Quicky Sweet Corn Close To Maturity

Growing Sweet Corn

Sweet corn, feed corn, and popcorn, there is a huge number of corn varieties the home gardener can choose to grow, from dwarf to standard and sweet to sweeter.

In the small home garden sweet corn is often not grown because, like potatoes, it takes up a lot of space. Corn is vulnerable to wind, especially in small plots, hates the frost, demands a big share of any soil nutrients and is often plagued by weeds and disease.

To compound those issues, corn and has more than its share of pests and critters waiting to beat you to the first bite.

So, why bother growing sweet corn? Because there truly is no sweeter taste than that of corn that is eaten within minutes of being picked.
