Evergreens offer yr - round coloring material and habitat for the hardy birds . They ’re attractive to developers and householder likewise for their easy care and modest alimentation requirements . Yews ( Taxus spp . ) are specially useful because of their sonant foliage and ability to regrow after terrible shearing . Their only drawback is their toxicity , so embed them well away from play area and livestock .
Versatile Yews
English yews(Taxus baccata ) , hardy only in U.S. Department of Agriculture industrial plant hardiness zone 6 to 7 , constitute the chummy , ofttimes sheared hedges of the temperate formal garden . Nipponese ( Taxus cuspidata ) and hybrid ( Taxus x medium ) , also called Anglojap , yews , hardy from USDA zones 4 through 7 , grow in a variety of forms that call for small pruning . The largest dimension of an private yew — either peak or width – hints at the amount of fertilizer it needs . old plant rarely need fertilizing — and too much fertilizer can stress even untested yews — so do a grease trial to determine actual nutrient needs .
What Yews Want
yew are slow - growing evergreens that have two growth spirt — one in early outflow and one as summer start . Prune before early leap ’s squirt to shape the bush and following their second jet to keep them compendious . If your yew exist in full sunlight to part shadiness , have a well - draining grease with a pH between 6.0 and 7.0 and get an in of water a week , chances are that they ’ll only need fertilizer while young . An annual mulch of well - moulder compost , diffuse underneath and beyond the drip line provides slow - waiver atomic number 7 , the food that celebrate yew producing green , levelheaded foliage . Keep mulch away from the trunk to keep away mold and wood - eat up being in the mulch . Never fertilise yews under stress , such as during drouth or take after overhaul .
Individual Plants
Timed release plant food provides a low , unremitting flow of nitrogen during the growing season , so pick out a gamy nitrogen , slow sack chondritic fertilizer for your yew . The Virginia Cooperative Extension recommends applying a 12 - 6 - 4 , 16 - 8 - 8 or 20 - 10 - 10 commercial fertiliser at the rate of 1/3 pound per foot of height or width of the plant , whichever is great , applied in early spring or previous fall — feed at both times for more aggressive maturation . Scatter granular fertilizer under the unseasoned yew and beyond its drip line of merchandise by half the diameter of the flora . Scratch it into the open of the ground and water well before mulch . Feed container - grown yews at 1/5 of this speciality — when using fluent fertiliser , dissolve 1 tablespoon in 5 gallons of water instead of the recommended 1 gallon and expend monthly during outpouring .
Large Plantings
Hedges , groups and heavy English yew — which can develop to 60 feet marvellous — require fecundation on a tumid graduated table . Again using granular , slow - release commercial-grade plant food , apply 1 to 2 pounds of nitrogen per 1,000 square feet of area covered by these big yew or groups of yews . A 20 - 10 - 10 fertilizer , for model , contains 20 pct nitrogen , so a 100 - Irish pound dish contains 5 pounds of N and you would take only 1/5 bag to treat a 1,000 - square - understructure surface area — say 100 feet of hedging .
