It is convenient to sow seeds in round holes that are easier to take root.

The size is right and the depth is moderate.

1. Appropriate size: According to the size and growth requirements of the seeds, choose holes with appropriate size, and the diameter of the holes is slightly larger than the diameter of the seeds, so that the seeds can be easily put in and have enough space to grow.

2. Moderate depth: The depth of potholes is also important. For small seeds, the depth can be shallow, while for large seeds or plants that need deeper roots, the potholes can be deepened appropriately.
