10 Yr Old Cherry Bonsai - Leaves Changed Overnight

I just got it last week, its a 10 year old [url=]Surinam Cherry[/url] I've been watering it really well once a week keeping the soil moist, and it sits in the window seal here in Oklahoma on the west side of the house so it can get all of the sun while it is setting.

Almost over-night alot of the leaves are starting to look textured. I'm thinking I will get a grow light and start feeding it with miracle grow?

Thanks in advance for your advice.

Here are some blurry pictures I took with my phone, you can kind of make out the textured leaf look:

Hi Casey,
Welcome to the Helpful Gardener! :)

I'm not a bonsai expert, however if there is one thing I know, Miracle Gro is not the answer for your bonsai.

Someone should be along with some advice, so sit tight and let's see what the experts think about it.

Welcome to the site. Sorry I have no experience with this species so I don't know how much help I can be. In researching this question I found this article which you may not have seen yet.


This suggests that a window might not be an appropriate winter location for this species, especially in your area. The light level is probably rather low as well so I like the idea of moving it to an area with more even temperatures and supplemental lighting. A humidity tray certainly would not hurt either. This is a shallow tray substantially larger than the pot that has an inch or so of gravel in the bottom. Water is brought up to just below the top of the gravel and this combination helps to raise humidity in the immediate area of the tree. Since the tree is in a rest period and you do not know when it was last fertilized I think I would forgo fertilizer for now.

Please come back and let us know what you discover.

Hi Casey;

I have just a couple of things to add. Your tree is going thru an adjustment period, so don't be too concerned about the leaves. The tree does like a damp soil mass, so it's safe to water when the top ½ inch of soil is dry. If you let it get too dry it will drop leaves.

Additional light is a must for indoor bonsai. A 2 or 4 foot fluorescent fixture with cool white bulbs will do the trick. Place about 4-5 inches above the tree and leave on for 14-16 hours a day. A timer will help here.

As Gnome said, no fert. for at least a month. Any brand will work as the concept is the same. I've used Miracle Grow for house plants with good success. Dilute to ½ strength and apply every 2 weeks when plant is active. Once a month when tree is resting ( no noticeable growth). Water first, let drain, then water again with fert. mix. good luck and do get that additional lighting.
