April is one of the most productive planting months for Spartanburg County gardeners in USDA Hardiness Zone 8a.
With the last average frost date now behind us, warm-season vegetables can go directly into garden beds. Tomatoes, peppers, squash, cucumbers, beans, and corn are all safe to plant now. For herbs, basil, dill, and cilantro thrive when planted in mid-April.
Ornamental plantings can also begin in earnest. Crepe myrtles, knockout roses, lantana, and zinnias all do well when planted this month in the Upstate. Mulching new plantings with 2 to 3 inches of hardwood mulch helps retain moisture during the warm, dry conditions forecast for this week.
The Clemson Cooperative Extension office in Spartanburg County is a resource for soil testing and planting calendars specific to the Upstate. The Spartanburg County Extension office can be reached at 864-596-2993.
With highs reaching the mid-80s this week and unusually dry conditions in the forecast, new plantings will need consistent watering until established.
