Happy Thanksgiving! Here are more images from some of our boutique meadow establishment projects going in the last few weeks. One is an Indiangrass mini-field down near Nellysford and the other is exclusive Black-eyed Susan dominated wildflower plot in Western Culpeper County. The image below shows plug layout after site prep. The second image shows what a fescue field looks like after 6 months of solarization (fescue kill without Roundup!) and then site prep. and then rolling of wildflower seed.
Regarding concerns about the human health effects of synthetic herbicides, what are other options? Well, in terms of a selective herbicide, there is only one we have used successfully – clove oil. Unfortunately the manufacturer went bankrupt we hear, and so that product is no longer available. So we are running trial of our own clove oil solutions. Another way to deal with this dilemma is to use desirable weeds to fight undesirable ones. This fall our first lawn projects are going in based on this principal, and include the use of combined carex/fescue as a form of shade tolerant lawn requiring a fraction of normal inputs. Here the carex, often considered a weed in the mid-Atlantic is the invasive weed fighter. The images below show the sedge plugs after just arriving at our office. The other image shows the plugs and fescue overseeed going into a new wood eco-lawn.
A few days ago we also completed our second microclover/fescue project – again the idea is to fight highly invasive weeds with friendly and attractive ones.
SoilKeepers advises clients to seek alternatives for synthetic herbicides whenever possible.
Growing grass under a 360 degree canopy isn’t easy in Central Virginia. You need a bacterial dominated ecosystem that our tree friends fight tooth and nail. You also need just the right amount of nitrogen. And then, to be able to sustain growth without synthetics, you need 5-7% Soil Organic Matter (SOM). In a tree soil ecosystem (fungal dominant) it can take 3-4 years to get the soil to where it can support fescue. Below we have another successful project – it took 3 years (6 seasons) – 100% organic protocol.
With Florence gone…we have vegetation responding – invasive vines of all kinds and those in turf, like Creeping Charlie, Virginia Buttonweed, are partying like its 1999. These weeds have deep roots in your yard and yes, you can go to your local Coop and buy synthetic chemicals, both selective and non-selective, and if you read university publications you will see that none work 100% of the time. This practically means: There is no end game with these these products, some of which are reportedly toxic to humans. We are trying other methods, that work with nature. It’s not foolproof but neither is the synthetic route. We are pioneering in Central Virginia the use of micro or mini clover with turf grasses to create aesthetically pleasing lawn vegetation. Clover is a weed most think today, but it used to be the go to plant for lawns. So, we’re sowing mixed clover and turf fescue in an effort to let one weed battle another. Micro or mini clover doesn’t flower like regular clover so concerns about bees are reduced – yet- as a legume they naturally fertilize your turf grasses.
Look, we get it that this won’t be for everyone nor is it the right choice for all settings, for instance, this is not a good option for heavily shaded areas. But for areas where the weed pressure is high, and synthetic herbicide use is not an option, this could help. And with the kind of root system on these weeds, like the evil Buttonweed below, we need all the ammo we can muster.
Staff completed Prescribed Burn Manager Certification Program with Virginia Department of Forestry. We will add fire to our tool chest for grassland management. The images below show earlier training in 2018 at Big Woods State Forest.
With Hurricane Florence on the way, our staff is tough, hard working, and does not mind getting dirty helping riverside clients with flood and stream cleanup and as always invasive species removal.
A few spring and early summer images from our yard and meadow (wildflowers and native warm season grasses) projects.

We have had 8 straight days of shallow soil temps. in the low 50 degree F range, so the season for cool season grass germination and growth is certainly upon us. Snow this weekend and several days of cool temps. will slow down growth but provide more needed soil moisture.
Folks, we are in a drought. Scan the Virginia Drought Monitoring Report for February. Increasing soil organic matter through compost/compost blend topdressing is the best way to fortify plant health to continued dry conditions. If the drought continues, it may be too dry to overseed this spring, but especially if your soil has low organic matter, at least topdressing with aeration will help what plants you do have survive the coming summer and will help fall plant roots to grow next winter. If you have low organic matter and you do nothing else, for your water supply and the supply of your neighbors, increase your soil organic matter through topdressing. And if you need help, call us – we’re the only Central Virginia Enterprise specializing in compost topdressing.
Question from client: How many times a year to aerate? Well, it depends.
SoilKeepers Manager Michael Collins spoke at the 23rd Ecological Landscape Alliance Conference in Amherst, Mass on Restoring Our Environmental Commons through Commercial Landscaping. ELA is a great group of folks focused on the practice of ecological landscaping. SoilKeepers has joined their efforts as a proud Member for 2017.
Also staff is now preparing plans for SK clients for this year.
The months fly by!
First, soil temperatures are heating up as are air temperature all over the country. This is a chart of Central Virginia soil information for Monday, February 20 (note the highlighted reading):
This roughly 10 degree C reading at 4″ below ground equals the weed growing temp. for crabgrass. Since it looks like the heat will continue for the rest of the week, now is the time to apply organic broadleaf weed control. Call us at 540-672-2542 to schedule an estimate.
Also, many of our older clients are now in their 3rd year of soil restoration and this year we’ll be switching them over to just liquid fertilization. This will dramatically lower costs because their soil after years of restoration is now healthy enough to provide most of the nitrogen the plants need.
