| How does the depth of a radish seed effect the germination rate and what is the optimal depth? |
| If a seed is planted too deeply, it will run out of stored energy before the sprout can reach the sunlight. Since sunlight on the leaves helps the plant manufacture food, the seed has only enough energy to send the sprout a pre-determined distance and unfurl the leaves, before it runs out of stored energy. This applies to all seeds. A general rule of thumb is to plant a seed no deeper than two or three times the seeds diameter. |
