Stem Rot
Stem rot is a serious condition where the stem tissue decays, often starting at the soil line. It requires immediate intervention.
Kemungkinan Penyebab
Overwatering and Poor Drainage
Why: Constantly wet conditions promote fungal and bacterial pathogens that attack stem tissue.
Signs to check: Stem is dark and soft at the base, may be constricted at the soil line, soil stays wet.
Fungal Pathogens (Fusarium, Pythium)
Why: These soil-borne fungi attack weakened roots and stems, especially in wet, poorly drained conditions.
Signs to check: Stem darkens from the base upward, tissue may appear water-soaked, plant wilts despite moist soil.
Physical Damage
Why: Wounds on the stem can allow pathogens to enter and cause rot.
Signs to check: Rot originates from a specific wound or damaged area on the stem, localized infection.
Apa yang Perlu Diperiksa
- 1Inspect the stem at and below the soil line for soft, dark tissue
- 2Check if the rot is progressing upward from the base
- 3Assess soil moisture and drainage conditions
- 4Look for any wounds or damage that could be an entry point
Langkah Selanjutnya
- Cut the stem well above the rotted area with a sterile blade
- If healthy tissue remains above the rot, try rooting it as a cutting
- Discard all affected soil and sterilize the pot before reuse
- Repot surviving portions in fresh, well-draining mix
- Drastically reduce watering and ensure excellent drainage going forward
Kapan Harus Mencari Bantuan
- Rot has reached the main growing point or crown
- Entire stem is soft — propagation may not be possible
- Other plants in the same area are showing similar symptoms
Poin Penting
Stem rot is often fatal if not caught early. Act quickly to save healthy tissue and correct the wet conditions that caused it.
