Have you ever struggled with starting plants from seeds? Almost all of us have, and it’s absolutely normal. Some seeds fail because they’ve been rendered infertile through improper storage, others fail because they’re grown in the wrong type of soil… and still others fail because they just haven’t gotten enough light to trigger germination.
That might sound weird to those of us who were taught to plant seeds based on the 3x rule: that the seed should be planted at a depth 3 times its own size, and covered lightly with soil. The truth is that there is no true rule of thumb in that regard, and there are many seeds that require direct sunlight to shake them awake and tell them to get growing already. This is especially common for very fine seeds, like certain flowers and herbs, whether culinary or medicinal.
Seeds that Love Light
The following are just a few plant species that require direct sunlight to germinate:
- St. John’s Wort
- Bee Balm
- Savory (winter and summer)
How to Cultivate These Plants
When it comes to sowing seeds for any of these, pre-water the soil in your growing bed, then scatter the seeds loosely overtop it. Then, using the palms of your hands, press those seeds lightly into the surrounding soil so they’re “hugged”, but not buried. If you live in a cooler climate, wait until the hottest, sunniest days of your growing season to plant these, or you may risk losing the majority of them to rot.
Water these regularly, but lightly, making sure you don’t drown them with overzealous flooding. If you’re growing these plants indoors, be sure to keep them in a very sunny spot, and try to keep pets away from your pots so they don’t disrupt the seeds while they establish their rather delicate root systems.
