Short-Lived Trees
Some trees naturally live longer than others but, ironically, many of the most popular landscape trees tend to be relatively short-lived. Although their flowers are quite attractive, Bradford or Callery pears are generally considered short-lived trees, and they are also highly invasive.
Entomosporium leaf spot on Photinia (Red Tip). Small reddish leaf spots appear initially. As spots age, center is grayish with a dark purple border. Leaf spots may coalesce causing severe leaf blight. Severely infected leaves drop prematurely. Over time severely infected plants die. Infection is favored by poor air circulation and prolonged periods of leaf wetness. CAES News
Leaf spot disease
Excessive rain signals another a bad year for leaf spot diseases on landscape trees and shrubs. The leaf spotting that affects pear trees, including both edible pears and ornamental Bradford types, is caused by a fungal disease known as Entomosporium leaf spot. This disease also affects related shrubs such as Indian hawthorn and red tip photinia.

Master Gardener
John Ruter realized at a young age that he belonged in a garden.

Arbor Day
Nationally, Americans recognize Arbor Day in April. However, Georgia celebrates Arbor Day on the third Friday of February each year because this is a better time to plant trees, giving roots time to grow before the heat and drought of our summer months.

Winter Bloomers
I find it ironic that Valentine’s Day occurs in February, a time of the year when we see very few plants blooming in the landscape. In addition to cards and candy, flowers are one of the most popular gifts during this annual celebration of love. In 2018, the Society of American Florists estimated that 250 million cut roses were produced for Valentine’s Day and an estimated 35% of Americans purchased flowers.

Cultivating Southern firs
During the holiday season in the U.S., more than 20 million freshly cut Christmas trees are sold every year, with fir trees topping the most-desired list. Unfortunately growers cannot meet the needs of consumers, and every year, there is a shortage of trees, primarily due to the incredible losses of susceptible firs — including balsam, Fraser, Canaan and others — to the root fungus Phytophthora.

Year-round Beauty
As vibrant holiday plants begin to adorn the shelves of hardware stores, grocery stores and garden centers, consumers are attracted to the pinks, reds and whites atop deep green foliage, which add festive pops of color in winter homes. The appearance of plants like poinsettias and Christmas cacti usher in the holiday season and we love to fill our halls and entryways with their holiday cheer. But what about after the holidays?
