I have been so happy about this new leaf on my Schefflera tree! It is the very first leaf to grow since I got the plant back in March, and it means that the plant has recovered from an infestation of mites that my daughter and I worked hard to cure it from, schlepping the tree (it's about six feet tall!) to the shower where we doused it with insecticide soap. We had to do that procedure three times until we felt we had finally gotten rid of the pests.
I also moved the tree to a slightly sunnier spot in the same room and then, eventually, it stopped losing leaves and slowly perked up. Now it has recovered enough to sprout a new leaf, and even if it still has some brown leaves from its illness, it is on the mend.
