Light:

Full sun (southern exposure).

Temperature:

As a potted plant, maintain indoor temperatures above 40°.

Humidity:

Maintain a 50% or higher; however, they will tolerate low levels with no harm.

Watering:

Bring soil to a state of visual dryness between waterings.  When watering, thoroughly saturate soil until a little water runs out of the bottom of the pot.  Under high heat and sun they use copious amounts of water.

Fertilizer:

They are moderate to heavy feeders so 1/2 tsp./gallon once a week is a general recommendation or ¼ tsp/gallon at every watering throughout the growing season.  When growth slows 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:

Generally they are pruned in the fall as the flowers wane and again in late winter if growth is excessive.  However, they can be pruned at any time of the year to control size but it will also disrupt flowering.

Insects and Disease:

They have susceptibility to whitefly and spider mite and few problems with diseases.

Comments:

Angelonias are fast and easy to grow, bringing months of continuous bloom to the garden and potted container. They do require lots of direct sunlight and as soon as the light levels drop they go out of flower.
