When to plant, how far apart, which variety, how to feed it and which pests to watch for. The same guide the AsaaseYaa app uses to plan your tomato jobs day by day.
When to plant
| Where | Season | Months |
|---|---|---|
| South and middle belt | Dry Season | Nov – Feb |
| South and middle belt | Season 1 | Mar – Apr |
| Northern regions | Dry Season (Irrigation) | Oct – Feb |
| Northern regions | Early Rains | Apr – May |
In the app, the dates follow your region, and the jobs follow the rain forecast for your farm.
Getting the land ready
- Feeding: Compost or well-rotted manure. Apply well-composted organic matter before ridging or bed preparation. If soil is acidic, apply agricultural lime 2 weeks before planting.
- Weeds: Thorough land preparation, black plastic mulch optional. Thorough land preparation before transplanting removes most weed competition. Black plastic mulch is effective but expensive; straw mulch is a practical alternative.
- Pests: Rotate tomato with non-solanaceous crops to break disease cycles. Tomato-after-tomato increases nematode and Fusarium wilt risk significantly.
Varieties grown in Ghana
High-yielding hybrid, firm fruit. Widely planted in Akumadan and the Upper East tomato belt.
Hybrid with good tolerance to bacterial wilt — important in humid forest zones.
Open-pollinated, processing-friendly Roma type. Verticillium + Fusarium tolerance.
Adds root-knot nematode tolerance on top of Roma VF — useful on land where vegetables have been planted before.
Care through the season
Establishment
- Feed: NPK 12-24-12 or Di-Ammonium Phosphate (DAP), 30 kg per acre. Apply in planting hole or as ring placement 5 cm from transplant base.
- Weed: Weed every 10–14 days for first 6 weeks.
- Watch for: Cutworm, Damping-off disease, Whitefly. Scout daily for first 2 weeks.
Vegetative growth
- Feed: NPK 15-15-15, 25 kg per acre, every 3 weeks. Ring placement 10 cm from plant base, water after application.
- Weed: Every 2–3 weeks.
- Watch for: Whitefly, Aphids, Spider mites, Leaf miners. Scout twice weekly.
Flowering
- Feed: MOP 60% + Calcium foliar spray, 20 kg per acre + foliar calcium spray. Drench at base; foliar spray in morning, avoid flowers.
- Weed: Once if needed.
- Watch for: Thrips, Whitefly, Blossom drop (heat/water stress). Scout twice weekly.
Fruiting
- Feed: Potassium foliar + Calcium spray, Foliar only, weekly. Foliar spray in the cool of the morning, avoid ripe fruit.
- Weed: Minimal.
- Watch for: Tomato fruit borer, Anthracnose, Blossom end rot. Scout every 2–3 days.

Harvest and storage
It is ready when:
- Fruit has turned to breaker stage — first blush of pink or red at the blossom end
- Fruit is firm but gives slightly under gentle pressure
- Fruit detaches cleanly from the calyx with a slight twist
- Seeds inside are fully formed and surrounded by gel
Harvest at breaker to pink stage for market — allows 3–5 days shelf life. Harvest at full red only for immediate sale or processing. Pick gently with a slight twisting motion. Avoid harvesting in the hottest part of the day.
- Sort immediately — remove cracked, diseased, or overripe fruit
- Place in clean plastic crates or wooden boxes lined with soft material
- Grade by size and colour uniformity for market premium
- Cool in shade before transport — avoid stacking more than 3 crates high
Breaker-stage tomatoes last 5–7 days at room temperature in shade. Refrigeration (10–13°C) extends to 2 weeks but reduces flavour. Do not store tomatoes in direct sun.
What to plant next
Avoid tomato or pepper next year. Solanaceae → cereal/legume rotation is critical. Persistent Ralstonia solanacearum + nematode populations otherwise cripple the next season.
General advice from crop guides for Ghana. Check important decisions with an agronomist or your district agriculture office.
