Choosing a packet size
- The 500-seed packet suits home gardeners and small beds wanting several successions or a steady supply for salads. It’s also great for container troughs and compact raised beds in spring and fall.
- The 5,000-seed packet is ideal for larger gardens, community plots, or small market growers planning continuous sowings. It provides ample seed for baby-leaf rows and staggered plantings across the cool season.
- The 15,000-seed packet is best for market growers, CSAs, and landscapers establishing long beds or high-tunnel plantings. Choose this size for baby-leaf production, wholesale bunching, and broad seasonal successions.
