Seeds That Need Light to Germinate

Many gardeners are unaware that some seeds require light to germinate and covering them with soil will inhibit their sprouting.It's a good idea to follow these recommendations because a seed that is planted too deeply might not have enough stored energy to push itself above the soil line.Some seeds need the stimulus of light hitting them before they will break dormancy and start to germinate.These plants, such as balloon flower (Platycodon grandiflorus) and poppies, drop their seeds on the soil and they germinate where they land.If these seeds are covered in soil, chances are they will remain dormant and not sprout until conditions improve.While most plants that self-sow in your garden are able to germinate without being covered with soil, that doesn't necessarily mean they absolutely need light.Some plant seeds are indifferent to light exposure and simply need to make contact with soil, whether it is underneath them or covering them.Flowers such as alyssum and cosmos will self-seed during their current growing season as well as the next one, whether or not they are exposed to light.Although the seeds listed above do not require a covering a soil, you will probably get better germination if you follow the recommended planting depth because it will be easier for you to keep them moist and safe from hungry birds.Being able to sow seeds on the surface of soil makes planting easier, but keeping them moist until germination can be difficult since they are exposed to more than just light.Vermiculite is porous enough to let the light shine through while retaining enough water to stay in place and keep the seeds and soil under it moist.It can usually be found near seed-starting supplies; look for finely ground horticultural vermiculite, as other types are not suitable for gardening.And remember, seeds have been sprouting for millennia without a lot of fuss––it's just nice to give them the best chance possible by providing them optimal conditions so they can thrive. .
