My Cotton Is Trying To Produce A 2nd Harvest

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.

Io Moth Caterpillar – ouch

I walked and drove past this Mulberry tree for a week or so, while going up and down my driveway, and noticed massive leaf loss.  I didn’t immediately do anything about it because I figured that it was the usual fall grasshopper destruction.  On my way down to the mailbox by the road, I decided to walk over to the 7 foot, second year Mulberry tree and check it out.  I was very surprised to see about 14 giant, green, prickly caterpillars. These things were about 4″ long. They were covered with rows of bur looking things that turned out to be toxic stingers.

I was not prepared to remove these pests – I did not have my leather gloves my pocket so I tried to flick one off with my finger. Ouch. I only knocked the critter half way off but received a very severe sting. I had to find a stick to finish knocking off the other caterpillars.

I had expected fire ants to be the first predators to arrive on these dead caterpillars, but it yellow jackets were there first.

Doing some research to find out what these giant stinging caterpillars are, I found that there are public health warnings out about them. My sting could have resulted in a serious allergic reaction. The burs are hollow, poisonous hairs that are connected to underlying poison glands. The resulting allergic reaction could last a day or 2, with possible nausea for the first few hours.

The “Automeris io” moth caterpillar has long rows of tubercles armed with green and black spines. This thing is classified as a “Urticating” caterpillar. They have urticating hairs or bristles, meaning ‘irritating hair’. They are a defense mechanism, like a nettle plant’s hairs. The immature stages of several species of moths in states east of the Rocky Mountains are venomous to humans because of their external poisonous spines and hairs.

While looking at the tree to find all of the caterpillars, I found a round, clay, vase like structure with a hole in it. I have seen these on other plants around the yard. They are obviously some sort of bug home.
