| I Posted this on the Tree forum and was suggested I post here.I have 2 Japanese maples Both are several years old. One is large and green with red tips. The other is a red lace leaf weeping variety. The red tree suddenly has a branch sprouting from the main trunk that is from the green tree. I am just curious as to how this happens naturally? I was told to prune it off as it may overtake the red tree.

| I'm not an expert, but since no one else has answered, I'll give you my best guess since I have had some experience with them. Most weeping JM's are grafted onto another JM root stock. It's possible the original base has sprouted. Look at the base of the trunk and see if there is a knot where the weeping part was grafted. If the green shoot is from that area, that's likely what happened. It should be pruned out because it could cause problems for the tree. Beautiful JM's BTW. |

| Both the rootstock and the nearby free-standing specimen are wild-type green Japanese maples and that is why they look similar. They are not a single individual that has somehow gotten under the weeping red laceleaf maple. |

| The green shoot is growing from the root stock onto which the red leafed type has been grafted. It is quite common with all sorts of shrubs. It can be seen alot in roses. Im currently working on a Japanese garden that has been left wild for a few years and we found a huge maple that this had happened to. Since the red tree we have is of a vertical habbit the root stock has grown higher up and I only discovered that it was one tree when I clambered in behind it to cut back some bamboo. There is no real risk to your tree except that root stock plants are choosen for their vigour. This being the case it means that shoots from root stock can quickly overshadow and out compete the graft. The red leafed graft will also not photosynthesise as well as the green leafed root stock so your original plant will grom more slowly than the new shoot. Just nip it out as close as possible to the mainstem. |
