Baby corn is commonly added to Thai and Chinese cuisine, and looks just like miniature corn on the cob. Baby literally is immature corn that is harvested before it is fully grown. Baby Asian, Little Indian, Golden Midget and Candystick are some of the more popular sweet-corn cultivars. Baby corn is grown the same way as regular sweet corn, but it must be harvested at a specific time.
Prepare a large seed tray or a long trough with 6 to 12 inches of rich potting soil mixed with organic compost. Ensure that the tray or trough has drainage holes along the bottom.
Plant the corn seeds 8 to 9 inches apart in two or three rows spaced 18 to 24 inches apart. Place two or three seeds in 2-inch deep planting holes Thin out the seedlings after they emerge, leaving just one seedling in each spot.
Maintain soil temperatures of 65 to 75 degrees F. Allow for full light exposure at least six hours each day, placing the seeds in bright, direct sunlight in a window or hanging grow lights about 4 feet above the tray or trough.
Water the baby corn seeds every day to keep the soil moist until the seeds begin to sprout. Water the seedlings thereafter once every three or four days to keep the soil from drying out.
Feed the baby corn plants when they're about 1 to 1-½ feet tall with 1 tbsp. of 10-10-10 NPK (Nitrogen-Phosphorous-Potassium) fertilizer per 3 feet of row.
Harvest the baby corn within three days of the silks emerging.
