I have a black walnut and have recently planted some palm trees near it. Specifically, a Windmill palm. I cannot seem to find out if palms are tolerant to the chemical (Juglone), which black walnuts secrete.
Unfortunately, I am unable to find any surefire proof that these trees can withstand the toxicity of black walnuts. Therefore, I would not recommend planting it anywhere within close proximity of the tree. You can, however, grow the palm in a container or locate it at least 50 feet or more away from the black walnut.

I bought some windmill palms recently and I put them in large pots for their first year before I transplant them to my yard, in CT. I started noticing a white lint-like substance on the leaves (fronds). When I wipe the lint off the leaves, there is a yellow spot on the leaves where the white was. I heard that they could be mealy bugs. I don't see anything living on the plant, just the white stuff. The dots are very small right now.
I heard that the mealy bugs can be eradicated by spraying a mixture of alcohol and water with a tiny bit of dish soap on the leaves. Does anyone know about this plant disease and cure?
It is mealybugs or palm scale. Neem oil is a good treatment. These articles should help: https://www.gardeningknowhow.com/plant-problems/pests/scale-bug-how-to-control-plant-scale.htm
How do I go about covering windmill palm for winter in New Jersey? It is an 8 footer planted in 48 by 48 foot wooden box.
These trees are actually pretty hardy and can take cold fairly well. For extreme winter weather conditions, you may need to cover it. Here is more information: https://www.gardeningknowhow.com/plant-problems/environmental/protect-plants-in-freeze.htm
I have 6 large windmill palms that have flower pods on them. Can I cultivate from them?

Our windmill palm is in a large pot outside. We want to plant it in the ground. We live in North Vancouver, B.C. and the palm would be in a west-facing location. It's been in the large pot for five years and doesn't seem to be growing much at all. It also has three stiff brown stems. I've trimmed the leaves which looked burnt.
Your growing zone is 7b, the Windmill Palm is hardy in zones 8a thru 11.
By the growing zones you are to cold, and remember these are guidelines. Weather trends and other conditions need to be considered.
I think I would repot and refresh the soil. This Palm generally is a slow growing variety.
Here is a link to refresh you on the growing conditions and care needed.
How can you tell which are male from female flowers since they're both yellow colored?
Male trees will produce yellow flowers in a branching form.
These will not produce fruit.
A female tree has flowers that are more of a green color then yellow.
These will produce fruit.
Occasionally a tree will produce both male and female flowers.
The flowers will be more like the male flowers, but larger. These will produce fruit.
I have 4 Windmill palms (sizes 6 ft. and 9 ft. tall) planted around my home this spring. I live in Louisville, KY (in part of Louisville metro- Zip Code: 40205). What is the best way to winterize my Windmill Palms? I plan on doing this in early to mid December.
