We've had an Acer palmatum of some variety for around 45 years and for the first time this year did I notice a seedling after all that time. Where it's located at the moment it's very much in the wrong place, so, now that it's into senescence I guess I'll have to dig it up with as much of the surrounding soil as possible to avoid interfering with the roots and transfer it to a pot -2 gallon or up- which I'll dig in or whatever else is suggested. What are the odds of it surviving for any length of time? Other maple seedlings -not palmatum- I've had over the years have all been finicky and I'd be lucky to get them to around 5-6 years or so. Any advice is appreciated. Thanks!
