Watson2</p><p>INTRODUCTION</p><p>Yoshino Cherry grows moderately fast to 25 feettall and a bit wider, has beautiful bark marked withprominent lenticels but is a relatively short-lived tree(Fig. 1). It has upright branching when young formingmore horizontal branching with age, making it idealfor planting along walks and over patios. The white tosoft pink flowers which occur in early spring beforethe leaves develop are sometimes damaged by latefrosts or very windy conditions. This is one of thespecies (along with Kwanzan Cherry) in Washington,DC, which makes such a show each spring.</p><p>GENERAL INFORMATION</p><p>Scientific name: Prunus x yedoensis AkebonoPronunciation: PROO-nus x yed-oh-EN-sisCommon name(s): Daybreak Yoshino CherryFamily: RosaceaeUSDA hardiness zones: 5B through 8A (Fig. 2)Origin: not native to North AmericaUses: Bonsai; recommended for buffer strips aroundparking lots or for median strip plantings in thehighway; near a deck or patio; shade tree; specimen;no proven urban toleranceAvailability: somewhat available, may have to go outof the region to find the tree</p><p>DESCRIPTION</p><p>Height: 25 to 35 feetSpread: 25 to 40 feetCrown uniformity: symmetrical canopy with aregular (or smooth) outline, and individuals have more</p><p>or less identical crown formsCrown shape: round; vase shapeCrown density: moderateGrowth rate: mediumTexture: medium</p><p>Foliage</p><p>Leaf arrangement: alternate (Fig. 3)Leaf type: simpleLeaf margin: double serrate; serrateLeaf shape: elliptic (oval); obovate; ovateLeaf venation: banchidodrome; pinnateLeaf type and persistence: deciduousLeaf blade length: 2 to 4 inchesLeaf color: greenFall color: yellowFall characteristic: showy</p><p>1.

Foliage of Daybreak Yoshino Cherry.</p><p>Best used as a specimen or near the deck or patiofor shade, Yoshino Cherry also works nicely alongwalks or near a water feature. Not a street or parking</p><p>lot tree due to drought-sensitivity. Large specimenstake on a weeping habit with delicate branchletsarranged on upright-spreading branches affixed to ashort, stout trunk. A lovely addition to a sunny spotwhere a beautiful specimen is needed. Winter form,yellow fall color, and pretty bark make this a yearround favorite.</p><p>Provide good drainage in an acidic soil for bestgrowth. Crowns become one-sided unless they receivelight from all around the plant, so locate in full sun.Select another tree to plant if soil is poorly drained butotherwise Yoshino Cherry adapts to clay or loam.Roots should be kept moist and should not besubjected to prolonged drought.</p><p>Other cultivars include: Perpendens - irregularlypendulous branches; Shidare Yoshino (Perpendens)- irregularly pendulous branches.</p><p>Pests</p><p>Aphids cause distortion of new growth, deposits ofhoneydew, and sooty mold.</p><p>Borers attack flowering cherries under stress.Keep trees healthy with regular fertilizer applications.</p><p>Scales of several types infest prunus. Horticulturaloil can be used to help control scale.</p><p>Spider mites cause yellowing or stippling but arevery difficult to see. They are usually recognized onlyafter plant symptoms are quite advanced.</p><p>Tent caterpillars make large webbed nests in treesthen eat the foliage. One defoliation may not beserious and small nests can be pruned out anddestroyed. Use Bacillus thuringiensis when the insectsare first seen and are still small.</p><p>Diseases</p><p>A bacterium causes leaf spot and twig cankers oncherry. Small, reddish spots dry, and drop out, givinga shot holed appearance. Defoliation can be severewhen conditions favor disease development. Fertilizeinfected trees and prune out infected branches.</p><p>A fungus causes reddish spots which drop outleaving shot holes. Once the hole appear the leavesmay drop. The disease is worse in wet weather.</p></li><li><p>Prunus x yedoensis Akebono -- Daybreak Yoshino Cherry Page 4</p><p>Black knot causes black swellings or galls on thebranches. Branches with galls are pruned out.</p><p>Powdery mildew causes a white coating on theleaves.</p><p>Yoshino Cherry may be subject to witches broom.Branches are deformed and clusters of small branchesform. Infected branches bloom and leaf out earlier.Brooms are pruned out, to help control the disease.</p></li></ul>
