Purdue Landscape Report: J. Sterling Morton had a strong enthusiasm for trees and advocated intensely for individuals and civic groups to plant them. Once he became secretary of the Nebraska Territory, he further spread his message of the value of trees and Morton first proposed a tree planting holiday to be called “Arbor Day” at a meeting of the State Board of Agriculture.

The celebration date was set for April 10, 1872. Prizes were offered to counties and individuals for the largest number of properly planted trees on that day. It was estimated that more than 1 million trees were planted in Nebraska on the first Arbor Day.

Many other states also passed legislation to observe Arbor Day each year. By 1920, more than 45 states and territories were celebrating Arbor Day. The tree planting tradition became prominent in schools across the nation in 1882, with students were learning about the importance of trees as well as receiving a tree to plant in their own yard. They continue to do so today in many states.

Celebrate arbor day by planting a tree!

Question: I am actually a Master Gardner in Hamilton County and I need help with a tree bark damage question. We have a beautiful dogwood tree that is about 18’ tall and 6” in diameter. By accident my husband backed into the tree with his truck while unloading mulch – he did not see it! Now there is severe damage to the bark at the bumper height – about 3” wide and 14” long. All the way down the bark is gone.

What are the chances the tree will survive? What if anything should I do at this point?

My husband wanted to cover it with painter’s tape to protect it but I know that is not good for the tree. Please let me know your suggestions as I do hope to save the tree if possible.

Answer: Well, that is certainly an unfortunate accident for the tree! There may be a rescue treatment worth trying that research has shown promise in sealing the wound. The ability for the tree to seal and close off wounds is based on species, age and energy resources. Additionally, follow these instructions…

1. Keep the tree healthy; mulch and supplemental watering during drought conditions.
2. Trace the wound with a wood file and sharp knife, removing any loose bark to a clean wound.
3. Take black plastic and attach it to the tree wound, just past the wound edge, using small, ¼” staples from a staple gun.
4. Attach the plastic so that it forms a seal which will help to maintain a moist environment for parenchyma cells to do their work at compartmentalizing and creating wound wood on the perimeter of the damaged area.
5. The plastic may need to be checked periodically to be sure it is attached well until removal.
6. Leave the wound covered for about 12 months, then remove carefully.

This will not guarantee recovery, but research has indicated it does facilitate healing more quickly in many species. Continue to monitor for health and recovery.

Good luck!

It’s time to meet another native Indiana tree. This time Purdue Extension forester Lenny Farlee brings you the Umbrella Magnolia. This small tree is easily identified by the clusters of long simple leaves at the end of the twigs, which form an umbrella shape.

In this episode of ID That Tree, Purdue Extension forester Lenny Farlee continues to talk about the oak groups, this time focusing on the black oak species. Deep sinuses on the leaves and shinier coat, a dark blocky bark and acorns with loose shingle-like plates on the cap are some key identifiers to separate it from the red oak and others.

The goal of extension work is to provide practical solutions to local – and global – issues from agricultural production, environmental issues, natural resource conservation, land use and more.

Purdue Extension wildlife specialist Jarred Brooke’s work with prescribed fire is doing just that, as it is now being used to educate a new audience about various techniques of the habitat management method, the Wounaan indigenous community of Panama among others, thanks to the United States Forest Service.

Naomi Mills, a smokejumper squad leader for the Missoula Smokejumpers and fire specialist for USFS International Programs in the Latin America region, is utilizing Brooke’s Wildlife Habitat Hint series on prescribed fire techniques to illustrate various ignition techniques and methods as part of her virtual fire management training sessions.

Figure 1: A spruce tree suffering from root damage and water stress.

Figure 4: Phomopsis dieback with excessive needle loss on branch tips.

Figure 3: Dieback symptoms in a mature tree associated with Phomopsis infection.

The disease begins in the lower canopy and moves upward, but in some cases it progresses quickly, causing dieback through a large portion of the tree. Besides needle death and drop, there are virtually no other external symptoms to indicate where the original infection took place. Occasionally you may find resin building on the outside of a canker. Cutting into the thin bark will show the brown discolored tissue where the canker is developing. Cankers are often located in between two areas of healthy tissue. This can lead to older needle loss similar to needlecast diseases, but leaving terminal buds alive. However, once the pathogen spreads and girdles the branch, the rest of the branch will begin to die out to the tip.

Question: We live in Tippecanoe county and need to transplant a tulip tree that is 2-3’ tall. Could you please tell me when the optimal time would be to transplant? I have read to transplant in the spring, but would like more specific information, so that it will have a good chance of surviving.

Answer: Early spring (before leaves emerge) and fall (after leaf drop) are the best times to transplant deciduous trees. Evergreens are most successfully transplanted in early spring and late summer (late August to mid-September).

Dig and move trees with the soil root mass adhering to portions of their root systems to minimize damage and improve chances of survival. The soil should be moist when the plant is dug. If the soil is dry, thoroughly water the area 3 to 4 days before digging. When digging trees, the radius of the root ball should be approximately 8 to 12 inches for each inch of trunk diameter at chest height. For example, a tree with a 1-inch-diameter trunk should have a soil ball that is 16 to 24 inches in diameter. Using a spade, dig a trench around the tree to a depth of 1½ to 2 feet. Then cut beneath the roots, rounding the bottom of the soil ball. Tip the soil ball to one side, place a piece of burlap or a small tarp in the trench on the opposite side, then carefully tip or roll the soil ball over onto the burlap. IMPORTANT! Manipulate the ball by the root/soil mass and NOT the tree trunk. Tightly secure the burlap or tarp around the soil ball to move it to its next home. Lift and carry the root ball rather than grasping the trunk. If transporting in a vehicle at speeds, be sure to cover the tender buds with a tarp to protect them from drying out.

If possible, replant the tree immediately. Dig a hole that is 2 times the width of the tree’s rootball. The depth of the hole should be 2 or 3 inches less than the height of the soil ball. Be sure the root flare is visible to get the exact depth. Carefully lower the tree into the hole, position it correctly, and begin to place soil back into the hole. Firm the soil around the tree’s rootball with your hands. Then complete the backfilling of the hole and water thoroughly.

Do not allow the soil ball to break during the digging, moving, and replanting process. Home gardeners should limit themselves to transplanting small trees. Trees with a trunk diameter greater than 2 inches should be left to nursery professionals.
Post-planting should include supplemental watering and no fertilization for the first year. Staking or guying may be necessary in vulnerable areas such as exposed or windy sites. Finish with mulch and monitor for pests and dry conditions.
