Trinity Sweet Corn
✓ In your garden
Trinity is a bicolor sweet corn (sugary-enhanced (se)), ready in about 70 days. It’s a sugary-enhanced (se) type — sweeter and more tender, and it holds its sugar a little longer. Plant sweet corn in a block of several short rows, not one long one, so the wind pollinates it and every ear fills out. It’s ripe about three weeks after the silks show, when a poked kernel squirts milky.

Zone 6bGreenhouse or cover on: your start slides ~4 weeks earlier and your harvest stretches ~3 weeks later (shown striped).
Planting seeds straight in the ground only works where the season's long and warm — most gardeners start seeds indoors or buy young plants, or you'd pick your first tomato right as frost hits.
Comfortable — first ripe fruit lands around late Jun, well before your typical frost (~late Oct).

Corn earworm and tomato fruitworm are the same moth. Side by side, you're setting its table twice.

Growing Trinity — the things that trip people up
- Plant sweet corn in a block of at least four short rows rather than one long row — it’s wind-pollinated, and a block sets full, even ears while a single row leaves gappy cobs.
- Keep different sugar types apart (a couple hundred feet, or staggered planting), or cross-pollination between them makes the kernels tough and starchy.

Common questions about Trinity
How long does Trinity take to grow?
About 70 days, ripe roughly three weeks after the silks appear.
Why plant Trinity in a block?
Corn is pollinated by wind carrying pollen from the tassels down to the silks. A block of short rows pollinates far better than one long row, so the ears fill out completely.
