Eastern Free State · What to plant each month for vegetables, field crops, and cover crops
Eastern Free State Frost Regime
Last frost typically mid-September to mid-October. First frost late April to mid-May. Growing season approximately 210–240 frost-free days. Altitude 1 500–1 700 m.
What are cover crops?
Cover crops are non-cash crops planted to protect and improve soil between main crop seasons. They fix nitrogen (legumes), prevent erosion, suppress weeds, break compaction, and build soil health. Two main windows: winter covers (oats, rye, vetch — planted Mar–May) and summer covers (cowpeas, sunn hemp, sorghum — planted Oct–Dec).

Termination: Self-terminates via winter frost. No action needed — taproot decomposes leaving channels
Benefits:
Good mixes: Oats, Rye, Vetch
Plant by mid-April so taproot develops fully before frost kills the plant. The decomposing root channels dramatically improve water infiltration in compacted soils.
Deep winter — heavy frost expected. Focus on hardy greens and root vegetables.

Regular — keep evenly moist. Shallow-rooted; frequent light watering.
Fastest vegetable — perfect filler crop. Sow every 2 weeks for succession. Don't let them get old and woody.

Regular and deep — critical during tasselling and silking. 25–30 mm/week.
Plant in blocks (not single rows) for better pollination. Successive plantings every 3 weeks.

Tender
Regular and deep — 25–40 mm/week. Water at base to avoid foliage diseases.
Start indoors or use transplants. Plant after last frost. Support with stakes or cages.

Termination: Frost-killed naturally, or roll/spray before cash crop planting
Benefits:
Good mixes: Babala, Forage sorghum, Sunn hemp
The go-to summer legume cover for the Free State. Works well between wide-row maize. Can be grazed — leave 15 cm stubble for regrowth.
Sunn hemp

Termination: Roll/crimp or spray before frost. Thick stems create lasting mulch
Benefits:
Good mixes: Cowpeas, Babala, Forage sorghum
Needs warm soil (>18°C) — don't rush planting. The tall, thick stems create a lasting mulch layer when rolled. Excellent before maize in rotation.
Forage sorghum
Plant (late) / Growing GrassCan still plant — heat-loving. Nov plantings growing vigorously.

Seeding Rate

Termination: Frost-killed or roll/spray. High C:N ratio residue lasts long as mulch
Benefits:
Good mixes: Cowpeas, Lablab, Sunn hemp
Best grass option for summer cover on the highveld. Deep roots improve water infiltration in compacted fields. The high C:N residue takes longer to decompose — good for lasting mulch.
Multi-species mix
Growing MixMulti-species summer mixes provide maximum soil biology diversity and resilience.
Planting recommendations are based on general Eastern Free State conditions (1 500–1 700 m altitude, ~600 mm annual rainfall). Adjust for your specific micro-climate, soil type, and frost exposure. Field crop data based on ARC/UFS trial results and SA Grain guidelines.
