Grow a Garden Candy Corn? Facts & How-To
No, you cannot grow candy corn from seeds—it is a confection made of sugar, corn syrup, and wax, not a plant. However, you can grow the real vegetable that inspired its name: candy corn squash, a small ornamental corn with white, orange, and yellow kernels. This article explains the difference, how to grow candy corn squash, and what to expect from the plant.
What Is Candy Corn Squash?
Candy corn squash is a variety of ornamental corn (Zea mays) bred for its colorful kernels, which resemble the candy. Unlike sweet corn, it is not eaten fresh; it is grown for decoration, autumn displays, and sometimes for popping (though not all ornamental corn pops well). The plant grows 5–7 feet tall, with each stalk producing one to two ears. The kernels are hard and dry at maturity, and the ears are typically 6–8 inches long.
How to Grow Candy Corn Squash
Growing candy corn squash is similar to growing any field corn, but you need patience and space. Here are the key steps:
- Plant after the last frost – soil temperature should be at least 60°F (15°C).
- Choose a sunny spot – full sun (6+ hours daily) is essential.
- Space seeds 9–12 inches apart in rows 30–36 inches apart. Plant 2 seeds per hole, thin to one strong seedling.
- Water regularly – about 1 inch per week, especially during pollination.
- Fertilize lightly – corn is a heavy feeder; use a balanced fertilizer at planting and side-dress when plants are knee-high.
- Harvest when the husks are brown and kernels are hard – usually 85–100 days after planting.
If you want to save seeds, let the ears dry fully on the stalk, then shell and store them in a cool, dry place.
Choosing the Right Variety
Not all ornamental corn is the same. Look for seeds labeled “candy corn,” “ornamental corn,” or “Indian corn.” Some varieties are specifically bred for the tri-color pattern (white, orange, yellow). Check the seed packet for days to maturity—shorter-season varieties (80–90 days) are better for northern climates. If you only want the look, you can also grow regular sweet corn and leave it to dry, but the kernels won’t have the candy corn colors.
Common Problems and How to Avoid Them
- Poor pollination – corn is wind-pollinated. Plant in a block (at least 4 rows) rather than a single long row to improve kernel set.
- Pests – corn earworms and raccoons are common. Use row covers early, and harvest before animals get to it.
- Mold on ears – dry ears need airflow. Harvest promptly and dry in a warm, dry place with good ventilation.
- Stunted growth – usually from cold soil or lack of nitrogen. Wait for warm soil and fertilize.
If you see tassels but no ears, the issue is often pollination or stress (drought, heat).
Costs and Where to Get Seeds
Seeds are inexpensive—a packet of 50–100 seeds costs a few dollars at garden centers or online seed catalogs. You can save seeds from your own harvest, making it a one-time purchase. The main cost is space: each plant needs about a square foot, and you need multiple plants for good pollination.
Safety and Edibility
Candy corn squash is not toxic, but it is not meant to be eaten fresh. The kernels are hard and starchy. You can grind them into cornmeal or pop them (if the variety pops), but the flavor is not like sweet corn. Do not eat ornamental corn that has been treated with pesticides or dyes. Always wash hands after handling dried corn, as it can carry mold spores.
Frequently Asked Questions
Can I grow candy corn from the actual candy? No, candy corn is made from sugar, corn syrup, and wax. It contains no viable seeds. You need to buy seeds of the squash variety.
How long does candy corn squash take to grow? Typically 85–100 days from planting to harvest. Check your seed packet for the exact days to maturity.
Can I eat candy corn squash? It is edible but not tasty fresh. You can grind it into cornmeal, but most people grow it for decoration.
Do I need more than one plant? Yes, corn is wind-pollinated. Plant at least 4–6 plants in a block to ensure good kernel development.
Can I grow it in a pot? It is possible but not recommended. The plants are tall and need a lot of space. A container would need to be at least 5 gallons, and you would need several pots for pollination.
What do I do with the ears after harvest? Dry them in a warm, dry place for 2–3 weeks, then use them in wreaths, centerpieces, or as autumn decorations. You can also shell the kernels for birdseed or crafts.
