Seed Starting Basics: From Sowing to Seedling

Starting Strong

Successful seed starting begins before you ever plant a seed. The foundation is proper timing, quality seed starting media, and consistent conditions.

Seed Starting Mix

Use a light, sterile seed starting mix rather than garden soil. Good options include: - Seed starting mix (peat moss or coco coir based) - Finely sifted compost - Perlite and peat moss blend (1:1)

Garden soil is too heavy and prone to "damping off" fungal diseases. The sterile mix ensures seedlings stay healthy.

Containers

Use any container with drainage holes: - Cell packs and flats - Seed trays - Even cups or newspaper pots - Whatever you have will work fine

Moisture and Humidity

Keep seed starting mix consistently moist but not waterlogged. A dome or plastic cover maintains humidity for germination, but remove it once seedlings emerge to prevent fungal issues.

Water from below by placing containers in a tray of water, letting them wick moisture up. This prevents damping off and keeps seedlings strong.

Light

Once seedlings emerge, they need strong light immediately. Inadequate light causes leggy, weak seedlings. Options: - Fluorescent or LED grow lights 2–3" above seedlings - South-facing windowsill (supplemented with lights if needed) - Keep lights on 14–16 hours daily

Temperature

Most seeds germinate best at 65–75°F. Once seedlings emerge, most prefer cooler temps (65–70°F) to prevent legginess.

Hardening Off

Before transplanting outdoors, gradually acclimate seedlings to outdoor conditions over 7–10 days: - Start with a shaded spot outdoors - Increase sun exposure daily - Gradually reduce watering frequency - This prevents shock and transplant failure

Starting strong means transplanting stronger. Invest in the basics, and you'll be rewarded with vigorous plants.
