I have tried to grow tropical, semi-tropical, and desert trees here in Chicago for 10 years or so with this experience: I can keep almost anything alive, get most things to bloom and set fruit, and get few-to-no nuts/fruit to harvest. Lately I've tried mango, papaya, pomegranate. My olive tree set many fruit last year that didn't make much progress.

You can decide if that is a challenge or a description of futility. Citrus does fine if you want something exotic.

I tried macadamias and pistachios a way back. Got a macadamia seedling or two from eBay; started the pistachios from seed (first seeds I started in the refrigerator as I recall). Squirrels ate them all the first time I put them outside--I was disappointed I hadn't seen that coming. The last few years I've built cages out of hardware cloth for my avocado seedlings; they worked. Now that you posted this note, I may try macadamias again. Me and Charlie Brown running up to the football--always hopeful.

Good luck. Keep us posted.
