ginkgo biloba 3 year old seedling help
« on: November 30, 2014, 04:46 PM »
I'm am brand new to bonsai, so forgive me if this is a very novice question.

I got a 3 year old ginkgo biloba seedling through the mail from Alabama, and I'm in Colorado.

I'm un USDA zone 5, borderline 4b.  All of the non-bonsai websites say this is a hardy species down to USDA zone 4.

Many of the bonsai websites say to protect the from freezing, so I'm confused.

Colorado has frequent periods of warm weather during the winter (many days above 40 for high), but we also have severe cold weather, so I'm concerned about this little guy being from Alabama.

I'm thinking about leaving him out until weather gets nasty, and place him in the garage when weather gets below 20, and place the pot a hole in the backyard when weather is nice, or I can place him in a covered window well and water him throughout the winter.

Besides getting him through the winter, I'm thinking long term:
2016: plant in bonsai pot
2017/2018: work with local experts to start training and pruning

Thoughts?

Hey,
I live in Boulder and what you will find is more challenging with your plant will be the spring time here. As for winter, since your plant has dropped its leave, it requires no sun at all. That coupled with the best thing being consistent winter temps for plants, just put it in your unseated garage and try not to forget about it as it will need some moisture throughout the winter. However, be careful with the soil that you have it in as it appears to be very water retentive. It should not stay soaking wet, but not fry out completely either. As I alluded to earlier, when buds start to open up next spring is when you will need to move it inside and outside depending on temps.

Lastly, the first work you should preform next year is to get it in some modern substrate.

Rocky Mountain Bonsai Society would be a good resource if you are in the Denver area.

Oh, where was it a few weeks ago when Front Range temps dropped to -15 degrees?

I've a few and I've never fussed with them w/ freezes.  I suspect your plan will be fine.  I wouldn't bother with the hole, but it won't hurt either.

It was still in Alabama during those cold temps.

Patrik, I'll ask my local Bonsai seller if he has some different soil.  (Colorado Springs area has only one)

I've been doing some research tonight, also, I noticed there are different cultivars of ginkgos, so, now I'm concerned which variety I have...

Can any variety of ginkgo be dwarfed?

It needs cold temps for dormancy but I suggest you don't let it freeze, keep it between 34 and 38 if possible. Or if your garage gets below freezing put it in mulch in a large pot or cooler (with lid open). (I say this because it came from the south). Also gingko has fleshy roots.

2016 in bonsai pot - it will still be a stick, gingko is very slow, it is years away. Variety - it is probably the species since there is no graft (as far as I can see).

Can it be dwarfed?  - leaves cannot be reduced much. However gingko makes a nice bonsai with a thick trunk and it is easy to grow.

Best regards,
