A six-device-in-one material-saving consumer-and-manufacturer-cost-saving shipping-volume-saving multi-barrier-locking multi-root-gripping-and-water-flowing solar-light-securing sprinkler-securing umbrella-pole-securing trellis-securing anti-dig garden-and-tree-protecting vertical-truck-bed-extender-truck-bed-tonneau-cover stackable landscape barrier, comprises: a material-saving barrier, a barrier-connecting end-wing molded to the material-saving barrier for saving materials during manufacturing, being half of the length of comparable prior art and saving money for consumers by requiring less overlap at the ends of the landscape barriers and preventing animals from digging beneath the landscape barrier, when inserted into the soil vertically and bending to create a variety of corner angles, adjustable-corner-angling holes cut out from the material-saving barrier for lockingly supporting a garden-plant cage and promoting bending of the end-wing to form a variety of corner angles, material-saving tongue-locking openings cut out from the barrier-connecting end-wing, material-saving multi-barrier-locking tongues molded to the end-wing for saving materials during manufacturing, being half of the length of comparable prior art and saving money for consumers by requiring less overlap at the two barrier ends of the landscape barriers and securely supporting solar-stake-mounted lights or a trellis for vines or climbing plants or an umbrella pole or a sprinkler head or drip line and securely connecting multiple landscape barriers together by inserting through the material-saving tongue-locking opening and wrapping over the top or under the bottom of the material-saving barrier and securely locking multiple landscape barriers together by inserting through the material-saving tongue-locking openings, wrapping in the opposite direction through the adjustable-corner-angling holes, and again through the material-saving tongue-locking opening and anchoring the landscape barrier into soil and protecting garden plants from animals and saving materials during manufacturing, being half of the length of comparable prior art and saving money for consumers by requiring less overlap at the ends of the landscape barriers, a fold-over ridge folded from the top of the material-saving barrier for connecting the fold-over ridge of one landscape barrier the fold-over ridge of an another landscape barrier to create a shield to protect garden plants from animals and to create a shield to protect saplings from animals and to create a shield to protect trees from animals and to create a barrier to protect garden vegetation from animals and to create a tonneau cover of a truck bed and providing a guide for the barrier-connecting end-wing to slide into, at least one multi-barrier-locking stake punched out of the material-saving barrier for frictionally anchoring the multi-barrier-locking stake into soil by providing a serpentine stake shape and securing the landscape barrier into soil on an inclined or level surface and piercing into soil angledly or vertically, multi-root-gripping tunnels punched out of the material-saving barrier for saving materials during manufacturing by stamping out the multi-barrier-locking stake from the material-saving barrier and saving time and energy costs when the multi-barrier-locking stake is stored within the multi-root-gripping tunnel during packaging and storage and shipping the landscape barrier to reduce the space needed in each shipping container and to reduce the space needed for the landscape barrier and to reduce unit cost of the landscape barrier and securing the landscape barrier into soil by providing tunnel openings through which grass and plant roots may grow and soil may fill and locking into soil by providing tunnel lower edges below the multi-root-gripping tunnels, stake-storage-locking nipples formed into the material-saving barrier for locking the multi-barrier-locking stake to the material-saving barrier to provide a secure place to store the multi-barrier-locking stake when not in use and to prevent loss of the multi-barrier-locking stake, a stake-locking stopper formed into the multi-barrier-locking stake, a stake-storage-locking hole punched out of the multi-barrier-locking stake for locking the stake tip to the material-saving barrier for storage and shipping and securing the multi-barrier-locking stake in the soil by providing an opening through which grass and plant roots may grow and creating friction against the soil to secure the multi-barrier-locking stake, at least one single-angled sheath and double-angled sheath and triple-angled sheath, molded to the material-saving barrier for connecting multiple landscape barriers by providing an opening for a strap to be threaded therethrough to create a shield to protect gardens or saplings or trees from animals and a barrier to protect garden plants from animals and a tonneau cover of a truck bed and securing the landscape barrier to the utility holes of a pickup truck by providing an opening for the multi-barrier-locking stake to be threaded therethrough to create a vertical truck-bed extender and securing multiple landscape barriers to each other vertically by providing an opening for a multi-barrier-locking stake to be threaded therethrough to create a tree ring or planter ring of varying heights and guiding a multi-barrier-locking stake while being inserted vertically or angledly, tapered-locking ridges respectively pressed into the multi-barrier-locking stake for wedging into the single- and double- and triple-angled sheath to securely lock the stake for storage and shipping and wedging into the double-angled sheath to securely lock the multi-barrier-locking stake and wedging into the triple-angled sheath to securely lock the multi-barrier-locking stake and frictionally securing the multi-barrier-locking stake into soil, having friction provided by serpentine ridge-shapes, to prevent lifting when ground expands and contracts due to changes in temperature and securingly locking the multi-barrier-locking stake to the material-saving barrier by snap-locking to the triple-angled sheath.
