so I bought some Agerato nano seeds and it's been 5 days and they have yet to sprout. I planted some zinnia liliput in the same big pot and the seeds sprouted well. What should I do?
Ageratum seeds take a bit longer to germinate than 5 days. In my experience, they need at least 7-10 days. Also, make sure your ageratum planting is between 24-27C which is warmer than typical room temp, yet is also the temperature they require to sprout.
