Plant description

Lobelia is a perennial flower, but in the conditions of central Russia it is grown in open ground as an annual plant. It looks great as a curb along the garden path, along the contour of a flower garden or pond, on an alpine hill and in flowerpots. It is also good as a groundcover in carpeted planting and as an ampelous plant in hanging baskets. Harmonious partners: petunia, balsamine, cloves, verbena, rudbeckia, pelargonium, salvia and other garden flowers.

At the end of autumn, a flower can be dug up, planted in pots and stored in a greenhouse or on a balcony so that in summer, in the second round, planted in the garden. The plant during the wintering period is poorly developed, but, subsequently, it will bloom more abundantly.

The main conditions for successful cultivation and abundant flowering of plants:

  1. Loose and light, not very fertile soil (sandy loamy, loamy soil).
  2. Landing in a well-lit, sunny place.
  3. Regular watering - the plant loves moisture.
  4. Dosed fertilizing with mineral fertilizers.
  5. Pinching or cutting seedlings, pruning adult plants for better tillering.

Sowing seeds for seedlings

It is better to start sowing seeds from the end of February, or at any time throughout March. True, some gardeners practice flower sowing in December-January. But if there is no possibility of additional illumination, it is advisable not to rush when sowing lobelia for seedlings: seedlings in this case develop slowly, and when there is a lack of illumination, they are pulled up. A flower planted in March and grown only in natural light is more viable and compact, less often affected by the disease "black leg".

Proper cultivation and care of seedlings will contribute to its abundant flowering.

The seeds are small, dusty - for uniformity, they are often mixed with sand. Seeds are planted in purchased soil for seedlings or in a soil mixture prepared from autumn, consisting of turf garden soil, compost (humus), peat and river sand. To normalize the acidity of the soil substrate, you can add dolomite flour or lime.

You can purchase granular seeds that are conveniently planted in peat tablets and cassettes - so you get rid of the time-consuming stage of the pick.

The sequence of planting a flower for seedlings:

  1. The container for planting is filled with a soil substrate, which is slightly tamped, watered and aged for 24 hours. Lobelia seedlings feel best in a wide and shallow tray equipped with drainage holes. A fungicide can be added to the water for primary irrigation of land for seedlings.
  2. Seeds are placed on a sheet of paper bent by a corner and, gently tapping on it, they are poured onto the prepared soil, evenly distributing them.
  3. After sowing, the seeds are by no means sprinkled with earth, but sprayed with a very weak solution of potassium permanganate from the spray gun.
  4. A dish with seedlings is covered with glass and placed in a warm place.

Soil substrate for sowing seedlings can be prepared from a mixture of garden soil and vermiculite. Vermiculite increases the porosity and friability of the soil, normalizes its moisture. It also protects the root system of plants from temperature changes in the environment, neutralizes soils with high acidity.

Proper seedling care

Every day, it is recommended to ventilate the seedlings: raise the glass, wipe the condensate from it and, turning it over, again cover it with a bowl. As soon as the first shoots appear, and this happens a week and a half after planting, it is advisable to remove the glass, move the bowl with seedlings into the "greenhouse" - a transparent plastic bag, and, tying it up, put it in a well-lit place, but not under direct sunlight . The package must be removed every day, shake off condensation from it and again wrap the seedlings.

At a temperature of 20 to 25 degrees, seedlings may appear earlier - after about a week. But, so that they do not stretch too much and gradually harden, it is recommended to move the seedling trays in the afternoon to a glazed balcony or loggia, where the temperature is low and there is enough light. At night, it is better to return the seedlings to the house, providing additional illumination in the evenings, as well as in cloudy and rainy periods.

Humidification of crops is best done from below, pouring a little water into the pan, because the likelihood of mold formation on the surface of the earth and decay of seedlings. But you can water from above, very carefully: from a teaspoon or a disposable syringe. If the mold still forms, it is carefully removed and sprinkled with a thin layer of crushed activated carbon or pre-washed and calcined sand. To prevent diseases, it is necessary to ensure that the soil is loose and moderately dry, but it must not be allowed to dry out either - moderate watering is recommended for lobelia.

Dive into the ground

The grown seedlings dive - they are planted in small heaps, grabbing with a coffee spoon several plants along with the soil and moving to a separate container. Before picking, it is recommended to moisten the soil in the tray well, so that it is more convenient to divide the densely grown seedlings into piles. When transplanting between groups of plants, an interval of about 2-3 cm is left, the soil is lightly tamped with fingers and then watered. After a pick, lobelia will begin to grow rapidly, when the sprouts reach 3 cm, it is recommended to cut them a few mm - so they will shrub better.

Lobelia dive must be done very carefully, moving the small bushes of seedlings from the tray into separate containers

To water the lobelia seedlings, use a disposable syringe or a small spoon so that drops of water do not fall on young leaves

A plant is planted from temporary containers in open ground at the beginning of June, observing the distance between the bushes of 10-15 cm. Transplantation is carried out according to the same principle as diving: in small groups, capturing the plants together with the soil with a small shovel or construction spatula. For planting, choose a sunny or partial shade of the garden with humus-rich moist soil. An excessively fertile land is bad for lobelia - the plant grows lush greenery and sparsely blooms.

Quite often resort to cutting bushes to a height of 5 cm in the middle of summer, which leads to its growth and a new wave of flowering. At this stage, the plants can be slightly fed approximately once a week with water-soluble mineral fertilizers.

Option # 2 - in hanging baskets

Ampelic species are spectacular in hanging spherical baskets - they form a continuous floral cover that completely hides the wire or vine frame. The easiest option for planting lobelia in the form of a flower basket is the use of coconut inserts, in which holes are made and the plant is planted on the outside of the basket, after filling it with soil mixture.

Sphagnum moss is also used as an insert, which is pre-soaked, squeezed and laid out in the shape of a basket from the inside. Then, soil mixed with peat and long-acting fertilizers is poured into the basket. In the upper part of the basket, erect types of lobelia are planted, ampel varieties are planted in a circle, observing the distances between the bushes. With this type of planting, you can combine the plant with petunias, phlox, pelargonium, ivy.

Option # 3 - in decorative flowerpots

The flower looks amazing in decorative flowerpots, it is only important to properly match it with companion plants. If you use low flowers paired with lobelia, you can diversify the composition in a round pot by planting plants with different texture of foliage and the size of inflorescences.

Wide flowerpots of considerable diameter of a laconic configuration or equipped with a constriction and a pedestal are ideally suited for such a landing. The flower arrangement will be more dynamic if you combine a compact look with direct-growing plants.

Option # 4 - flower tower of flowerpots

The plant looks advantageous in a vertical container gardening planted in a flower tower or the so-called "whatnot" of pots. To form such a composition, you can take from 3 to 5 terracotta or white flowerpots with a difference in diameter of about 7 cm. After filling the bottom pot with earth, a rebar is installed, which is buried in the garden soil through the drainage hole for the stability of the flower tower.
