Finding suitable types of trees for coastal gardens is not so easy. A lot of ornamental trees struggle with the exposure to wind and salt. Here is a guide for the best decorative trees that will survive near the sea. Choose deciduous trees or suitable types of evergreen trees for shelterbelts.
Every gardener that I know wants to grow different types of trees in their gardens. If you have a garden in a coastal area you know that you are limited in the choice of garden trees and that it is much more difficult to grow nice decorative trees.
Trees that are grown in a coastal climate have to be able to deal with severe winds and salt spray. They also don't tend to grow to the size they would grow to if they were in a sheltered garden and often they have a windswept shape. The branches facing the main wind direction are getting 'pruned' by the wind leading to those shapes.
Choosing suitable trees for this climate is essential for success. Unsuitable plants will not grow, the foliage will burn from the wind and sometimes they will neither live or die. These unfortunate plants will look crippled and sick and will be everything but decorative.
Some types of evergreen trees can be used for creating shelterbelts that will protect from the prevailing winds. Some deciduous trees are also suitable for this purpose but they, of course, won't offer the same amount of protection in the winter than evergreen trees. Good choices for this are pine trees (Pinus contorta, Pinus radiata).
Gardening Tips For Success With All Types Of Trees
Get advice from your local garden center on the best choice of garden trees for your area.
Choose the spot for your tree well. Consider drainage, light, and exposure.
Take the time to prepare the ground. Add good compost and fertilizer and loosen the soil up well.
Planting a tree: dig a hole that is about twice the size of the rootball. Backfill with good soil and firm well. Don't forget to water in well.
Stake the tree: Use minimum one stake, two is better. A good quality tree tie is a small investment and well worth its money because it won't damage the tree.
Keep the tree watered in dry weather until well established.
No Grass Around Trees! Use bark mulch or grass clippings around the base of your trees. This will ensure that the trees won't get damaged with lawn mowers or strimmers. Once the bark is damaged it cripples the tree and the damage is irreversible! This is one of the main reasons for failure of trees in my opinion!
