Keep trees green, gardens growing ... and deer out
By Terry Yockey
When you have a lawn or garden question and call the University of Minnesota Extension Office or leave a message on the Goodhue County Extension Master Gardener voicemail line at 651-385-3096, Robert Jacobus is the Master Gardener that calls you back with an answer.
Robert answers more than 250 gardening questions every season and says that so far this spring the majority of questions concern tree problems. He explains that many of the trees in our area are showing the delayed effects of stress caused by the high temps and very dry autumn of last season.
"Trees need to be watered deeply going into winter especially when there isn't enough precipitation."
Robert recently completed the six-week Tree Care Advisor course and says, "I learned a lot of about trees that I didn't know before, especially how many things I accepted as fact that I found weren't true at all."
For example, most people think that the rule of thumb for watering a plant -- whether it is a tree, corn or lawn turf -- is one inch of water per week. The real fact is that for all plants, and especially trees, the amount of water a plant needs depends on many different variables and there is no "one size fits all" when it comes to watering.
The Jacobus yard and gardens
Robert and Mary Jacobus moved to Red Wing five years ago and brought many of the plants from their previous home in Iowa with them. They immediately began planting gardens, trees and shrubs on their new lot and quickly found that the deer were not going to be congenial neighbors. The deer ate pretty much everything and also damaged the bark of the young trees where they rubbed their antlers.
For three years Robert tried to find plants the deer didn't like and products that would keep them from harming the trees and shrubs. He had some success, but last season he finally decided enough was enough.
Robert spent three months designing a new 6-foot high, deer-proof fence that would not only keep the deer out, but would also be esthetically pleasing.
His new fence is made of rough cut western cedar and PVC coated wire. He chose black coated wire for between the 4-by-4-inch and 6-by-6-inch posts, because the color blends into the garden behind making the wire appear almost invisible.
Inside the fence
Robert grows a variety of annual and perennial flowers inside the new fencing.
Each year he starts over a hundred plants by seed and cuttings under lights in his basement. Some of his favorites are celosia, zinnias, Swedish ivy and many different varieties of marigolds.
Clematis is also a new favorite and 12 vines grow on trellises spaced around the inside and outside of the fence.
Vegetables also share the fenced area with the flowers and other protected plants. Cucumbers, tomatoes and onions hide behind the bright annuals, but are easily harvested from the pathways that meander through the gardens.
Unique container plantings
Each year Robert plants over 30 unique planters with a variety of colorful annuals.
Although by her own admission his wife, Mary, does not take an active part in most of the garden projects, she does enjoy the many seasonal visits to local garden centers as they collect plants for the containers that decorate their porch, patio and many other places around the house and gardens.
Distinctive new annual varieties are always brilliant spots of color in the container plantings, but Robert also uses many tubers year to year including calla lilies, caladiums, begonias and cannas.
Protecting the other plants
Now that Robert has most of his flowers and vegetables protected behind the deer-proof fencing, he is on a mission to protect everything else in the yard that suffers from deer browsing. -His newest defense is a low-voltage electric fence around the hosta bed next to the patio. Most homeowners are reluctant to install an electric fence, but the low-voltage wires give off just enough zap to keep the deer away and only give a slight sting to a stray human that might accidentally touch the wire.
One caveat: You do have to get a permit from the city of Red Wing if you decide to use any electric fencing within city limits.
