Description

TITLE. Method for coloring flowers and leaves of plants, in particular of ornamental plants in pots.

FIELD OF THE INVENTION

5

The invention relates to a method for coloring flowers and / or leaves of a plant with the aid of a coloring liquid.

For houseplants and in particular flowering houseplants or ornamental plants in pots it is interesting for some customers, prior to the sale and transport to the retail trade, to color the leaves and / or the flowers in, for example, blue or to color them.

BACKGROUND OF THE INVENTION

It is known to spray or spray liquids on plants, in particular the leaves, not only to treat a plant disease or an insect pest such as aphid, but sometimes also simply with a paint for decorative purposes. However, due to evaporation of the liquid on the surface of the leaf and also due to the low absorption capacity and permeability of the leaves, this method of painting or coloring is often ineffective.

It is also known that attempts have been made to apply the color liquids directly into the soil around the plant, so that the color liquid can be absorbed by the roots of the plant. This does not give a clearly good paint discoloration to flower and leaf, and also, however, a large part of the introduced liquid will sink downwards into the ground along the roots, as a result of which this method usually results in a great deal of paint loss, is too expensive, and therefore also not effective.

It is not only known to introduce nutrients or plant protection products into trees by drilling holes in the trunk and introducing liquid through a hollow pin; it is also known that dyes are injected into the stems of orchids etc provided they have thick stems. This method is unsuitable for plants with many leaves and / or with many flower stems, such as Anthurium house plants.

To color or add color to this type of plant, attempts have been made in vain to date to rapidly color flowers and plants by applying the above methods. The application of colorant or paint to the leaves of the plants is used to a limited extent, but generally does not give a natural and aesthetically pleasing result.

Summary of the invention 5

The invention has for its object to provide a method for coloring flowers and / or leaves of a plant with a color liquid with an improved and increased efficiency and for flowering plants and leaf plants with many leaves and / or many flower stalks as a result of which the above methods are not applicable. efficiency, whereby a natural and aesthetically beautiful result is also obtained.

To this end, the invention provides a method according to the preamble which comprises the steps of: - damaging the roots of the plant, such that an open liquid connection is formed with the juice stream in the xylem of the roots of the plant, and - in contact applying the coloring fluid with the damaged roots of the plant; all this in such a way that the color liquid is properly absorbed without many losses.

20

It has been found that by damaging the roots of the plant, liquids and in particular color liquids can easily be absorbed in the sap streams in the plant's xylem, whereby the dyes can be naturally transported to the leaves and the flowers and distributed there. This transport is greatly promoted by increasing the assimilation and evaporation of the plant by bringing the plant into a warm room with a temperature above the evaporation temperature of the plant so that the juice and liquid flow from the roots causes the moisture loss due to evaporation and respiration will replenish and the coloring fluid is transported quickly to the leaves and also the flowers.

30

In a preferred embodiment, the plant is placed in a heat chamber for a few hours to twelve hours to evaporate liquid via the leaves and to absorb color liquid via the damage to the roots of the plant. By placing the plant with the damaged roots, in contact with the colorant, in a warm room for 2 to 12 hours, sufficient evaporation and respiration will have occurred to achieve a uniform coloring of all leaves and / or flowers.

3

For damaging the roots, a choice is preferably made between: - crushing, and / or - breaking, and / or - cutting up, and / or - sawing.

It has been found that due to the choice of the above damage methods, the coloring liquid is absorbed particularly well, quickly and effectively by roots of the plant and transported to the leaves and / or the flowers.

Preferably, bringing the coloring liquid into contact with the root is selected from: - placing the roots in a foot bath with coloring liquid, and / or - pouring the coloring liquid onto the roots, and / or - immersing the roots in the color liquid, and / or applying an ampoule of color liquid to the roots.

The above-mentioned methods for supplying the color liquid provide an excellent and fast-acting method for coloring leaves and flowers of a plant.

Preference is given to the method in which the plants are selected from:

Anthurium, Spathiphyllum, Rosa L. Kalanchoe, Curcuma, Bromeliad. It has been found that this method is particularly effective and produces natural, aesthetically beautiful results with the aforementioned plants with many leaves and / or with many flower stems.

An advantage is provided by the embodiment of a plant provided with colored flowers and / or leaves according to the method of the invention.

Description of method of coloring leaves and / or flowers.

30

The method is of great advantage in coloring house plants and other small plants, which do not form a woody stem or comprise only stems and have many leaves and / or many flower stems. Before starting to color, the roots of the plant are "injured" or "bruised" by crushing, breaking, cutting or sawing the roots.

4

After the plant roots have been "injured", it is possible, for example, by means of a foot bath, or by pouring, dipping or applying an ampoule with color liquid or paint, to cause the color particles in the root to be absorbed in the sap flow from the plant to the leaves. and the flowers.

5

For the color liquid, various types of colorants are used in the colors yellow, cerise, black, blue and purple, etc. The purple colors that can make the colors blue and purple in the leaves and flowers are especially special.

Depending on the chosen method, the time required for coloring the leaves and / or flowers is long or short. It is usually sufficient to perform the entire treatment of a plant in a few minutes.

Step 1: the plant root ball is placed on a saw or the roots are bruised by hand, 15 Step 2: the plant root ball is deeply submerged, or an ampoule is applied to the roots, after which the 'liquid' in the roots causes the coloring liquid is taken up in the juice stream in the Xylem and the coloring liquid is transported to the leaves and / or the flowers to achieve a uniform, natural, discoloration there.
