I lost a whole row of lettuce last spring because I buried the seeds like they were beans. Nothing came up, and I assumed the seed was old. It wasn’t until later that I learned lettuce needs light to germinate.

This time I checked the planting depth calculator on Gardenvoila before sowing carrots, lettuce, and a few bulbs, and germination was noticeably better. Seed packets don’t always list depth clearly, especially for older leftover seed. I also learned bulbs go deeper than I’d been planting them.

Which crops give you the most trouble with depth? I’m still unsure about heavy clay and whether to plant a bit shallower there. Any tips for tiny seeds like carrots, which seem to wash out with every watering?
