Evergreen trees require extra care during the summer season. They are easily affected by the hot and humid climatic condition and thus they need to be watered every ten to fourteen days during the summer months. However water should reach up to the deep roots (6 inches minimum). To prevent loss of water from the tree, use peat moss or grass clippings.

Evergreens thrive well if they are trimmed late in the spring. This is needed so that the inner branches develop well. This will also make the tree or the shrub more solid. Regular trimming should be done in formal tress. There should be no tattered branches coming out of the tree. Shape the tress if they are deformed.

Winter sun and excess of wind can also affect the evergreen tress. They suffer from winter burn due to this. The tress dry up and the branches crack up due to the wind’s force or the weight of the snow.

Always remember to water them before the winter months. Deep watering is required before the snow sets in. to protect the evergreen tress from the chilly winter, use straw mats or screens of burlap. Shield the plant only from the sun facing side when the wind and winter both are not that much. Covers or Burlap boxes required proper ventilation. To prevent the branches from cracking, you can tie piece of cloth on tall and thin evergreen tress or shrubs. Use boards for propping the old tress which has huge limbs. This will prevent its breakage under the weight of the ice or snow.
