Installing a pole in your garden soil platform needs some type of experience and professional planning. However it’s not impossible to do it if you got the strength, material like the post itself and a cement mix ready to pour inside the cavity where do you want to place it. This is critical because without a foundation you will not be able to hold the post against the resistance of the sail  shade tensile pressure. The sail shade size as well will determine the size and the mass of the foundation needed.
