To make good profit from cucumbers, the best strategy is to plant when few farmers have cucumbers in the market.
In Zambia, cucumber prices are usually high during the cool dry season and early hot season because supply is low.
Below is a simple guide for Local Cucumber vs English Cucumber.
1. Local Cucumber (Open Field)
Best Planting Time for Profit
✅ February – March
Harvest: April – May
Reason: Most rainy season crops finish and supply reduces.
✅ May – June (Very profitable)
Harvest: July – August
This is the cold season when cucumber supply is low, so prices go up.
✅ September – October
Harvest: November – December
Demand is high because of hot weather.
Avoid Planting
❌ December – January
Heavy rains cause diseases.
Many farmers plant at this time, causing oversupply and low prices.
2. English Cucumber (Greenhouse or Irrigation)
English cucumber normally sells to supermarkets, lodges, and restaurants, so timing is important.
Best Planting Time for Profit
✅ April – May
Harvest: June – August
Few cucumbers in the market → very high prices.
✅ July – August
Harvest: September – October
Demand increases due to hot weather.
Advantage of English Cucumber
-Higher price per kg
-Longer shelf life
-Preferred by supermarkets
3. Market Opportunities
Good markets for cucumbers include:
-Local Markets
-Supermarkets and lodges
During June, July and August, cucumber prices usually become 2–3 times higher than during rainy season.
4. Production Tips for Profit
🌱 Plant in stages every 2–3 weeks so you harvest continuously.
-đź’§ Use irrigation during the dry season.
-🦠Spray early for aphids, whiteflies and mildew.
-📦 Harvest when fruits are still young and fresh because buyers prefer that.
here is a simple explanation of how farmers can make K15,000 – K40,000 from 1 lima of cucumbers and the spray program for cucumbers.
HOW FARMERS MAKE K12,000 – K30,000 FROM 1 LIMA OF CUCUMBERS
5. Yield from 1 Lima
If cucumbers are well managed, 1 lima (about 0.25 hectare) can produce:
4,000 – 6,000 cucumber fruits.
If you sell cucumbers in bundles or per fruit:
Example:
1 cucumber = K3 – K5 (depending on season)
Calculation example:
4,000 cucumbers Ă— K3 = K12,000
6,000 cucumbers Ă— K5 = K30,000
This is why farmers can make K12,000 – K30,000 per crop cycle.
Cucumbers start harvesting 35–45 days after planting and harvesting continues for 3–4 weeks.
6. Spray Program for Cucumbers
Cucumbers are attacked by aphids, whiteflies, red spider mites and fungal diseases.
Early spraying is important.
Week 1–2 (After Germination)
Spray for sucking pests.
Example chemicals:
Imidacloprid
Lambda-cyhalothrin (active ingredient)
Spray once every 7 days.
Week 3–4
Start spraying for diseases.
7. Common diseases:
-Powdery mildew
-Downy mildew
Example fungicides:( when buying chemicals, go for active ingredient, not brand name)
Mancozeb
Metalaxyl
NOTE
Spray every 7 days
Week 5 Until Harvest.
Combine insecticide + fungicide.
Example program:
Monday: Insecticide
Friday: Fungicide
Always rotate chemicals to avoid resistance.
8. Fertilizer Program
Good fertilizer increases cucumber yield.
At Planting
Apply:
Basal fertilizer
2 Weeks After Planting
Apply:
Top Dressing
During Flowering
Apply:
Fertilizer with NPK 20:20:20 or foliar fertilizer
This helps plants produce many fruits.
9. Important Tips for Profit
🌱 Plant during May–June or July for high prices.
-đź’§ Water cucumbers every day during dry season.
-🌿 Remove weeds early.
-📦 Harvest cucumbers every 2 days to encourage more fruits.
10. âś… Secret of successful cucumber farmers:
Plant when few farmers are planting.
Maintain good spraying program.
Conclusion 🌾
Cucumber farming is a very profitable short-term crop for farmers who manage it properly.
With good planning, spraying, and market timing, even a small area like 1 lima can generate thousands of kwacha within two months.
Farmers are encouraged to treat cucumber farming as a business and not just a garden crop.
