About 200 species of gladioli are grown in the world today. The plant has a vertical, unbranched stem, its height can reach from 50 to 140 cm. The plant has xiphoid leaves, flowers can be collected in spike-shaped inflorescences, one or two-sided, they can be loose or dense. Gladiolus flowers have funnel-shaped perianths, consist of six irregular lobes, fused at the base. The fruit of the plant looks like a tricuspid capsule. Gladiolus seeds are round in shape, their color is brown.

How to plant gladioli

The correct planting of gladioli is a rather troublesome business and requires certain knowledge: you need to know when to germinate gladioli, how to choose the right place for planting, what soil composition will be most optimal for growing these beautiful flowers.

First of all, we will consider the question of soil. In principle, any cultivated soils are suitable for plants, but it is preferable to choose well-fertilized sandy loam light soils for growing them. Sand should be added to clay soil, lime and humus should be added before autumn digging. The introduction of fresh manure is undesirable - the plant will produce many leaves, but its flowering may be weak.

In the spring, ammonium nitrate and superphosphate are additionally introduced into the soil, at the rate of 15 grams of each fertilizer per 1 square meter, as well as potassium sulfate - up to 30 g per square meter. It will be nice to add wood ash to the soil.

It is very important to choose a well-lit area for planting, it is advisable to orient the beds in the east-west direction. Bulbs should be planted no earlier than the soil temperature rises to +10 degrees, usually in late spring. Planted at fairly low temperatures in moist soil, the bulbs give a very rapid growth of the root system, which during the summer will enable the normal development of the plant and create conditions for its abundant flowering.

Experienced growers share a secret: in order to get good flowering, gladioli should be planted annually in the same place - the plants will be at great risk of disease.

Undesirable predecessors for gladioli are asters, phloxes, and other plants prone to infection with fungal infections. It is good if there is an opportunity to plant gladioli in the place where onions, garlic, and cucumbers grew in the previous year.

How to prepare bulbs and when to germinate gladioli

The preparation of the bulbs consists in their careful sorting, selection of diseased and damaged ones. All problem areas on the bulbs should be cleaned, covered with crushed coal. When purchasing new bulbs, one should avoid those that have putrefactive lesions, moldy areas. The size of the bottom of the bulb is of particular importance - its small size indicates the immaturity of the bulb.

The usual bulb size is 5-7 cm; bulbs up to 10 cm in size are rare. Used bulbs should be replaced annually with new ones; for this, children are used that arise at the base of the bulb. Children can be from 1-2 to 200 pieces, depending on growing conditions, biological characteristics and growing method.

How to germinate gladioli

It is customary to germinate gladioli before planting, but this is not necessary, just the germinated bulbs will give faster growth and flowering. When asked when to germinate gladioli, one can answer that to some extent this may depend on the climatic zone. In the middle lane, gladioli can be germinated from mid-March. The bulbs are laid out in a shaded but warm place. An abundance of bright light will lead to too vigorous growth of the sprout, which is not desirable.

A couple of days before planting, sprouted bulbs can be placed on a damp cloth - small roots will quickly appear on them. Before planting, the bulbs can be treated with a solution of karbofos.

How to plant bulbs correctly

  • The depth of planting of the bulbs depends on: their size, the larger the bulb, the deeper it can be planted, on the quality of the soil, on light soils - deeper, on loamy soils - shallower.
  • When planting tubers at greater depths, you can get a later flowering, a larger bulb with a small number of children.
  • The greatest danger to gladiolus bulbs is a cold, rainy summer - they can die due to bacterial and fungal infections.
