ST. PAUL, Minn. (10/14/2013)—Drought conditions over the last two-plus years have left trees and other perennial plants visibly stressed this fall. Tree stress symptoms include abundant seed production, leaf scorch, early fall colors, leaf drop, limb dieback and yellowing or browning of leaves and needles.
Fortunately, several measures can help enhance tree and shrub health.
Trees and shrubs–especially conifers (such as pine, spruce and cedar) and those planted in the last three years–should be watered generously until the soil freezes. Mulching newly planted trees also helps reduce winter root damage.
Young maples and thin-barked trees may benefit from sunscald protection to prevent the bark from cracking this winter and spring. This usually involves plastic tubes or tree wraps, which are removed in spring. These practices can also help reduce winter animal damage. Other fall management practices which will help reduce winter damage to trees and shrubs can be found at http://z.umn.edu/winterdamage
Protecting trees from rabbits, mice, voles and deer is another major winter concern. Mow or remove tall grass to reduce mice and vole damage. If the bark is removed or severely damaged around the tree, it will die. Protective physical barriers such as tree tubes, hardware cloth or fencing can be done when practical.
Odor, taste and visual repellents can repel many wildlife species, but may have inconsistent effectiveness. Human hair, soaps, garlic oil, hot sauce and animal repellents can be applied to branches and foliage to discourage browsing. Weather, application frequency, animal population and feeding pressure affect the success of repellents. Alternate the repellents since some animals become desensitized to them. A web resource that reviews prevention and control of wildlife damage can be found at http://z.umn.edu/critters
If you’re unsure about what’s causing problems in your landscape, University of Minnesota Extension has a great website to help homeowners diagnose tree, shrub and plant problems or identifying a weed or insect. This site also has links to the University of Minnesota Plant Disease Clinic and Soil Testing Lab: http://z.umn.edu/diagnose
Fall is also a good time to plant trees; water them until the soil freezes. Recommended trees for all regions of Minnesota are at http://z.umn.edu/rectrees. The best time to prune trees is during the dormant season from January to March. Flowering shrubs can be pruned in the summer after flowering.

Soil Health/Cover Crops will be presented by Thomas Steger from USDA Natural Resources Conservation Service on Wednesday, September 11 at 7:00 P.M. in the Red Wing High School-Courtyard Cafe. The class will cover soil health including discussions on “soil critters”, recognizing healthy soil and the long-term ramifications of poor soil health. Tom will also discuss the use of cover crops, mulch and plant diversity and how they can benefit soil health. Soil glomalin effects on soil aggregation as well as soil stability and water infiltration will be demonstrated.
This class is sponsored by Goodhue County Extension Master Gardeners and Red Wing Community Education. The cost is $5. To register, call Red Wing Community Schools at 385-4565.
- Save soil structure by avoiding tilling
- Use recycled materials to create new humus or soil
- Reduce water use
- Provide nutrients for the polyculture of vegetation planted in the soil

Does your columnar arborvitae look like this photo as a result of the May 2 snowstorm?
Look closely to see if the stems are broken. Those need to be cut at the break or removed entirely. Arborvitae has some ability to re-sprout from broken stems, but only time will tell how a particular tree will respond. For stems that are bent but not broken, some will stand back up on their own. Others won’t do it on their own but can be supported with a splint for a few seasons until they regain strength. Use a long bamboo pole, wood dowel or flexible fiberglass pole. The latter are used for tents and for supporting netting in the garden. Strap the splint to the bent arborvitae stem at several points along the pole with Velcro tape or soft rags. Check the stems every few weeks throughout the summer and loosen the ties as the stem expands.
For other types of trees with broken limbs… If the tree has just one or two, it may be best to remove each broken branch entirely. Make the final cut just outside the branch collar. If there are many broken branches but the tree is otherwise safe to leave in the landscape, it’s best to cut off just the broken part of each branch. Use sharp tools but leave as much live tissue as possible on the broken stub. Healthy branches will re-sprout from dormant buds and it might be possible to do restorative pruning in future years. Plan to have a Certified Arborist work on the tree during the dormant season beginning in 2-3 years.
- There are 9 billion living organisms in just a tablespoon of soil.
- Keep soil covered with living plants or plant residues to avoid erosion.
- Minimize disturbance of the soil to limit weed seeds.
- Maximize diversity of plants in rotation, using plants from many different groupings such as flowers, herbs, vegetables, ground covers for visual interest and to limit disease that can spread in monocultures.
- Keep living roots in the soil to hold the soil in place as much as possible. Consider cover crops off-season.
TOO MUCH SNOW TO GARDEN? WATCH THESE VIDEOS :
Perfect timing! An upside of our new snow – it buys us time to get the word out. We have just a few weeks until garlic mustard goes to seed in Goodhue and surrounding counties. It is important for us as to take action with best practices in our own back yards and through education – watch the video to find out how.
Sorry about the first attempt to post this and the accompanying message that lead to nowhere – something glitched when trying to embed the first video, but as a result I found a second. Hence, just the links now. Your humble blogger, nlb
Few in southeastern Minnesota would deny that today is the first real day of spring of 2013. It is as if the earth danced vernal today. Blue skies and temperatures in the mid 40’s by 8am, my mission was clear. This morning I hiked up Barn Bluff with hopes of seeing the pasque flowers.
This being my third spring in Red Wing, the bluff did not disappoint. I enjoyed thousands of the furry little purple gems. Seeing the crocus on the prairie edge made me laugh out loud. Anemone patens var multifida or wild crocus is in the family Rannunculacea and is native to the US, Europe, Russia and Mongolia. It’s name “Pasque” comes from Old French for Easter in reference to the spring bloom – “patens” means spreading. it is a hearty soul, often blooming through the snow.
If you take the hike, get on your belly and enjoy their furry stems and leaves, velvet to the touch. In the morning light the petals shine like stained glass among the dry little blue stem grass (Schizachyrium scoparium.)
We don’t know how lucky we are to have the bluff top prairies right in our back yards. While less the 1% of native tall grass prairie remains, short grass prairies are a little more common (see http://www.npwrc.usgs.gov/resource/habitat/grlands/grasses.htm for more information on prairies.)
Thoreau and his companion Horace Mann delighted in the crocus on Barn Bluff when they visited Red Wing more than 150 years ago. They noted in their journal and letters home that “Pulsatilla still in bloom on top” on June 23, 1861.
It was an exciting hike up the bluff today. I thought I would see if the snow had melted on the north end (it hadn’t) and while there an avalanche of basket ball-sized rocks tumbled down the wall just 100 feet in front of me. With in a minute there were six turkey vultures circling – luckily the tumbling rocks missed me and they had nothing to discover!
