If you’re an enthusiastic gardener, you may be trying your hand at starting seeds in an egg carton. However, many growers face challenges such as high seedling mortality when employing this technique. To understand this issue better, we consulted several industry experts who shared their insights on why seedlings don't thrive and how to remedy the situation.

Mary Green, a horticulturist with over 15 years of experience, emphasizes the importance of drainage. “Egg cartons can retain a lot of moisture, leading to waterlogged soil and root rot,” she explains. “Be sure to poke holes in the bottom of the carton to allow excess water to escape.
Soil quality is another critical factor. According to John Miller, a soil scientist, using the right potting mix is vital for seedling development. “Standard garden soil is too heavy for seed starting in an egg carton. A light potting mix specifically formulated for seed starting can improve germination rates and overall health,” he advises.
One of the most frequently overlooked aspects of seedling care is the light conditions. Jane Adams, an indoor gardening expert, notes, “Many gardeners underestimate how much light their seedlings need. If they don’t receive sufficient light, they will become leggy and weak. Place your egg carton in a bright location or invest in grow lights to provide the necessary intensity.”
Temperature is also a crucial player in seed germination. “Different seeds require different temperature ranges for optimal germination,” says Dr. Lisa Brown, a plant physiologist. “Ensure your egg cartons are kept in a warm spot—ideally around 65°F to 75°F—to help your seedlings thrive.”
Nutrition is key to strong seedlings. David Zhang, an agronomist, suggests fertilizing your seedlings after they develop their first true leaves. “Using a diluted liquid fertilizer can provide the necessary nutrients your seedlings need to grow robustly,” he recommends. “However, don’t overdo it; too much fertilizer can lead to chemical burn.”
Lastly, timing and patience can make a world of difference when starting seeds in an egg carton. “Don’t rush the process,” advises Sarah Johnson, a gardening coach. “Some seedlings naturally take longer to sprout than others. Monitor their progress but give them the time they need.”
Starting seeds in an egg carton can be a fun and cost-effective way to begin your gardening journey. By addressing factors such as drainage, soil quality, lighting, temperature, and nutrition, you can significantly reduce seedling mortality rates. Incorporating these expert suggestions will help ensure your seed-starting efforts are met with success in the spring garden.
