I'm in Los Angeles, and I had two miracle fruit plants for about a year. One that I bought locally is doing great, the mail-order one (I got from mail order, the site is banned here) is not growing as fast, but looks fine.

I overwinter inside the house. In the nursery they overwinter miracle fruit in the greenhouse. In summer keep the plant outside in a slightly shaded and protected spot as its leaves get damaged by strong wind. Keep well-mulched (I mulch with its own leaves) and deeply water about once a week or when the soil begins to dry up. Fertilizer is needed only occasionally to supplement iron. Repot in a Kellog potting mix (not Miracle Grow, as it is too strong). Nothing special is needed for humidity.

Miracle Fruit does not like when its roots are disturbed. I lost one plant to repotting when I removed too much soil. So be very careful when repotting, and repot only when absolutely needed.

Thanks for the info. I was really hoping to learn from someone from our area (NorCal) to share experience growing it here (San Fran, quite different weather than SoCal). Disappointed to see no response here from any potential growers in NorCal area.

btw, I follow MF growing guidelines put out on Logee's (search their website for Miracle Fruit and select Plant Care tab toward the bottom of the web page for excellent information).

I think those die easily during the winter without shelter. I had a couple that died as soon as it hits winter.
