What’s wrong with my ‘Annabelle’ hydrangea?

Last year around this time (late April or early May) I noticed something strange about the leaves on shoots of my old, reliable ‘Annabelle’ hydrangeas. They looked glued together into a puffy, leaf-shaped balloon. What was wrong? In fact, they were “glued” or rather tightly stitched together at the edges. Turns out the culprit was the larva of […]

My bargain Clivia might have a virus

When I find one purported to be Helenproof, I’m on it like bees (or Battersbys) on honey. How thrilled I was to hear about Clivia, an easy-to-care-for flowering bulb […]

Poison Ivy: Better not touch

Poison Ivy (Toxicodendron radicans) – “leaves of three, let it be.” Hiking with Mr. TG last weekend, it became clear that my former- Scoutmaster husband had forgotten what poison ivy (Toxicodendron radicans) looks like.
