fig lower leaves turning yellow/brown with black spots, falling
this is my first post- your online community is amazing!
i did find another thread where someone described lower leaves of their fig turning yellow and falling off and i did glean some info from this, but i want to make sure im not overlooking anything bc i have a bit of a mild obsession with my figs...
i have 4 figs, each in pots. zone 5, they get at least 7 hours of direct sunlight every day, and it has been hot hot HOT lately. i noticed about 2 weeks ago that my large brown turkey (potted in a large plastic muck bucket with several small makeshift drainage holes in the bottom) bottom leaves, maybe 3 or 4 of them, were yellowish and brown, especially at the tips, and there were a bunch of pinpoint black dots on these leaves as well. these have since fallen of and now im seeing 5 more with this issue. i have had maybe one or two similar leaves noted on 2 of my other fig trees. other than this the tree is growing like a weed. i just started to use dr earth fertilizer for flowering trees (rec by my garden center for the figs) after i noticed the leaf issue.
based on what i read in the other forum that sounded similar- it may be too much water, or the roots may be getting too hot. is this correct? is there anything else i should be doing? and im assuming the pinpoint black dots dont mean anything more than that the leaf is dying?
help would be hot, thank you guys so much!!
