new leaves on fiddleleaf fig has clusters of small red dots

patchesnbrownieOctober 13, 2009

Hello!

I had recently posted a question on this forum regarding my fiddleleaf fig tree and it was diagnosed as a general transplant shock. I had another question. The tree seems to be doing better (phew!) and sprouting out new leaves everywhere! BUT. The new leaves have clusters of these little rusty colored dots. They are shiny and just in the leaves (can be seen from front and back) but is NOT fuzzy or fungus-y. So I don't think it's rust. These dots are mostly just in the newest leaves...

Should I be concerned? What is going on??

THANK YOU SO MUCH! :)

I did some research because I think I'm having the same problem. I believe the problem may be under watering. Here's what I found at http://mrec.ifas.ufl.edu/foliage/folnotes/ficus.htm:

"Excessive moisture stress

Symptoms -
Small reddish spots, 1-3mm across, on the undersides of leaves of F. lyrata. The symptom is usually observed on stock plants in full sun which have been air layered, and most frequently during the driest months of December through June. This condition is rare on plants grown in shade. Leaves on wilted layers or cuttings of F. elastica, and possibly some other species, remain in relaxed orientation after normal moisture content is restored. This is a permanent condition. Branches of trees in an active state of growth may bend under moisture stress, then partially recover, leaving a permanent kink or "dogleg" in the stem.
Control -
Severe moisture stress can usually be avoided through good nursery practices. Leaf spotting can be prevented by timely irrigation of stock and use of the vertical slit technique of air layering versus the girdling procedure. Permanent petiole wilt and stem kinking can be avoided with adequate soil moisture and high humidity during propagation.

Prevention of excessive root development outside the container eliminates most of the shock that occurs when large segments of root are severed from plants because roots extend into soil below the pot. Use of plastic ground covers, drip irrigation and root pruning during production usually eliminates root pruning shock when plants are removed."
It could be something else, but I'm gonna try to water more and see what happens.
