Suggested Planting Requirements: Corn is a vigorous and fast-growing crop. For the best production, you will want to give it generous amounts of nitrogen phosphorus and potassium. You can do this by adding an all-purpose organic granular fertilizer at the time of planting. We also recommend adding compost or aged manure to the top 6″ of the soil. Corn needs full sun and warm weather to grow. For pollination purposes, you will want to plant corn in a block to ensure the pollen falls onto the tassels.
Growing Recommendations: Corn is typically directly sown in the ground. In protected gardens, this works well. If you have critters in your garden or issues with direct sowing you can transplant your corn seed as we do on our farm. The secret is to make sure you do not let the corn become root bound in the pots. When transplanting the corn, make sure you untwist the main root so that it dangles free at planting. This ensures they are not root-bound so that the transplants can grow freely.
Harvesting & Storage: Depending on the variety of corn, the harvest instructions vary. Sweet corn is harvested when the peak sugar has condensed in each kernel. This is typically about 17-25 days after pollination. Signs of maturity are: silks become dry, ears are tilted from the stem, and ears feel firm. When in doubt, peel back the husk and squeeze a kernel. If a milk juice comes out, it’s ready! Do not let sweet corn over ripen. Popcorn varieties are ready when the kernels are fully developed in the husk and hard to the touch. For dent and flint corn varieties, if the silk near the very tip of the ear of corn is dry, then the corn is likely too mature.
To store sweet corn, harvest whole ears and store in the fridge until ready for eating. Popcorn and flint corns can be stored dry until needed.
