Which statement about seed starting media is true?

• A. Should contain freshly dug garden soil for proper nutrition
• B. Must not be allowed to dry out once germination begins
• C. Should have high fertility levels
• D. Should be tightly packed around seeds to force out any air

Answer: (B)

The key idea is moisture management during seed germination. Seeds need water to wake up and activate the enzymes that start growth. Once germination has begun, a steady, even supply of moisture keeps the seedling’s roots able to take up water and nutrients and supports ongoing growth. If the growing medium dries out at this stage, the young plant can’t absorb water, tissues can desiccate, and germination or seedling development may fail. Keeping the medium consistently moist but not waterlogged is essential for a successful start. Fresh garden soil isn’t ideal for starting seeds because it can harbor weeds, pests, and pathogens, and its texture and nutrient levels are unpredictable. Seed-starting media are usually light, sterile or clean, well-drained mixes with low to moderate nutrients so seedlings aren’t burned early on and have room to grow as they are transplanted. High fertility in the starting mix isn’t desirable for delicate seedlings, and seeds don’t need to be packed tightly—air around the seeds and developing roots is important for healthy germination and root growth.
