West Virginia’s variable weather can catch gardeners off guard, leading to late frost or unanticipated heat waves. Utilizing row covers can help protect Swiss chard from unexpected climate shifts, especially when transitioning into warmer seasons.
Failing to rotate crops is a frequent mistake in West Virginia. Since Swiss chard is closely related to beets, be sure to practice crop rotation to prevent disease buildup and ensure healthier plants for seasons to come.
