Ixia is propagated with the help of bulbs, which form plants that have reached 3 to 4 years. The children are carefully cut with a sharp clean knife, the places of the cuts are sprinkled with crushed coal or treated with brilliant green.

If you want to get planting material in a short time, take the corm of an adult plant and cut it into pieces so that each has a root bud and a part of the rhizome. Do not forget to process the places of cuts, this will help to avoid rotting of the bulbs.

The seed method of propagating ixia is practiced only by breeders when it is necessary to obtain a new variety. This process is quite time-consuming, requires a lot of time, knowledge and experience.

Site preparation

The bulbs are planted in the garden during the spring and autumn months. Spring planting for regions with a temperate climate is carried out in April, in middle latitudes – in the last days of May or early June. It should be borne in mind that the bulbs freeze at air temperatures below 2 degrees.

For this culture, it is important to choose the right site, its well-being and flowering will depend on this. A good option for a light-loving flower is well-lit places in the garden, which are located far from trees that create shade.

The soil should be saturated with nutrients, have a neutral acidity. It is advisable to enrich the substrate with humus before planting. It is not recommended to plant a plant in places where there is a close location of groundwater.

The site chosen for ixia is preliminarily dug up, leveled, stones are removed, and earthen clods are broken. If the soil is heavy, add sand.

Landing Rules

Planting material is carefully inspected before planting. For planting in open ground, only healthy ixia bulbs are chosen without signs of damage and mold, otherwise further care will be useless. Bulbs should be firm, dense, without dents.

On the prepared site, small holes are made about 8 cm deep. The distance between plants should be at least 20 cm. Watering after planting is not necessary.

The surface of the soil should be leveled and mulched. Flowering will come after 1 – 2 years. It is noticed that large bulbs germinate and bloom faster compared to those that are medium and small in size.

Agricultural technology

A South African plant will successfully develop and bloom actively only if suitable conditions are created for it, as close as possible to natural ones. This culture needs an abundance of sunlight, air temperature in the range of 23 – 30 degrees. High humidity is also important.

The following are care tips for growing Ixia outdoors, which will allow you to get a profusely flowering healthy plant and prevent the appearance of pests and diseases:

  • Watering. The first watering should be carried out after 2 – 3 weeks after planting the bulbs on the site. Irrigate young plants should be moderate, waiting for the top layer of the earth to dry out. More intensive watering is needed for plants during the development of buds and during the flowering period. Water should be settled, not cold. It is advisable from time to time to add preparations that promote active flowering to the water for irrigation. To create high humidity, ixia is sprayed daily from a spray bottle throughout the entire flowering period. After carrying out water procedures and rains, the soil near the bushes is loosened to saturate the roots with oxygen and eliminate weeds.
  • Topdressing. Fertilizer is applied from June until the end of flowering. Use mineral compositions for corms and organics. After the plant has faded, care for it is stopped.
  • Wintering. After flowering, the bulbs are kept in the ground for another 4 weeks. During this time, they manage to accumulate a supply of nutrients. Dig bulbs in the second half of July. After digging, they are cleaned in a ventilated place to dry. Store in wooden boxes in a room with low humidity and a temperature of 7 – 15 degrees.
