Cucumber Sakamari F1 Seeds Japanese English-Type by Franchi Seeds

Sakamari F1 is a mid-early Japanese cucumber in the smooth English style. Dark green, straight fruits with very few spines, excellent fresh flavour and almost no bitterness. Vigorous, productive and disease-tolerant.

Ideal for greenhouses, polytunnels and other protected environments in Ireland. Performs especially well in cooler climates. Slice into salads, make raita, or eat straight from the vine with a pinch of salt.

🌱 Sowing information
Sow March–July indoors in small pots or modules of free‑draining compost. Place seeds on edge 2–2.5 cm deep, keep at 20–25 °C and give strong light to prevent legginess. Pot on and plant into large containers or greenhouse borders once sturdy and frost risk has passed.
☀️ Light exposure
Needs a warm, bright position such as a greenhouse, tunnel or sunny conservatory. Provide full light with slight shading during the hottest hours and ensure good ventilation for steady growth.
💧 Water needs
Keep soil or compost consistently moist; never allow plants to dry out, especially during flowering and fruiting. Water at the base to reduce mildew risk and maintain humidity by damping paths in hot weather.
🌡️ Germination temperature & time
Germinates best at 20–25 °C, usually within 5–10 days. Use a heated propagator or warm windowsill for early sowings; later sowings can be made without extra heat.
📏 Plant spacing & final size
Space plants 45–60 cm apart in borders or large containers (25–30 cm pots or grow bags). Train the main stem up a cane, string or trellis; pinch out the tip at the top support and manage side‑shoots for easy harvesting.
🌼 Harvesting notes
Pick fruits when medium‑sized, firm and evenly green. Harvest regularly to encourage continuous flowering and fruiting throughout the season.
