Does my sunflower need repotted?
I planted the sunflower seeds on August 15, 2014, two of them germinated. I initially grew them in a paper cup and moved to this clay pot shown in the photo. This is my first time growing sunflower or any plant and I got the seeds for edible purposes from a nature and health store thinking with the intention of experimenting on growing the seeds.
The current clay pot show in the photo is about half a foot wide and I have placed a 12" ruler for estimation of scale on it. The plant height is 1'4" currently.
I water it once daily at noon with about 140ml of water. No fertilising. Occasional green tea water, perhaps due to the experimental notion. :)
I have read that sunflowers do not react well to replanting and I also read that sunflowers when grown in smaller pots (as opposed to in the ground directly) they tend to stay at a shorter height, which I planned. Furthermore as I got the seeds for edible purposes I have no idea about the type of the sunflower plant weather they are dwarf type or giant.
Any suggestion will be much appreciated.
