📏 THE PLANTING DEPTH RULE
🌱 YOUR DEPTH RULE CHECKLIST
Seeds carry a small lunchbox of stored energy. If planted too deep, a sprout can run out before reaching sunlight. If planted too shallow, roots may dry out. The 2x width rule gives most seeds a safe starting point.
- 🌰 Sort by size: tiny, medium, and large seeds need different depths
- 📏 Quick rule: sow each seed about twice as deep as it is wide
- 🖐️ Fine-textured soil: loose top layer helps shoots push upward
- 💧 Gentle watering: mist or light can so seeds stay in place
- 🏷️ Label each row: include crop name and sowing date
- 👀 Daily checks: watch for crusted soil and keep moisture steady
Time: 10 minutes to set up a tray · Better emergence rates · Fewer weak seedlings
PAGE 1 OF 5, WHY DEPTH MATTERS
START SMART
SEEDS HAVE LIMITED FUEL
A seed is like a tiny battery packed with startup energy. That energy powers the first root and first shoot before true leaves can collect sunlight. If you bury the seed too deep, the shoot must travel too far and may stall underground. If you leave it too close to the surface, heat and dry air can stop germination. The planting depth rule keeps the trip short enough for success and deep enough for protection.
⚡ DID YOU KNOW?
Many seed packets print a depth range. The 2x width rule is a strong default when the packet is missing or hard to read.

TOO DEEP
🕳️ Long climb drains seed energy.
😓 Weak sprouts fail below soil.

TOO SHALLOW
🌬️ Top layer dries quickly in sun.
