Storage & Preservation

After harvest, continue drying Reid's Yellow Dent until moisture content reaches 14% or lower – kernels should be so hard they barely dent under pressure. Spread unhusked ears on screens or hang in braids in a well-ventilated area for 4-6 weeks. Once fully dried, remove husks and store whole ears in breathable containers like mesh bags or wooden crates.

Properly dried corn stores for years in cool, dry conditions below 70Β°F with low humidity. Check periodically for signs of mold or insect activity. For grinding into meal, remove kernels by twisting ears against a hardware cloth screen. Store shelled corn in airtight containers with bay leaves to deter weevils. Whole kernels can also be prepared as hominy by soaking in lye solution, or ground fresh for cornmeal using a grain mill or high-powered blender.

Frequently Asked Questions

How long does Reid's Yellow Dent corn take to grow?β–Ό
Reid's Yellow Dent requires 110-120 days to reach full maturity. Unlike sweet corn, this field corn must dry completely on the stalk before harvest, often extending growing time into late fall. In zones 5-6, start seeds indoors in early spring to ensure adequate growing season length.
Can you eat Reid's Yellow Dent corn fresh off the cob?β–Ό
No, Reid's Yellow Dent is a field/dent corn variety bred for grinding into meal and animal feed, not fresh eating. The kernels are starchy and tough when fresh. This corn is harvested after full maturity and drying, then ground into cornmeal or used for hominy production.
Is Reid's Yellow Dent good for beginner gardeners?β–Ό
Yes, Reid's Yellow Dent is considered easy to grow with good natural pest resistance. However, beginners should understand it requires a long growing season, block planting for proper pollination, and space for tall stalks. The main challenge is timing harvest correctly for proper kernel drying.
How much space does Reid's Yellow Dent corn need?β–Ό
Plant Reid's Yellow Dent in blocks rather than rows for wind pollination. Minimum spacing is 6-8 inches between plants with 30-36 inch row spacing. A 4x4 block is the smallest recommended planting, though larger blocks produce better kernel fill and higher yields.
When should I plant Reid's Yellow Dent corn?β–Ό
Plant Reid's Yellow Dent after soil temperatures reach 60Β°F and all danger of frost has passed. In most areas, this means late May to early June. Northern gardeners (zones 5-6) may need to start seeds indoors 2-3 weeks before last frost to ensure the full 110-120 day growing season.
What's the difference between Reid's Yellow Dent and sweet corn?β–Ό
Reid's Yellow Dent is a field corn variety bred for drying and grinding into meal, while sweet corn is harvested young for fresh eating. Reid's has starchy, hard kernels when mature and requires 110-120 days versus sweet corn's 60-90 days. The growing methods differ significantly in harvest timing and intended use.
