How to fight plants with plants

I’m posting this article “How to Fight Plants with Plants”  by Nancy Lawson of humanegardener.com after mentioning it in class this morning.

Conoclinium coelestinum, blue mistflower, is a pretty native wildflower that can fill in areas to keep out other plants that you don’t want to colonize there.

Soil Quiz and Updates

Take this 10 question quiz before the second class:
Soil Health Quiz

Also: One of the biggest issues that homeowners are dealing with is compaction.
This is one of the things you are looking for as you observe your yard for your site assessment this week.
If you are unfamiliar with the topic of compaction, look under Soils in the banner above and select “Compaction.”
Your student manual also explains compaction starting on page 26. You’ll learn more about compaction and other soil issues when Alex Darr speaks on Thursday.

Bees, Bugs and Blooms–research from PennState

DSC01753

One of the things covered in this past week’s class was how to bring more pollinator-friendly plants into your garden. A few years back Penn State did a pollinator trial on which wildlflowers were most visited by pollinators and by insects in general. Here’s the link to Bees, Bugs, and Blooms where you can look at tables and figures.

Towards the top of most of their lists are the mountain mints (Pycnanthemum), goldenrods (Solidago), Joe Pye weeds (Eutrochium), and milkweeds (Asclepias). Above you see mountain mint, which as anyone who has planted it knows, literally buzzes with activity this time of year. Also above there’s Joe Pye weed and one of the perennial sunflowers, and a milkweed peeking out here and there. My goldenrods are not blooming yet, so not in the photo. I have a big yard which I allow to grow on the wilder side; you can also have a neater & tidier pollinator garden if you prefer.

I’ve put just the genus name above (in italics); you can look further at the lists to find out which ones performed best. If you’re just starting out with planting for pollinators, any natives in these genera (plural for genus) listed above is probably good.

Figure 1 shows phenology, or the time of year the plants bloom and are therefore useful to their pollinator visitors. It’s important to start to think about planting wildflowers that will bloom throughout the season, from April through October, or even longer, so that pollinators have food throughout the season.

Watermark Woods has most of these plants available, and is usually open Wednesday through Saturday mornings (check the link to be sure). Loudoun Wildlife’s Fall Native Plant Sale, where Watermark Woods and two other reputable vendors will have plants to sell, is coming up Sept. 9 and is held at Morven Park in Leesburg.  Staff and volunteers can help you pick out plants that suit your needs.

Another good resource for planting for pollinators: Using Native Plants To Attract Butterflies, Moths, Bees, and other Pollinators in the Washington, D.C. Area

Check back soon for more posts and links on topics we covered recently in class.

Fun with Soil

Jennifer sent these cool photos of her “jar test” of soil on her property:

Image-1        Image

She found that the one on the left came out as loam, and the  Untitled
one on the right as sandy loam on the soil texture triangle.
However, she was less sure of the one on the right as it was harder to read.
