I can tell you that the Suger Belle grows fast like a weed. Fastest growing citrus tree I've ever seen. I am about to buy another one to replace the one I ruined when I planted it (long story). That one, when I got it was a tiny twig with only a few leaves. Before I could get it in the ground it had grown half a dozen branches and the foliage was a foot in diameter. 3 weeks time for this.
For those who have them in the ground and not covered with citrus screening to keep out the HLB bug, are you not seeing any sign of greening at all? If so I think I'll keep the new one I plan to buy out in the open. It's much easier to care for, and I won't have to see that unsightly screening poking up out of my yard.
