Hi all .I have a old empera mandarin(approx 20 years).I have never had any problem with her.Untill last year she threw out thousands of under average size fruit,i probably should have culled a few hundred but didnt.Anyway this year there is no fruit at all,and she dosent look very well,leaves all yellowing.Do manderins skip fruiting years?I dont know,anyway if anyone got any imput would be greatly appreciated.
