It appears the desert of northern Hampshire County may get some precipitation from this storm afterall.

Cotton, Peanuts and Naked Ladies

Click here for interactive map
I gave a presentation in Suffolk, Virginia last Thursday, and found a short period of time to go scout the perimeter of the Great Dismal Swamp, one of the largest national wildlife refuges in the U.S.  On the way there, I saw fields of cotton, peanuts and soybeans.

I was surprised by the bare soil surrounding the cotton, which suggests high herbicide use.  I learned that cotton growers also employ an exfoliant toward the end of the growing season, and that enables easier collection of the cotton.

I learned a lot about peanuts too, and have been thinking about how they'd do in the alluvial flood plain soil along the South Branch that is an unusual mix of sandy clay.  Most sources say sand is good, clay is not.  That sounds like an experiment to me.

The Swamp

I had very little time to explore the Great Dismal Swamp, so I stopped in the refuge office, got a bird list, and the staff there uniformly recommended a short loop trial that visits multiple habitats typical of the swamp.

Bike trail in the Great Dismal Swamp
When I asked  how to spend a few days visiting the swamp when I had more time, they also agreed that a mountain bike in April/May is best.  With over 100 miles of interior hiking/biking trails and very comfortable lodging in Virginia Beach, the Outer banks of North Carolina, or at the Hilton Garden Inn Riverfront in Suffolk, that sounded like a plan.

Naked Ladies


When I returned to Hampshire County I saw Naked Ladies everywhere.  Their scientific name is  Amaryllis belladonna, and they're native to South Africa.  I have a few dozen thanks to my neighbor Puddy in the city, who regularly rewards me with neighborliness when thinning her garden.
Amarylis surround my farm equipment.

Naked ladies are also known as Belledonna lilies, and they have been popular with gardeners since the late 1700's because of their habit of producing leaves in fall or wet springs, then remaining dormant until now and suddenly sprouting a single stem with an attractive flower.  I like them because they are toxic to deer and groundhogs.

Experiments in Hibiscus Propagation

I've had lots of disappointments in propagating local and historically indigenous rose mallows (Hibiscus spp.)  They were the first plants in pre-colonial America to be cultivated for shipment back to Europe.  The seeds we've collected from locally growing Hibiscus moscheutos (white/cream-colored flowers the size of dinner plates) are always infested with mites that are not killed by freezing.

We ordered seeds of Hibiscus moscheutos, Hibiscus laevis (syn. militaris), and a subspecies of H. moscheutos often called H. paulstris (actually Hibiscus moscheutos palustris, Swamp Rose Mallow) from Prairie Moon Nursery.  We direct-sewed them naturally (as if they'd fallen from the plant's seed pod), and then spent many, many hours trying more advantageous seedings.  We've truly only been regularly successful when sewing the seeds in April in the greenhouse and then transplanting after germination (about 100x more work than our preferred approach!).

So now I'm convinced the only strategy for sewing seeds directly is to do so in situ after the last frost, in areas with appropriate moisture,  That's not easy, as that is our wettest time of year, and if you observe native H. moscheutos you'll see they grow immediately next to but not in the water.

That said, when the experiments are successful, the colors are impressive.     We fence anything (everything!) we transplant.  Hibiscus generally survive deer well, but as many of you know, deer usually don't know they don't like something without trying it at least once!

I don't know who this kid is, but I wanted to provide an example of the size of these flowers.

Growing Citrus in the Eastern Alleghenies

I'm curious to know what cycles others in Hampshire, Morgan, Mineral and Hardy Counties have witnessed in growing lemons, limes and other citrus.  The folks at Nature's Art in Cumberland (a very pleasant, easy place to spend money) started me growing lemons and limes last year.  Most start producing fruit in April and May indoors.  We move them outside after mid-May (about 10-14 days after the predicted last frost).  Yesterday one of the limes produced a new flower, even with nearly mature limes already present.

Rain barrels and rain chains

After the rains over the last 10 days, I'm convinced that rain chains simply won't work with typical rain barrel setups.  The rain chains are aesthetically pleasing, and they disperse the water in a way that doesn't cause erosion, but the water is broadcast too widely, even if your rain barrel is topped and surround with plants all around.

While it's easy to drain the water on top, it's difficult to screen that water, which is typically filled with small leaves and other things that will clog spigots, valves and our sprinkler and soaker hoses.

Spiny Softshells of the Ohio River Watershed


Our Hampshire County watersheds mostly drain into the larger South Branch, Cacapon, or Opequon  watersheds, or directly into the Potomac.  During my adventures with the West Virginia Youth Science Camp in the Kanawah/Ohio watersheds, we saw a few things that surprised me, but the juvenile Eastern Spiny Softshell turtles (Apalone spinifera) were the biggest surprise.

While geocaching on July 12, Stephanie and Rachel found this softshell below one of the Cedar Lakes dam's spillway after a rain.  I worried that it would be in danger as the grass dried in the 35oC temperature (and as the grounds crew began mowing), so Rachel placed it back in an aquatic environment.

On July 15 we found an even smaller softshell in the recently mowed grass heading uphill and across the road to one of the lakes.  I made the decision to accelerate it's journey because of the roadway.  The lake had a few very large snapping turtles - we noticed a few geese with missing feet and broken legs - but the lake certainly seemed safer for an aquatic turtle than a road.

During college I worked with Florida Soft-shelled Turtles at ZooAmerica, and apparently the Eastern Spiny Softshell is just as fast, and similarly aggressive as a hunter.  Its shell is smooth except for the small spines on the front of it's shell that give it's name.  The spots also seem to distinguish it from the smooth softshell also found in parts of the Ohio river watershed.
 It is primarily a river turtle, and it likes to bury itself in the sand or sandy gravel or mud of river bottoms with only it's snout visible (see photos below).

Most interesting to me is that it can get oxygen from the water. Its embryonic pharyngeal gill slits (which all vertebrates have) become a highly vascular pharynx with a lining thin enough to remove oxygen from the water.  I haven't found a diagram or image of this yet.  If you find one, add a link in the comments below.

Like other aquatic turtles, it buries its eggs on river banks exposed to the sun; but unlike other turtles, the egg development is not temperature dependent.
