Hello and thank you for contacting Ask Extension. Looking at your pictures, I believe your serviceberry is experiencing leaf scorch from transplant shock. Leaf scorch is a common symptom of transplant shock. Leaf scorch first appears as a yellowing or bronzing of tissue between the veins or along the margins of leaves of deciduous plants (those that lose their leaves in winter). Later, the discolored tissue dries out and turns brown. Other symptoms of transplant shock appear as wilting leaves (especially on recent transplants), yellowing, and leaf rolling or curling. If stress is not alleviated, leaf death occurs and may be followed by twig and limb dieback. The fact that your tree came back this year is a good sign so I would give it another year and concentrate on proper watering based on your soil type. It takes a few years for woody plants to settle in and become established in the landscape

Proper watering after transplanting is especially critical in the first year; over watering is just as injurious as under watering. Soil type and amount of rainfall will determine the frequency and amount of water needed. During the growing season, landscape plants in well-drained soils should receive at least one inch of water per week. Plants in poorly drained soils will require less frequent watering. Use a garden sprinkler or soaker hose and measure the amount of water applied (you can use a tuna fish can placed on the ground near the tree to measure irrigation water). Some kind of mulch can also help your soil maintain moisture. Make sure to leave a circle around the stem where there is no mulch. This will help prevent the trunk from rotting.

Transplant shock is a term that refers to a number of stresses occurring in recently transplanted trees and shrubs. It involves failure of the plant to root well, consequently the plant becomes poorly established in the landscape. New transplants do not have extensive root systems, and they are frequently stressed by lack of sufficient water. Plants suffering from water stress may be more susceptible to injury from other causes such as the weather, insects, or disease. When several stresses are being experienced, the plant may no longer be able to function properly.

One of the most common causes of plant root failure is "wet feet" caused by improper soil amendments--the "bathtub effect." When planting in heavy soil, be sure to use the same heavy soil to fill the planting hole. Many gardening books suggest adding peat moss or other amendments to the back fill. This is not recommended. A light soil mix placed where it is surrounded by heavy soil too often results in trapped water, suffocated roots, and eventually a dead plant.

Planting depth is important. Deep planting results in suffocated roots while shallow planting causes root stress from the more extreme temperature and moisture fluctuations in shallow soil.

Problems can result from failure to spread roots of container grown plants. Such plants often have roots that are coiled around the inside of the pot. Gently uncoil and spread the roots apart before planting. If this is not done, circling roots can eventually girdle or strangle the trunk as the roots increase in diameter with growth.

Always remove twine, rope, or wire from the trunk at planting time to prevent strangulation of the tree as it grows.

Serviceberry trees are mainly woodland plants that prefer full sun to partial shade. They should be planted in rich, moist, well-drained soil. They are prone to the same pests and diseases as apples and pears, including fireblight, and can serve as a host for cedar-quince rust, cedar-serviceberry rust, and cedar-hawthorn rust, which are caused by Gymnosporangium species. I do not think your serviceberry has either of these problems but just in case it does develop these symptoms later you will have some information about what to do to prevent it from killing your serviceberry.

Fire blight

• Infected leaves wilt, turn gray then dark brown to black
• Young shoots wilt into a shepherd's crook
• Infected blossoms first turn gray, then black
• Infected leaves and mummified fruit remain attached to the tree, often into winter
• Branch cankers have dark, sunken and cracked bark, sapwood is streaked reddish brown
• Drops of sticky honey-colored liquid can be seen on infected plant parts in warm wet weather

Several rust diseases can infect serviceberries as well. Cedar-quince rust, cedar-hawthorn, and cedar-serviceberry rust can cause leaves to wilt, small branches to die, and may produce orange growths on fruit, making them inedible. Berry spots or leaf spots caused by a fungus known as Entomosporium creates angular spots with a yellow border on leaves and deforms fruits.
