For most plants, the general rule is to plant them at the same depth as they were in their pots. But, some plants are rebels and need to be planted deeper or shallower. Like tomatoes, which need to be planted up to their first true leaves to develop strong stems.
And then there are the bulbs - like tulips and daffodils - which need to be planted three times deeper than their height. Yep, it's like they're trying to escape the world above and grow in secret!
But, what about seeds? They need to be planted at a depth that's two to three times their width. It's like they're tiny little spies trying to sneak up on the world above - they need a little cover to get started!
