What happened when the cherry tomato seeds (small tomatoes) I bought were planted in a flowerpot for two weeks without sprouting? I live in Wuhan, where the temperature is nearly 20 degrees.

The temperature is still a little low. Generally, it germinates quickly around 22 degrees. If the temperature and humidity are suitable, the quality of the seeds will be fine, and they will germinate in a week or so.
