Oron, as you seem to very knowledgeable about ficus, could you tell which specimens these two in the photos are? And about the aerial roots: I see that many people cut the aerial roots as they don't like them hanging down, but isn't that bad for the tree? I had to cut some of them off, as the ficus keeps growing long branches down and in the inside and builds then messy clumps with aerial roots and if I don't cut them off, the mealy bugs can take over. I have had good results by pruning back all the branches inside in order to get air in the tree and spraying with neem oil. Also covering the roots with weed membrane and stone chippings keeps the moisture better in the soil and the leaves are more fleshy and darker green. Watering regularly seems to be important, otherwise the leaves begin to drop.
