You'll find some really good repotting directions & tips if you follow the link below ..... and there will be a lot of other info applicable to tending your plant in a container. A true repotting will allow the tree to resume growing closer to how it wants to grow. IOW, you'll be eliminating a condition that is probably seriously limiting growth and vitality. Most people think its a "growth spurt", and would call it such, but what you'll be seeing is how limited the plant was, and how well it might have been growing if roots had room to run a little. That's not being critical of you - just using your situation as a convenient way to offer some perspective on those "growth spurts". ;-) Al

Holy socks! What a success you've had!!! First--Thank you so much for replying to my post and question. Your plant, 14 years ago, is exactly like what we are dealing with, though you had a lot more foliage than we do. Our plant sits in the corner of a "greenhouse" attached to our house--not a traditional greenhouse, though, more like a solarium but that sounds much more posh than what we have. It does have lots of windows on one side and two skylights. The "stalk" of the plant keeps creeping sideways and we've tried turning it--to no avail. I've found out it is just a creeping type. The link you included is super helpful. I see that what I found online about the creeping nature may not be exact. Looks like that stalk could go relatively straight up given best environment. I don't think we have sufficient 360° lighting. Your success in repotting gives me so much encouragement to proceed! We've had this plant for over 30 years; it has moved with us at least five times--across three or four state lines. We can't remember when we acquired the plant, it's been so long. We've been lax in repotting it in the last 10-15 years, as it always seemed happy--well, overly crowded for the last 5 years. But now it is just leaning too far out of the pot. I doubt there's adaquate soil in the pot for the roots to thrive. [I planted spider plants in it this pot to give a bit of color around the base. BAD idea; now I know. Those spider tubers fill up the pot, using all the root space.] I have some questions about your process which I'll save for the end of this post, so you can find them easily, if you have time to reply. I've found two suggestions online eslewhere. One is to repot it into an horizaontal/rectangular pot toward one end so it can be happy creepy and sending roots down as it creeps across. The stalk is at least 3" diameter at this point and over a foot long, with many air roots or whatever they are. We have a rectangular recycling big that we no longer use and that may be the new pot, but I fear it is too large and dampness could be problem. The second suggestions is to put another pot next to the plant and let the stalk grow and creep toward the 2nd pot, rooting as it moves in. Once it's established in the new pot, the stalk is severed so that the "baby" shoots are left behind in the old pot and the creeping stalk starts anew in the other pot. We have a large pot we could use for this purpose (and perhaps the recycle bin could work, as well). The problem with #2 solution is having enough space to allow this progressive growth to take place. Plus, your statement "the bigger the pot, the bigger the plant" serves as good advise for us moving forward. Pretty soon it'll need it's own room! My questions: 1. I'm not sure what you mean by "Mostly now I take offshoots with no trunk..." Ours has some "knees," I'll call them that have popped up and baby leaves shoot up there. I that an offshoot? 2. When you repotted it the first time, you planted the whole trunk, half way, and that worked. Did you cut it off or section it in anyway? 3. And related to #3 did it begin leaning or creeping again after you repotted it? 4. What are your thoughts on the two suggestions I found on line? Your photos are great and very helpful. Thank you for including those. We live in Missouri, and we could put the plant outside spring thru autumn but it's too heavy to move, so we don't. We can't plant it outside in the garden because we do get a solid winter. Now, as winter approaches we are trying to get it repotted so we can work in what's left of the warm weather outside because I think this is going to get messy. And all the other plants are coming into the greenhouse for the winter so this guy has got to take up less space rather than more. I apologize for the length of this post, but I'm just so excited to have someone who has experience with this give guidance. And I am so grateful for your reply. And I welcome advise from anyone else reading this (Ken_Adrian :-) in case you have any ideas for our Philodendron bipinnatifidum future. Best regards, --deborah

In my opinion Bloody Mary is an illegitimate name, it is actually Majesty which is a very old hybrid. Some wholesaler probably had thousands to sell but didn't know the name, so made one up. I've been growing Majesty for decades and "Bloody Mary" for a few years, there is no difference between the two. Leland Laren, Jay is correct... I agree that your specimen is Pink Princess that's lost its variegation. Note the pink stripes along petiole edges, this is typical of Pink Princess and would not occur on any other philo, especially a non-variegated one. If you haven't done it already, it would be interesting if you would take cuttings from your plant to see if latent nodes along the stems would produce new plants with variegation. Cuttings near the base, or the base itself, would be most likely to produce variegation. Of course that means butchering your plant more than you might like. I have many, many plants of Pink Princess, including large ones in 3 gallon pots. My experience is that in general, the bigger they grow, the less variegation they have. Among new offsets from propagated plants, I often get one or two with no variegation. Interestingly, I see no difference whatsoever between these unvariegated plants and an old, vintage philodendron called Royal Queen. So I think Pink Princess is a sport from Royal Queen, perhaps occurring 80 to 100 years ago. Please post results if you've propagated your plant already, or might consider it this spring or summer.

Pinch the growing tip to force it to send out more vines. Or wrap the vine back on itself tacking some of the nodes to blank areas of the soil. After a few years you will be cutting off excess vines to give away or throw on the compost heap. Take care of it and it will be everywhere. https://philodendronplant.com/heartleaf-philodendron-grow-and-care-tips/
