Geraniums: Home Care, Replanting And Propagation, Species

Few flower growers know that it is possible to grow geraniums (pelargoniums) with inflorescences of various shades and scents under room conditions. The grafting of geraniums will help you, thanks to which you can feel like a real creator.

Only absolutely healthy young geranium bushes can be used for grafting. This is best done in spring. As the basis, you can take any strong bush of pelargonium, the age of which should be at least 1 year.

Cut off the top part of the powerful stem, then make a cut in it "tick" about 20 mm. Insert the cut into the resulting cut scion, which is prepared in advance. Note that the cuttings of the scion and scion should touch each other very tightly. The grafting point should be secured with a soft woolen thread or a piece of plastic film. A transparent plastic bag should be placed on top of the bush.

Whether or not the grafting was successful can be determined after one week.

Growing summary

Geraniums: home care, replanting and propagation, species

  1. Flowering. Geraniums are capable of blooming throughout the year.
  2. Brightness. Needs plenty of bright light, so a south-facing window sill is great for the flower.

  3. Temperature regime. Throughout the growing season, the flower grows normally at normal room temperature. At the same time, during the dormant period, the temperature should be about 15 degrees.
  4. Pouring. During the vegetation period, the bush is provided with abundant watering, and it is carried out immediately after the top layer of substrate in the pot has dried out.

    In winter time the plant is not watered.

  5. Air humidity. It grows normally at the level of air humidity that is typical for living spaces.
  6. Fertilizer. Fertilize geraniums from the last days of March to the second half of November twice a month, using a complex mineral fertilizer for flowering houseplants.

  7. Storming period. From the end of November until the first days of spring.
  8. Potting. Perform the procedure only when necessary when the root system becomes very crowded in the pot. Repotting is recommended at the beginning of the growing season.

  9. Trimming. It is carried out every autumn. To do this, all stems must be shortened so that they are left with 6 or 7 leaf plates.
  10. Pinching. It is recommended that all shoots be pruned above the fourth or fifth leaf plate.

  11. Propagation. By seeds and cuttings.
  12. Pests. Whiteflies, aphids and spider mites.
  13. Diseases.

    Botrytis, leaf spot, bacteriosis, black rot, rust, root rot, and viruses.

The pelargonium plant (Pelargonium) is part of the Geranium family and is native to South Africa. This genus includes about 400 forms and species of pelargonium, and among them there are both annuals and perennials. In European countries, geraniums began to be cultivated in the late 15th century or early 16th century. Flowering geraniums, or pelargoniums, are related to common geraniums and meadow geraniums.

Those species that are cultivated at home, experts have been grouped under the general name "indoor geraniums".

Peculiarities of growing the indoor geranium

Geraniums: home care, replanting and propagation, species

The indoor geranium is quite popular among flower growers. The fact is that it is distinguished by its long and spectacular blooming, and also by its undemanding care and cultivation conditions. However, there are a few rules that an inexperienced florist, who decided to decorate his house with pelargonium, should definitely know, namely:

  1. In winter time, the flower prefers to stay in a cool place.

    But it should be remembered that the temperature in the room should not fall below 10 degrees.

  2. The plant needs plenty of sunlight, which is why it feels best on a window sill with a southern orientation.
  3. Because it comes from South Africa, it can bloom all year round if it gets enough light and nutrients.
  4. For a more lush and branched shrub, do not forget to prune the shoots in time.
  5. Do not forget to cut the faded inflorescences.

  6. Virtually all Pelargonium species and varieties need systematic pruning.

General rules

Growing indoor pelargoniums is not difficult at all. A moderately fertile substrate must be used for planting in order for the bush to bloom lushly rather than build up green mass. During planting or transplanting, do not forget to make a thick layer of drainage on the bottom of the container, for this purpose it is recommended to use coarse expanded clay. Watering should be abundant, it is carried out after the top layer of soil mixture dries up.

In winter the flower is watered very rarely.

Wetting the foliage of geraniums from a sprayer is not necessary because it responds best to dry fresh air. This is why experienced experts recommend moving the shrub to a balcony in the summertime. The plant needs plenty of sunlight, with direct sunlight only doing it good, not harm. However, on hot summer days at midday, it is still recommended to shade the flower from direct sunlight.

In the warm season, the flower feels normal at almost any air temperature. In wintertime, however, it is recommended to put the bush in a cool place (around 15 degrees).

Feed indoor geraniums once every 15 days (from the last days of March to the middle of November). And liquid fertilizer is used for this.

A solution of iodine is excellent for fertilizing pelargoniums.

To prepare it, combine 1 liter of water and one drop of iodine. For 1 bush take 50 milligrams of the solution, and pour it into the pot very carefully along the walls. Do not overdo it with iodine solution, as this can burn the root system of the flower. Thanks to this fertilizer, the flowering in the pelargonium will be long and lush. Remember that you should not fertilize the flower with fresh organic fertilizer.

Geranium transplanting

Geraniums: home care, replanting and propagation, species

House geraniums are hard to transplant and should only be transplanted if absolutely necessary. For example, the bush should be replanted if its roots stick out of drainage holes.

The beginning of the geranium's growing season is in early spring, and this is when experts advise that it should be transplanted or planted. Pay attention to the fact that the new pot in diameter should be larger than the old one by about 20 millimeters. If the container is very large, the green mass will actively grow to the detriment of flowering.

Pelargoniums are pruned in the fall. To do this, each shoot is shortened so that it has 6 or 7 leaf plates left on it. Cut out all stems that grow from the axils of the leaves and not from the root. If the bush has grown strongly again over the winter, cut it back again and only a few buds should remain on the shoots.

The remaining cuttings can then be rooted and potted if desired.

To make the bush more lush, branchy and flower abundantly, remember to prune the shoots above the fourth or fifth leaf plate. In December and January, trimming is not advisable.


Growing from seed

Geraniums: home care, replanting and propagation, species

House geraniums can easily be raised from seed. Seeds bought at a specialized store have a high germination rate and give ample sprouts.

Collect the seed material by your own hands from your flowers is undesirable. The fact is that seeds collected from hybrid varieties are unable to retain the varietal characteristics of the parent plant.

To sow seeds, use a moist and loose soil mixture consisting of sand, peat and turf soil (1:1:2). The seeds should be covered with a layer of sand or the same substrate, with a thickness of about 25 mm. Seeds are watered from a sprayer, and the container is covered with a transparent film or glass from above.

In order to prevent the development of "black leg", disinfect the soil mixture in advance by pouring it with a solution of manganese potassium pink. Do not forget to systematically water the crops and remove condensation from the cover. The optimum air temperature for seedling emergence is 18 to 22 degrees.

After the first seedlings have emerged, remove the cover and move the seedlings to a well-lit and cool (16 to 20 degrees) place. After 6-8 weeks, the seedlings will have two or three true leaves each.

At this time it is recommended to sprout them into separate pots. Once the bush has 5 or 6 leaves, it is advisable to prune the shoots to make the bush more vigorous.

Preparing cuttings can be done at any time of year, but spring is the best time. Cuttings can vary in length from 5 to 7 centimeters and each should have 2 or 3 leaf plates.

Leave the cuttings out in the fresh air for 24 hours so they have time to dry well.

Treat the cutting area with powdered charcoal, then plant the cuttings in a small pot filled with loose substrate. It is not uncommon to use sand for rooting geranium cuttings. In this case, it is recommended to make sure that it is always a little damp. When watering, try not to get water on the shoots and foliage, as this can lead to rot. Do not cover the cuttings from above.

After the cuttings grow roots, transplant them into permanent pots. Take note that cuttings root best at 20 to 22 degrees.


Diseases and Pests of Geraniums

Geraniums: home care, replanting and propagation, species


Geranium is highly resistant to disease. However, it can still get sick, and most often this is due to improper care.

Sometimes it happens that a young bush has a black stalk (black rot). It is impossible to cure the diseased plant. Therefore, it is burned and the substrate is disinfected or thrown away. To prevent root, black and grey rot, do not allow the substrate to become stagnant.


Whiteflies, mites or aphids can settle on the flower.

If you find aphids or mites, wash the leaves as soon as possible using tobacco or chamomile infusion mixed with green soap and paying particular attention to the underside of the leaves. Wait two to three hours and rinse the bush with clean water.

To save geraniums from whiteflies, it should be sprayed alternately with solutions of the following preparations: Confidor, Fufanon, Zubr and Actellic. The thing is that it is quite difficult to exterminate adults and whitefly larvae.

The geranium leaves turn yellow, red, dry, curl up.

.. Pelargonium diseases and pests

Why do geraniums turn yellow

Geraniums: home care, replanting and propagation, species

Yellowing of pelargonium leaves can be observed for several reasons:

  • yellowing and withering of the edges of the leaf plates means that the bush needs watering;
  • if the foliage is yellowing and the bush itself is sluggish, there is constant fluid stagnation in the soil;
  • the bush yellowing and falling off of the lower leaves is due to poor light;
  • the root system is tight in the pot;
  • the bush was recently transplanted or moved to another location.

Why geraniums don't bloom

Geraniums: home care, replanting and propagation, species

Pelargoniums usually refuse to bloom for the following reasons:

  • the room is cold or the bush lacks sunlight, to remedy the situation, shine it up with daylight lamps;
  • the substrate has too many nutrients (we recommend buying a special soil mixture for geraniums for the flower, or you can also make it yourself using the special recipe described above);
  • a pot that is too big;
  • the bush is not regularly trimmed (trimming makes the geranium grow lush and bloom abundantly);
  • not timely fertilizing.

Why are the geraniums not blooming?!

Why is the geranium shrub withered

Geraniums: home care, replanting and propagation, species

If only the leaf tips of the bush wither, this means it needs watering.

Rust can also be the cause of shrub desiccation. This fungal disease first causes brownish-red spots to form on the leaves and then causes them to wither and fall off. Treat the bush with a solution of Bordeaux mixture (5%). Instead, two phytosporin treatments can be made 1-1.5 weeks apart.
