Hi Stan,

I wonder if you can help me with some of my house plants. The leaves of some of them are turning brown at the edges and then they turn crisp and dark. It almost looks as if they were frozen, but that's not possible.

Thanks for your help.

Elaine - By the condition of your plants, it may be the excess content of manganese in the potting soil or the salts from water or natural salts from fertilizer.

Take a water sample to be tested for salt, or have the lab evaluate it for plant life.

Drench the soil the plants are potted in with distilled water. This leaching is accomplished by watering a gallon or two of the distilled through until it almost runs clear, or looks like weak tea, or is a lot lighter in color than the first application that comes through the holes in the pots bottom.

Not very scientific, but as I don't know the sizes of the pots or soil volume in the pots, it's good enough.
You could try watering with snow melt, at room temps, when the leeching is finished, until the plants respond to show new growth.

Hope all becomes well.
