Seedling
7-10 daysCotyledons emerge followed by first true leaves; plant is tender and delicate
Keep soil consistently moist; avoid direct scorching sun; thin seedlings to proper spacing once 2-3 true leaves appear
Vegetative Growth
15-25 daysMultiple true leaves develop, plant expands horizontally with savoyed, crinkled foliage becoming darker green
Maintain consistent moisture; ensure adequate spacing to prevent crowding; monitor for pests and diseases
Leaf Development
10-15 daysMature rosette of full-sized leaves reaches harvest-ready size with dense, attractive savoyed texture
Continue regular watering; watch for heat stress or bolting triggers; begin harvesting outer leaves once plant is 4-5 inches tall
Peak Harvest
7-14 daysPlant is fully productive with tender, flavorful leaves at optimal size before any bolting occurs
Harvest regularly to encourage continued production; keep soil cool with mulch; avoid excessive heat exposure
Bolting
Variable, typically triggered by heatFlower stalk begins to elongate from center; leaves become tougher and more bitter
Corvair is slow to bolt, but when it occurs, harvest immediately or remove plant; plant succession crops for continuous harvest
Common Pests
-
Row covers to prevent egg-laying; remove affected leaves; encourage beneficial predators; spinosad spray as last resort
-
Strong water spray; insecticidal soap; neem oil; encourage ladybugs and parasitic wasps
-
Increase humidity; spray with water; neem oil; avoid excessive heat stress
-
and
Hand-pick; copper barriers; beer traps; encourage ground beetles; remove debris and hiding spots
-

Harvest Tips
Begin harvesting outer leaves when plant is 4-5 inches tall; pick regularly to encourage continued production and delay bolting. Harvest in early morning when leaves are crisp and full of moisture. For whole plant harvest, cut 1 inch above soil line. Corvair matures in 40-50 days from sowing. Best flavor develops in cool weather (55-70°F); harvest before temperatures exceed 75°F to avoid bitter taste.
Fun Facts
- 🌱 Corvair was specifically bred for improved disease resistance and bolt tolerance, making it one of the most reliable modern spinach varieties for home gardeners who struggle with premature bolting.
- 🌱 Spinach does not contain exceptional amounts of iron compared to other greens; the myth originated from a misplaced decimal point in a 1870 nutritional study, but spinach remains nutrient-dense.
- 🌱 Corvair thrives in cool-season conditions and actually prefers temperatures between 50-70°F, making it perfect for spring and fall gardening when other crops may struggle with temperature extremes.
