What's under and/or around your Japanese Maple? Pictures please!
Comments (23)Why anyone felt it was necessary to resurrect and add on to an inactive 12 year old thread is a bit strange........but let me just add this comment. Japanese maples produce shallow and extremely sensitive root systems that resent any sort of disturbance. In fact, it is extremely easy to introduce often fatal disease issues by damaging these roots. So whatever one chooses to underplant their JMs with, it should be something that can be left undisturbed and with non-invasive roots. No annuals that require yearly replacement or perennials that will need frequent division. Smaller, non-suckering shrubs are fine but should be planted simultaneous to the maple. Or any low growing, shallow rooted groundcover....See MoreNon-Invasive Butterfly Bush ?
Comments (34)Update: My Buddleia davidii has since been shovel pruned. I kept getting severe ifestations of Two Spotted Spider Mites. I tried to control them with a jet of water, but that didn't work. I tried to control them with foliar insecticide, but that didn't work either. The second year was more of the same, but the spider mites began to spread to other plants in my yard. That was when I shovel pruned the butterfly bushes. The spider mites are gone from my yard now and I'm still not sure why the Buddleia davidii in my yard had such a problem....See MoreMass seeks comments on invasives ban
Comments (45)I'm a first time poster on this forum. What an extremely interesting thread!! I have to agree with Ellen and others. Norway Maple is extremely invasive, highly prolific and it doesn't just shade out native plants, it leafs out earlier than many natives, thus not even allowing them a chance. Burning bushes may be used as foundation plantings, but anything that berries easily becomes invasive (e.g. Asiatic bittersweet). Notice where bittersweet grows? Under trees and power lines where birds sit and defecate the seeds! What a great evolutionary trait that they picked up. No wonder there is so much of it in our woods! Burning bush berries are loved by many birds. As you are driving along someday note a BB denuded of leaves. You will notice it quivering with birds (usually non-native house sparrows). You may not notice all alien invasives, but I see plenty of volunteer burning bushes around on road edges and wood edges. If you really start to look for these things, you'll see how bad the situation is. I had read somewhere that poison ivy was brought here as an ornamental in the 1700's. I have a hard time believing that though. You'd think the person that dug it up would have realized its "down" side. Personally, I think a ban is a great idea. It would make some of the housing developers and nurserymen use a little more imagination in choosing foundation plantings and things to sell/plant. How many more Norway maples and burning bushes do we need? At this rate, everyone has one in front of their house or at least 10 in their neighborhood. The other issue is that while you may be right that we can't reverse what is already done, I agree that making it a law is highly educational. The nurseries aren't going to educate people. I, personally, did not know about this issue until after I bought some nasty invasive plants. I have never understood why our government continues to allow known invasives to be sold. They spend millions trying to eradicate some invasive alien weeds. The fact that we can't solve the entire problem is no reason not to attempt to prevent it from getting worse. There are plenty of really nice alternatives to most of the invasives on the list. Anyone that lives in Mass. can go to New England Wildflower Society and see the lovely gardens that they have created with natives as well as buy some really nice, healthy native plants. AND your gardens will probably look quite different from most of the neighbors....which in my mind is a plus. Just my two (twenty?) cents.

Comments (13)Terrene - A bit off topic, but if you can find a local woodturning group, you could try contacting them to see if anyone is interested in your 3 foot diameter Acer platanoides. Norway maple is a nice wood, so you'll be getting rid of an invasive species and having it turned into something beautiful. I'm an amateur turner and have lots of buckthorn. In rooting it out I noticed the pretty orange color just under the bark and decided to try turning it. I've used it for Christmas ornaments which are small enough to use the small diameter wood I have. Makes me feel like all the time I spend removing buckthorn isn't such a total waste since some of it I can use. In addition to the buckthorn (lots and lots and lots!) I have some bittersweet, a couple of kinds of honeysuckle (vine and shrub), pruple loosestrife along the river, and some barberry. I have enough property that I'll never get rid of it all, but on an ongoing basis I work to reduce what invasives are there by pulling, cutting, and judicious use of Roundup. I'm pretty careful what I plant since I'm in a rural area and invasives can really spread into the woods. For instance, I've been waiting to see about Heptacodium. It seems like a great plant, but it's a relatively newly marketed one, and although I've heard nothing about it seeding around, I decided I'd wait to be sure that it wouldn't develop that problem. An example is that only now are the pears (like the Bradford and Cleveland) being seen as invasive in the southeast, long after they have been planted in every other subdivision. Perhaps I'm being overly cautious, but I see what problems are created when plants attract animals that help them seed themselves around, and so I really try to avoid the problem. I get information on invasives here on GW as well as other internet sources and books. I also look around at old fields and other sites where invasives often move in and make sure that I can ID most of the plants there as a way to familiarize myself with pioneer species, some of which are fine or native, but others are foreign invasives. I usually consult several sources before I get a plant I'm not familiar with, and if it either runs through underground roots or is a prolific seeder, I don't buy it. It's way too much trouble to remove a plant I end up regretting (the voice of bitter experience) than to avoid it in the first place, no matter how attractive it may seem....See Moretsugajunkie z5 SE WI ♱
