Troubleshooting
teff grass problems — and how to fix them
teff grass (Eragrostis tef) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Poor germination from improper seeding depth
Teff seed is extraordinarily small and must not be buried — seeds placed deeper than 6 mm (¼ inch) fail to emerge. Broadcast onto a very firm, moist seedbed and press seeds in with a roller or flat board, or use a grain drill set to minimum depth. Soil crust after rain can also prevent emergence; light irrigation prevents crusting.
Lodging in wet or high-fertility conditions
Excess nitrogen or irrigation causes teff stems to become top-heavy and fall over (lodge), making harvest difficult and reducing yield. Use moderate fertility, do not over-irrigate, and harvest hay before stems become too tall and heavy. Choose lodging-resistant varieties where available.
Frost kill at any growth stage
Teff is completely frost-intolerant — a single frost event kills plants at any stage of growth. Do not sow until soil temperature consistently exceeds 18°C (65°F) and all risk of frost has passed. In northern climates, the growing window is typically late May to early September.
