Hydrangeas grace the landscape with beautiful flowers in the spring and summer. The most colorful hydrangeas are bigleaf hydrangeas, Hydrangea macrophylla. Their flowers are usually either pink or blue. Flower color depends on the pH of the soil, a measure of soil acidity. Soil pH can be raised by applying lime. Some hydrangeas will respond to a higher pH (between 6.0 and 6.5) with pink flower color. To lower pH, apply aluminum sulfate. A lower pH (between 5.0 and 5.0) often results in blue flower color. A soil test will determine the existing pH and you can change your soil with the appropriate amendment to get the resulting flower color you want. Continue reading

Sometimes considered large shrubs, serviceberry trees are usually grown in clumps with many upright branches, although they can be trained to a single trunk. They reach sizes of 25 feet tall by 15 to 20 feet wide. Amelanchier is one of those trees whereby the common name can sometimes make it difficult to identify. In addition to serviceberry, these trees are also known by Saskatoon, shadblossom, shadbush, shadwood, Juneberry, mountain blueberry, or sarvis-tree. Being a native tree to woodland borders and hillsides in eastern North America, settlers who encounter and admired Amelanchier contributed to the multiple common names it now carries. One name, serviceberry, originated because branches were collected in mid-winter and forced into bloom for church services. Continue reading
