How do you speed up seed germination?

One easy way to make seeds germinate faster is to presoak them for 24 hours in a shallow container filled with hot tap water.

What happens if seeds are planted too deep?

ANSWER: Seeds that are planted too deep in the soil may grow into weak, feeble seedlings or fail to germinate at all. If it's been buried too far under the surface of the soil, the seed may not get the light it requires to sprout.

Does hydrogen peroxide help seed germination?

Hydrogen peroxide is thought to increase germination rates by breaking down the seed coat, thus allowing the seed to take in more oxygen.
