I bought some green heirloom cotton seeds from Southern Exposure seeds. I have been growing a half dozen or so plants for a few years, just collecting the cotton for the time being.
I planted the plants – this year from last year’s seeds – in the spring and the cotton was ready to harvest by late summer. I decided to just leave the plants in the ground after harvest. I then noticed that the plants put on new leaves and then new buds. I let them grow. By late fall and cold weather, the plants had put out flowers and then the baby bolls developed. Unfortunately the 2nd wave of buds could not mature before the killings frosts arrived. I am in zone 8. If I was a zone or 2 warmer, these plants would have probably produced a harvestable 2nd round.
This plant has a 2nd round bloom on a plant with a harvested cotton shell noted by the hand.
These re-blooms came in two colors – pinkish/light lavenderish and yellow.
The catalog said that these plants grow to about 5 feet. Mine, in a raised bed with less than 12″ of soil on top of red clay ground, and planted about 12″ apart, grew to about 28 or so inches. The catalog says that they should be planted 18-30″ apart in rows 5 ft. apart. I don’t have that kind of room, in fact, I don’t have any on-ground growing space because of our red clay soil. I am running the risk damaging the genetic quality of my seeds by growing them in less than ideal conditions. I am considering maybe planting one plant at the end of some of my beds, hoping that maybe a plant by itself may have more root room in my tightly packed beds.
