A few weeks ago I bought a sunflower plant, the ones sold in big hardware stores with one flower that come in a 6" pot. So I moved it to a bigger 12" round pot the day after buying it.
As of today, the flowers have died and the leaves are greenish-brown. Im no expert, but they're not doing well. A small one started to grow , but it's all brown.
I water them every day, but it doesnt seem to help. I live in the Caribbean and they're in my rooftop with very little shade. In terms of temperature, we get 85 to 90-degree heat everyday, so it's horribly hot.
So what can I do? Could it be that it's too hot even for the sunflower?
