Plants that experience extremes in soil moisture may develop spots on their leaves, called “oedema” (also spelled “edema”). The spots may first appear as a blister or raised spot, particularly on the undersides of leaves, but may occur on the top side as well as on the stems. Eventually, the blister develops a rust-colored, cork-like[Read More…]

Hot, dry summers are not that unusual in the Midwest, but 2020’s hot dry spell started considerably earlier than usual, before summer even officially began! To make it a triple whammy, the hard freeze in early May caused some landscape plants to burn up more stored carbohydrate reserves to produce a second round of foliage.[Read More…]
Soil is the ‘lifeblood’ of plant health. Many people tend to focus more on above ground portions of the plant than the below ground environment. We should always remember that a plant is only as healthy as its roots. Knowing the basics of soils will help in understanding the health of landscape plants (Fig. 1).[Read More…]

As so many gardeners are staying at home these days, we’ve had more opportunity to enjoy the spring display. And then, perhaps inevitably, “normal” spring frost and freeze visited – some plants are vulnerable to damage. The amount of damage will depend on how far along they are in their development. Home fruit-growers may have[Read More…]
Most gardeners have heard of the wise advice “leaves of three, let it be” referring to the pest plant poison ivy. While not quite as catchy, the saying really should be “leaflets of three, let it be.” Poison ivy leaves are compound rather than simple – a single leaf is divided into three separate portions,[Read More…]
We often receive inquiries from folks wanting to add landscape plants that will attract birds. Most folks primarily think of plants with edible berries.

While we’re more used to seeing this happen during February warm spells, our frigid temperatures arrived a bit early in the[Read More…]
Deicing salts can save your neck this winter, but they can spell disaster for landscape plants.

Salts can adversely affect plants in several ways. Salts deposited on the[Read More…]
