BIG leaves.... water or fertilizer?
What have you determined will make big leaves on "leaf only" plants, water or fertilizer? I have a selloum philodendron in the ground and the leaves are only 5" long although when I bought it several years ago, it had huge leaves three times that size. I've given it liquid fertilizer a few times this year, it gets plenty of water. Am I not giving it enough fertilizer? Also, my hydrangia is the same... small leaves and it never did get very big this year. I'm stumped.
