Gomfrena: planting and care, growing from seeds in the open field, photo
Gomphrena (lat.Gomphrena) - a genus of flowering plants of the Amaranth family, common in the tropical zones of both the Northern and Southern Hemispheres. The French botanist Delachen, who described the gomphrene, indicated that Pliny gave the plant the name, and Karl Linnaeus introduced the gomphrene to the "Species plantarum" under this name. The largest number of different representatives of this genus can be found in South America, in total there are about a hundred species in the genus. Some of them are grown as houseplants.

- The soil: not too fertile neutral reaction.
- Watering: moderate and only in dry season.
- Top dressing: 2-3 times a season with a complex mineral fertilizer with a low nitrogen content.
- Reproduction: seed.

Read more about the cultivation of gomphrene below.
The genus Gomfren includes both annual and perennial grasses with erect or erect stems, opposite sessile or petiolate leaves with a solid edge. The flowers of these plants, white, red, purple, pink, lilac, blue or yellow, often unevenly colored, are collected in a capitate inflorescence. The fruit of gomphrene is a non-opening achene with flattened, smooth seeds.
In our climate, perennial plant species are grown in annual crops. Gomfrena is distinguished by its unpretentiousness and high decorative qualities.
Growing from seeds
When to sow for seedlings
In the middle lane, the cultivation of gomphrene from seeds is carried out exclusively in a seedling way, since the seeds of a plant sown directly into the ground may not germinate, and the ripening period for this flower is long. Sowing gomphrenic seedlings is done in early March.

But first, you need to prepare the seeds of gomphrene for planting, and it will take you 10 days: you need to pour the seeds placed in a glass jar with warm water for three days in a row in the morning. On the fourth day, pour the water with the seeds onto a sieve, rinse the seeds under running water, rinse the jar, put the seeds in it, close the nylon lid and keep the jar with seeds for a week in the vegetable drawer of the refrigerator.
How to sow seeds
Mix equal parts of All-Purpose Vegetable Seedling Soil and vermiculite or coarse sand and moisten the mixture well to keep it moist but not wet. Place the substrate in a container, preferably in cassettes. Press down well and water the substrate again, because next time you will not be able to moisten the soil soon. Remove the cold seeds from the jar, spread them on the surface at a distance from each other, press them against the substrate, cover the crops with foil or glass and keep them under bright diffused light at a temperature of 20-22 ° C.
Seedlings may appear in 2-2.5 weeks, but if you apply the bottom heating, the seeds will begin to germinate in three days. When seedlings appear, the cover is removed, and when the seedlings that are grown in a common container are 2-2.5 weeks old, they are dived into separate pots with a diameter of 5-7 cm or into more spacious dishes. As soon as the seedlings recover from the pick, water it with a weak solution of mineral fertilizer.
Keep the substrate in a slightly damp state, avoiding waterlogging, otherwise the seedlings may fall from the black leg - a harmful fungal disease that affects crops precisely during the seedling period.
Do not forget to carefully loosen the substrate around the seedlings after watering, and if you find alarming symptoms of the disease, remove suspicious specimens, sprinkle the surface of the substrate with wood ash and stop watering for a while.
When to plant in the ground
Gomfren should be planted in a flower garden when the threat of a return of night frosts has already passed, the soil warms up and warm weather sets in, that is, in late May or early July. Find the sunniest place in your garden, protected from wind and drafts. Gomphren prefers soil that is not very fertile and neutral.
How to plant
Dig up the area before planting gomphrene, but you do not need to apply fertilizer to the soil. Level the surface and dig holes, observing the distance between them for low-growing varieties - 15-20 cm, and for tall varieties - 30-35 cm. The depth of the hole should be such that the seedling will fit in it together with the earthen clod. Transfer the seedlings into the holes, place them in the center, being careful not to damage the roots, and fill the remaining space with earth. After planting, compact the soil around the seedlings and water them.
Planting a gomphrene and caring for it does not require any special skills or professional training from you. The gomphren plant is unpretentious and will require a minimum of attention and very modest efforts to keep it in optimal shape. You will need to water the gomphrena, loosen the soil around it, weed out the weeds, apply top dressing and trim it slightly so that the bushes have a neat outline. By the way, gomphrene is attractive in cutting, and the more often you cut it for bouquets, the more luxuriant it will bloom and grow thicker.
Watering and feeding
Gomphren needs watering only in dry weather, and soil moisture should be moderate: the plant will calmly react to the fact that you forgot to water it, but excessive or too frequent watering can cause the development of a fungal disease, especially in low air temperatures.
In the season with normal rainfall, gomfren is not watered at all, however, the next day after rain, it is advisable to loosen the soil around the bushes and remove weeds.
Top dressing on the site with gomphrene also needs to be applied with caution, since an excess of nutrition, especially nitrogen, can provoke a violent growth of green mass, but you may not wait for flowering.

Diseases and pests
Gomphrena is ill only from stagnant water in the roots, and we have already informed you about this. For the rest, it is a very strong plant, not damaged by any parasites, except for aphids, which can move to gomfren from other plants.
They destroy aphids with an insecticidal preparation: do not waste time trying to fight the pest with folk remedies.
Types and varieties
Of such a variety of gomphrene species, only three of them are grown in culture.
The plant is from 15 to 40 cm high with entire, glaucous from pubescence leaves on short petioles and red, pink, white, lilac, crimson or purple spherical heads up to 4 cm in diameter. Flowering begins in July and ends before frost. Known varieties of spherical gomphrene:
- Bright Border - Plants up to 30 cm high, painted in various shades of pink, up to pink-carmine;
- Buddy - a series of varieties up to 15 cm high in white, purple and pink colors.

Also popular are the varieties of Gomphrene globose globose, Raspberry Berry, Fireworks, Pompon and a series of Pixie mix and Gnome varieties.
Or gomphrena golden-flowered - this species in culture not so long ago. It resembles a spherical gomphrene, but the Haage gomphrene inflorescences are larger, and they are colored red and orange. This species is even more thermophilic and does not always bloom in cold summer conditions.

Often grown in suspended structures. Its stems with elongated leaves spread over the area, forming a carpet, and golden-orange buds and carnation-shaped inflorescences look harmoniously and effectively against their background. A popular variety of this type:
- Pink Pinheads - Plants with bright pink flowers that retain their color even after drying, therefore they are often used for winter bouquets.

Seed planting in open ground
For warm regions, there is no need to deal with Nemesia seedlings. After planting small seeds, there is a high chance of good growth and flowering of the annual. Caring for plants is simple, one of the main requirements is sufficient watering.
Nemesia is a thermophilic plant native to South Africa. Frosts, sharp fluctuations in temperature negatively affect the germination and state of the planting material.
In open ground, seeds are sown no earlier than in late April - early May. It is impossible to determine the exact date: the grower should take into account the weather forecast for his region. The absence of recurrent frosts, the temperature not less than + 16..18 degrees - are prerequisites for sowing "grains".
Location selection and lighting
Nemesia prefers areas with no shade. Abundant flowering is possible only with enough light.
For planting Nemesia, an area with good quality soil is chosen. The plant does not tolerate a moisture deficit, but sowing seeds or seedlings in the lowlands is not worth it: with excessive accumulation of moisture, plant decay begins.
- you cannot sow seeds too close to each other: nemesia is actively growing, with thickened plantings, the bushes touch shoots and leaves. The result is negative - the transition of fungal diseases and the movement of pests through neighboring plants, weak growth, less abundant flowering. Despite the root system, nutritional deficiencies are still felt
- sow seeds optimally at a distance of about 20 cm between adjacent elements
- before planting a beautifully flowering species, be sure to dig up the soil, remove weeds, and add a little peat. It is important to break up the clods well so that the earth is soft and loose.
- sowing seeds is carried out in good weather, in the absence of fog and rain. Optimally, a sunny, but not very hot day, so that the soil dries out gradually, and not over the course of a day. You can water the ground with a solution of potassium permanganate (medium strength) to prevent fungal infections.
Pests and diseases
The humid environment preferred by nemesia often provokes the development of root rot and other fungal diseases. As a rule, such diseases are difficult to treat, so it is easier to dig up the bush and remove it so that neighboring plants do not become infected.
As a preventive measure, in April or May, it is necessary to treat the bushes with fungicides:
- bordeaux liquid.
Sometimes flowers infect spider mites and other pests. Therefore, it is necessary to periodically inspect the plants and carry out treatments with insecticides or folk remedies (infusion of mustard powder, chili peppers, onion husks, chopped garlic and others).
