Amelanchier Rainbow Pillar

(Question)

imageWe planted the above shrub/tree in May and I just noticed that the interior leaves have turned yellow and are dropping.  What is the problem and what is the solution. It is about 4 feet tall.

(Answer)

It is not unusual for an Amelanchier canadensis ‘Glenn Form’ Rainbow Pillar, commonly known as a Serviceberry, to loose some of its older (interior) leaves, especially after being newly transplanted, if otherwise the leaves do not show any signs of disease.  It takes some time for a newly planted tree or shrub to establish its root system in the new environment.  During this time it is especially sensitive to too little, but also to too much water.  It is important that you keep the soil evenly moist throughout the first two growing seasons.  Water regularly when needed, this is when the soil near the stem is dry down to the first inch.

I hope you will be able to enjoy your Amelanchier for a very long time.
