Light:

Full sun or partial sun (a south, east or west window). They do benefit from a little direct sunlight.

Temperature:

Maintain indoor temperatures above 60° for potted plants.

Humidity:

They will tolerate low levels with no harm.

Watering:

Bring soil to a state of dryness between watering.   Do not keep them evenly moist.  When watering, thoroughly saturate soil until a little water runs out of the bottom of the pot.  Growing in clay pots will help maintain a healthy root system.

Fertilizer:

They are light feeders so 1/4 tsp. of fertilizer per gallon of water once a month is a general recommendation.  When growth actively stops in winter, discontinue feeding. 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:

Prune any time growth is excessive or after the flowering cycle is complete.  They bloom on the new growth, so hard pruning will slow down flowering.

Insects and Disease:

Stephanotis is highly susceptible to mealy bug.  Under damp soil conditions, they can have problems with root diseases. Growing them on the dry side eliminates the problem.

Comments:  

Stephanotis is a great indoor plant that thrives under moderate light and dry conditions.  Flower initiation is induced by environmental factors such as day length, light intensity, cooler night temperatures or temperature differential between day and night.  If it doesn’t flower, try increasing the light or grow cooler during the winter.
