Why are the leaves on my plant turning brown on the edges? Leaf tips turn brown when that lost water can't be replaced for some reason. Anything that inhibits roots from absorbing enough water — or supplying it to the plant fast enough — can lead to unsightly brown tips. This includes providing the plant with too much water, too little water or too much fertilizer.
Should I remove leaves with brown edges?
Should you cut off dying leaves? Yes. Remove brown and dying leaves from your house plants as soon as possible, but only if they're more than 50 percent damaged. Cutting off these leaves allows the remaining healthy foliage to receive more nutrients and improves the plant's appearance.
