When we talk of fences, we almost always think about privacy and security as well as the protection of our crops if you are a gardener. And as a gardener, we are concern about our crops that we want to grow each day with those cares we put in everyday for them to grow as fast as we want them to be. And if our place is so wide open to our kids or children who might go and play, we might get upset when our plants are accidentally damaged. A fence made of wood of three feet would serve the purpose to contain our children when they play and not intrude on our gardens.
But what if cows or other strong animals are the problems, a wood fence of that height won't do the trick and you have to put up a bit sturdier structure to prevent them from intruding to your area. This type of problem would require a little amount of studying and budgeting to keep your gardening an enjoyable work to live with every day. But before rushing things to put up your fence, go to your drawing board so you could save a lot of time and money and study carefully the kind of fence, the height of your fence, the materials to be used, the manpower you need to build it and the entry and exit points of your fence as this would spell a lot of importance to you when changing your access plans to your property later on.
After you have completed the draft of the fence including the height you would be constructing, you could start measuring now the perimeter of your property to be enclosed with that fence and you might be surprised that what you initially estimated on your drawings would be quite different on the actual situation of your property's topography and for that matter your budget would be in great variance with the probable cost of the fence if you would follow the actual conditions. Good if your cost is going down and that would be favorable to your budget, but what if the actual situation would call for a bigger cost to put the fence?
There are properties whose boundaries have steeped portions while others contain one or two creeks and therefore enclosing that portion to prevent animals to intrude would be very costly compared to your original plan of using wooden materials. These types of locations necessitate the use of other types of materials that could withstand water and penetrate rocks to imbed your posts for the fence. In many cases, a combination of steel and concrete materials is needed for such structure that would adapt to water and other environmental situations.
In the event your budget would not permit to construct a fence using steel and concrete materials, the best move you could is to change your plans drastically, say studying the possibility of phasing your fence schedule. Start one or two sides of your property and cut a portion where you are starting your gardening and concentrate on fencing that specific area since that is yet the vulnerable portion of your property from intruding animals.
