Abstract

This invention relates to a coating for seeds comprising a polymeric material, a method of making and using the coating for improving the adherence of seeds to sloped surfaces, and seeds containing said coating. The invention also relates to a horticulture system for distributing the coated seeds to landscaping and/or agricultural surfaces.

First claim

We claim:

1 . A method for improving adherence of horticulture material on a sloped surface, said method comprising the following steps:
(a) providing seeds, (b) applying at least one polymeric material in liquid form to the seeds to form coated seeds, (c) drying the coated seeds to form dried coated seeds, (d) distributing the dried coated seeds to a sloped landscape ground surface, and (e) subjecting the dried coated seeds to moisture.

2 . The method of claim 1 , wherein the at least one polymeric material forms an insoluble coating on the seeds.

3 . The method of claim 1 , wherein horticulture material includes seeds and one or more of mulch and fertilizer material.

4 . The method of claim 3 , wherein mulch is selected from the group consisting of wood mulch, coconut wood fibers, and mixtures thereof.

5 . The method of claim 3 , wherein the fertilizer material is fertilizer pellets.

6 . The method of claim 1 , wherein the step of applying at least one polymeric material in liquid form is accomplished via spray application.

7 . The method of claim 1 , wherein the step of distributing the dried coated seeds is accomplished by adding the dried coated seeds to a container having a plethora of apertures, each aperture having a size sufficient to allow distribution of the dried coated seeds from the container.

8 . The method of claim 7 , wherein the container further includes at least one additional horticulture material selected from mulch and fertilizer.

9 . The method of claim 8 , wherein the container contains a ratio of dried coated seeds to horticulture material in the range from 1 to 4 to 4 to 1.

10 . The method of claim 1 , wherein subjecting the dried coated seeds to moisture includes moisture in an amount sufficient to cause the dried coated seeds to become tacky seeds.

11 . The method of claim 10 , wherein at least 50% of the tacky seeds resist movement from the sloped surface when subjected to water pressure of 30 psig over a period of less than 16 seconds.

12 . The method of claim 1 , wherein the at least one polymeric material is selected from the group consisting of polyvinyl acetate, polyvinyl alcohol, sodium polyacrylate, starch, pectin, carboxymethylcellulose, and combinations thereof.

13 . The method of claim 1 , wherein the seeds are turf seeds.

14 . The method of claim 1 , wherein the step of drying results in dried coated seeds containing less than 20% moisture.
