We go through a lot of jars at Wild Rose, which means we go through a lot of jar boxes! Jar boxes are typically small with corrugated partitions to protect jars during shipping. These boxes aren't very useful for storage or garden mulch, so we've started using them for seedlings. We save all of our jar boxes through the busy Winter shopping season for our Spring seedlings, leaving the partitions in place to prevent neighboring seedlings from intertwining their roots.
The boxes degrade quickly, so we simply start our seeds in them before potting up. The seedling above are tomatoes that are just about ready to be transplanted to larger pots. The spent seedling boxes are then composted with the rest of our household/workshop plant waste.
