So, I had some trouble last year with this too. Several of my young plants are displaying unusual leaf growth. The leaves grow very narrow (sword-like). It can be described as "spindly" growth. There are no signs of bacterial/fungal problems. There is no black or yellow/brown spotting. The vigor is reduced, also. I have an idea what this is....not sure. What do you think? Sorry, I can't do pics (too old). Thanks in advance!
