Tango Mandarin suckers?
I got this Tango last year at Lowes.
I repotted it soon after I got it (soiless mix) and it seems to be doing ok. It had good growth this Spring and nice buds. A couple of decent sized "shoots" came off the graft area. I didn't think much about it until reading a question on the forum about suckers below graftline. The leaf on these "shoots" were very different from the leaves above the graftline. I pruned 3 of the 4 "suckers"...then ,as an afterthought, decided to post this with a picture.
I hope these were "suckers".
Any comment is helpful.
