Hi. I have a 8" stem cutting from a Philodendron pedatum that I have been nurturing for an entire year now. It did root, and I have it planted fairly deeply in a 6" pot with about half of the stem submerged in a good quality loam. I am careful not to ovwerwater.

The growth on this rooted cutting is so slow! I examined the root system this summer and it has about a golf ball size mass of roots and three tiny leaves. I do realize it is overpotted, but that doesn't seem to account for its small size. I gave it some highlly diluted food and put it in diffused light to bright shade outdoors all summer.

I am in Fresno, where the temperatures can reach 110 DRY degrees. I know this plant requires humidity, but it doesn't seem to suffer browning on the leaves...just SLOW, SLOW growth.

Any hints?
