Your questions: tree talk

Readers have trees on their minds this month.

Dale, who lives in southeastern Wisconsin, submitted the following question: I have a beautiful Walnut tree but it has been sprouting branches near its
bottom and just does not look right.  Can I prune them now ? If so what angle? And should I put something on the exposed ends? Some of the branches are approx. an inch in diameter. I surely don’t want to harm my tree!

Teresa submitted the following: I am in need of help to get rid of the seedlings from my pear tree. I need to know when and how to manage them as I have a flowerbed under my tree. I did not put these in but inherited them from the previous owner. They are a nightmare to deal with. Thank you for your help.

If you have advice for Dale or Teresa, leave a comment below.

Spring tree care

The following is by Linn County Master Gardener, Claire Smith:

 

    March marked the start of our transition from winter to spring.  Now that the snow has melted  (we hope,)  it’s a good time to examine your trees for winter damage.  We often expect our trees to be self sufficient and  tend to neglect their well-being.  

     After the frost is gone, thoroughly water trees that have been subjected to de-icing compounds.  This will move the chemicals through the soil and away from the tree roots.   Watering before the ground thaws will create runoff and pollute soil and ground water. 

     If your trees need to be fertilized, wait until the ground has completely thawed.  Fertilizer run off wastes money and also contributes to groundwater pollution.

     If, and only if, an insect problem exists, dormant oil sprays can be used once the temperature reaches a constant 40 degrees.  Dormant oils are used to control some scale insects and overwintering insects. 

    Rabbits and voles girdle trunks at the base.  Damage will appear as a lighter area on the trunk, primarily as teeth marks.   The damage interrupts the flow of water and nutrients to the roots.   While you have no recourse for the damage, it is wise to monitor the health of the tree as severe damage can kill a tree.

    Tree wraps should be removed in the spring as the temperature warms.

    Complete pruning prior to trees leafing out.  Storm damaged branches should be removed as they occur. 

    If you’re planning on adding trees to your landscape, now is a good time to visit our local nurseries and greenhouses for suggestions and recommendations.        Personally, I’m going to find the shadiest spot under the big walnut to plant my chair and enjoy my favorite summer beverage.

Technically, it’s still winter

Several warm and sunny days this week might make us forget that winter is still with us, officially, at least, until Friday. Deb Engmark, head gardener at the historic Brucemore estate in Cedar Rapids, sent the following about this time of year:

   From the Brucemore Gardens

 

   The lengthening of the days and the warmer temperatures make me want to go outside and get back to gardening along with the rest of the grounds crew here at Brucemore. We have pruned all the deciduous trees and grape vines. The lawns and garden beds have been raked and the orchard will be pruned this week. While failing to pull the greenery used for holiday decorating out of a still frozen container, a somber realization dawned on me: it is still winter and there is a good month left before the real gardening can begin, and before we know it, the whole growing season will have passed by in a blur of continuous activity.

 

In my haste to hurry up and get busy, I realized that I had almost missed it again—the experience, the wondrous process of late winter merging into spring. With every rain drop and ray of sunshine, change is taking place. We all know this but rarely take the time to observe and enjoy. This year I vow to observe and enjoy with total presence, and I will stay conscious and aware during every season and transition of the year. Through Cindy’s blog, (thank you Cindy) I will share my experiences and offer tips and ideas for you to use in your own gardens.

 

I encourage you and yours to participate wholeheartedly also. Come visit the Brucemore gardens and grounds to experience the seasons this year. Our gates are open during regular business hours, 8:00 a.m. to 5:00 p.m. and often from dawn to dusk. Stroll the grounds, formal gardens, pond, timber, and orchard. Stop by the children’s garden to pick up a monthly activity sheet, which offers suggestions for additional nature study opportunities.

 

I would love to hear what you are doing also!  Please feel free to send me any suggestions, ideas, or tips from your own gardens and explorations.

Spring pruning tips

Richard Jauron, extension horticulturist at Iowa State University, offers the following on spring pruning of berries and other small fruits:

Small fruits that are commonly grown in home gardens include raspberries, grapes, gooseberries, currants and blueberries. For maximum production, small fruit crops need to be pruned in late winter/early spring (March/early April). Proper pruning procedures for raspberries, grapes, gooseberries, currants and blueberries are outlined below.

Raspberries
The pruning procedures for raspberries are based on the growth and fruiting characteristics of the plants.

Summer-Bearing Red Raspberries
Remove all weak, diseased and damaged canes at ground level in March or early April. Leave the most vigorous canes, those approximately 1/4 inch in diameter when measured 30 inches from the ground. After thinning, remaining canes should be spaced about 6 inches apart.

Also, prune out the tips of the canes that have died due to winter injury. Cut back to live tissue. If the canes sustained little winter dieback, remove the top 1/4 of the canes. Cane-tip removal or “heading-back” prevents the canes from becoming top heavy and bending over under the weight of the crop.

Red raspberries sucker profusely from their roots. Plants should be maintained in a one- to two-foot-wide hedgerow using a rototiller or spade. Remove or destroy those shoots that emerge outside the one- to two-foot-wide hedgerow.

Fall-Bearing Red Raspberries (Two Crop System)
Follow the same pruning procedures as described for the summer-bearing red raspberries. This pruning option provides both a summer and fall crop.

Fall-Bearing Red Raspberries (One Crop System)
Prune all canes back to ground level in March or early April. While the plants won’t produce a summer crop, the late summer/early fall crop should mature one to two weeks earlier. Also, total crop yield is typically larger using the one-crop system versus the two-crop system.

Maintain the plants in a one- to two-foot-wide hedgerow.

Black and Purple Raspberries
Remove the small, weak canes, leaving only four or five of the largest, most vigorous canes per clump or plant. Cut back the lateral (side) branches to 12 inches in length for black raspberries and 18 inches for purple raspberries.

Grapes
Grapevines produce fruit clusters on the previous season’s growth. Before pruning, a grapevine may have 200 to 300 buds capable of producing fruit. If the vine is not pruned, the number of grape clusters would be excessive and the grapevine would be unable to ripen the large crop or produce adequate vegetative growth.

To maximize crop yields, grapevines are trained to a specific system. The most common training system used by home gardeners is the four-cane Kniffin system. The four-cane Kniffin system is popular because of its simplicity. In the four-cane Kniffin system, the canes of the grapevine grow on two wires, one located three feet above the ground and the second six feet high.

If using the four-cane Kniffin system, select four canes on the upper wire, two going in each direction. Also, select four canes on the lower wire. To aid identification, some gardeners tie brightly colored ribbons or strips of cloth on those canes they wish to retain. All remaining one-year-old canes should be completely removed.

Going back to the upper wire, select two of the remaining four canes (one going in each direction). Prune these canes back to one or two buds. These short one or two bud canes are referred to as renewal spurs. The renewal spurs provide the shoots or canes that will produce next year’s crop. Prune the remaining two canes on the upper wire back to eight to 13 buds. The number of buds left on the fruiting canes is determined by plant vigor. If the grapevine is vigorous, leave 13 buds per cane. Leave only eight buds per cane if the grapevine possesses poor vigor.

Prune the four canes on the lower wire the same as those on the upper wire. When pruning is complete, no more than 60 buds should remain on the grapevine. When counting the number of buds on the grapevine, include both the buds on the fruiting canes and those on the renewal spurs.

Gooseberries and Currants
Gooseberries and currants produce the majority of their fruit on 2- and 3-year-old shoots. Shoots that are 4 years old and older produce very little fruit. After the first growing season, remove all but six to eight vigorous, healthy shoots. The following year, leave four or five 1-year-old shoots and three or four 2-year-old canes. After the third growing season, keep three or four shoots each of 1-, 2-, and 3-year-old growth. A properly pruned, established plant should consist of nine to 12 shoots. Pruning of mature plants consists of pruning out all 4-year-old shoots and thinning out some of the new growth.

Blueberries
Blueberry plants are shrubs like currants and gooseberries. Blueberry yields and fruit quality decline when blueberry shoots (stems) reach 5 years of age. In late winter/early spring, prune out any dead or diseased stems. Also, prune out stems that are 5 years old and older. Allow one to two new shoots to develop each year.

The pruning of small fruits really isn’t difficult. It requires a basic understanding of plant growth and pruning techniques, proper pruning equipment and (sometimes) a little bit of courage.
