Taste, sweetness and yield are the chief considerations of most gardeners when choosing corn varieties. We have carefully selected our varieties to cater to these demands. Approximately 5 seeds/gram.
Hints:

The ground must be warm and moist for the corn seed to start to germinate. Early planting does not increase yield.

Corn can be transplanted. Peat pots can help avoid transplant shock.

Plants 3-5 seeds approximately 30 cm apart and 2 cm deep in blocks of 4 rows for wind and pollination factors.

Try 6-10 plants in large [25 litre] black plastic pots. It will keep the roots warm for earlier harvest.

Harvest when kernels are full and the juice inside them is 'milky'.

Early Xtra-Sweet - 75 days from emergence. An early super sweet corn with ears 18-23 cm [7-9"] long. Plant height 1.5-1.8 m [5-6'] Very high sugar content. MUST BE GROWN IN ISOLATION FROM OTHER CORN.
