We grow bulbous irises: planting and care features

A friend shared a few iris bulbs. In my country house, only ordinary irises (those with rhizomes) grow, so there was a small problem of what to do with the bulbs. I would very much like to learn more about planting and caring for bulbous irises. And another question is of interest: when and where it is better to plant them and can they winter in a flower bed?

bulbous irises The cultivation of bulbous irises is somewhat different from simple rhizome species, which are much more common in flower beds. The peculiarities of the root system also dictate special rules for planting and leaving the bulbous irises. First of all, this is due to the fact that delicate bulbs require careful selection of the planting site. In addition, most varieties are extremely thermophilic, and are absolutely unable to survive outdoors in our winters. However, let’s talk about everything in order..

When to plant?

The time for planting bulbs in open ground depends on the type of irises, for example:

  • compact and frost-resistant iridodictiums can be planted in the fall, but no later than September, so that the plants have time to take root and get stronger;
  • less resistant species of Juno irises will also survive the autumn planting, but subject to additional shelter in warmer regions;
  • sissies xyphyums (Dutch irises) are best planted in the spring, because even at a temperature of 10 degrees below zero, the bulbs die.

When planting frost-resistant early flowering varieties of irises in the spring, it should be borne in mind that there will be no flowering in the year of planting, but only for the next season.

Where to plant?irises bloom

As you know, all bulbous crops (and irises are no exception) do not tolerate high humidity. Areas that suffer from flooding in spring are categorically unsuitable for these plants. Regarding the soil, the best option would be fertilized sandy soil, light enough and fertile.

To grow bulbous irises, you need to select the lightest flower bed – only in good light conditions will they bloom well.

Preparing and planting bulbsonion processing

For the purchase of planting material, it is best to contact a specialized store – there are less chances to buy diseased plants. To protect flowers from diseases, especially putrefactive infections and fungi, before planting, they must be kept for 30 minutes in a solution of Fundazol or at least potassium permanganate, and then let them dry completely.

A healthy iris bulb is firm to the touch, covered with a shiny golden skin and free from strange spots and marks of damage.

planting irisesThe depth of the hole for the bulb should be no more than three diameters, and the distance between them should not be less than 10 cm.It is not necessary to water immediately, the available moisture in the soil will be enough for the irises, but the next day you need to moisten the soil well in the hole.

Care featuresstorage of irises

It is simple to care for bulbous irises: in the spring they need to be watered regularly, but by summer the frequency of watering should be reduced, because at this time most varieties are already resting. With the arrival of autumn, dig up the xyphyum bulbs, let them dry and put them in a cardboard box for winter storage. Most flower growers dig up all varieties of irises in the summer, and in the fall they return them back to the garden (except for Dutch ones – they are stored until spring). This is especially true if it rains often, because then the irises can rot..
