My site is very wet waterlogged clay soil, prone to flooding, surrounded by fields with rushes. There is an exposed site directly in front of the house about 20 feet away. What trees or shrubs would you recommend that would act as a barrier/shelter without growing too high? The site is surrounded by ditches and mature ash trees.

Is the green holly, Ilex aquifolium, male or female?

I was thinking of planting about 15 or so wych elm trees along a wall in a field. I heard that they are less prone to attack by Dutch elm disease than other elms but I was still wondering if it is a good idea to plant them. Is there another type of elm that's not prone to Dutch elm disease? If it is safe to plant them how far apart should I space them? What type of soil suits the elm?

A friend wants to grow Goji berries & I remember hearing or reading something about the plant bringing blight into the garden if grown with or near potatoes but I cant actually recall the correct info.
