Q.Why Hasnt My Birds Nest Fern Gotten Any New Leaves In Over Two Years.
It still has green fronds and some brown edges, but it hasn’t gotten any new growth for a long time. Is it dead? Can I stimulate it to get new leaves?

If this isn't fed throughout the year, then this is likely the issue. I recommend feeding with a half strength liquid orchid feed two or three times per year. Feeding at full strength is not ideal, so be sure to cut the recipe from the instructions in half when mixing into you water.
