Cucumbers are warm-season vegetables planted outdoors no earlier than 2 weeks after last frost. Most varieties climb, fitting any space. Common slicing types grow on vigorous vines with large leaves; growth is fast, yield abundant with proper care.
Planting Cucumbers
- Seed/transplant outdoors ≥2 weeks after last frost. Soil ≥65°F for germination—don’t plant too early!
- Early crop: start indoors 3 weeks before transplanting. Bottom heat ~70°F (heat mat, or seeds on fridge/water heater).
- Site: full sun.
- Ideal soil: neutral/slightly alkaline (pH 7.0). Amend clay with organic matter; dense soil with peat/compost/rotted manure. Sandy soil preferred in north (warms fast). Test soil if unsure.
- Mix compost/aged manure 2 inches deep, work 6–8 inches deep. Soil moist, well-drained, not soggy.
- Sow seeds 1 inch deep, 6–10 inches apart in rows.
- Transplants: 12 inches apart.
- Trellis for climbing or limited space; protects fruit from ground moisture.
Care
- Cover seeds with netting/berry basket to deter pests.
- Water frequently at emergence; increase to 1 gallon/week after fruit forms.
- At 4 inches tall, thin to 1½ feet apart.
- Fertilize: if organic matter worked in, side-dress with compost/manure. Or use low-nitrogen, high-potassium/phosphorus fertilizer at planting, 1 week after bloom, every 3 weeks with liquid food. Or granular fertilizer worked in. Don’t overfertilize—stunts fruit.
- Water consistently: finger test—dry past first joint = water. Inconsistent water → bitter fruit. Water slowly morning/early afternoon, avoid leaves.
- Mulch to hold moisture.
- Trellis early to avoid damaging seedlings/vines.
- Spray vines with sugar water to attract bees, set more fruit.
Pests and Diseases
- First flowers often all male—be patient for female blooms.
- Poor pollination from rain, cold, insecticides. Gynoecious hybrids need pollinator plants.
- Cucumber Beetles
- Whiteflies
- Bacterial Wilt
- Anthracnose
- Mosaic Viruses
Harvest and Storage
- Slicing: 6–8 inches. Dills: 4–6 inches. Pickles: 2 inches. Burpless: up to 10+ inches.
- Pick before seeds harden, when immature. Don’t let yellow. Best: uniformly green, firm, crisp.
- Overripe = tough skins, lower productivity.
- Peak: pick every couple days.
- Keep picking—mature plants stop producing if not harvested.
- Cucumbers >90% water. Store tightly wrapped in plastic to retain moisture.
- Refrigerate 1 week–10 days.
