When to sow seeds in North Texas

Every spring and fall, social media feeds devoted to gardening are filled with a single question: is it time to plant _________?

The answer to the question is somewhat answered by determining the area's average frost dates and using the USDA planting zones, but with unpredictable weather patterns and climate change, they're at best a general guide.

A more accurate look at when it's time to sow seeds comes from knowing what the optimum temperature is for a crop's seed to germinate. If it's March 15, the date of the average last frost in North Texas, but the soil temps are still cooler than a seed will germinate at, then it's not time to sow that seed.

For best results, sow seeds when the nighttime lows are within the range of optimum temperatures at which a crop's seed germinates.

This chart is a handy reference for knowing when to plant.

With sturdy stalks that grow tall and produce ears that are eight inches long with sixteen to eighteen rows of kernels in varying colors, Petmecky corn is a flint or flour type of corn that can be harvested young and eaten as roasting ears.

Most commonly, though, its ornamental ears are allowed to dry so that the kernels may be ground into cornmeal.

In the past, this grain corn was sustenance to communities in the Texas Hill Country. Victory Seed Company founder Mike Dunton says word about the variety came to him back in 20015 when he was approached by C. B. "Hoppy" Hopkins of Fredericksburg, Texas.

According to Hopkins, German settlers entered the Texas Hill country in the mid 19th Century and signed a treaty with Native Americans in the area in 1847. At about that time, the Comanches gave the corn to the Pe…
