Polypropylene is extremely durable however it is not impervious to the suns UV rays and should be completely buried.
Construction techniques include double-welded gussets, shown in the bottom pictures, or cross-straps as shown above, for optimum wall support. You can add side wall drainage holes on site with a simple hole saw. Drain Packs, proper drainage techniques to slow the water flow, and the selection of appropriate planting mediums are critical when plantings are expected to be maintained for years without digging them up. Dedicated spaces for plantings limit problems to identifiable areas.
As with all custom and semi-custom garden products produced by the hands of craftsmen, delivery times will grow longer as Spring progresses into Summer, even with "quick ship" programs, so plan ahead and order early.
If your planters will not be dug up and replanted every year then we strongly recommend adding Drain Filter Packs for each drain.
A three-part filter combines the waffled plastic backing of TREMdrain, three layers of filter fabric, and Biobarrier buttons to inhibit root growth.
They may not stop aggressive root systems like Bamboo and Clusia.
Filter packs, when used in conjunction with clean 1-2 mm inorganic drainage material to slow the flow of the water to the drain, could prevent clogged drains for a decade or more.
While enjoying your outdoor wood planters keep in mind that drainage is critical to the health of your plants grown in containers, and it is very difficult to remedy after the fact. Generally more "tended" plants die from drowning than from lack of water. "Old School" drain holes on the bottom and "gravel" drainage medium simply do not work and will quickly clog.
DeepStream pioneered modern drainage practices with side-wall drains and 3-layer drain packs. DeepStream places from one to three 3/4" threaded drainage ports on its 12 stock proprietary plastic planter liners, to which various plugs, hose barbs and valves may be attached. Liners are non-structural and are meant to be placed inside planter boxes.
Depending on your plants, planting mixture, and local weather, you may need to add more drains. Additional drain holes can be added as required by drilling additional holes in the side walls. DeepStream installed drains are centered about 2" above the bottom to allow the clay "fines" in planting mediums that are responsible for clogging to settle to the bottom.
Standard ABS liners and custom-welded liners come without drain holes, but they may be drilled as required. Reservoir liners come with one drain port, and more cannot be added.
