Seedling
10-14 daysCotyledons emerge followed by first true leaves. Plant is 2-4 inches tall with delicate foliage.
Maintain consistent moisture and warm soil (70-85°F). Provide bright light to prevent legginess. Thin seedlings to strongest if direct seeding.
Vegetative
20-25 daysPlant develops multiple stems and expands to full compact bush form (12-18 inches). Vines produce 4-6 true leaves before flowering begins.
Support plant structure with mulch if needed. Begin fertilizing with balanced fertilizer every 2-3 weeks. Ensure consistent watering and full sunlight exposure.
Flowering
7-10 daysSmall yellow flowers appear at leaf axils on both main stems and side branches. Male and female flowers develop; female flowers have immature fruit behind the bloom.
Maintain steady nutrition and moisture; avoid excess nitrogen which delays fruiting. Ensure pollinators have access or hand-pollinate if needed. Continue weekly watering.
Fruiting
35-45 daysSmall green fruits develop rapidly from pollinated female flowers, reaching 6-8 inches at maturity. Plant continues producing new flowers and fruits throughout season.
Increase watering to 1-2 inches weekly as plant bears fruit. Support developing fruits on trellises if desired. Fertilize every 2 weeks with balanced or slightly potassium-rich formula.
Harvest
20-30 days (multiple harvests)Fruits are dark green, firm, 6-8 inches long, with slight bumpy texture. Plant remains productive if harvested regularly.
Pick fruits when they reach desired size; regular harvesting encourages continued production. Handle fruits gently to avoid bruising. Continue watering and feeding to sustain yields.

Harvest Tips
Pick cucumbers when they are 6-8 inches long and dark green; smaller fruits are more tender and flavorful. Harvest every 2-3 days during peak season to encourage continued flowering and fruiting. Use pruning shears or a knife to cut the stem rather than pulling to avoid damaging the vine. Morning harvest preserves crispness. Fruits left on the vine too long become yellow, seedy, and bitter.
