Gloxinia: the secrets of growing from seeds

gloxinia the secrets of growing from seeds Blog

Gloxinia is native to South and Central America. In nature, the flower grows on the slopes of the mountains. The leaves of the plant are large, velvety, dark green. The flowers are large, smooth or velvety depending on the species, bell-shaped. The color of flowers of various shades with a contrasting center with specks, or with a bright edging along the edge.

Growing from seed at home

Seeds are best sown between January and March. For germinating seeds, plastic containers, shallow wooden boxes or peat tablets are used. Be sure to have holes at the bottom of the container to remove excess moisture from the soil.

The soil for sowing seeds should consist of soils mixed in equal proportions:

  • turf;
  • sheet;
  • peat.

It is necessary to add a small amount of sand to this mixture. The finished soil must be calcined in the oven to destroy harmful bacteria and insect larvae.

Seeds are evenly distributed on the surface of the prepared soil and moistened from a spray bottle with warm settled water. The containers are covered with polyethylene to preserve humidity and placed in a room with good lighting and a temperature of 21-26 degrees.

The first shoots will appear in 10-15 days. Until the emergence of seedlings, the soil does not require additional moisture. After the first shoots germinate, the polyethylene is removed daily for a short time to ventilate the seedlings and moisten the soil as needed. At the time of active growth, seedlings must be provided with good lighting. Daylight hours should be at least 12 hours. With a lack of light, the seedlings will stretch.

As the seedlings grow, four picks must be made :

  1. When two true leaves appear on Gloxinia, the polyethylene is removed and the seedlings are seated in separate plastic cups. The transplant is carried out as carefully as possible with a lump of earth, so as not to damage the fragile root system of the sprout. The first pick is made a month after sowing the seeds. Then the containers with seedlings are again placed in greenhouses.
  2. The second pick is carried out as the seedlings grow. They are planted in pots with a capacity of 50 ml. After the second transplant, the seedlings begin to harden, accustoming them gradually to the air in the room.
  3. For the third transplant, use 100 ml pots.
  4. The fourth transplant is carried out at the age of 10 weeks. Seedlings are transplanted into containers with a diameter of 10 cm.

A layer of expanded clay is poured at the bottom of the pot, soil for flowering plants is poured over it. The soil can also be prepared independently by mixing garden and peat soil in equal proportions and adding sand and sphagnum to it.

Seedling care

In the phase of active growth, watering is done more often, trying to avoid drying out the soil. Watering is best done through a pan so that water does not fall on the leaves of the flower, otherwise it can cause powdery mildew. There should also be no stagnant moisture in the soil, as root rot can occur. Water for irrigation is pre-filtered. It should be two degrees warmer than room temperature. This will help the tubers absorb moisture well and prevent the risk of rotting. 30 minutes after watering, excess moisture is drained from the pan. During the flowering period, it is necessary to moisten gloxinia more often.

With proper care and timely fertilization, a large number of buds will form on gloxinia. On one bush, their number can reach up to twenty.

During the period of active growth, the plant is fed every 10 days. Feed gloxinia with fertilizer for indoor plants. In mid-August, the plant begins a dormant period. At this point, top dressing is introduced with a high content of potassium and phosphorus. Nitrogen-containing fertilizers are excluded during this period.


After the end of the period of active growth, the plant needs to be fertilized with frost. Oversaturation with fertilizers can adversely affect the condition of the plant, so it is extremely important to adhere to the dosage, and observe the frequency of feeding according to the attached instructions.

Lighting should be bright but diffused. It is not desirable to get direct sunlight on the leaves of the plant, as this can cause burns and destroy the plant. The best place to place flowers is on the windowsill on the west or east side of the house. If the amount of light is not enough, in this case it is necessary to organize supplementary lighting with fluorescent lamps.

In the room where gloxinia is located, it is recommended to maintain a constant temperature, as the plant reacts negatively to temperature changes and drafts. During the period of active growth, the optimum temperature will be +18 degrees. During the dormant period, the temperature in the room should not exceed +10 degrees.

Seed collection

In order to get seeds at home, flowers must be pollinated. During flowering with a soft brush, touch the pistils of each flower. It is recommended to repeat this procedure for several days in a row. After the petals fall off, a seed pod forms in the center of the flower. From the moment of its appearance to disclosure, it takes about a week. The boxes are cut and lowered into a glass. From a bursting box, seeds that have a brown color will spill into it. Harvested seeds do not require any treatment before sowing.

Gloxinia – dormant period

Young plants do not need rest, plants aged 1 year need rest. You can understand that the plant needs rest by drying out the leaves – drying starts from the lower leaves and after a while all the leaves completely dry out. If the top remains green during the drying process, you need to let it dry. You can’t cut it. In the process of drying out, all the nutrients from the green mass pass to the tuber, and the plant, thus, gains strength, preparing for wintering.

During the preparation of the plant for hibernation, it is necessary to reduce the amount of watering, and stop fertilizing. The container with the plant must be moved to a dark place.

After complete drying of the green mass, it is necessary to prepare the tuber for storage. You can store tubers in two ways:

Method 1

The tuber must be removed from the soil, washed under running water and dried, then placed in a plastic bag filled with wet peat . Several holes must be made in the bag so that air can enter the bag. This will prevent condensation from accumulating. The package with the tuber is removed in a cool room without access to light. Every month, the tuber must be inspected for the presence of mold.

Method 2

If the tuber has not yet had time to develop well, it is left for the winter in a pot. After the death of all the green mass, we place the pot in a tight plastic bag with several holes, and put it in a dark, cool room. If the air in the room is too dry, then the soil sometimes needs to be slightly moistened.

Growing Gloxinia from a Leaf

To grow a plant from a leaf, you need to select a healthy, undamaged large leaf and cut it with a sharp blade from the bottom across the large veins. The sheet is laid with cuts on moist soil, pressed and covered with polyethylene and placed in a room with a temperature of 23-26 degrees.

Growing Gloxinia from a Leaf

Polyethylene is removed daily for airing and moisturizing. After a while, roots appear in the places of the cut, and then small tubers.

You can also divide the leaf across into several parts and plant each of them in the soil for rooting. The soil should be loose and light. A container with leaf particles is covered with polyethylene, creating a greenhouse. After rooting, they are seated in containers intended for further growth.

Important care points

For the successful cultivation of Gloxinia, several rules for growing and caring must be observed:

  • The plant prefers space. A large cluster of plants in one place can cause the development of fungal diseases.
  • The optimum temperature in the room is +20 degrees.
  • The place to place the plant should be brightly lit, but without direct sunlight on the flower.
  • Watering should be done as the topsoil dries out. 30 minutes after watering, remove excess moisture from the pan. During the hot season, watering is carried out in the evening.
  • Remove dried inflorescences and leaves.

Pests and diseases

Gloxinia can be prone to the following diseases:

late blight

The causes of a fungal disease can be:

  • improper selection of soil;
  • excessive watering;
  • stagnation of moisture in the soil;
  • increased air humidity;
  • low room temperature.

Signs of the disease are the appearance of brown spots on the leaves of the plant. The affected plant must be destroyed. For the purpose of prevention, it is recommended to treat the plant with the preparation “Polycarbocid”.

Gray rot

The disease occurs due to improper care of the plant. Signs of this disease are slow growth and poor development of the plant. To stop the further development of the disease on tubers, damaged areas are removed, leaving only healthy tissues. The cut is dried, treated with crushed coal and planted in new soil.


This disease occurs when a plant is planted in contaminated soil. The basal neck darkens, and the plant begins to creep along the ground. At the first signs of the disease, the plant is treated with copper sulphate. Stop watering for a while.

powdery mildew

Signs of this disease are a gray coating on the leaves. The cause of the disease is excessive humidity and sudden changes in temperature. At the initial stage of the disease, the plant is treated with Vectra. If most of the plant is affected, it must be destroyed.

Pests affecting Gloxinia are:


This insect feeds on cell sap. When a plant is affected by this insect, a sticky coating appears on the leaves of the plant. The leaves are twisted, resulting in their deformation. With a massive invasion of insects, the plant is treated with the preparation “Confidor”.

spider mite

A thin web appears on the leaves of the plant as signs of damage to the plant by a spider mite. In places where the insect sucks the juice from the cells of the plant, grayish spots appear.

To destroy the pest, the leaves of the plant are wiped with a sponge dipped in a solution of laundry soap or the Neoron preparation is used. Treatment with the drug is carried out twice. Take a week break between treatments.


A sign of the appearance of a pest will be the wilting of the leaves of the plant and the appearance of light stripes on them. The pest feeds on plant sap and nectar. You can destroy these pests with the help of the drug “Aktellik”.

Gloxinia is a luxurious, exquisite flower, which, subject to the recommendations, can be grown even by novice flower growers.
