The pothos I grow are all indoors, in water gel beads, and they thrive quite well, and I have not given them any fertilizer of any sort. I notice they just like bright light but not direct light, it seems to burn them. I have decided to use water gel beads so it does not stink and it gives the roots a chance to breathe.
Be very careful with Dengue..it so lethal in the Philippines, and with our frequent rains and high humidity there, it is mosquito breeding heaven. I was just so glad I did not get it during my 2-month visit, with all the mosquito bites I get everywhere. Maybe plant citronella plant around as well...
