Should you soak seeds before planting?

Soaking seeds before planting helps you to break down the seed's natural defenses against what it expects from Mother Nature, which then allows it to germinate faster. Another reason is that while Mother Nature actively assaults seeds, she also gave those seeds an internal gauge to help them know when they should grow.

What is the longest lasting seed?

A Russian team discovered a seed cache of Silene stenophylla, a flowering plant native to Siberia, that had been buried by an Ice Age squirrel near the banks of the Kolyma River (map). Radiocarbon dating confirmed that the seeds were 32,000 years old.

How do I know if a seed is viable?

Water test: Take your seeds and put them in a container of water. Let them sit for about 15 minutes. Then if the seeds sink, they are still viable; if they float, they most likely will not sprout.

  3. Sow before weeds emerge.
