Key ideas in How to Grow a Plant
- A seed holds a tiny living plant that is resting inside
- The hard seed coat protects the inside from drying out or getting damaged
- The food supply inside fuels initial growth before the plant can make its own food in sunlight
- Moisture softens the hard seed coat so the baby plant can break out
- Warmth signals to the seed that the season is right for growing
- Seeds do not need sunlight to germinate, only moisture and warmth
- Seeds should be planted about 2 to 3 times as deep as their width
- Burying a tiny seed too deep exhausts its stored food before the sprout reaches the surface
- Big seeds have larger food stores to push up through deeper soil
- Seeds need good contact with damp soil particles to absorb moisture
- Stamping or packing dirt tightly squeezes out air pockets that roots need to breathe
- A gentle pat with fingertips provides firm contact while keeping the soil fluffy
- A clear cover traps evaporating water vapor so the soil surface doesn't dry out
- Trapping moisture creates greenhouse-like humidity that helps seeds crack open
- The cover must come off as soon as green sprouts emerge to let fresh air circulate and prevent mold
- Green leaves absorb sunlight like solar panels
