Why is my Boston Fern Turning Brown?
Why is the inner part and the tips of the fronds of my Boston Fern turning brown.
Brown fronds on your Boston fern are usually the result of over-watering. Allow the top 30% of the soil of a Boston Fern to dry-out before watering the plant. The fronds or leaves may even turn a pale green which indicates the fern needs water. Watering with “hard water” causes white marks to appear on the leaves of a Boston fern. A Boston fern is more drought-resistant than most ferns so when in doubt, don’t water.
Brown tips on the fronds are caused by too much fertilizer. Feed a Boston fern monthly with a balanced liquid fertilizer when the plant is actively growing. Dilute the plant food to 1/4 to 1/2 the recommended strength to prevent the ends of the fronds (leaves) from burning.
