🔍 Possible Causes (5)
Aphids
Aphids are small, soft-bodied, pear-shaped insects (1/16 to 1/8 inch long) that feed by sucking nutrient-rich sap from plants. They reproduce rapidly and can quickly weaken plants, causing distorted growth and transmitting plant viruses. Aphids come in various colors including green, black, red, yellow, brown, and gray. They secrete honeydew, a sticky substance that attracts ants and encourages sooty mold growth.

- • Clusters of soft-bodied insects in various colors (green, black, red, yellow)
- • Curled, distorted, or yellowing leaves

Heat Stress
Heat stress occurs when plants are exposed to excessively high temperatures, typically above 85-90°F (29-32°C), causing physiological damage and compromising vital processes such as photosynthesis and transpiration.
✓ Related symptoms:
- • Yellowing of stems, fruit, or bark

Sunburn (Sun Scorch)
Sunburn or sun scorch is an environmental condition that occurs when plants are exposed to intense, direct sunlight beyond their tolerance level. This causes the breakdown of chlorophyll in the leaves, resulting in bleached, dried, and damaged foliage. The damage can happen rapidly, sometimes within just a few hours of exposure.

- • Affected areas turn yellow, then brown, and become brittle

Crown Rot
Crown rot is a serious fungal disease that attacks the crown (base) of the plant where the stem meets the soil. It is caused by various fungal pathogens including Phytophthora, Fusarium, and Rhizoctonia. The disease thrives in waterlogged conditions and can quickly spread to kill the entire plant if not addressed promptly.
✓ Related symptoms:
- • Yellowing of lower leaves that drop prematurely
⚡ Quick Fixes:
Immediate unpotting
Underwatering
Underwatering or drought stress is a physiological disorder that occurs when the amount of water a plant loses through transpiration exceeds the amount its roots can absorb from the soil. This leads to cellular dehydration and various visible symptoms that can compromise plant health and productivity.
✓ Related symptoms:
- • Yellowing leaves, especially older ones (chlorosis)
