Light:

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 when under high light.  Generally fertilize with ½ tsp./gallon once a week.  Excessive fertilization can disrupt blooming.  Use 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:

When growth is excessive, prune back vining growth.  Hard pruning is tolerated with ease.  Remember that flowers form on young growth, so pruning will discourage blooming for a short time.

Insects and Disease:

Aristolochias are susceptible to mealy bugs.  Grandiflora is susceptible to slugs. The  Peruviana also has problems with spider mite and root diseases, which can be troublesome when it is grown under cold conditions.

Comments:

Aristolochia are spectacular flowering vines once they are established.  They are easy to grow even overwhelming as vining climbers.  Peruviana is the more challenging one to grow, having some inherent weakness to stem rots.
