Getting disappointed when planting zinnia from seed.
Okay, first of all, I live in a tropical country, the Philippines. I have seen zinnia grow here very well. I get really disappointed while planting zinnias by seed because they grow so lanky, and so feeble.
When I grow them, I just basically put some soil in the pot, put the seeds, and then lightly cover the seeds, then I water. But after a few weeks, they grow too high but too lanky and then they just basically lie down and eventually die from i dont really know what.
Could someone please help me? What am I doing wrong and how can i make these zinnia seeds grow and become flowering plants? :(
