Troubleshooting
Tartarian Sea Kale problems — and how to fix them
Tartarian Sea Kale (Crambe tataria) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root rot from winter wet
The deep taproot is highly susceptible to rot if soil becomes waterlogged over winter; plant on a raised bed, slope, or in very free-draining soil — this is the primary reason for plant death in cultivation.
Poor germination from old seed
Seed viability drops rapidly; sow fresh seed in autumn with cold stratification, or crack the outer hull and cold-stratify for at least 30 days at 4°C before spring sowing. Old or poorly stored seed will fail almost entirely.
