Sweetcorn Growing & Male Flowers (tassels)
As the plants are wind pollinated they should be grown in blocks rather than rows, 45cm (18in) apart. Conversely, there are some mini sweet corn cultivars which are harvested before fertilisation, and so don't need to be grown in a block and can even be grown as a windbreak.
Grow sweet corn in a sheltered, sunny position, protected from strong wind, on any fertile garden soil. Add up to two bucketful’s of organic matter, such as rotted manure, and also rake in 100g per sq m (3oz per sq yd) of Growmore before planting. Plants are less successful on dry or heavy soil.
Mulch with organic matter, to conserve moisture and suppress weeds and mound soil over the roots, which appear at the base of the stems. Hoe carefully as they are shallow rooted.
Stake plants individually if they are tall or the location is exposed.
Water well in dry weather; this is vital when the plants are flowering. Tap the tops of the plants when the male flowers (tassels) open to help pollination; poor pollination results in sparsely filled cobs. Liquid feed when the cobs begin to swell.
