Frost Damage
🔎 按症状查找
关于这种疾病
Tissue damage caused by freezing temperatures or frost, which ice the water inside plant cells and destroy leaf and stem tissue — symptoms often become apparent only after thawing.
主要症状
- Leaves become water-soaked in appearance and turn translucent or soft
- After thawing, the plant remains collapsed and does not recover
- Affected areas turn brown to black and dry out or die
- Cacti may develop sunken, discolored patches on their surface
主要原因
- Prolonged exposure to sub-zero temperatures outdoors or in unheated spaces
- Direct contact with frost or ice on the plant
- Delayed action in response to sudden temperature drops
- Cold-sensitive species left outdoors or unprotected through winter
预防（栽培环境与日常管理）
Bring plants indoors or under frost-free cover when temperatures are forecast to drop below 5°C. Keep cold-sensitive species indoors throughout winter. Protect plants with fleece or similar cover during sudden cold snaps.

Specialist nurseries can assess frost damage severity, advise on which parts may recover, and guide on setting up appropriate warm, dry conditions. Species-specific cold hardiness and overwintering methods can also be discussed.
