In that case, coffee could live outside most of the year. I have a tunnel greenhouse frame that is on my someday list to get set up. I could have coffee plants!
What beautiful leaves!I thought I would share my experience with growing a coffee plant in case anyone is growing, or intends to grow, a plant. The plant was tiny when I got it, but a very nice healthy green. After several weeks the leaves began to turn yellow and pale. No amount of fertilizer would solve the problem, so I tried adding iron, with no improvement. As a last resort, I added acid and the plant showed some improvement. Then, I added a lot more acid and the plant took off. I thought they needed shady conditions, however, when I placed it in the greenhouse recently I gave it full sun. The plant has responded by increasing the size of its leaves tremendously. When I bring it indoors for the winter I intend to place it under a LED grow light in warm conditions.

Coffee prefers a temperature from 60 to 75F and is very sensitive to cold and frost, with the latter destroying both leaves and fruit. That said, it was outdoors all summer and the temperature varied way beyond that range. Presently it is in the greenhouse chilling with the olives, with the temperature in the 40s. I did notice a bottom leaf that does not look happy, so I think I will move it indoors soon. The olives can take temperatures to about 28 F or so, but I don't like the temperature to get that low. I hold off on the heat for as long as possible.
