When a heat wave sends temperatures soaring into the 90°F to 100°F range, even experienced gardeners can make mistakes that leave vegetables stressed, unproductive, or permanently damaged. Ironically, many of these mistakes come from trying to help plants survive the heat. The good news is that most heat-related problems are preventable. Understanding how vegetables respond…
When the weather forecast predicts several days of 95°F to 100°F temperatures, most gardeners think about watering, mulching, and shade cloth. But there’s another important task that can protect your harvest: knowing what to pick before the heat arrives—and what to leave on the plant. Harvesting at the right time reduces stress on vegetable plants,…
Tomatoes and peppers love warm weather, but even these heat-loving vegetables have their limits. When daytime temperatures climb above 90°F to 95°F, and especially when warm nights remain above 70°F, plants begin to experience heat stress. Flowers fall without setting fruit, tomatoes develop pale, leathery patches from sunscald, peppers stop growing, and harvests slow dramatically….
When temperatures climb above 90°F and stay there for several days, watering becomes the single most important job in the vegetable garden. Water too little, and plants wilt, flowers drop, and harvests decline. Water too much, and you risk shallow roots, nutrient loss, and disease. The goal during a heat wave isn’t simply to water…
Every summer, vegetable gardeners ask the same question: “My plants look healthy, so why did they stop producing?” If daytime temperatures consistently climb above 90°F to 95°F, many vegetables temporarily stop flowering, setting fruit, or producing new growth. This is a normal survival response—not necessarily a sign that something is wrong with your garden. The…
Hot weather alone can challenge a vegetable garden. Add high humidity, and plants face an entirely different set of problems. While gardeners often focus on temperature, humidity plays an equally important role in determining how well vegetables grow, flower, and produce. High temperatures combined with humid air can slow plant cooling, encourage diseases, interfere with…
