Plant irrigation device

1. An irrigation device for facilitating growth of plant, comprising:

a mat comprised of a first sheet of a heat fusible material that is air and water permeable and a second sheet of a heat fusible material that is air and water permeable, the first and second sheets of material being attached to one another, and the mat having an opening through which a plant extends; and

a drip tube disposed within the mat between the first and second sheets of material, the drip tube having an open end connectable to a water source and a series of apertures along a length thereof within the mat permitting water to exit the drip tube and through the lower surface of the mat;

wherein the drip tube within the mat is a closed loop having a spaced apart generally concentric or spiral configuration; and

wherein the first and second sheets of material are heat fuse-attached to one another adjacent to a peripheral edge and adjacent to the drip tube so as to hold the drip tube in place with respect to the first and second sheets of material.

2. The irrigation device of claim 1 , wherein at least one of the first and second sheets of material inhibits roots or plants from growing therethrough.

3. The irrigation device of claim 1 , including stakes extending through or associated with the mat for directing water into the ground towards roots of an associated plant.

4. The irrigation device of claim 3 , wherein the stakes are hollow and have an inlet, for receiving water from the drip tube, and a water outlet.

5. The irrigation device of claim 3 , wherein the stakes comprise channels directing the water downwardly along a length thereof.

6. The irrigation device of claim 3 , wherein the stakes have upwardly directed barbs for retaining the stake within the ground.

7. The irrigation device of claim 1 , including a slit formed in the mat to facilitate placement of the mat around an existing plant.

8. The irrigation device of claim 1 , including artificial turf having a substantially same configuration as the mat and disposable over the mat.

9. The irrigation device of claim 1 , including a substantially rigid support to which the drip tube is connected.

10. The irrigation device of claim 9 , wherein the support defines an open-faced channel configured to receive the drip tube therein and having a plurality of water outlet apertures formed along a length thereof.

11. The irrigation device of claim 1 , including water emitter nozzles operably connected to the drip tube for spraying or dripping water therefrom.

12. The irrigation device of claim 1 , wherein the water source comprises an upper tube of landscape edging to which the open end of the drip tube is operably connected.

13. The irrigation device of claim 1 , wherein the mat includes polymers to increase water retention of the mat.

14. An irrigation device for facilitating growth of plant, comprising:

a mat comprising a first sheet of a heat fusible material that is air and water permeable and defining an upper surface of the mat, a second sheet of a heat fusible material attached to the first sheet of material and defining a lower surface of the mat, the second sheet of material being air and water permeable, wherein at least one of the first or second sheets of material inhibits roots or plants from growing therethrough;

an opening through the mat through which a plant extends;

a slit formed between the opening and an outer peripheral edge for facilitating placement of the mat around the plant; and

a drip tube disposed within the mat between the first and second sheets of material, the drip tube having an open end connectable to a water source and a series of water emitters having outlets spaced along a length thereof within the mat permitting water to exit the drip tube and into the lower sheet of material to irrigate below the mat;

wherein the drip tube within the mat is a closed loop having a spaced apart generally concentric or spiral configuration; and

wherein the first and second sheets of material are heat fuse-attached to one another adjacent to the peripheral edge and adjacent to the drip tube so as to hold the drip tube in place with respect to the first and second sheets of material.

15. The irrigation device of claim 14 , including stakes extending through or associated with the mat for directing water into the ground towards roots of an associated plant.

16. The irrigation device of claim 15 , wherein the stakes are hollow and have an inlet for receiving water from the drip tube and a water outlet.

17. The irrigation device of claim 15 , wherein the stakes comprise channels directing the water downwardly along a length thereof.

18. The irrigation device of claim 15 , wherein the stakes have upwardly directed barbs for retaining the stake within the ground.

19. The irrigation device of claim 14 , including artificial turf having a substantially same configuration as the mat and disposable over the mat.

20. The irrigation device of claim 14 , including a substantially rigid support defining an open-faced channel disposed within the mat and configured to receive the drip tube therein, the support having a plurality of water outlet apertures formed along a length thereof.

21. The irrigation device of claim 14 , including water spray emitter nozzles operably connected to the drip tube for spraying water therefrom.

22. The irrigation device of claim 14 , wherein the water source comprises an upper tube of landscape edging to which the open end of the drip tube is operably connected.

23. The irrigation device of claim 14 , wherein the mat includes polymers to increase water retention of the mat.
