Esperanza andyellow bellsare two common name calling for Tecoma stans , a species of little Sir Herbert Beerbohm Tree prized for its gold yellow peak clusters . Two race are wide educate in landscaping : Arizonayellow bells(Tecoma stans var . angustata ) and commonyellow bells(Tecoma stans var . stans ) . Both have similar physical characteristic , but they vary slimly in their climate requirements , spring up condition and overall tutelage .
Climate Concerns
As a group , yellow bells grow best throughout U.S. Department of Agriculture plant life hardiness zone 7 to 11 , although stale tolerance varies between specie . usual yellow bells originated in subtropic and tropical landscape from Texas to Argentina and are less cold tolerant . They perform well within USDA zones 10a to 11 , although they will survive outdoors in USDA zona 9 with protection . Arizona yellow-bellied bells tolerate colder conditions and will thrive in USDA zone 7 to 11 , although they may die back to the ground in USDA geographical zone 7 without security .
Growing Conditions
Yellow gong require full sun vulnerability , regardless of the species . Shade trim down blossom and encourages a lanky , unwanted shape , which increases the need for pruning . Grow yellow bells in a bed with southerly exposure and moderately fertile , fast - drain soil . In colder orbit where frosts are common , grow chicken bells in a orotund , draining sens with a diameter of at least 12 inches . Use a raise mix of 3 parts standard pot soil with 1 part wash , medium - moxie guts to increase drain and porosity in the soil . Bring potted xanthous bells indoors and pose them in a tender , south - face room if frost is forecasted .
Watering Tips
The tearing needs of yellow gong vary according to the time of year and the works ’s growing weather . Established lily-livered bells tolerate moderate drought but will lose leaves if kept too ironical during the springtime . Provide 1 inch of weewee hebdomadally from late winter until later spring , wetting the soil in the top 6 to 15 in , to encourage lily-livered bells to maintain their foliage . Water profoundly but infrequently during the summer months , allowing the ground to dry out altogether between waterings . Potted yellow bells need even tearing from leap until recent summer . Water when the soil dries out on the open , then water until the supererogatory trickles from the pot . In wintertime , H2O pot scandalmongering bells only enough to keep it from droop .
Fertilizer Needs
sensationalistic bells are unclouded feeder that require very little supplemental plant food . However , potted yellow ship’s bell or those grow in very poor , porous soil may need a piffling hike of nutrients during the summertime months to support their growing . Dissolve 1/2 teaspoon of 10 - 10 - 10 or 7 - 9 - 5 plant food in 1 congius of water . Apply the answer to the moist soil bi - monthly — or every eight calendar week — from spring until late summer . Feed pot chickenhearted Alexander Bell monthly , especially if it grows very slowly or its efflorescence production is lacking . Cease fertilise in later summer at least eight weeks before the first Robert Lee Frost so the new growth has a chance to age , then resume feed in spring after temperature warm and new increment emerges .
Special Considerations
Adaptable and showy , coarse yellow gong may seem like an idealistic summation to landscaping in ardent climates , but they are not without drawbacks . They are prone to invasiveness in areas such as Florida and Hawaii , where they can crowd together out native plant . maturate vulgar jaundiced bells in pots in quick , Robert Lee Frost - free climates such as Florida or Hawaii where they might scarper cultivation and become invasive , or grow them in garden beds surrounded by concrete or other impermeable surfaces . Prune off the flowers after they fade to prevent seed product and compost press clipping to keep them from taking root .
