Gnappi,
thanks for posting about the tree u got from me...it was one of the prettiest ones I had in that size.
should fruit (or flower at least) next year.
I have plenty of Grimals now...but price is high because of demand! Small trees are at least $25, the are less than 12 inch tall, but are over a year old (they should have been repotted a while ago, so they stayed a bit small, but I recently repotted them, and they have started to grow quickly)
this season my trees made the most Grimals ever (they've only been bearing for a few years)...i was eating them a bit too early at first, because I was so excited to taste them....but as the season progressed, I got to taste some that were ripened properly...they really have to sit on the tree for a long time after achieving full coloration...I also like to restrict watering, (maybe reducing the amount, or letting the leaves slightly wilt)...i believe this can hasten the ripening process, and increases the sweetness of the fruits!
when you squeeze them, they should feel like a partially deflated basket ball, then they are ready to be harvested.
