Early Spring Division Damage: Cold Injury on Disturbed Sarracenia and Drosera

Why Dividing Too Early in Cold Climates Kills Plants

Illinois grower (Zone 5) divided S. 'Dana's Delight', S. leucophylla, D. tracyi, VFTs 2 weeks ago (3 weeks out of winter storage). Temps dropped to low 20s°F despite row cover. Plants show burn/rot. Undivided plants fine.

Expert Diagnosis (Jeff Dallas)

Divisions lose cold tolerance. Nursery divides in March when lows rarely below 28°F briefly. Zone 5 low 20s°F damages disturbed plants. D. tracyi not very cold-hardy. VFTs less hardy if transplanted mid-winter. S. leucophylla (southern origin) less hardy—'Tarnok' hardier than 'Titan'.

Follow-Up: Undivided S. purpurea Also Burned

Jacob Farin: Photos show frost + sun damage on exposed crowns. Old leaves sheltered crowns; removal + late frost + bright sun = burn. Not rot. Plants will acclimate; new growth coming. Shelter only for forecast frost.

Key Lessons

• Wait for moderated weather before dividing (local gardening guides).
• Row covers only help light frost.
• Don't remove all old leaves until frost risk passes—they protect crowns.
