Hi Fitdog,
Yep i have grown my curry leaf tree from a small plant that i got from "The Citrus Centre" (google) im in surrey, its now 3 years old and a healthy 2ft high bushy tree, last year i got a crop of berries that didn't quite make it to seeds, maybe this year lol,
just avoid frost, keep it away from ponds, (scale insect) and during the winter an outside shed is fine, during the summer feed with citrus food, soak the pot and then let it dry out before watering again, ie stick your fingers in the soil and only water when the soil is dry for at least two inches, its good fun, enjoy
