Succession planting works by staggering the sowing or transplanting of crops at different times to extend the harvest period and maximize yield. The idea behind this method is to avoid a large glut of produce all at once and instead have smaller, more manageable amounts available over an extended period. This helps prevent waste and ensures a steady supply of fresh vegetables throughout the growing season. By strategic timing and carefully planning the planting schedule, gardeners can optimize space and take advantage of different weather conditions to grow multiple crops successively.
