nology Network confirms that many spring events across the world are occurring earlier, and fall events are happening later than in the past. However, not all species and regions are changing at the same rate, creating instability in ecosystems. Unpredictability can thwart even the most fervent grower. “The most frustrating thing from the gardener’s point of view is the tremendous variability,” said Mark D. Schwartz, Distinguished Professor of Geography at the University of Wisconsin-Milwaukee. “Things are warmer in general, but that still doesn’t tell you what’s going to happen in a particular year, nor in a specific place.” WHAT’S A GARDENER TO DO? “We’re the first generation of gardeners who can’t rely on the historic weather record to tell us when to plant, what to plant or how to grow it,” said David W. Wolfe, Professor of Plant and Soil Ecology at Cornell University. He’s optimistic about the role that gardeners can play in successful climate adaptation. “Gardeners can be at the forefront of illustrating how we adapt and cope with climate change and reduce our carbon footprint in the process.” Wolfe emphasizes the importance of maintaining biodiversity and good ecosystem services. In the garden or natural landscape, it’s essential that what we grow holds soil in place while maintaining good soil and water quality. The way we grow those plants minimizes impact on the environment. PROS AND CONS: THE NEWS ISN’T ALL BAD Gardeners are naturally inventive and optimistic. Changes in their planting practices and buying choices are already influencing trends. GWA member Nan Sterman, a green industry professional based in Southern California, is seeing an upside to the water regulations and mandated restrictions there. “What people want in their gardens is usually an emulation of what they see in their surroundings,” she said. As beautiful, water-wise landscapes become more prevalent in neighborhoods and public spaces, people are incorporating these concepts into their surroundings. “Nurseries are offering more drought-tolerant plants, including California natives, succulents and Australian natives, which are well adapted to the Mediterranean climate and blend harmo- niously with the local terrain,” she said. Favorable aspects of expanded frost intervals, adding as many as six to 20 more days of growing time across the U.S., increase the potential for crop and vegetable yields. Nimble gardeners, prepared for an early spring, might experiment with new and exciting species, or perhaps grow four plantings of radishes instead of three. Imagine the benefits to air quality if trees were able to grow longer and produce more leaves each year. Warmer gr
