Growing Calendar for Sweetcorn Seeds - Mainstay F1 Hybrid
Delivery: 5-7 Working Days
Sweetcorn Mainstay F1 Hybrid is a tall, robust grower that produces 'super-sweet' cobs ready to harvest after sweetcorn Earlibird. So sweet you can eat fresh from the plant for a delicious snack. An excellent way of getting healthy vegetables into kids – this sweetcorn is sweet and colour – so appeals a lot to children.
We recommend you sow indoors from April to May for an earlier harvest. Sow ½ inch (1cm) deep in individual module seed trays of pre-watered compost lightly firm down. Place in a warm environment at around 21°C (70°F). A plastic lid over you module seed tray placed on a sunny windowsill will attain this temperature. Keep the compost moist at all times.
Plant out seedlings in June. Harden off young plants before plating out (bring the module tray outside by day and bring indoors by night) in the required harvest position 36in (90cm) apart when risk of frost has past.
Alternatively sow outdoors from May to June ½in (1cm) in their permanent planting positions. Keep soil moist at all times.
Tip - Pick regularly when fruit is 4in (10cm). Water plants regularly. Once fruits starts to swell feed with a liquid fertiliser.
