What to Plant & Do Right Now
As we enter the final weeks of summer, specific timing is crucial for maximizing harvests and preparing for autumn.
- Texas/Southern Regions: Neil Sperry notes that mid-to-late August is the "last call" for seeding bermudagrass, as it requires specific conditions to establish before winter.
- Fall Vegetable Sowing: In South Carolina, the focus is shifting to planting vegetables for fall harvests while simultaneously protecting landscapes from extreme heat.
- Micro-climate Utilization: Gardeners are advised to use climbing plants like cucumbers and melons to create shade, effectively extending the growing season for heat-sensitive crops like bok choy into late August and early September.
