Growing

Sorghum thrives in the heat, making it a reliable choice for the warm season when soil has warmed and frost is no longer a threat. Because this is an annual grain, you should sow the seeds directly into the garden where you intend them to grow rather than transplanting. When preparing your site, aim for well-drained soil and incorporate any necessary fertilizer into the earth before planting to prevent seedling damage from fertilizer burn. If you are working with sandy soil, you may plant the seeds slightly deeper than you would in heavier, clay-like soils.

Managing pests and diseases is vital for a healthy harvest. This crop is susceptible to various fungal issues, such as anthracnose, leaf blight, and smut, as well as bacterial leaf stripe. You may also encounter various insects, including aphids, grasshoppers, and stalk-boring caterpillars, which can significantly reduce biomass. To help maintain plant health, consider rotating your crops with legumes or leaving the area fallow for a period before planting.

Once the grain is ready to use, harvest it promptly, as the grain does not ripen further after being picked. For long-term use, keep your harvest unwashed and store it in a dry, cool, dark cellar or at room temperature. Always remember that the raw plant is toxic.
