Why are gladiolus bulbs sick

For several years now, more than 50% of varietal gladioli have been dying in our garden. In autumn, we carefully select only healthy bulbs, burn all diseased bulbs, and store a small part of diseased bulbs separately and plant them in an isolated area. After two or three years, we change the site, constantly in the fall and spring we pickle the bulbs with a strong solution of potassium permanganate. Yet more gladioli die each year. They bloom, give a good ear, and then the lower leaves of the plants begin to turn yellow, and when we dig up the bulbs, many are sick: with brown scales and yellow roots. Such bulbs do not produce babies. What's the matter? It would seem that we follow all the rules of agricultural technology.

Your gladioli are affected by a whole range of bacteria and fungi. Their development is favored by cool, damp weather.

It is necessary to grow gladioli in a sunny area, It is recommended to plant garlic, marigolds and marigolds next to gladioli for prevention, Before planting corms, they should be etched with potassium permanganate, immersing them for two hours in a solution of the following concentration: 3 grams per 10 liters of water.

In autumn, it is necessary to burn even weakly affected bulbs, Only if it is a very valuable variety and a very small part of the bulb is affected, cut off the affected area with a sharp knife and sprinkle the cut with crushed coal. The wound is always the gateway to infection.

It is important to dry the corms removed from the field quickly (within a week) at a temperature of 30-35 ° and good ventilation. In the same place, gladioli can be planted not earlier than after 4-5 years, but better and later.

correct agricultural technology is of great importance. It is necessary to give more air access to the root system of plants: loosen, loosen and loosen the ground so that the water does not stagnate in it.

You can not fertilize the site with unburned manure, this contributes to fungal diseases.

Mineral fertilizers are applied to the soil before planting at the rate of 10 g of ammonium nitrate, 15 g of superphosphate and 10 g of potassium salt per square meter.

During the summer, 2-3 fertilizing with mineral fertilizers is carried out. The first feeding is given at the stage of the developed 3rd leaf, the second - at the stage of the 5-6th leaf, the third - before flowering.

Flower feeding always carried out after good watering with clean water or after rain. When cutting flowers, it is necessary to leave 3-4 leaves on the plant for better development of corms and growth of the baby.

Gladioli age quickly. In the third year, the bulbs become flat. They need to be updated and replaced from the baby.
