Do seeds need light to germinate in paper towel?

Paper towels, filter paper or even newspaper provides an excellent medium for germinating seeds. Place the paper with seeds inside and reseal the bag. Set the bag anywhere out of direct sunlight that stays at room temperature. The bag acts like a miniature greenhouse that retains heat and moisture.

Can you germinate seeds in the dark?

Most seeds germinate best when they’re placed in the dark. The presence of light, which is crucial to seedling development, may actually stunt the process of germination.

Will seed sprout without sunlight?

Some seeds don’t need light to break through their seed casings and sprout. Most seeds germinate best with controlled amounts of UV generation, but there are seeds that germinate in the absence of light. Furthermore, there are plants that get enough just light in highly shady areas of a garden or even in darkness.

Should seeds be kept in the dark?

• Calendula.

• Delphinium.

Why do seeds germinate better in the dark?

The light slows stem elongation through hormones that are sent down the stem from the tip of the stem. In the darkness, the hormones do not slow stem elongation. The seeds in the dark-grown condition rely upon the stored chemical energy within their cells (lipids, proteins, carbohydrates) to power their growth.

How do we know that seeds do not need light to germinate?

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.
