Growing plants from seeds is often difficult because pests and others may eat the seeds.
Since birds are eating the seeds kept outside the house in the balcony , the seeds were put in a plastic container and soaked in water.
For the first few days,the seeds remained in the plastic container.
After a few days, the seeds have completely disappeared, there is no trace at all. In future,the container with the seeds should be covered to prevent loss of seeds.
