Do cottenless Cottonwood shed cotton after 7 to 10 years or are they always cottonless?
Rate This FAQ
Male clones of cottonwoods should not produce cotton- only the female trees produce the seeds ("cotton").
Sometimes you will hear of cottonless cottonwood trees later developing cotton but they were probably mislabeled.
Some hybrid cottonwoods sold are listed as "sterile female hybrids." These are not cottonless because they are not male. The "sterile" refers to the fact that the seeds they produce are incapable of germinating. However, they still produce the cotton to distribute the seed.
If you have a cottonwood that produces cotton and you don't want to cut it down, you can use Florel to prevent cotton development in female trees. You will need to check the label to see when to apply it.

- I have an apricot tree that is so heavy laden with fruit that it broke a major branch yesterday leaving me with about a half bushel of partially ripened fruit. Can any of it be saved? What should I do?
- I planted a Chanticleer pear tree about two weeks ago (mid June) in Perry. I watered it everyday for about 5-6 days and have since cut back to 1-2 times per week. Many of the leaves are very dry and crumble when squeezed. Have I been over watering or under watering my tree? How often should I water it or is it already too late for my tree?
- We would like to plant a pasture (about 2 acres). We would like one that creates sod, like a lawn, rather than a bunch grass. It will be used to hold a hillside and eventually to graze a few animals. We could cut it for grass hay also. What would be the best varieties of seed to use for a pasture like this?
- Two years ago I moved into a house that has a large apricot tree in the backyard. Last year was our first apricot harvest. The apricots got large a ripe, and looked great. But when I picked one and tasted it, is was VERY mushy and bland. Upon further investigation, all the fruit was this way. Does this mean that the tree is too old or maybe just a bad tree? I don't want to deal with the hassle of a fruit tree if I can't use the fruit.
- I have an older crab apple tree that is focal point of my small yard. About 3 years ago the leaves became infected with powdery mildew. I have been told to not do anything with this, as it will eventually go away and the tree will fine - but over the years it has gotten much worse each spring. There are only about 60% of the leaves that are starting to look healthy by mid-June. Over all, the leaves are withered and this year we have very few blossoms. Another problem: The tree also has four large limbs that come out of the trunk. I noticed that there seemed to be wood pulp inside a place where a branch was cut off years ago. I scooped out the pulp and found that some bug or other creature has created a cavity that goes 6” into the 10-12” diameter limb and a large man’s fist could easily fit into the hole that has been created. While inspecting the hole I discovered a ¼” or so hole in the very back of the cavity, but no sign of the culprit. The limb seems to be doing fine, as the leaves on the branches from this limb are in no better or worse shape than the rest of the tree. I had my tree pruned by a highly recommended person this spring, in hopes that this would help with my powdery mildew problem. I love my tree, what should I do next about my perpetual powdery mildew problem and the unknown culprit who is dinning on my tree limb?
- Please Help, my blue lake pole beans are not producing like they should, the blossoms are not sticking and those that do have matured into flat stringing beans or Big hard ones with white fuzz around the middle of the seed inside please help me I need my beans.
- My petunias are horribly sticky - I assume thrips are in control although I have tried to keep them washed off (insecticidal soap) and sprayed with a systemic (orthonex). Is there anything else I might try? Would a dormant oil spray work, and if so when would I use it? Also, there are small worms that are probably chomping the blossoms. What would work to prevent or kill them? How do worms can get into my flower boxes, that are at least 6 feet off the ground?
- I have successfully grown summer squash for many years, but this year the newer leaves on the plants (sunburst hybrid) are wilting and dying, despite (or because of?) the cool wet June weather we are experiencing. The more mature leaves seem to be okay. I cut one of the leaves off at its base and didn't see any evidence of insect infestation in the stem or on the leaf. The base of the plant also appears to be free of insect infestation. Do you know what might be causing the problem, can it be treated, or do I need to pull up the plants, and if so, can I put new plants in the same location (the rest of the garden space is already filled)?
