dry air — Plant Disease

Stem necrosis is a condition characterized by the death of plant tissues on the stem, leading to browning, blackening, and eventual decay. It can weaken the plant, hinder nutrient and water transport, and in severe cases, lead to plant death. This condition can be caused by various pathogens, environmental stresses, or physical damage.

Your plant has reached the end of its life. This is not a disease — it is a terminal state, and it has already happened. What matters now is confirming the loss with certainty, understanding what went wrong, and deciding how to honor what remains: through composting, salvaging healthy cuttings, or simply giving yourself permission to start fresh.

Senescence is the natural aging process in plants — a genetically programmed developmental stage, not a disease. As a plant or its organs reach the end of their lifespan, cells undergo controlled breakdown, chlorophyll degrades, nutrients are recycled to actively growing parts, and tissues gradually decline. It affects leaves, flowers, fruits, and ultimately the whole plant. Senescence is a fundamental part of every plant's lifecycle and serves an ecological purpose: nutrient redistribution and reproduction. It cannot be reversed, but its progression can be slowed by attentive care.

The finished flowering period is a natural lifecycle stage — not a disease — that occurs when a plant's blooms complete their cycle and die back. Triggered by shortening day length, rising temperatures, exhausted energy reserves, or the plant's genetic programming, this phase signals the end of active flowering. Depending on the species, the plant may set seed, enter dormancy, or redirect energy toward root and foliage growth in preparation for the next bloom cycle. Understanding this stage allows gardeners to take targeted post-bloom care actions that extend plant health and maximize future flowering.
