From vegetables to landscape plants, this guide will explore what can be successfully planted in August across various USDA zones in Texas, ensuring your gardens thrive despite the state’s challenging climate.
Vegetables To Plant
Planting in August can be a rewarding experience, especially for cool-season vegetables that thrive as temperatures start to cool down slightly. Here’s a comprehensive look at vegetables suited for August planting across Texas.
Okra
Temperature Tolerance: 80-100°F
Okra, a true Southern staple, thrives well in the heat of August. It’s ideally planted in the warm USDA zones 8-10 during this month. Given its drought tolerance, Okra requires full sun and can handle the high temperatures often present in Texas. Plant seeds directly in well-drained soil about 1 inch deep. For continuous harvests, you can stagger planting every few weeks until the weather cools.
Radishes
Temperature Tolerance: 40-85°F
Radishes are remarkably quick to mature, making them ideal for late summer planting. In USDA zones 8-10, sowing seeds directly into loose soil will yield a harvest ready to harvest in just three to four weeks. Radishes thrive in cooler weather, so by the end of August, they can benefit from the slight drop in temperature. Consider planting varieties like Cherry Belle or French Breakfast for a mix of colors and flavors.
Spinach
Temperature Tolerance: 50-75°F
August is a perfect time to plant spinach in USDA zones 7-10. This cool-season leafy green thrives best as temperatures begin to decline. Directly sow seeds about ½ inch deep into well-prepared soil. Spinach germinates easily and can be harvested in about 40 to 50 days, making it an efficient choice for gardeners looking to maximize yield before winter.
Carrots
Temperature Tolerance: 45-75°F
Carrots are ideally planted in Texas during the latter part of August. In zones 7-9, the heat of late summer drops to a manageable level for germination. Plant carrot seeds about 1/4 inch deep in loose, sandy soil to encourage long, straight roots. Depending on the variety, harvest can be enjoyed anywhere between 70 to 80 days after planting.
Beets
Temperature Tolerance: 50-85°F
Planting beets in August takes advantage of the gradual cooling trend. These nutritious roots excel in USDA zones 7-9. Directly sow beet seeds 1 inch apart in well-drained soil, as they require a little space to grow properly. Beets grow well in moderate temperatures and can mature in about 50 to 60 days, ideal for fall harvests.
Cucumbers
Temperature Tolerance: 65-95°F
If the heat doesn’t subside completely in August, cucumbers still have a chance to thrive in the Southern climate. Planting seeds in zones 8-10 can yield results in quick succession. Make sure the soil is warm and well-drained, and plant seeds about 1 inch deep. Cucumbers grow rapidly and can be ready to harvest in under two months.
Swiss Chard
Temperature Tolerance: 50-85°F
Swiss chard is an excellent choice for an August planting, particularly in the warmer regions of Texas (zones 8-10). It is particularly hardy and will withstand some heat. Sow seeds directly into your garden about 1 inch apart, and once they germinate, thin out to ensure ample growing space. Swiss chard can be harvested in as little as 50 days and thrives in cooler fall temperatures.
Green Beans
Temperature Tolerance: 60-90°F
Green beans (particularly bush varieties) can be planted in August in USDA zones 7-10. They prefer warm soil but are relatively quick-growing. Seeds should be sown 1-1.5 inches deep in rows spaced about 18 inches apart. Harvest is possible in just 50 to 60 days, giving you ample time to enjoy them before the frost arrives.
Peas
Temperature Tolerance: 40-75°F
Mid to late August is an excellent time to plant peas in Texas, particularly in USDA zones 7-9 before the truly cold weather sets in. Plant seeds about 1 inch deep in well-drained soil. Peas prefer cooler temperatures, so late summer planting allows them to thrive. They typically mature in 60-70 days, yielding delicious pods well into the fall months.
Collard Greens
Temperature Tolerance: 50-85°F
Collard greens are a hardy green that can be seeded in August across USDA zones 7-10. They thrive with cooler temperatures and humidity. Collards can be directly seeded about 1 inch apart, with a harvest time of 60-75 days. Their flavor improves after the first frost, making them an ideal selection for fall planting.
