Split Leaf Philodendron

I have two large split leaf philodendrons that are about 5 years old and have been very healthy, but the foliage froze in our bad freeze this year (Austin, TX). I have pulled the stems from the main stalk, which feels like it is waterlogged in about the top third of the stalk. The stalk is about 5 inches in diameter at the base. Should I cut these back at the ‘drier’ point or leave them alone? Do you think they survived, or should I replace them?

Any part of the stem that feels "mushy" is dead and does need to be pruned. Stems that are still firm will regrow leaves. And it will regrow if the roots survived. These articles will help you as well:

Disease on House Plants

I have a Philodendron and two tropical plants that were in my kitchen bay window.  I noticed a white powdery material on the leaves of the plants that were together, not on the ones separated. The powder was on the top and bottom of the leaves but was easily removed when wiped with a damp cloth. What could this be?

Neem oil will work well on powdery mildew problems. You can read more about this oil here: http://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm

Odor Coming From Inside Stem

I have 2 houseplants, one is a new log or totem pole and the other is a philodendron. When I water sometimes, I pour some down into their stem, but lately there is foul odor like wet laundry that has set for weeks. It’s a bad smell, only on those 2 plants. HELP. They still look good and healthy, their shoots just stink.

It sounds like the plants may have root rot and what you smell is the roots decomposing. There is not much that can be done to help the plants, but this article may help: http://www.gardeningknowhow.com/plant-problems/disease/treating-root-rot-gardening-tips-for-housplants.htm

They over watered it and this is what caused the root rot.

Philodendron Disease

My Philodendron has been a healthy plant and grown a lot over the last year. Currently I have what appears to look like dry grass on the top and underside of some of the leaves. Any idea what might be causing this and what it is?

ANSWERS

They are likely aerial roots. I would recommend providing something for these roots to cling to, like a pole of some kind.

I Have a Beautiful Philodendron That Is More Than 15 Years Old

I have taken several starts from it and it still thrives. Lately I’ve noticed the ends of the leaves are fraying. I only noticed this because it’s never happened before. I’ve also noticed small brown circles, like an insect’s been munching on it. As of late, my plant doesn’t seem to be doing too well. Please help.

Also (thought of this after I answered)....repot the plant but before you do, wash all old soil off the roots. My friend had a spathephillum (Peace lily) that was barely growing. The problem was in the soil: the vermiculite had gathered at the roots, preventing the plant from growing. Once removed, washed and repotted, the 'spath' began growing and is now a very impressive specimen.

It sounds like your philondedron is exhausted. Try rooting cuttings in water and create a new plant. I know that sounds painful but sometimes it is just the only thing to do.
