Hello All,
I own a landscape business. We practice organic/natural landscaping whenever possible, but of course all nursery plants aren't free of synthetic chemicals. We do what we can. That said, I'm looking for techniques to kill invasives and replace them with natives and pollinators.
Aside from manually removing invasives, mowing, solarizing and monthly maintenance to remove persistent invasives, I'm hoping to utilize a non-selective organic herbicide to spot spray. I will need to amend soil as well, so, I may consider tilling after invasive removal. This will likely bring additional seeds to the surface that will germinate, so ill need to re-solarize or spray these plants.
The following is my tentative plan. I'm sure this will change on each site and as I learn. I'm open to suggestions. Thank you in advance.
Side Note: USDA Hardiness Zone 6a-7b
Identify natives that I'll keep and flag them.
Manually remove non-native/ invasive plants. For example hostas and english ivy. I know these are persistent and I will have to go through them several times to kill them.
Brush cut/ scalp areas after invasives have been removed/ dug.
(potentially spray at this point with an organic non-selective herbicide since plants are vulnerable after scalping.) Anyone heard of EcoMight? Its new to me, and looks like good marketing without third party results, but who knows, it might be worth checking out. If anyone has experience with this product, I'd love to hear about it.
4. Solarize the areas that are to be replanted with natives. (I'm thinking silage tarps/film since the leach minimal petrochemicals.)
5. Remove solarization tarps, let persistent plants come back. Spray them with a non-selective organic herbicide and solarize again. (Potentially till at this time)
6. Remove tarps, amend/ work topsoil and plant with native seed mixes. (spring and/or fall planting)
7.Maintain plantings to remove weeds until natives are established. Then, continue with a monthly maintenance schedule to remove non-natives.
***8. Actual beds will be treated differently than large scale over-seeding. Landscape/planting beds will be mulched with cardboard, inoculated with endemic fungi and mulched with hardwood or pine to mitigate weeds while native plants are becoming established.
Does anyone have experience with any of this large scale native seed planting?
Does anyone have experience with commercial non-selective organic herbicides? If so, any recommendations?
Any advice is appreciated.
