Deep vein thrombosis, or deep venous thrombosis, (DVT) is the formation of a blood clot (thrombus) within a deep vein, most commonly the legs. Nonspecific signs may include pain, swelling, redness, warmness, and engorged superficial veins.
Align with the centers of terminal posts. Now, dig the post holes (normally 6 wide and 18 to 24 deep) and set the line posts. Before concrete begins to set, adjust post height by carefully moving post up or down in footing. Top of line posts should be even with string; outside face approximately 1/4 inside.
For a 6-foot fence, for example, you need a 9-foot post, so that 3 feet can be underground. This means that unless you are building a 2-foot fence, which is unlikely in any garden, a 1-foot hole will not be deep enough to support your post. For main and gateposts, you should dig the holes an additional 6 inches deep.
