The variety of indoor flowering plants sold in flower shops today is truly astounding. Many amateur gardeners, after purchasing a beautiful flowering plant, eventually discover that watering and proper care alone are not enough to ensure its well-being and abundant blooms.
In such cases, experienced florists recommend using immunostimulants to restore the vitality of your favorite green plant and ensure its normal development. Among the most popular immunomodulatory medications, Epin stands out, as it is effective for both garden and indoor plants.
General information about the drug Epin
Epin is a phytohormone successfully used in floriculture to stimulate growth, rooting of cuttings, seed germination, fruit ripening, and enhance flower resistance to disease and fungal infections. The product strengthens the plant's immune system and is also used as a preventative measure to activate cellular metabolic processes. Epin is manufactured using microbiological technologies.
Compound
The active ingredient in the product, epinbrassinolide, is an artificial phytohormone produced synthetically but similar to the hormone naturally produced by plants. This allows for rapid plant recovery at the cellular level after exposure to various negative factors:
- moisture deficiency or excess;
- temperature changes;
- lack of lighting;
- recovery from illness.

This activates the formation of protein compounds and stimulates fermentation, which leads to an increase in the immunity of the houseplant.
Epin is an alcohol- and soap-containing phytopreparation that allows particles of the active substance to remain on plant leaves.
Beneficial properties
Thanks to the growth stimulator the following occurs:
- accelerated growth of planting material (seeds, bulbs, tubers);
- improving root formation in cuttings;
- extension of the flowering period;
- acceleration of forcing of bulbous crops;
- increasing stress resistance during transplantation, temperature changes, low light, and moisture deficiency;
- increasing the body's defenses against the harmful effects of pathogenic microflora, fungal diseases, and harmful insects;
- activation of recovery processes due to the formation of young shoots.

Using Epin allows you to reduce watering. It interacts with various fertilizers, which has a positive effect on the development and flowering of indoor plants.
Using Epin for indoor plants
Epin is available as a solution in small ampoules. Although the packaging depicts vegetables, the product is successfully used in floriculture for growing indoor flowers.
Indications
The main indications for using an immunostimulant for indoor plants include weakened immunity due to negative environmental influences or improper plant care:
- lack of watering or nutrients;
- poor lighting;
- exit after a period of rest.
Efficiency
The effectiveness of the phytohormone has been proven through its use on many indoor flower crops:
- the plant's immunity increases;
- the duration of flowering and the appearance of new flower buds increases;
- metabolic processes at the cellular level are improved;
- The decorative qualities and appearance of the flower are enhanced.
In addition, by using a herbal preparation to force flowers on bulbous crops in winter, you can get a flowering plant several weeks earlier than expected.
Hazard class
Epin differs from other immunomodulators in that it is classified as hazard class IV, meaning it is completely harmless to the human body. It also does not harm bees, which are highly susceptible to various toxins and pesticides, and does not settle in wastewater.
However, the product's manufacturers recommend certain protective measures, including wearing gloves and a cotton-gauze bandage when treating plants. When working in rooms or offices, it's advisable to open the windows.
Concentration and methods of dilution of the solution
Before you start using the herbal preparation for indoor plants, it is recommended that you carefully read the attached instructions for use.
According to the instructions, the phytohormone is highly water-soluble. One ampoule is sufficient to prepare five liters of solution. Each ampoule contains 40 drops of stimulant, making it easy to calculate the required number of drops to prepare a solution for a specific application.

Only freshly prepared solutions should be used, observing all proportions specified in the instructions. Failure to follow these recommendations and exceeding the concentration of the solution can harm plants and slow their growth. A weak concentration will not achieve the desired effect.
Epin must be stored in a cool, dark place, away from direct sunlight. The prepared solution should be used within two days.
For spraying
For indoor flowers planted in pots, the biostimulant is best used by spraying in the following proportions: 4 drops of Epin per glass of boiled water.
After treatment, the plants must be left in the dark for several hours.
For forcing bulbs
To force flowering in bulbous plants, a growth stimulant is also used. The bulbs are soaked in a solution prepared at a ratio of 1 ampoule per 2 liters of water and left for 12 hours. The growth stimulant accelerates the flowering process of bulbous plants, resulting in results several weeks earlier than expected.
When cutting
One method of propagating houseplants is cuttings. However, not every houseplant cutting can root.

To do this, first place the cuttings of the selected plant in a freshly prepared solution of this phytohormone at a ratio of 1 ampoule per 2 liters of warm water. After roots form, transplant the cuttings into fresh soil.
Seed treatment
Seeds of most flower crops are treated with a solution of 4-6 drops per 100 ml of warm (25-28°C) boiled water for 24 hours. This results in rapid seed germination.
Safety precautions when working with Epin
The herbal preparation is not considered toxic; however, it contains alcohol and soap solution, which can cause allergic reactions or skin irritation if they come into contact with exposed areas of the body. Therefore, it's important to follow these guidelines:
- When handling, use a protective bandage and rubber gloves;
- Avoid smoking, eating and drinking near the drug;
- Do not use near open flames;
- After finishing work, it is necessary to wash exposed areas of the body under running water and rinse the mouth;
- Follow the storage rules for the drug: store it in a dry, cool place, out of the reach of children and animals, separate from food.
If Epin enters the gastrointestinal tract, gastric lavage with potassium permanganate solution and administration of an adsorbent are necessary. If there is no improvement, seek medical attention to relieve symptoms of intoxication.
Frequently asked questions about application
Epin is a synthetic biostimulant, identical to the natural one, an adaptogen that ensures the normal development of indoor plants by increasing their immunity and improving metabolic processes at the cellular level.
