Answer 7

A lot of Bonsai are like real trees, is it Autmn where you are? this could be the reason.

Answer 8

If you changed its location and orientation, that's not good. Was it outside before you watered it. Bonsai's are evergreens . It doesn't need water but once per week now. Don't do anything radical like change it from outside to inside, or reverse it's orientation. Let it dry out between watering's. You are lousing it.

Answer 9

1) could be deciduous
2) frost may have shocked it
3)fertilize with liquid seaweed - root drench and foliar spray

Answer 10

maybe its just loosing its leaves.... decidious

maybe it is lacking in nitrogen. put a little soluable fertiliser

maybe it is not geteing enough sun?
