Wood, if you Google, Philodendron pictures or Philodendron photos, several pages of Philo pics pop up. They are sooo very beautiful! Your Philo sounds gorgeous..too bad you don't have a pic to share. Gotta love variegated plants! :) Do you know Randy and Sherm? They specialize in variegated plants..Father and son..They're not sellers/businessmen, collecting, hunting variegated specimens are their hobby. They even found variegated 'weeds' and 'Petunias.' lol. Think I have their site addy on Favorites, I'll check. He had a good selection of variegated Philos... Last I heard, Randy lost interest, or something happened, so he gave or possibly sold his plants. But his site is still avialable. Ill check and get back to you. I assume Philos need the same care. Perhaps, yours needs more light to keep colors pronounced.?.? Bright light, and definately humidity...they love humidity. My Philos do well in obstructed south windows, year round. Windows don't get much direct sun, mostly bright light. I keep a humidifer in the room, and spray daily. Smaller pots sit on pebbles with water, and a weekly hose in the kitchen sink. I had a huge Philo collection, but gave most to a friend..When older they need a LOT of room, something I'm running out. lol.. My Pink Princess, (green/red/pink) are in a cool room, a few feet from west and north windows. An indoor fountain runs 24/7, so it/they're (have two) get humidity and a fair amount of light..One PP is a little over 4 yrs..Although it's kept its colors, leaves aren't as large as they should be..So, IMO, variegated plants needs quite a bit more light than non-variegated.. Try Googling, and see if you come up with a match. I'll look for Randy and Sherms site addy..Toni

Hi, Most self-header Philodendrons are in the subgenus Meconostigma, and P. giganteum is not in there, so I would think that it is not a self header. Here are the meconostigma philodendrons: Here is a link that might be useful: Meconostigma Philodendrons

I am no philo pro but it looks like one I saw on Ebay called Philodendron giganteum.

you confuse me ... you do not mean you are potting in bone dry media .. are you??? there could be a big difference in water to wet media ... as compared to watering to settle the media in the pot ... i always pre moisten my media before potting ... then a little sip to settle it all in .... and for sure.. i hope you arent using soil .... and not all medias are created equal ... what media are you repotting with .... and how big is the new pot.. if you suspect you jammed it into a little pot last time??? the fact that you suspect your winter house should suck the life out of the media.. seems to suggest that you media is failing in its only job.. water management ... in winter.. in the great white north... you ought to have leaves edges browning.. from lack of water and humidity.. not roots rotting off when watering once in a blue moon ... in other words.. i think you need better media .. a redo with the same stuff.. might not get you anywhere ... ken
