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).

Mid-summer. Good rain expected. Last chance for late maize (yield risk). Vegetables thrive — harvest and succession-plant.

Good mixes: Vetch, Fodder radish, Rye

Most versatile winter cover for the Free State. Plant early (March–April) for maximum biomass. Dual-purpose: cover crop + emergency grazing.

Benefits:

Most cold-tolerant cover crop Allelopathic weed suppression Deep fibrous root system Excellent soil structure improvement Survives hardest Free State winters

Good mixes: Vetch, Oats, Fodder radish

Best choice for fields with bad weed pressure — the dense mulch mat after rolling suppresses germination. Allow 3 weeks between termination and cash crop planting.

Termination: Spray or roll at flowering. N-release peaks 2–4 weeks after termination

Benefits:

Major nitrogen fixer Reduces fertiliser cost for following crop Good bee forage when flowering Improves soil biology Partners well with grasses

Good mixes: Oats, Rye

Always inoculate seed with correct Rhizobium if planting for the first time. The oats + vetch combination is the gold standard winter cover for the Free State.

Winter (autumn plant)

Seeding Rate

5–8 kg/ha

Growth

60–90 days (before winter kill)

Frost: Tender — killed by hard frost (below −5°C) N-fix: None — but scavenges nutrients from deep in the profile

Termination: Self-terminates via winter frost. No action needed — taproot decomposes leaving channels

Benefits:

Deep taproot breaks compaction (30–60 cm) Creates bio-drill channels for water infiltration Scavenges nutrients from subsoil Reduces need for mechanical ripping Self-terminates in winter

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.

Early autumn. First frost imminent. Focus on frost-hardy crops. Winter wheat planting begins.

First frosts typically arrive late April to mid-May. Protect tender crops.

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.

Type

Grass

Season

Winter

Seeding Rate

40–60 kg/ha

Growth

90–120 days

Frost: Hardy (to about −8°C) N-fix: None — but scavenges residual nitrogen, preventing leaching

Termination: Roll/crimp at boot stage, or spray with glyphosate before heading

Benefits:

Quick establishment Excellent erosion control Good livestock grazing Weed suppression Improves soil structure

Good mixes: Vetch, Fodder radish, Rye

Most versatile winter cover for the Free State. Plant early (March–April) for maximum biomass. Dual-purpose: cover crop + emergency grazing.

🌾

Rye (Secale)

Terminate Grass

Terminate at boot stage for best mulch mat. Thick residue suppresses early weeds.

Type

Season

Winter

Seeding Rate

25–35 kg/ha

Growth

120–150 days

Frost: Very hardy (to about −15°C) N-fix: None — strong nutrient scavenger

Termination: Roll/crimp at boot stage. Creates dense mulch mat that suppresses weeds for weeks

Benefits:

Most cold-tolerant cover crop Allelopathic weed suppression Deep fibrous root system Excellent soil structure improvement Survives hardest Free State winters

Good mixes: Vetch, Oats, Fodder radish

Best choice for fields with bad weed pressure — the dense mulch mat after rolling suppresses germination. Allow 3 weeks between termination and cash crop planting.

Benefits:

Major nitrogen fixer Reduces fertiliser cost for following crop Good bee forage when flowering Improves soil biology Partners well with grasses

Good mixes: Oats, Rye

Always inoculate seed with correct Rhizobium if planting for the first time. The oats + vetch combination is the gold standard winter cover for the Free State.

Soybean

Plant (late)

Last planting — short-season cultivars only.

🌾

Sorghum

Plant

Can still plant — more heat/drought tolerant than maize.

🫘

Dry beans

Plant / Growing

Last planting for the season.

🌻

Sunflower

Growing

Oct/Nov plantings in active growth.

🌱

Cowpeas

Plant (late) / Growing Legume

Last planting window. Nov plantings now in active growth and N-fixation.

Type

Legume

Season

Summer

Seeding Rate

15–25 kg/ha

Growth

60–90 days

Frost: Tender — killed by any frost N-fix: 60–100 kg N/ha

Termination: Frost-killed naturally, or roll/spray before cash crop planting

Benefits:

Heat and drought tolerant Excellent nitrogen fixer Good livestock forage (high protein) Suppresses weeds Tolerates poor sandy soils

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

Growing Legume

Rapid height gain — providing excellent weed shading.

Type

Legume

Season

Summer

Seeding Rate

15–20 kg/ha

Growth

60–90 days

Frost: Tender — killed by frost N-fix: 100–150 kg N/ha — one of the best N-fixers

Termination: Roll/crimp or spray before frost. Thick stems create lasting mulch

Benefits:

Highest N-fixation of summer covers Rapid growth (2–3 m tall) Excellent nematode suppression Good weed shading Produces massive biomass

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 Grass

Can still plant — heat-loving. Nov plantings growing vigorously.

Type

Grass

Season

Summer

Seeding Rate

10–15 kg/ha

Growth

90–120 days

Frost: Tender — killed by frost N-fix: None — but produces massive root biomass feeding soil biology

Termination: Frost-killed or roll/spray. High C:N ratio residue lasts long as mulch

Benefits:

Deep roots break compaction Drought and heat tolerant Massive above and below-ground biomass Excellent for sandy soils Provides emergency grazing

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 Mix

Multi-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.
