Abstract
ABSTRACT
A container for plants, especially suited for trees and bushes which are to be grown and developed in a nursery for a prolonged period and then shipped and transplanted without disturbing the root growth, has angled corners and bottom corner openings preventing root girdling. The container includes an open lattice wire basket of square or rectangular shape and a pulp or fiberboard liner composed of a flat bottom piece, and two side wall defining pieces snugly engaging the sides of the basket and having interlocking flaps. Holes are provided in the bottom corners of the side pieces. A perforated top piece of cover can also be provided to protect the potted plant during shipment. The corners of the liner block girdling and circular interwining of the roots causing them to grow downwardly to the holes thus developing a spreading root pattern for transplanting.
Transplanting is easily effected by tearing out the liner section and burying the basket. The liner material can also be bio-degradable. The wire strands of the basket are widely spaced so as not to interfere with spreading root growth after transplanting.

Description

SPECIFICATION
This invention relates to the art of potting relatively large plants, such as bushes and trees, permitting them to grow for a prolonged period in a nursery to develop roots which ~vill spread when transplanted and yet containing the stem and roots 5 for easy transportation without loss of the potting soil.
Specifically, the invention deals with an open lattice rigid wire basket with a flat bottom, tapered side walls, and square corners, and a pulp board or cardboard liner for the basket having holes at the bottoms of the corners together with a 10 perforated cover preventing dislodging of the potting soil during shipment.
Hereto~ore, pots, tubs, burlap sacks, and the like containers for the stem and roots of trees and bushes have had configurations which cause the roots to girdle and wind around the confined area of the container. It has been found that the thus developed circular root pattern will be maintained even a~er the bush or tree is removed from the container and transplanted.
Thus, instead of spreading outwardly, the roots will continue to circle in conformity with the paths that were established in 20 the container. This root girdling stunts growth and leaves the transplanted bush or pIant without a good root anchor. The heretofore used pots and tubs a]so had to be removed ~or transplanting, causing loss of soil and leaving the roots exposed.
Roots and stems balled up in burlap bags had to be buried in 25 ~ surrounding soil even when temporarily stored in nurseries, .
. .
~: . . . .. ,, ,, . .: - . . .. . ~ ., ii6~
and the burlap bags offered no protection against loosening of the soil around the roots.
According to this invention, the deficiencies of the prior art handling of potting large bushes and trees to encourage nursery growth and to facilitate shipment for transplant are avoided by pot~ing the plants in rigid square or rectangular wire baskets supporting fiberboard or cardboard liners which provide square corners and open holes at the bottoms of the corners.
A perforated fiberboard or cardboard cover can also be provided to prevent disruption of soil during shipment. The square corners provided by the liner form obstructions causing otherwise girdling roots to grow downwardly to the holes where they can either grow outwardly beyond the basket or, if ex~osed ~o the atmosphere, will wither and stop growing. This establishes a ?
" 15 growth pattern within the con~ainer which will develop outward root growth after transplanting. The liner adequately confines the soil prior to transplanting and can easily be removed or - ruptured at the transplanting site where the basket is buried in the ground. Further, the liner can be bio-degradable so that it will eventually disintegrate after the basket is buried in the ground.
., .
The containers of thls invention make possible ~he potting of trees for a prolonged growing period, up to three ~zears,`
;:
~ .
before transplanting. Thus, a nursery can grow large trees for easy shipment in containers in which they were originally planted~
.
. ~ .
~ ' 5~
The root growth is not disturbed and the nutrients and soil surrounding the roots in the container are protected during shipment and remain undisturbe~ after transplanting.
The baskets are conveniently siæed for the anticipated sizes of trees or bushes tO be grown therein and can, for example, vary from a 16-inch square at the bottom with a 14-inch height to a 4()-inch square at the bottom wîth a 26-inch height. The sides preferably have a taper of from 10 to lS
degrees. The wire for the basket is relatively heavy and rigid with a diameter of about 1/4 to about 3/16 inches. The basket is preferably formed with three hoops and eight loops with the loops being spot-welded to the hoops.
The basket liner can be composed o~ any suitable fiberboard or pulp board fortned, for example, from waste or recycled paper pulp and will preferably have a thickness of from abou~ .û60 to about .080 inches. If desired, the liner could he composed of thinner plastic sheets.
The present invention provides a potting container for plants having an open lattice wire hasket with a bottom, sides and an open top with angled corners of not more than about 90 degrees between the sides and having a liner fittiTIg the bottom and sides of the basket with holes in the liner at the bottom corners thereof.
In a further aspect of the present invention the potting container is a square tapered tub for planting trees and the llke .
composcd of a wire basket having a Elat bottom, four side walls tapering upwardly from the periphery of the bottom having right angled corners therebetween and an open top larger than the bottom. The basket is composed of widely spaced hoops and 5 loops of wire strands with open spaces therebetween. A sheet matexial liner in the basket covers the open spaces and lies against the bottom and side walls of the basket with conforming right angled corners. Holes in the liner are provided at the bottoms of the corners.
The invention also provîdes a method of potting and transplanting large plants where ~he roots and bottom of the stem of the plant is embedded in earth and is surrounded by an earth retaining liner ~hat has angled corners and holes at the bottoms of the corners. This liner is supported in an open basket. The 15 plant is allowed to grow in the basket supported liner for developing a root pattern and root girdling is blocked at the corners of the liner forcing the roots to grow downwardly to the holes. The thus potted plant can be transported for transplanting after its root pattern has developed and the liner is then 20 removed wlth the basket being buried in the ground so that the roots may spread through the open lattice of the baske~ to anchor the plant and supply nourishment to the plant.
Further features of the invention include constructing the liner of three pieces of fiberboard includin~ a bottom piece, 25 and two slde pieces with interlocking flaps. A perforated cover - ~ ' . - ~
.
for the lined basket can be provided to fit in the open top of the basket supported liner and this cover has a central aperture for the stem of the plant with a myriad of apertures surrounding the central aperture to accommodate water drainage.
In another specific aspect of the Lnvention, the basket has three square hoops increasing in size from the bottom to the top of the basket and a plurality of wire loops are secured to these hoops to provide supporting legs extending along the sides and across the bottom of the basket. The side walls of the basket preferably taper at angles of fmm about 10 to 15 degrees.

Figure 6 is a fragmentary perspective view of the container of this invention showing the spreading root pattern that is developed in the container.
In Figure 1, a prior art tub or pot P of cylindrical 5 configuration is illustrated as having ~he stem S of a large plant such as a bush or tree planted in soil or earth E filling the pot.
Roots 1~ radiate from the stem and, as shown, are directed by the cylindrical wall of the pot P in a circular direction to girdle the-stèm S. The roots will eventually intertwine themselves 10 - within a circular peiripheral pattern. It has been found that roots have a mernory fron~ initial growth and will continue to follow their initial growth pattern even when the confining tub or pot P is removedO
Thus, even after transplanting, the stem S of the tree ~-will have little or no lateral anchorage from the roots R and the roots, in continuing to circle about the stem, will soon absorb all of the nutrients from the small area of earth E in which they are encased. Thus, the tree will be stunted in growth and have -little or no root anchorage against uprooting by wind and erosion of the soll.
The contalner 10 of this invention, on the other hand, will develop a ~root pattern that will spread after transplanting even though a portion of the container is buried in the ground upon transplanting. -As shown in Figure 2, the container 10 of this invention is composed of a basket 11, a liner 12, and a cover 13.
.
-, ~L~6~LS~i~
The basket 11 is of open lattice wire construction with a square flat bottom 14 and four tapered side walls 1~
diverging upwardly from said bottoln to an open top. The side walls diverge from the bo~tom at an angle of about 10 tO 1;~
5 preferably 12 degrees.
The basket 11 is composed of three square wire hoops including a bottom hoop 16~ a middle hoop 17 and a top hoop 18.
Eight loops of wire, 19 to 26 inclusive, formed from four ~ire strands, embrace the hoops with two loops being welded to each 10 side of each square hoop in spaced relation from the corners of the hoops and from each other.
As shown, the loops 19 and 24, 20 and 23, 21 and 26, and 22 and 25 are formed`from single lengths of wire. Thus, the loops 19 and 24 have rounded bight top ends 27 above the 15 top hoop 18 with side legs 28 depending therefrom over the three hoops to bottom legs 29 which are bent under the bottorn hoop 16. The cnds of this wire strand is welded together at 30 and welds 31 secure the side legs to the hoops. The loops 20 and 23 are similarly formed with top bight portions 27, side 20 legs 28, and bottom legs 29.
~ The loops 21 and 26 are ~ormed from a single ~ ire strand with top bight portions 32, depending side legs 33 and bottom legs 34 bent around the bottom hoop 16 and underl~-ing~ the - legs 29. The ends of this wire strand are similarly welded together at 35 and welds 3O connect the side legs 33 with ~he , ~ 8 '. .

6~5~4~
hoops 16, 17 and 18 while welds 37 connect the legs 29 with the legs 34. The loops 22 and ~5 are similarly formed from a single strand of wire with similar top bight ends 32, side legs 33 and bottom legs 34.
Thus, the basket is formed from three hoops of wire and four strands of wire forming eight hoop embracing loops with rounded top bights or ends e~tending above the top hoop.
The liner 12 is composed of a flat square piece 38 of pulp board or cardboard or plastic sized to fit the bottom of the basket 11 to rest on the legs 29 and 34 thereof. Two side pieces 39 of similar pulp board, cardboard, or plastic, cooperate to form the sides of the liner resting on the bottom-38. Each piece 39 has an end wall 40 with side flaps 41, 41 folded at 42 to form right angle COrnerS. The side flaps 41, 41 have slots 43, 43 extending horizontally inward from their free ends thue providing between the slots a tab 43a in the middle section of each flap 41 at the free edge of the flap. These tabs 43a are - adapted to be overlapped with the end edges of the flaps 41 being inserted in the slots to form an overlapped interlocking tongue " 20 and groove connection joining the flaps to form side walls for the end walls 40 thereby providing a closed periphery upstanding ` ~ square tube. The pieces forrning the sides of the liner are cut and folded to conform with the taper of the basket so that they will fit snugly against the wire strands of the basket.
The bottom corners of the liner l3 are cut out to form semi-circular open bottom holes 44 bisected by the fold ~ .. , ' .: .
~6~
lines 42 ~t the corners of the liner. ~hese holes can have a diameter of 1-1/2 to 2-1/2 inches clepending upon the size of the liner.
As shown in Figure 6, the stem S of a tree or the like plant has roots R embedded in earth E filling the liner 12 contained in the basket 11. These roo~s are branched from the stem S and when they reach a wall of the liner 12 they will follow the wall until they reach a corner at a fold line 42 of the liner whereupon instead of circling the perimeter of the liner they will grow downwardly at R1 to eventually enter the holes 44 at the bottoms of the corners where some of them might project through the holes and if exposed to the atmosphere they will dxy up. However, the corners create desired downwardly growing roots R1 to form a root pattern outwardly of the stem S whichj i - 15 when released from the confines of the liner 12, will continue to grow downwardly and outwardly in the earth surrounding the submerged basket 11 to form a good root anchor and a spreading root development for nourishing the stem S.
If desired, the top sur-face of the earth E potted in :
tbe liner 12 can be covered with a sheet 13 of pulp board, or the like material. Thls sheet has a central hole 45 for loosely embracing the stem S and has a myriad perforation 46 surround-ing the central hole 45 to vent the earth E to the atmosphere and to accommodate drainage of water into the earth. A slot 47 25~ extends radially frorn the hole 4,5 to one edge of the sheet 13 so that th~sheet can easily be placed around the stem S.
-: - 1 0 - .
' s~
Tlle sheet is especially useful when transporting the potted tree or bush for transplanting since it will prevent disruption of the earth E. The sheet also prevents weed growth around the stem.
When the potted tree or bush is transported to the 5 transplant site, a hole sufficiently large to submerge the entire basket 11 is provided, and the liner 12 is torn out through the open lattice of the basket as rnuch as is practical so that the submerged roots can readily grow through the wide s)pen spaces of the basket, both outwardly and downwardly. The basket is 10 preferably submerged above the bigh~ ends 27 and 32 of its loops.
- From the above descriptions it will thus be understood that this invention provides an ine~pensive, lightweight container for potting large plants such as bushes and trees which will develop a spreading root growth pattern, can be used in nurseries 15 for a prolonged period to grow trees up to threc inches in diameter, is easily transported ~o a transplanting site without - disruption of the roots and the soil surrounding the roots and is then buried into the ground where it will not interfere with the spreading root growth.

3. The container of claim 1 including a perforated cover for the basket sized to fit in the open top of the liner and having a central aperture for the stem of a plant with a myriad of apertures surrounding the central aperture to accomodate water drainage.
4. A potting container for growing, transporting, and planting plants with roots embedded in soil filling the container and remaining in the container throughout the growing, transporting and planting thereof which comprises an open lattice wire basket having a bottom, sides and an open top with angle corners of not more than about 90° between the sides, a removable liner in the basket fitting the bottom and sides of the basket and having angle corners mating with said angle corners of the basket, said liner having unimpeded holes at the bottoms of the angle corners thereof openly registering with open spaces of the open lattice wire basket, said angle corners cooperating with said holes to block girdling of the roots of the plant and guide the roots to said holes for developing a spreading root pattern, and said liner being removable from said basket without removal of the soil and plant supported therein from the confines of said basket so that the roots of the plant may spread through the open lattice of the basket when the basket is buried in the ground to anchor the plant and supply nourishment to the plant.
5. A square shaped tapered tub which is tapered from a large top to a smaller bottom and is to be filled with earth for potting trees and large plants to grow therein a non-girdling root pattern which comprises a wire basket having a flat bottom, four sidewalls tapering upwardly from the periphery of said bottom and having right angle corners therebetween together with an open top larger than said bottom said basket composed of widely spaced hoops and loops of wire strands with open spaces therebetween, a removable temporary earth retaining sheet material liner in the basket covering said open spaces and lying against said bottom and sidewalls of the basket with conforming right angle corners, said liner having an unimpeded hole at the bottom of each right angle corner adapted to receive roots therethrough and said right angle corners cooperating with said corner holes to block girdling of the roots of the plant and guide the roots to said holes for developing a spreading root pattern.
