As heatwaves become more frequent across much of the US, it's easy to assume every plant in the yard needs extra water. In reality, many established perennials, native plants, and drought-tolerant shrubs are surprisingly resilient. Others, however, can quickly become stressed during periods of extreme heat, showing signs of wilting, scorched leaves, and reduced flowering, making it important to know exactly when and where to water plants.
The key is knowing which plants are most vulnerable and stepping in before they begin to struggle. From thirsty hydrangeas in the South to sun-baked containers on patios and decks, these are the plants worth checking first during a heatwave, and how to keep them looking their best. If you're wondering which plants to water in June as temperatures climb, these are the varieties to prioritize.
