Seneca Horizon is an early producing variety of Sweet Corn. It is known to give very reliable and abundant yields. Most early corn varieties produce relatively small ears of corn. One of the best early producers - Early Sunglow - produces ears that are only 6.5 to 7 inches long, Seneca Horizon, although it does not produce AS early, yields ears of corn a hefty 8 - 10 inches long and just as sweet.
Some seed companies are touting this variety as maturing in 65 - 70 days. While that may well be the case if you are growing miniature baby corn, it is not so if you're aiming for full grown corn on the cob. Anticipate a worse case scenario of 85 days, under optimal conditions 70 - 75 days.
The Corn stalks reach about 5 to 5.5 feet tall and typically produce 1 or 2 ears per stalk.
Corn Should be planted in blocks as opposed to rows and should not be planted near other varieties of Corn [See - Isolating Sweet Corn.] Cross pollination tends to produce poor tasting starchy corn.
Seneca Horizon can be seeded directly into the soil, or it can also be started indoors and later transplanted. Whichever mode you choose, Plant it in blocks, at least four rows wide, for proper pollination and well-filled ears
Corn has shallow roots, and uses a lot of nitrogen as well as trace elements. To help your crop get off to the best start possible, prepare the soil first with a nitrogen-rich fertilizer. Well rotted manure or compost is also helpful.
Plant in the northern side of the garden as corn stalks will deny sunlight to the rest of your garden crops ,you also might want to grow some where it will provide shade to plants that can not tolerate full sunlight.
