Day# 44, a look at extreme plant sizes

An example of the extreme size difference among Pima cotton plants.

This is the small Pima from above photo set. The cotyledons ragged state is fairly common among all species. The first true leaf can be seen in the center of the photo pointing at about 1:00 o’clock, and the second is pointing at about 4:00 o’clock.

The Upland cotton plants also have a range of sizes. The small one has one set of several true leaves developing on the right side, the left side foliage is a cotyledon.

Below is a view of the larger Upland’s cotyledon node, something is starting to develop at this point on both sides of the stem at this point. growth on the stem’s right side is visible.

In the last post, a mention was made about mosaic on the Upland cotton leaves. This photo shows a new leaf, and one afflicted to the right. The new leaf does not show any sign of this impairment, nor do any of the newer leaves of this species.

The Upland’s leaf shape is starting to become more defined.

The Turquoise-dyed cotton seed’s second true leaf withered this week, and the first true leaf does not look healthy. The stem appears sound.

Several details of my project have not been explained. Hopefully, this will fill in some blanks. Said undertaking is being attempted at the north end of the Willamette Valley in Beaverton. A frost can be expected through the second week in May, Day# 72 of this undertaking. These plants are living in an east-facing window, they are also sharing space with tomato, basil, and dill starts. There is a lot of competition for limited light. The sever-day weather forecast is being carefully watched. By moving outside, the plants would be getting more sunlight, and cooler weather. These plant will eventually be put into 10+” pots, the large ones that can be found at Dollar Tree. There are several reasons for keeping the cotton plants in pots. Cotton is a perennial. Based on my on-line reading, a commercial cotton plant is about 30-36” high, approximately the size of an average tomato plant,. The catch is that a cotton plant this size can easily have a tap root 10-12 feet deep. Our frost line is about 15-18”, so there is a chance this plant could reemerge, and perhaps spread, the spreading part is my hunch, nothing to back this thought. A pot of colocasia bulbs were left out last winter, and most were in fine shape this spring. If a tropical plant’s bulb can survive an Oregon winter, the same may be true for a cotton plant.

Thank you all for your visits to Oregoncotton. Please remember I have never grown cotton, and my educational background and work experience is not related to agriculture.
