Peace Lily #438690

Asked January 24, 2018, 7:30 AM EST

I have a peace lily that was given to me for my brother's funeral 10 months ago. I'm assuming it's root bound. When and how can I transplant it? Also, I have enclosed images of the leaves. What is the problem and how can I remedy it? Thank you in advance. Cathy

Expert Response

My sincere condolences for your brother's passing.

Why do you think it is pot-bound and needs re-potting?

The peace lily may have cold damage. Has it been exposed to cold drafts (from doors, windows, transporting it, etc.)? Is the damage on one side of the plant or across the plant as a whole?

Peace lilies will also turn black from too much water. Make sure the pot it is planted in drains well, and don't let the plant sit in water. A plant that has consistently wet soil will contract root rot (roots are literally rotting away) which will ultimately kill the plant.

Feel the soil before watering to determine if it needs watering. If the top 2 inches are dry, water with distilled water, reverse osmosis water or untreated well water. Do not use city water as fluoride is toxic to peace lilies. Add an all-purpose houseplant fertilizer at half the recommended strength to the water when you water.
