The cherry - tip genus Photinia is a wide cultivated landscaping shrub , with deep immature matured folio , brilliant ruby unexampled outgrowth and white blossom . It ’s often used as a privacy hedgerow , as it originate very thick and to a height of 12 feet if leave behind unpruned . crimson - tip genus Photinia is prostrate to yellowing of the farewell in between the folio vena , a status foretell greensickness , which is caused byiron deficiency . Chlorosis is specially likely in alkaline soil , which is common in the westerly part of the United States .

Step 1

Inspect the industrial plant for branding iron chlorosis symptom . The leaves will yellow in a classifiable pattern , leaving the leafage vena unripe . atomic number 26 deficiency chlorosis will start in the new foliage , working through older farewell if left untreated .

Step 2

utilize chelate iron to the industrial plant in the form of leaf spray or granular supplement , following packet direction . These can be found in any garden centre or nursery .

Step 3

Work peat moss into the soil for long - term discussion of chlorosis . This acidic addendum balances the alkaline soil , improving the power of the plant to absorb iron .

Step 4

Improve soil drainage to increase resistance to greensickness . Wet soil prevents plant root from absorb enough atomic number 8 , leaving them ineffectual to take up iron . Working mulch or compost into the soil can meliorate drainage .

Step 5

Apply only scurvy - phosphorous fertilizer . Excess phosphorous can block iron uptake by the plant . Phosphorus content is indicated on the fertilizer package by the middle turn in the three - number indicant of fertiliser grade .

Confirm your photinia bush ' greensickness symptom play off those of smoothing iron inadequacy . In contrast , nitrogen - lacking leaves , admit the veins , turn over pale yellowish , and older leaves show that symptom first . reprise the atomiser app three to five times throughout the year if necessary . Foliar coating of a melted iron mixture bring home the bacon shrub with warm but short - lasting alleviation from branding iron chlorosis . Keep soil well - drained and never soggy . Cold temperatures slow genus Photinia root natural action and make iron deficiency more pronounced , particularly when geminate with poor water management . try the photinias ' soil pH level annually , send soil sample to a laboratory .
