My poor plant is covered in what appears to be some sort of "rust", and upon further inspection I found a bit of honeydew. I sprayed the philodendron down with Brand X, both above and underside, but now I am wondering if perhaps the condition is caused by something else. Any ideas???

Hi Marajane,

I don't know what is "rusting" your plant but the shiny leaves remind me my plants are way overdue for a Brand X cleaning. Thanks for the reminder! [Smile]

It looks like sunburn to me. Rust would rub off. Does it rub off?

did you maybe get water on the leaves and have it put in direct sunlight? sometimes if you get water on the leaves,etc of a plant and the plant is in direct sunlight, the water will act like a mirror reflecting the sunlight and it will burn the leaves therefore giving the plant rusty looking spots on the leaves. sorry I couldn't help much!

Thanks for all the suggestions. I suppose it is possible that it is sunburn (blame is on dh for watering the plant outside), but for some reason I thought the "rust", burns, what have you, were growing. Will wait and see!

Just a thught, but sometimes salts build up in potted plant soil. See if the soil surface has a bit of whitish stuff on it. Submerge the whole pot in the sink or a bucket and let it saturate completely, then drain. This will leach out excess salts. Then cut back on fertilizing.

I use a foliar fertilizer spray on some of my plants that want it, and one day I squirted my big philodendron that looks a lot like yours. BAD idea! It's now got brown spots on its leaves where ever the fertilizer-water hit. Any chance anything like that could have happened to yours?

may God bless the WHOLE world!

I don't think so, as I do not use fertilizer. But thanks for the suggestions!

I endorse the sunburn theory. Keep DH away from it and it should not be a problem in the future.

The stickiness is probably a natural sap secretion that this Philo often produces.
