Seed & start
Pre-culture recommended
Start indoors / cold frame first, transplant into the raised bed later.
Stachi's tip
Sweet corn needs warmth, water and patience. Plant in a block (min. 3×3 rows) not a single row — wind needs to distribute pollen. Classic three-sisters partner to bean and squash.
