Choosing a packet size
- A 50-seed packet is ideal for home gardeners, small raised beds, or anyone trialing celeriac. It provides enough seed for one to two sowings or to fill a compact 35–50 sq. ft. bed with proper thinning.
- The 500-seed packet suits larger gardens, community plots, and market growers planning staggered plantings for storage roots. The ample count supports multiple successions, backups for slower germination, and transplant losses.
