If you have a tropical climate (70 degrees average) and want to grow a coffee plant, keep the plant down to six feet tall to get the best yield and to make it easier to harvest. "Rainfall should be plentiful and the weather should switch between heavy rainfall and sunshine to bring the berries to full maturity" (source: www.thegardenhelper.com)
According to most sources, coffee plants don't care what the soil is like as long as there is not standing water. Without excellent drainage, the coffee plants will not flourish.
Recommendation from www.thegardenhelper.com:
Coffee plants are fairly easy to grow in the home as a potted specimen, but they should be moved outdoors for the summer if possible. They grow best in filtered sunlight, with night temperatures in the lower to mid 60s and day temperatures of 70F or higher. Plant them in any good commercial, fast draining potting soil . The soil should be kept on the moist side, but never soggy.
Coffee plants will produce fruit without any fertilizing whatsoever, but for best results and maximum yield, they should be fed every 2 weeks from March to October, and then monthly from November through February. Use a soluble, all purpose (10-10-10) fertilizer.
