All Test Plots - Pictures of properly prepared Pollinator Zones (Initial Steps for Site Preparation)
Test Plot 1 - Smothering with black plastic, leaving in place for 4 weeks, removing for 2 weeks. Planting late fall with seed mix
Comments: This is the standard organic approach to planting a small space from seed. It is very low cost and works well. By taking the plastic off several times during the summer, it gives any remaining weed seeds a chance to germinate and then to be killed once the plastic goes back on. This and test plot #5 are very similar. For a full description, feel free to watch the PZ101 Webinar from this last June on our websiteTest Plot 2 - Removal of sod manually or with a sod cutter; Planting with larger potted plants
Comments: We did this one to show you what to expect if you decide to clear the area of preexisting turf grass. This is hard work but if you have some experience and a strong back, it can work. However, there will be weeds no matter what you do. But, using potted natives (available at more and more nurseries these days) you can minimize weeds with mulch between plants and some diligence. This approach is expensive, but you get pretty much immediate results. Plan to spend $10 or so per pot. This plot has a total of 25 plants in the 10X10 area)Test Plot 3 - Solarization using clear plastic for a full growing season. Planted the following Spring with seed mix (Spring 2021)
Comments: This variation uses clear plastic and it is left on for the entire summer. This is another inexpensive method that does not disturb the soil which is a good thing, and pretty much burns everything up during the hot summer months. You can either plant in late Fall or the following Spring based on your preference. This test plot will be Spring planted using the same mixTest Plot 4 - Repeated tillage of site every 3 weeks for a full growing season. Planted with plugs 8 weeks before freeze
Comments: This test was done to show what rototilling would produce and then planting the plot with a plug kit from one of the seed vendors. This test plot was first sprayed with glyphosate (once) and then tilled every few weeks. You could also just spray two or three times rather than till. Native plugs are certainly more expensive than a package of seeds, but they should do well and are more cost effective than the larger plants used in plot #2 above. The photograph shows 25 plants in this area. Over time, those will spread and will likely need to be split and transplanted as some of these plants get quite large. Tilling in general while effective and controlling weeds, is highly disruptive to the soil and to the organisms that live in the soil, but we wanted to show it as it will work and many people till their gardens.
