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 Posted on 09/20/21 by Paul Pugliese
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.

Winter Bloomers Posted on 02/11/21 by Paul Pugliese
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.

Would you like to enclose your backyard so that you can enjoy your coffee on the patio without your neighbor’s security camera spotting your pajamas?

'Kanjiro' Camellia Posted on 01/16/18 by Norman Winter
In Japanese, the word “kanjiro” means “you must feel.” I’m not sure if that means “to touch” or “to experience,” but the ‘Kanjiro’ camellia is certainly one to experience. The ‘Kanjiro’ camellia is known botanically as “Camellia hiemalis” and debuted in 1954. The longevity of this camellia cultivar, which is entering its 64th year, is a testament to both its character and performance in the landscape.

This time of the year, everyone is thinking of decking the halls with hollies and their colorful red berries, but you just may want to consider adding a touch of gold. Can you even imagine hollies with bright golden berries? These would show out in the landscape like small trees or shrubs adorned with a thousand little golden lights — and the same for the mantel! My preference, however, would be to see birds celebrating with a Christmas feast.
