Sustainable Design: Planters
Large Planters for Trees manufactured by DeepStream use a separate plastic liner, with state-of-the-art drainage especially important with a heavy planting like trees, inside an outer box façade supported by an aluminum frame or foam blocks. The plastic liner ensures maximum durability, as the wet planting medium and roots never touch the outer shell.
It is important to consider the stability of your installation and pick a form factor appropriate to the ultimate hight and size of the tree and maximum wind conditions. Trees, such as palms, without a lot of branches and foliage have lower wind resistance. Palms do better on windy roof tops and terraces here in hurricane-prone Florida. While the weight of the planted planter will keep it from blowing away, a planter with a narrow base, relative to the leverage of wind against foliage, can tip over.
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.
Large Planters for Trees can be built in place, using Custom-Welded Plastic Planter Liners manufactured by DeepStream for your projects in 1/4" or 3/8" co-polypropylene, as used in the construction of large chemical tanks. Polypropylene is extremely durable and is impervious to the sun's UV rays, protecting your liners even if they are not completely buried. Polypropylene is available in black and natural (off-white).
Construction techniques include double-welded gussets, shown in the bottom pictures, or cross-straps, as shown below, 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 selecting appropriate planting mediums are critical when plantings are expected to be maintained for years without digging them up.
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.
When purchasing a Large Planter for Trees, it is critical to note that as trees grow, their root ball gets larger and larger. With some species, the container size will limit the size of the tree; with others the root ball continues to grow. An ever-expanding root ball will either push the tree up on a pedestal of its own roots, or push out and eventually break the liner.
If you visit the ancient jungle ruins of the Mayans and Aztecs, you will recognize that even the giant stone blocks of the temples, weighing thousands of pounds, will be pushed apart, split and toppled by tree roots. Streetscapes constantly have to deal with root control. This, along with selecting an appropriate planting mixture and micro-climates, is another important reason to consult with a Landscape Architect experienced with container gardening when planning your project.
DeepStream's stock planter liners, and Tournesol Siteworks ABS planter liners, are molded in one piece so that tree roots have no week spots to attack. DeepStream's custom-welded liners used for major plantings are not only engineered with thicker 3/8" co-polypropylene, or thicker HDPE, as used in construction of large chemical tanks. The panels are gusseted and welded from both sides before being water-tested to ensue their ultimate durability in your project.
The bases of trees will be push 6-12" by their roots over a five to ten year period as the trees grow to their mature hight for that size planter. Knowing that in advance, planted the root ball deeper in the planter and filled the recess with other plantings for the duration.
