Thompson & Morgan®: Vegetable Growing Guide
Sow the seed individually in 3in (7.5cm) pots indoors in early spring or outdoors 1½in (3.5cm) deep, after the last frost and when the soil is warm, where the crop is to mature. Indoor the seeds prefer a soil temperature of 70-75F (21-24C) for best germination.
Plant out in early summer in BLOCKS 1-2ft (30-60cm) each way, depending on the variety. This is an aid to pollination and the other is to tap the top of the stem to transfer pollen from the male flowers to the female ones below.
Most plants will produce two cobs, the first being larger than the later second.
To test the cob for ripeness, press a grain with a finger nail and if the juice is milky, it is just right.
