Light:

Full sun (a south exposure).

Temperature:

As a potted plant, maintain indoor temperatures above 50°.

Humidity:

Preferably 50% or higher; however, they will tolerate low levels for short periods 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.

Fertilizer:

They are moderate feeders so 1/2 tsp./gallon twice 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:

Plants can be pruned at any time; however, it’s best to prune in late winter before growth starts so as not to disrupt flowering.

Insects and Disease:

Spondias have few problems with insects. They can have problems with root disease when grown too wet and cold in the winter when dormant.

Comments:  

Spondias are easy to grow and fruit when grown in full sunlight.  They can almost fruit themselves to death and start fruiting as young plants.  It is best to discourage heavy fruiting until they have reached some size.  Be careful not to keep too wet in the winter when they can be deciduous.
