If you are going to let them grow to their entire height, then evergreen cypress trees do not typically require a lot of pruning. These trees typically grow bushy green limbs which remain within a certain shape, making care comparatively easy. But should you prefer to make a topiary or wish to keep the tree from growing past a certain point, pruning is required so as to keep the appearance.
Cut out dead limbs as soon as you find them, regardless of what time of year. Use loppers for then a pruning saw for larger ones. Cut back the branch to the main stem of this tree, but never flush with the trunk.
Cut out diseased or dying limbs once you find them turning brown. If they are still yellow, and you believe you could salvage them with proper watering and added nutrients, hold off pruning. Otherwise, remove the limb back to the trunk, as you would a dead limb.
Shape the cypress tree only if it needs it or you are working to train it to a certain design. Trim the tips of their branches, taking off no more than one third of the length at any particular time. Trim cypress to shape in the winter, once the tree is dormant. Use loppers to make your cuts in a small angle so that moisture will not build up on the strategies and to encourage new growth.
Snip the top off your cypress if you would like to keep it from growing taller. Know that once you do this, it may start to branch out more, spreading wider. In this case, shaping the tree may be required annually. Keep the very best by cutting it back annually to keep it in the size you want. Cut the top branch at a 45-degree angle to keep moisture from resting on the timber.
Cut out branches all over the tree if you observe that the greenery is turning brown at the center region. This is a sign that the branches are too dense to permit air and light to penetrate. Remove select branches, spaced out all over the tree, to make holes to bring about light and air circulation. Cut them back to the main trunk.
