Light:

Full sun, partial sun (southern, eastern or western exposure).

Temperature:

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

Humidity:

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

Watering:

Bring soil to a state of visual dryness between watering.

Fertilizer:

Go easy on the fertilizer: 1/2 tsp. of fertilizer per gallon of water every two weeks.  Discontinue feeding in fall and winter, resuming once growth starts in spring. 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 they need to be shaped.  The best time is just before growth starts in late winter or spring.

Insects and Disease:

Punicas can have problems with whitefly. aphids and mealy bugs.  A careful eye needs to be kept on plants that have summered outdoors as they can pick up insects when outside. Their root systems are strong and have little problems.

Comments:  

Punicas flower on the tips of the soft growth throughout the summer and are self-pollinating.  They are deciduous or semi-deciduous plants that can be grown cool and maintained under lower light during the dormant period.   P. granatum nana is an excellent container plant often used in bonsai culture.
