Just as some plants do better in shady spots, some handle scorching weather in Texas better than others. Wilting could mean a plant is handling the heat okay - or that it needs help.
Plant leaves may droop mid-day, which keeps more of their surface out of direct sunlight and helps keep them cool. This is okay if the leaves perk up once the sun goes down. The same is true when wilting occurs early spring when plants carry a lot of tender new growth. Be concerned when a plant doesn't perk up in the evenings during hot weather or when you see leaf scorching – sun-exposed leaves turning yellow. To avoid weather woes, stick with plants that are native or adapted to your region. Create an open-sided tent over any heat-sensitive plants using a frame and shade material if needed. Mulch also helps insulate a plant's roots from weather extremes.
