Lavender fails more often from wet roots than from cold, which is why drainage matters more than almost anything else when choosing a spot or a variety. Gardeners in the coldest zones still have options: our guide to growing lavender in zone 3 and the companion guide to zone 4 lavender cover hardy varieties and planting dates that hold up through harsh winters, provided the roots stay dry.Heat brings its own problems, and lavender struggles in ways gardeners do not always expect once summers turn humid rather than dry, which rules out some popular varieties in the hottest zones. Support matters too as plants mature, since a floppy, woody lavender benefits from the right trellis rather than staking it upright by hand. Harvest timing affects how well cut stems hold their scent and color once dried, and picking at the right bud stage makes the difference between sachets that last for years and ones that fade within a season. The guides below cover 55 lavender articles, sorted by zone, variety, and the pruning and harvesting tasks that keep plants compact for years instead of leggy after one season.
