Lower air temp. to near 32°F/0°C for a few days before transplanting into the field. Properly hardened plants can take temps. as low as 20°F/-7°C. EARLY SUMMER CROPS: Can be sown every 10 days, from Mar. 20th till July, 3 seeds per in/25 mm. Thin when seedlings have developed about 2 or 3 leaves to 12 in/31 cm apart.
