Why is my Boston Fern Turning Brown?

Why is the inner part and the tips of the fronds of my Boston Fern turning brown.

Hi Liz,

The brown fronds on your Boston Fern could be 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 fertilizerPlants need fertilizer only when they are actively growing. Slow growing plants in low light require very little plant food. Too much fertilizer is worse than not enough. Most plants prefer a water soluble plant food at 1/2 the recommended strength. Plants that are in bloom or dormant should not be fertilized. Houseplant food contains nitrogen (N), phosphorus (P), and potassium (K). A fertilizer containing these elements in equal proportion is considered a balanced plant food. Nitrogen helps in photosynthesis and encourages the growth of leaves and stems. Potassium and phosphorus also help in photosynthesis and aid in root and flower development. Most fertilizers have trace elements of other minerals that are lacking in the soil but are necessary for good plant growth. Fertilizers have a high salt content. If a plant is not producing new leaves and doesn’t absorb the fertilizer, salts build up in the soil. These salts can burn the roots, discolor the leaves, and cause new growth to be small..

Dilute the plant food to 1/4 to 1/2 the recommended strength to prevent the ends of the fronds (leaves) from burning.
