As temperatures surge, professional growers and university extension specialists emphasize that proper species selection and targeted morning watering can prevent widespread garden decay.
Improper watering during heat waves often causes plant stress or root injury.
Key Strategies for Garden Care
Staff members at Hickory Hill Nursery in Forest Hill, Louisiana, altered operational schedules to safeguard workers while managing heat-stressed crops.
Nursery experts advised growers to check soil weight before applying extra water.
Heavy pots indicate the plant is suffering from environmental heat stress rather than dehydration. Lighter containers signal actual water depletion.
University of Missouri Extension horticulture specialist David Trinklein noted that regional adaptation plays a key role in plant survival.

"Large retail outlets may sell plants not suited to their area's extreme temperatures," Trinklein said in a press release.
He added that species imported from cooler European climates frequently fail to thrive under harsh southern or Midwestern summer conditions.
"Just because it looks pretty in the store doesn't guarantee that it will be attractive for long periods of time in a garden," Trinklein said.
To withstand intense heat and humidity, specialists recommend planting resilient annuals and perennials such as vinca, lantana, zinnia, angelonia, and scaevola.
Tropical foliage like caladiums and heat-adapted dwarf cannas also maintain structural integrity under full sun exposure.
Former LSU AgCenter horticulture specialist Dan Gill cautioned that late summer storms present additional risks.
