Should I Cut Yellow Fan Leaves of a Cannabis Plant as It Finishes Flowering?
As your cannabis plant approaches the end of its flowering cycle, you may notice that the large, fan-shaped leaves begin to turn yellow. This is a natural process as the plant redirects its energy from leaf production to flower and seed development. However, some growers wonder if they should remove these yellowing leaves.
There are several benefits to removing yellow fan leaves during the late flowering stage:
- Improved airflow and light penetration: Yellowing leaves can block airflow and prevent light from reaching the lower branches of the plant, which can lead to reduced yield and mold growth.
- Increased nutrient availability: As yellow leaves die, they release nutrients back into the soil, which can be taken up by the developing flowers and buds.
- Reduced risk of pests and diseases: Yellowing leaves are more susceptible to pests and diseases, which can spread to the rest of the plant if not removed.
However, it's important to avoid removing too many yellow leaves, as this can stress the plant and reduce its yield. Remove only the leaves that are significantly yellowed and have started to wilt.
