Description
This snack sized sweetcorn is becoming increasingly popular for its 15cm (6") long cobs with good tip fill and 16 rows of grains. Modern breeding of this RHS AGM variety has produced an extra tender cob with a fabulous taste, whether eaten raw from the plant, barbequed or steamed. With good plant vigour, Sweetcorn 'Picnic' is particularly useful in poorer soil conditions. Height: 200cm (79"). Height: 45cm (18").

Sowing

Sow sweetcorn seeds from April to May in 7cm (3") pots of free draining seed compost at a depth of 4cm (1 1/2"). Place in a propagator or seal the container inside a polythene bag at temperature of 18-24C (64-75F) until after germination which takes 7-10 days. After germination, grow sweetcorn plants on in cooler conditions until large enough to plant outdoors. When all risk of frost is passed, gradually acclimatise sweetcorn plants to outdoor conditions over 7-10 days before transplanting into fertile, well drained soil in full sun, with shelter from winds. The flowers of sweet corn are wind pollinated and should therefore be planted in blocks rather than rows to ensure good pollination. Allow at a distance of 30cm (12") between each plant.


Alternatively direct sow sweetcorn seeds outdoors in May once the soil has warmed, at a depth of 4cm (1 1/2") and a distance of 45cm (18") apart. Sow 2 seeds per hole and thin out the weakest seedling per station after germination.

More Info
Water sweetcorn plants regularly until established, particularly during dry periods. Provide a thick mulch of organic matter around the base of the plants to help conserve moisture and reduce weed growth. Sweetcorn plants are shallow rooted so take care when hoeing to prevent root damage. Harvest sweetcorn cobs when the silky tassles at the end of the cob have turned brown. Peel back the sheath of the cob slightly and press the corn kernels with a fingernail until liquid squeezes out. If liquid is milky coloured then the cob is ripe, if clear then it is under-ripe.
