In the Land of 10,000 Lakes, water is seemingly plentiful, but an abundance is still no excuse for negligent water use, whether it’s indoor or outdoor. Each year, the Irrigation Association promotes July as Smart Irrigation Month, but what does it mean to utilize "smart irrigation"? 

Dr. Dan Sandor of the U of MN Turf team explains the importance of utilizing irrigation only as needed, and how to use technology and research data to help guide your decision about when and how much to water.

Last week, the Minnesota Department of Agriculture (MDA) announced finding emerald ash borer (EAB) in the southwest corner of Minnesota in Nobles County. Infested trees were found in the city of Worthington right off of Interstate 90, which indicates that EAB was transported by people to that site. On its own, EAB can only fly about 1 – 2 miles a year.

This is the 19th county in Minnesota known to be infested with EAB. This invasive beetle was first found in Minnesota in 2009. Since EAB was first found in North American in 2002, it has killed hundreds of millions of ash trees and has cost hundreds of millions of dollars.


Minnesotans can help prevent the spread of EAB with these three easy steps:
Don’t transport firewood. Buy firewood locally from approved vendors, and burn it where you buy it; Be aware of the quarantine restrictions. If you live in a quarantined county, be aware of the restrictions on movement of products such as ash trees, wood chips, and firewood; and, Watch …

The gardener's mantra "Right plant, right place, and right purpose" may be filled with assimilation, but it actually hits nail on the head. For a successful, healthy yard and garden, you've got to choose the right plant for the right location and purpose.

For example, you should avoid plants with thorns in play areas or along narrow paths. Plants that grow tall should not be planted on the south side (sunny) of shorter plants as the taller plants will block the light. Plants with woody trunks and stems shouldn't be planted where you routinely pile up snow as the weight can break branches. You get the picture.

I taught a lot of plant selection classes this year - 8 sessions in total - and found myself explaining plant selection over and over. It's clearly easier to show people, but often my classes are taught in the winter - not very conducive to selecting and planting.

Did you know UMN Extension is part of a National Rose Trial and has been since 2015?  The trial is part of the American Rose Trials for Sustainability® (A.R.T.S. ®) program that has trial sites across the United States.

Since 2012, the goal of A.R.T.S. ® is to identify roses that perform well in a given region when grown under "minimal input conditions." So what does that mean for gardeners?

The program identifies roses that survive without pesticides, fertilizer--and aren't even covered in the winter! Read on...
How does the trial work? Clay County Extension Educator Randy Nelson has been managing and overseeing the trial since 2015, which is located in Dilworth, MN. Clay County is mostly Zone 4a (-30F to -25F); just a bit of the western edge of the county is Zone 3b (-35F to -30F).

Each year starts a new trial with 20 cultivars (three of each kind are planted). The trial is run for two years (evaluations start the year of planting and finish the following year so rose…

This native grass with its funny golden sails at the tip of its stems is known by many common names--"eyelash grass," "mosquito grass" (because it looks like mosquito larva), "caterpillar grass," and also, blue grama (Bouteloua gracilis). 
Why plant it This under used native grass is a short tough perennial. It is drought tolerant and can grow with very little rainfall or supplemental water. It also provides food for more than a dozen butterflies species as well as wildlife. More on that a little later on!

Native to most states in the U.S., blue grama is found in most counties in the central and western United States. Blue grama is the state grass of Colorado and New Mexico and is an endangered species in Illinois. In Minnesota, it is common in western counties and found in most upland prairies.
Growing requirements Blue grama is a predominant grass of the short and mixed grass prairies. It thrives on dry sites and once established it will live and self …

Is it the middle of summer as you read this? Common milkweed (Asclepias syriaca), is a Minnesota native wildflower that blooms in midsummer. Its lovely fragrance often proceeds your seeing the flowers. This is the milkweed that supports the monarch butterfly and is very valuable to include and maintain in our landscapes today.
Essential for the Monarch butterfly life cycle Monarch caterpillars feed exclusively on the leaves and the adult butterflies need milkweed to lay their eggs. They also feed on the nectar of the flowers, along with other flower species. Milkweeds have complex flowers; when you examine the individual flowers that make up the pink flower balls you will be amazed at their form and detail.
Growing milkweed in your garden This native plant is aggressive and can be weedy. The famous fluffy seeds float everywhere in the fall when the pods split open. The plants also have underground rhizomes that colonize to make a large stand of many plants.

Common milkweed loves full…
