Full
sun (southern exposure) or partial sun (east or west exposure).
Temperature:
As
a potted plant, maintain indoor temperatures above 60°. They can be
grown cooler but this will slow growth and can put them into a semi
dormancy.
Humidity:
Preferably
50% or higher; however they will tolerate low levels with no harm.
Watering:
Bring
soil to visual dryness between waterings. When watering, thoroughly
saturate soil until a little water runs out of the bottom of the pot.
Fertilizer:
They
need moderate levels of fertilizer. Give them more under high light.
Generally fertilize with ˝ tsp./gallon once a week. Excessive
fertilization can disrupt blooming. Us a balanced fertilizer i.e.
15-15-15 or a blooming fertilizer like Pro Gro ‘Grow’ 7-9-5 or
Electra 5-10-3.
Pruning:
Prune
after flowering in the fall so as to not disrupt the blooming cycle as
flowers for on the tips of the vining growth. As it is an aggressive
vine the climbing leads can be selective removed any time to manage it
size.
Insects and
Disease:
It
has some susceptibility to mealybugs.
Comments:
Petraeovitex
is an unusual and spectacular climber that’s easy to culture. We
flower them in 10” on 3’ stakes. A little training is needed
wrapping the vines around itself allowing the pendulous chains of
bloom to cascade off of the plant. The root system is strong having no
problems with root disease. Remember flowers form at the tips of the
growing vines from spring to fall.
