    The upright growth habit will likely resume in time as the trees put out new vertical growth from near the heading cuts. As regrowth appears, you can thin the shoots to select the strongest upright leaders. You can also shape back the lateral branches a little to suppress the horizontal growth and favor the upright growth. It may take a year or two for recovery, but Leyland cypress are usually vigorous upright growers.

    I would suggest visiting some local garden centers; they would be stocking the best specimens for your region and often have test gardens where you can see mature plantings.

    You will have to contact the local agricultural extension services in your country for this one! Digging a trench near a neighbors trees will likely damage them, resulting in legal trouble, which we can't really help with.

    They will probably overwhelm you in the first growing season. Leyland cypress typically grow 50 feet (15 meters) tall by 12 feet (4 meters) wide. They will outgrow those pots quickly. While they do accept severe pruning, and trimming annually for height, you would be better off to trade these in on a smaller evergreen.

    Our experts suggest either pruning or treating the hedge with an organic or copper based fungicide. Here's a link to an article about unwanted moss on foliage:
