In November, many indoor plant owners notice that a Ficus that looked healthy all year begins to turn yellow and lose leaves. According to Iowa State University, in autumn plants receive less sunlight, which slows down growth and causes some of the older leaves to die off. This is a natural process, but sometimes yellowing becomes a sign of improper care that is important to recognize in time so as not to lose the canopy.
Why Ficus reacts to seasonal changes
Benjamin's fig (Ficus benjamina) is especially sensitive to autumn changes. Experts from Pacific Northwest Extension explain that in late autumn it may drop even green leaves, and sometimes loses a significant part of its canopy while remaining alive and capable of recovery. The plant reacts not only to the shortening of daylight hours, but also to dry air from heating appliances, cold drafts, and moving the pot. According to Styler (RBC-Ukraine), it is the combination of these factors that most often triggers leaf fall in October and November.
Seasonal leaf fall or a sign of disease
Yellowing leaves are not always season-related. Other possible causes include excess moisture in the soil, over-fertilization, sharp temperature drops, and a lack of light. The Royal Horticultural Society (RHS) recommends providing Ficus plants with adequate lighting, moderate watering, and stable temperatures to eliminate stress conditions. If the branches remain alive, the soil dries out normally, and the leaf drop gradually slows down, the plant is most likely simply adapting to winter conditions.
What to do and what not to do
Recommendations from the University of Wisconsin note that after winter leaf drop, the first step should be to improve maintenance conditions rather than rushing to prune bare branches. It is recommended to remove only dead shoots. Fertilizing is also best postponed until active growth resumes, because fertilizers do not fix a lack of light or the consequences of improper watering. Routine repopting is usually done in spring, not in response to a few yellowed leaves.
When to worry
A serious reason to check the condition of the roots is a situation where the soil remains wet for a long time and the stem softens. In this case, the plant must be inspected for rot. In all other cases, when the canopy recovers and new growth points appear, Ficus successfully survives the cold season without intervention. The key recommendation from experts is to monitor the dynamics rather than reacting to isolated yellowed leaves with emergency measures.
