was poetic about boxelder????
Comments (30)The tree is healthy. It is certainly protected because it is over 3 inches in diameter at 5 feet. Anybody trying to fell it would have a fight on their hands. It's not mine to remove the paving from. When it raises the stones I dare say they will be altered by someone. Heaven knows where the roots go because, as you can see, it is bounded by a light well to a basement on one side and behind the mossy wall the ground falls away and there is a downward sloping path. So it can only really root in two directions. These are the rules: Trees with a diameter in excess of 7.5cm (3 inches) measured 1.5 metres (5 feet) above ground level are protected by law, and 6 weeksâ written notice must be given before any tree work, not just felling, is undertaken. For trees being felled to aid the growth of others (i.e. thinning operations), the threshold diameter is10cm (4 inches). Anybody hazard a guess at its age? I have no idea....See MoreWhats wrong with my maples color
Comments (8)PoorOwner- Pleaching is distinctly from the center and is bleaching or bronzing of the leaf. Often it starts near the base and center of the leaf. This is the plants response to more direct sun than it cares to handle. The integrity of the leaf is still intact and no burning or scorching has occurred from the most part. With leaf tip burn, it is normally a result of too little moisture or hot winds. If the plant cannot provide adequte mositure to meet the loss, then you see this. Likewise, if the conditions far exceed what the plant can handle, then you will see margin burn or scorching which compromises the entrie leaf. The leaf will be crispy. When the entire leaf is scorched it may fall off and be replaced or if not damaged enough, it may stay as a sad reminder of what has happend. My Fireglow is beginning to pleach or bronze at the leaf base now, but I do not have any crispy areas. Fireglow will not handle the full hot sun and it will scorch and burn. It will put out another set of leaves if they drop, and sometime even a 3rd, but if the tree pushes too late in the year to set buds for next spring due to the damage it has encountered, then you risk losing the tree or branches on it.

Comments (4)I doubt it would work as they are in different sections of the genus Acer, you can generally only graft maples within the same section. Apart from the subspecies of Acer negundo there are no American species in the section Negundo. Not practical experience of course, but hope that helps anyway........See MoreGrafting/budding on Acer grandidentatum
Comments (3)Actually, my question wasn't very clear. Acer grandidentatum can handle a pH between 6.0-8.0 and remain attractive. Its fall color is brilliant. Out here we see hues between yellow to orange to red to maroon - even on the same tree. But, it is not what I would call ornamental because it is large. We can plant ornamental trees out here. But, they struggle and lose a lot aesthetically. Maybe they are chlorotic or because they are weak, bugs or disease attack them. The Bigtooth Maple (A. grandidentatum) is attractive. But, it is big. It's not what I would call an ornamental tree. I save the term for something smaller with habits such as weaping; or flowers. These are the kinds of attributes I hope to use as scion wood. I thought that the Bigtooth, or even Boxelder (A. negundo) would provide a good rootstock to handle the pH situation while grafting on something ornamental. That is hoping that the scion will not effect the pH tolerance of the rootstock. Also, like Ron48 alluded to, most grafts/buds will only take within its own species. So, that leaves the list you provided me. All of these are thought to be within the Sugar Maple species (A. saccharum). But, they are all large, less ornamental. I found online a successful graft with the Arizona Walnut (Juglans major). This crosses the genus barrier. Also, many apple (Malus sp.) orchards graft onto a quince rootstock. Again, a different genus. So, these give me hope. I'm going to look more into the list you provided. Thank you. But, it looks like my best hope here would be a cultivar. At school (I'm a student at Utah State), we have a small orchard of Bigtooth that is being used as a research project trying to select various cultivars. We have a few that have selected autumn colors like only yellow, or only maroon. These are great. I think I need to wait on a mutation that dwarfs one, or contorts one. These we could propagate vegetatively. As far as tapping for sugar, I don't care about that. Hey Ron, thanks for your thoughts. If you have anymore, please share. I am still learning. But, I'm learning about something that excites me. eric...See Morelucky_p
