Invasive Plant Removal

    Date Posted: Thu, Jul 18 - 2:00 am

    Question

  • Are there any volunteer groups or does Richmond City help get rid of Japanese Knotwood, Chinese privet and tree of Heaven. There is a lot of all three on the property adjoining mine.
  • Answer

  • This is a great question! Removing invasive plants around the city is increasingly becoming a priority for many and its great to see! So many Richmond neighbors are helping to decrease invasives and bring more natives back to our area. The primary group that I am aware of that is currently tackling this work is the Invasive Plant Task Force that is connected with the James River Parks Systems. Their website is: https://jrpsinvasiveplants.org/ If the property you are concerned about is near the river they may be able to help. And they may also have other connections and contacts that they could provide to you. Thanks for reaching out - good luck! This is hard but good work!

invasives

    Question

  • 1) I have rampant overgrowth of wisteria, as well as more limited poison oak in an area covered by pine straw, ornamentals on perimeter of area, but worst parts are distant from these bushes. 2) Also widespread seeding from a mimosa (since cut down, but too late) throughout the front lawn. I'm averse to using Round-Up, and wonder if you can offer solutions and guidance. Many thanks! Catherine Davis

  • Hello there, There's a lot do here. The wisteria should probably be dug up and put in the trash. They are rampant vines. I have seen some people do an excellent job of training them and keeping them in bounds. It all depends on your maintenance tolerance. If they are left to run wild they will climb trees and kill them over time. The poison oak (which I think is actually native but no one actually wants it in their yard) should probably be smothered. I understand you not wanting to using Round-up or a similar product, I wouldn't use it either. If they are young and small plants depriving them of sunlight, water and nutrients will over time kill them off. It could take several months but doing it now with this hot weather will help the soil heat up to kill the plants. Tarps, cardboard, plastic sheeting, these should all work. This process works best in sunny sites, you didn't mention the exposure. I've also had success using straight white vinegar on any plants that survive and re-sprout. And of course, be sure to wear protective clothing, head to foot, any time you are working with poison oak or ivy and put the clothes in your waster with hot water when you're done. As far as the mimosa seedlings, I can only imagine hand pulling them. I don't know the area in question but using vinegar in your lawn will damage the grass and I'm sure you don't want that. Hand pulling is one of the most effective methods to use when possible because you can often get the root of the plant out. Having a good thick ground cover is the best bet for keeping out all those unwanted plants. If there's a vacancy, they'll occupy it!! Best of luck Catherine!!

Raised beds, native ground cover, bio-diversity, dog-friendly

    Question

  • Thank you for doing this, first of all! My question is: How do I maintain a yard with raised garden beds, while also allowing natural biodiversity to thrive AND keeping it safe for my 2 small pet dogs to roam in? I am about to move into a place with a beautiful, old mulberry tree and a yard full of both native groundcover and some invasives like English ivy. I want to convert it into a big produce garden to share with my neighbors, and have planned out having 4 raised beds, along with allowing native groundcover to grow between the beds. However, I also want to be mindful of the fact that I need to keep any plants that may harm my dogs away, and keep ticks to a minimum (though I know theyre kinda unavoidable because nature is nature). Whatre your thoughts/suggestions?

  • It sounds like you've got a great plan. Assuming you have the right amount of direct sun, 6 hours or more, you should have a good site for growing vegetables, herbs ,etc. You mention a large mulberry tree, I hope that it doesn't prevent you from getting the right amount of sunshine. Are you planning on building frames for the beds? I find this to be the best method. It helps deter critters (domestic and otherwise), allows for good drainage, and helps keep weeds at bay. Since you already have some native ground cover you could make the most of that by dividing the existing planting and planting the divisions between the beds. I'm not sure what native you have but if it can take some foot traffic that would be the way to go. Dividing is most successful when done in spring or fall. It sounds like you've got a good amount of yard space In addition to the raised beds so for diversity you could add native shrubs and perennials. Blueberries make an excellent edible addition to a shrub planting or border. There are many lovely native shrubs to choose from - summersweet (clethra alnifolia), fothergilla, sweetspire (itea viriginica) - to name a few. Just remember - right place, right plant. Be sure to consider the specific location you are planting in: sunny/shady, moist/ dry, etc. As far as dog-friendly plants go, I would make a list of all the plants -food and ornamental- you're considering and then check the web to see if any pose a danger to dogs. For example, some herbs are a problem for dogs and some are beneficial, so it takes some research. Regarding maintenance, the raised beds will help with this for the vegetables and herbs, and generally, all plantings (shrubs, perennials) are easier to maintain when a good mulch is applied right after planting. Also, close plantings can minimize space for weeds to take over and a mature ground cover pretty much takes care of itself. And lastly, a convenient water source is critical. I think you'll have some fun with this-Good luck!
