What to do if Boston fern leaves turn yellow

Unsuitable soil

When growing Boston fern, it needs loose, fertile and well-drained lime or sandy soil. When choosing the soil, pay attention to its growth needs. If the soil used does not meet the growth needs of the Boston fern, it will cause it to grow poorly, with leaves turning yellow and falling off.

When growing Boston ferns in potted plants, you can use a mixture of garden soil, river sand and leaf mold.

Direct sunlight

Most ferns are shade-loving plants, and the Boston fern is no exception. When growing Boston ferns, although sufficient light is needed, be careful not to have strong direct sunlight, otherwise it will easily cause the edges of the Boston ferns' leaves to burn and turn yellow.

When growing Boston ferns, if there is strong sunlight outdoors, it is necessary to provide shade in time. When growing indoors, the Boston fern can be placed on the east or north windowsill for maintenance.

Insufficient watering

When growing Boston ferns, you need to water them sufficiently because they like a humid environment. Therefore, you also need to maintain a high air humidity so that the leaves of the Boston ferns can remain green. However, if there is insufficient watering or the air is too dry during maintenance, the Boston fern will turn yellow or have burnt edges. When growing Boston ferns, make sure to water them sufficiently. When they are growing vigorously, you need to spray water on the leaves every day.

Improper fertilization

Improper fertilization mainly refers to applying too much fertilizer or contaminating the leaves when applying fertilizer, which will cause the leaves of Boston fern to turn yellow. When fertilizing the Boston fern, generally apply a thin layer of fertilizer water once every half a month, and pay attention to the cleanliness of the leaves.

Improper pruning

If the Boston fern is not pruned in time during maintenance, the branches and leaves may become messy and crowded, and too dense branches and leaves are not conducive to the growth of the Boston fern. Therefore, pruning is very important in daily maintenance. If you find any dead leaves, you should cut them off in time, which will also be conducive to the sprouting of new leaves. The old leaves should also be properly pruned in autumn every year to avoid too many branches and leaves, which will cause the plant to grow weak and turn yellow.
