If you see small, uniformly shaped round spots that almost look like bb shots on leaves, it could be this critter:

4-Lined plant bug and damage.

This info is from our very own Jeff Hahn from the University of Minnesota:

• Yard & Garden Brief: 4-Lined Plant Bugs [U of M Extension]

When they’re small they are bright red. If you can get at them early, then pick them off and destroy! I personally favor squishing them. If it’s too late and you need chemical, then permethrin is an option.

Be sure to identify the bug properly, read the label so you know it will kill this specific bug and use exactly as directed. If you’re unsure, take pictures of the damage and who you think the culprit is and take them into your local nursery, look over the U of M diagnostics link or email me at .

Could be a fungal or bacterial disease.

If you see a random pattern of spots on the leaves of your plants you’ll want to check out the diagnostics link I have to the U of MN extension service. It’s on my Favorite Links page.

If the majority of the leaf is still green, not to worry. Remove the infected leaves, clean up the area and toss the debris. Do NOT compost it. Never remove more than one third of a plants leaves or you’ll do more harm than good. Air circulation is key to preventing fungal diseases. Mulch your plants to keep the humidity down as well.

Two new varieties of Echinacea are named for comfort food: ‘Tomato Soup’ and ‘Mac & Cheese’:

Echinacea Tomato Soup and Mac 'n Cheese

They grow to about 28-inches tall with a 24-inch spread once established. These are prairie plants and need full sun. They tolerate drought well. Unfortunately many of the newer Echinacea (aka Coneflower) are susceptible to Aster Yellows, a deadly disease. So, weigh the risk of losing them after a couple of years to the beauty you’ll get.
