These cultivars are highly susceptible to leaf spot: Bloom time is about 2 weeks later than other Indian hawthorns. Spring Sonata™ (‘Wilcor’ PP17972) grows to 4 feet tall and 5 feet wide with white flowers.The flowers are pure white, and the leaves are light green. ‘Snow White’ is a dwarf form with a spreading habit to 3 to 4 feet tall by 4 to 6 feet wide.Rosalinda® (‘Conda’ PP9056) is typically grown as a tree form, and reaches 10 to 12 feet tall by 8 to 10 feet wide.It grows to 4 feet tall and 4 to 5 feet wide with white flowers. Olivia™ (‘Conia’ PP9399) is one of the most disease resistant Indian hawthorns.The large leaves have good resistance to leaf spot. Majestic Beauty® (‘Montic’ PP3349) grows to 8 to 10 feet tall or more by 5 to 10 feet wide with fragrant light pink flowers.This cultivar is one of the most resistant to leaf spot. Indian Princess® (‘Monto’ PP5862) grows in a compact, mounded form with pink flowers that fade to white.Gulf Green™ (‘Minor’) grows 3 to 4 feet tall by 3 to 4 feet wide with white flowers.It has good resistance to leaf spot and is cold hardy to 5 ☏. ‘Georgia Petite’ (PP9983) bears blooms of light pink and white and grows to 2½ feet tall and 3 feet wide.‘Georgia Charm’ (PP9982) bears white blossoms and grows to 4 feet tall and 3 feet wide.‘Eskimo’ grows up to 6 feet tall and 8 feet wide with white flowers. ‘Eskimo’ is cold tolerant to 5 ☏, and exhibits very high resistance to leaf spot.‘Eleanor Tabor™’ (‘Conor’ PP9398) is a pink-flowered cultivar that has very good leaf spot resistance, unless planted in less than 6 hours of sun.‘Clara’ is white flowered, with reddish new growth that matures to dark green.
#Indian hawthorn full
The leaves turn deep purple in winter if grown in full sun. It has white flowers, and deep blue fruit. ‘Blueberry Muffin’ is very cold hardy with good root rot and foliage disease resistance.
The best way to prevent leaf spot on Indian hawthorn is to plant selected resistant cultivars (see below), grow them in a full sun site, and use drip irrigation. For this reason, red tip photinia is rarely still found for sale. This same disease also affects red tip photinia and pears (such as Bradford pear), but may also be found on pyracantha, quince and loquat. Test the soil in landscape beds for proper fertilization. Plants weakened by stresses from improper fertilization and irrigation, exposure to lawn weed killers, and foliar disease may be more apt to be damaged by cold weather. Severe defoliation may occur during summer following a heavy infection with Entomosporium leaf spot on Indian hawthorn ( Raphiolepis species). Winter injury has become more common, and was quite severe during the winter of 2014-2015, where many Indian hawthorns in South Carolina were See Table 1 for examples of brands and specific products. Follow label direction for rates and safety. Addition sprays may be needed in the fall. Spray every ten days during rainy spring weather, or every two weeks during dry spring weather. Collect and discard fallen diseased leaves during winter, and then mulch the shrubs.ĭiseased shrubs may be sprayed with Daconil (chlorothalonil) beginning when new leaves first appear in spring until early June. If sprinklers are used, only water established plants once per week as needed during the growing season and apply one inch of irrigation water each time. Water shrubs with drip irrigation rather than overhead sprinklers. Slow the spread of disease by properly spacing plants to improve air movement. Severe infections may result in early leaf drop.
These expand and on heavily diseased leaves, merge, forming large, irregular blotches. The first symptoms are tiny, round, red spots on both the upper and lower sides of young leaves.
