Garden hibiscus is a real decoration of any site. Unpretentious in care, it will delight the owner with its exotic flowers for more than one year.

Hibiscus propagates most often - by cuttings and seeds. These methods are effective, simple: even a novice florist can handle them.

In the article, we will consider how to properly prepare the soil and choose a place for planting, how to root cuttings, and also how to care for a tree or herb planted in open ground.

We will also analyze possible problems during cultivation.

Best time to breed

The choice of the season directly depends on the breeding method. So, the sowing of seeds is carried out from January to March. During winter and spring, seedlings will grow, gain strength, and strengthen. In open ground, seedlings are planted in mid-May. Cuttings are cut from April to August.

The most favorable month is May: the plant is full of vitality, is actively developing, the air temperature is quite high, but there is still no summer heat, plenty of soft sunlight. Over the summer, the seedlings will be able to take root and get stronger.

Soil preparation and site selection

  1. Earth.

    For sowing seeds and rooting a cuttings of garden hibiscus, a peat-based substrate is suitable:

    • a mixture of peat and moss - sphagnum;
    • a mixture of peat and perlite;
    • a mixture of garden soil, peat, coarse sand in equal proportions.

    Growing hibiscus outdoors also requires light and permeable soil rich in organic matter. For example, sod, leafy soil, humus, coarse sand in a ratio of 2: 2: 1: 1. Alternatively: 5% perlite, 45% hardwood bark, 50% peat.

  2. A place.

    The best place for garden hibiscus on the site is partial shade, it does not tolerate direct bright sunlight. But you cannot plant it in absolute shade. Also, the place must be protected from drafts.

How to plant the seeds correctly?

The seed method makes it possible to get a flowering plant only after 3 years. First you need to collect and prepare the seeds. After the hibiscus has faded, pods containing seeds begin to ripen. Ripening indicator - the pods begin to brown. At any moment, they can open up and fall to the ground.

Before collecting seeds, the plant must be covered with material or paper to avoid spilling. Before sowing, the seeds must be soaked for 10 hours in a growth stimulator.

Step-by-step landing instructions:

  1. Prepare what is needed for sowing: container, substrate, drainage (expanded clay, pebbles, broken brick), seeds, a spray bottle with water, glass or plastic wrap.
  2. Fill the bottom of the container with drainage, then a layer of soil.
  3. The soil should be well moistened.
  4. The seeds are spread over the surface at a distance of 0.5 cm from each other, and they are sprinkled on top with a thin layer of substrate so that the seeds are buried by 5 mm.
  5. Moisten the top layer liberally with a spray bottle.
  6. The pot is covered with glass or polyethylene, placed in a warm, bright place, but without direct sunlight. The recommended temperature for keeping is + 25C - + 27C. The first shoots will appear in 2 - 3 weeks.
  7. It is necessary to maintain constant humidity in the greenhouse, do not forget to ventilate it and regularly spray the seeds and soil.
  8. When the first leaves appear on the seedlings, they must be planted in individual pots.
  9. In mid-May, seedlings are planted in open ground.

Important! The method of propagation of garden hibiscus by seeds will not guarantee the preservation of all characteristics (color, variegation) of the mother plant. It is possible to preserve all the characteristics only when the plant is propagated by cuttings.

How to propagate by cuttings?

The method of propagation by cuttings is a favorite among flower growers, it is suitable for both tree and herbal hibiscus. The stalk will give roots in a month - one and a half, and a plant grown from a cuttings will bloom one year after rooting.

For grafting, it is necessary to cut off a young semi-lignified shoot from the upper part of the bush (length - 10 - 15 cm, there must be 2 - 3 internodes on it), cut it obliquely from the mother plant with a clean knife or pruner, remove the lower leaves, and cut the upper ones in half ... Shorten the top of the shoot with a straight cut.

Rooting in water

Step-by-step landing instructions:

  1. Prepare everything you need: a container made of dark plastic or glass, a handle, an activated carbon tablet, a little growth stimulator, a greenhouse.
  2. Fill the container with settled water at room temperature (2/3).
  3. Add an activated carbon tablet to the water and dissolve the root formation stimulant in it.
  4. Dip the stalk into the water.
  5. From above, the container with the shoot must be covered with a greenhouse.
  6. Place the vessel in a warm (+ 20C - + 25C) and bright place (but without direct sunlight).
  7. Sometimes the greenhouse needs to be opened slightly, the drops of condensate must be shaken off its walls so that decay processes do not begin.
  8. After the roots grow to 2 - 3 cm, they can be planted in the ground.

Reference. If there is no mini - greenhouse, then it can be made from a plastic bottle by cutting it. A plastic bag is also suitable, which is recommended to be tightened with an elastic band to maintain a high level of humidity. You can also use regular plastic food containers, but first make sure that the lid fits snugly against the container.

Rooting in the ground

Step-by-step landing instructions:

  1. Prepare everything you need: a container (200 - 500ml, there must be a drainage hole), drainage (expanded clay, pebbles, broken brick), a substrate, a shank, a root formation stimulator, a pencil (wooden stick), a watering can with water.
  2. Cover the bottom of the pot with expanded clay (2 - 3 cm), fill the rest of the volume with the substrate.
  3. Water the soil abundantly. Allow water to drain.
  4. Use a pencil or stick to make a depression of 3 - 5 cm in the substrate.
  5. Pour ½ tsp into the well. a root formation stimulator.
  6. Lower the handle into the recess.
  7. Sprinkle it with substrate and crush it for better fixation.
  8. Cover with mini greenhouse on top.
  9. Place the vessel in a warm (+ 20C - + 25C) and bright place (but without direct sunlight).
  10. Systematically, the greenhouse needs to be opened slightly, and condensate drops should be shaken off its walls.
  11. After about 1.5 months, the stalk will release the roots, and it can be transplanted into open ground by the transfer method. But it will still be better if the plant spends the first winter indoors (read about preparing for winter and hibiscus wintering here).

Attention! To check whether the stalk is rooted in the ground, it is enough to lightly pull on its top or leaves: if the stalk is rooted, it will sit firmly in the ground.

How to care for a tree or herbaceous plant planted outdoors?

How to grow hibiscus after planting in open ground so that it becomes a garden decoration? After the garden hibiscus has been planted on the site, it needs to be cared for as an adult plant. Systematic loosening of the topsoil, removal of weeds, regular watering (in hot and dry summers, watering should be daily) - this is what the plant needs.

Twice a month, from June to September, garden hibiscus needs to be fed with fertilizers that are high in nitrogen and phosphorus., and in the fall - fertilizers with potassium. Do not forget about regularly pruning the plant. Read about spring garden hibiscus pruning here.

Possible growing problems

  • The rooted stalk withers after transplanting into the ground.

    When planting a young plant, its root system was disrupted. We'll have to cut the hibiscus again, since there is practically no chance of survival for such a cutting. This phenomenon can be prevented if the cutting is transplanted by the transshipment method: remove the plant from the old pot and, without shaking off the earthen coma, place it in the earthen hole.

  • The plant did not bloom as expected.Garden hibiscus needs regular pruning for systematic and abundant flowering.
  • Young garden hibiscus shows signs of infectious diseases (rot, powdery spots, etc.). To prevent this phenomenon, it is recommended to disinfect the soil, the pot in which the cuttings will be planted (treatment with fungicides, heat treatment). You can also immerse the seeds in a weak solution of potassium permanganate for a short time before soaking them in a growth stimulant solution.

The two breeding methods discussed in the article are simple and reliable. The choice of one of them is a matter of taste, desire, and the possibilities of the gardener. But in any case, the summer cottage will be decorated with a young, unpretentious, flowering plant.
