The evergreen plant genus Euonymus is a common plant used in hedges across the U.S. The most pop cultivar ( Euonymus japonicus’Aureomarginatus , ' USDA hardiness zone 6 to 9 ) has variegated yellow - green leave that give the plant its " prosperous genus Euonymus " moniker .
As with most woody evergreen shrubs , euonymus ( which is not only its botanical name but also its common name ) requires veritable maintenance , fertilizer and pruning — but the most significant prospect of this shrub ’s fear is to ensure proper pH , as it is intolerant of too - alkaline soils .
About Euonymus Shrubs
While the most popular and usable golden euonymus bush are cultivar of the Japanese euonymus , Euonymus japonicus , multiple other specie exist , include wintercreeper ( Euonymus fortunei’Emerald n Gold ' ) anddeciduous groundcoverssuch asEuonymus obovatus .
All metal money prefer full sun but can benefit from somepartial shadeduring hot afternoons to limit sun exposure . Like most plants , they call for well - draining dirt .
These are with child landscape painting shrubs , typically reach 10 to 15 invertebrate foot mellow and 5 to 8 foot wide , but they lend themselves to heavy pruning and can be maintained .
Fertilizing Golden Euonymus
While landscape painting plants like gilded euonymus are jolly small maintenance , attention to key aspects of its care will help ascertain a healthy shrub .
Soil pH
First , the correct soil pH is significant for euonymus shrubs , because soil types that are too alkaline can result in chlorosis , a yellowing of the leave from iron insufficiency . To see to it the right environment , get a soil test , available from most nurseries or your local university extension service office .
- The idealistic pH for euonymus is 6.5 to 7.0 , * * reportsMississippi State University . If your test reveals an alkaline pH mellow than 7.0 , add sulfur to depress the pH and a liquid , concentrated pattern of iron and zinc to supply the leave out micronutrients .
Fertilizer
Euonymus shrubs can be for years and are in it for the long haul . Woody trees and shrubs grow best when provided in high spirits - atomic number 7 fertilizers rather than balanced fertiliser . This is because most soils retain phosphorus and potassium over metre , while N can be depleted — but a soil run will tell you for sure .
- In most vitrine , you are looking for a coarse-grained fertilizer mixture with an NPK ratio such as 4 - 1 - 1 , 15 - 5 - 5 or 24 - 8 - 16 , * * in which the first telephone number represents the percentage of atomic number 7 , the 2d phosphorus , and the third K .
Warning
If fertilized with an nimiety of atomic number 7 , euonymus can revert to a green form rather than maintaining a variegated appearance , so if this begins to fall out , back off on the atomic number 7 for a year .
calculate for irksome - release granular fertilizer to control a tedious , steady consumption of nutrients and uniform maturation . Organic fertilizers take longer to break in down and are a respectable bet to combat poor grime and work up up fecundity in the recollective run .
