Q. can philodendron withstand cold?

Live in Utah, gets cold. Can I leave outside for the winter?

A.

No, all philodendron species are tropical plants. While they will withstand a few hours of low 30's, even a touch of high 20's, in general they shouldn't be subjected to temps lower than 40F.

Q. frozen plants

My two house plants were accidentally left in the house when we were moving, and are both very limp, but still green. One is a philodendron, and the other is aloe hedgehog. I’m hoping to be able to save them?

Depending on how low the temperature went, and for how long, they may have suffered only leaf damage. If the roots weren't frozen, they'll be okay. Give them a few days to make sure the leaves that aren't damaged too badly can stand up, then cut off the damaged leaves and proceed as normal. If they can grow, they will. Just make sure the soil isn't staying too wet, as the plants won't have as many leaves as they had before to transpire water.

Q. split leaf philodendron

My split leaf philodendron grew fairly fast and looked very healthy last summer. Then in the fall, two lower leaves turned yellow, one by one, and the new leaf looked stunted and turned brown. I noticed white blister-like spots on the main stem,  upper area. The plant is growing yet another leaf; however, it is smaller than the others. What is bothering or even killing my lovely plant? This is a houseplant.

Yellowing and dieing of old and new leaves is possibly a sign of fungal infection in the roots, often called root rot, most likely caused by over-wet soil. A fungus would also account for whitish blisters on the stem. Philodendrons indoors, especially if they are in only moderate light, need to have the soil get almost dry all the way to the bottom of the pot between waterings. Probably what happened is that when the light level reduced as fall approached, you continued to water the same as you did in the summer. You need to reduce water when light gets less. Checking soil moisture with an electronic meter should be helpful. https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/testing-moisture-in-plants.htm

Q. My 5 year old philo has black knots on the stems

My 5 year old philodendron has black knots on the stems. Is this a disease? The plant has begun losing a lot of leaves.

Mine too! And its killing them all! Its some kind of virus or bacteria I am sure of it! Has yours progressed? Hopefully yours is just the lack of light or something simple like that

The dark knots on the stems where leaves branch off of our normal.

Is your plant getting enough light? If the plant is getting leggy, it is needing more sunlight.

Let your soil dry slightly between watering. Philodendrons respond pretty quickly to corrections in care.

Here is an article that has good information.

Q. yellowing split-leaf Philodendron

I have a split-leaf philodendron, which is at least 30 years old. It thrives on my sun porch in the summer and manages to survive in the winter (I’m in Massachusetts). It has developed blonde spots on a few leaves, and the leaf tissue appears to be dying. What should I do?

Yellowing leaves on philodendrons could be attributed to chlorosis, which is caused by a lack of magnesium in the soil. In this case, you would want to apply a balanced liquid foliage houseplant fertilizer that contains macro-nutrients. Yellowing in leaves can also indicate overwatering or too much direct sunlight.

Q. transplanting split leaf philodendron

My split leaf philodendron is so huge that it is taking over my patio. How can I transplant it? My plant is in an area about 10’x20′ and it is growing over the patio and has roots coming out all over consuming anything in its path.

Yes, you can successfully transplant your philodendron. You will need to be careful to get both the shallow aerial roots and much of the longer tap roots. The plant will need to be cut down, this will allow the roots to start growing in it's new home and not have to support the entire plant.
