Description

In Corvallis, Oregon, the late Dr. Alan Kapuler bred this sweet corn for color and eating quality that show up clearly in the garden and on the plate. Double Red Corn produces deep red kernels packed with a sweet, rich flavor, and the stalks themselves are a striking red as well. It is described as loaded with antioxidants, combining strong pigmentation with a nutritious profile. The overall effect is a corn that brings taste and intense red color together in one planting.

Growing Guide

When to Grow

Sow Double Red sweet corn seeds directly outdoors after the last frost date in your area, when the soil temperature reaches at least 60 F. The ideal growing temperature is 75-80 F. Check local frost dates to determine the best planting time for your region. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Direct sowing is recommended for sweet corn as it does not transplant well. Plant seeds 1-2 inches deep, spaced about 12 inches apart in rows 24-36 inches apart. Thin seedlings to the strongest plant per spacing once they reach a few inches tall to ensure healthy development. Plant in blocks to improve pollination.

How to Grow

Ensure consistent watering, particularly during critical growth stages. Fertilize regularly with a balanced fertilizer or organic compost to support vigorous growth. Weed around the plants to prevent competition for nutrients and water. Applying mulch can help conserve moisture and reduce weed growth. Tall plants may need staking to prevent wind damage.

How to Save Seeds

  • Corn is wind pollinated and will easily cross with other varieties (including GMO corn!). You will need at least 1 mile of isolation to avoid cross pollination. You can also use staggered timing or caging techniques.
  • Hand pick ears when fully dried on stalk. Seeds keep best if left on the ear; just remove at planting time.
  • Sweet corn seeds will remain viable for 2 years; dent corn will last up to 5 years when properly stored.
