Winter Seed Sowing Tip: How Deep Should You Sow Your Seeds?
You already the importance of moisture in seed germination, if you listened to our last DIY episode, 182.
But, you might not know the important role of seed sowing depth for the best germination.
Since your whole goal when sowing seeds is to get them to germinate and be healthy plants, you need to know how deep to sow them.
Plus, you don't want to waste the seed, your time, or your hard-earned money by sowing seeds the wrong way, so let's go over how to do it.
The general rule is, the larger your seed the deeper or more soil covering it needs.
The reverse is true, too, where the smaller your seed the shallower it needs to be placed.
Some really small seeds barely need to be covered at all or can lay on top of the soil.
Since seed sizes are different between, say lettuce, onions, tomato, and even snap dragons, you need to sow each plants seeds according to what depth they actually need.
A general sowing depth applied to ALL seeds is going to result in some seeds germinating and others not at all.
That's wasteful, so don't do it.

Here are seed sowing depths for some popular plants:
-
Lettuce: cover an 1/8th of an inch
