Herbicide Damage to Vegetable Plants

Twisting, curling, and cupping of leaves are often symptomatic of herbicide damage on vegetable plants.

These herbicides are plant growth regulators, killing weeds…

Oakleaf

Hydrangea quercifolia or Oakleaf Hydrangea is a small deciduous shrub reaching about 6′ tall about the same if not more in spread.  Growing in full sun to full shade this North America native shrub is a consistent bloomer and easy to care for.  What I find appealing to about this plant is the lack of…

Maple Bladder Galls—“Freckles” on the Leaves

If you have a sliver or red maple tree, you’ve most likely noticed small raised bumps on the leaves.  Tree owners will call them “freckles”, “measles” and sometimes even “zits”.  Whatever they are called, maple bladder galls are caused by a very tiny mite.  The galls themselves are made up of plant tissue and are…

Itoh Peony

Peonies are one of the longest lived perennials that you can plant for your home landscape.  Anecdotal evidence suggest that they can live for 3/4 of a century if not longer.  Currently there are about 33 recognized species of peonies with only one maybe two native to North America.  Most know only the herbaceous garden…
