Heartleaf Philodendron--how to get larger leaves?
I have a question about heartleaf philondendron. I have two cultivars, Brasil and Lemon-Lime or Neon (or whatever they call the chartreuse colored one these days, I've seen lots of different names out there). On both plants, but especially the Neon, the new growth comes in much smaller than the original growth. Both plants are in nice bright eastern exposures, in a very well-lit porch/plant room. The growth is dense and pretty, and the plants look nice overall, I just am wondering what I can do to get bigger leaves. I am thinking of using a trellis and getting them to climb--would that help? I never have this problem with my Pothos, but with the Philodendron it keeps happening....
Thanks for any information you can give!
