Your Botanical Tower® package arrives at your home containing two 94"upright posts, two cross-members, the decorative top section, four cast iron brackets, and all necessary hardware needed for a quick trouble free assembly. Once installed, your Botanical Tower® will stand at roughly 72" in height, and 22" in width, creating three 15" X 15" display areas. The 22"- 24" planting depth will insure a secure installation that will allow you to hang items of significant weight, such as large hanging planters, garden bells, and the like. While you're digging, you may want to take advantage of the opportunity to plant a flowering vine to grow up and along the surfaces of your Botanical Tower® Several options would include wisteria, clematis, hydrangea, sweet pea, jasmine, Chilean bellflower, and climbing rose, to name a few. As a rule, cedar should not be set in concrete. In most cases it should be set directly into the ground. In the case of all Botanical Towers®, the holes should be dug to a depth of 22"- 24", 6-7" wide, and roughly 18 ½" apart OC (on center) As with most rules, though, there are often exceptions. Here are a few. Many cedar manufacturers suggest digging the hole an extra 6" deep, and backfilling with gravel before placing the posts. The school of thought is that this measure will improve drainage around the base of the post, and further insure the integrity of the wood. In sandy soils, this extra step may prove unnecessary, but in regions with red clay soil, it might be well worth your consideration. In contrast to rule #1, there are those who suggest using a combination of 6" gravel and the use of concrete to set the posts. In sandy soils in particular, this method would add an extra measure of strength, while benefiting from the natural drainage properties of the soil. As cedar naturally resists decay, there are really no wrong installation methods, and it is best to use the one that best suits your soil conditions and personal preference.
