Umbrella Iberis can be propagated by seed or cuttings. The first option is more difficult. The material is immediately sown in open ground or seedlings are first grown. The seeds can be purchased at the store or prepared by yourself. To do this, you need to collect the pods and dry them so that they open. The resulting seeds are stored in a dry and dark place. They are planted the next year, the material remains viable for up to 3 years.
It is not difficult to propagate a plant by cuttings. The algorithm is as follows:
- After flowering, cut the cuttings, each no more than 5 cm long.
- Process the material with phytohormones.
- Root the cuttings at a minimum interval of 15 cm. This can be done outdoors or in a greenhouse.
Umbrella Iberis can be planted with seedlings. In this case, flowering begins earlier.
Sowing seeds for seedlings is carried out in March. Due to the sensitivity to transplanting, separate containers must be taken immediately to eliminate the need for a pick. Algorithm for growing seedlings:
- Prepare the soil mixture. For the prevention of diseases, it should be treated in one of the ways - a solution of potassium permanganate, calcining, freezing, heating with steam.
- Fill the prepared containers with soil, moisten it.
- Sow seeds, deepening by 0.1-0.2 mm. You can simply spread them over the surface and sprinkle with river sand.
- Cover the plantings with foil or glass, place them in a warm place. The optimum temperature is 15-18 ° C.
Seedlings are easy to care for. It is important to provide diffused light, regular ventilation. After the emergence of seedlings, the shelter must be removed. Hardening begins 2 weeks before planting in open ground.
Planting and care in the open field
Umbrella Iberis is grown outdoors. The timing of planting, the right place and properly organized care are important.
When growing Umbelliferae from seeds, it should be planted no earlier than mid-April. The exact timing depends on the climatic conditions. It is optimal when the daytime temperature is set at 16-18 ° C. You can prolong flowering by planting seeds at different times. An interval of 2-3 weeks is recommended.
The plant can be planted with seeds before winter. They do it in September. At the same time, the germination rate is less, but flowering begins earlier.
If you grow Iberis umbrella seedlings, then the first planting in the ground is carried out in May
Site selection and preparation
Umbrella Iberis does not like transplants, therefore it is important to immediately choose the right place for it. It must meet the following requirements:
- intense lighting;
- sandy or loamy soil;
- permeable soil;
- the reaction of the earth is neutral or slightly acidic;
- heavy soil and moisture stagnation are excluded.
Planting an umbrella Iberis is easy according to the following algorithm:
- Prepare the selected area - dig up, remove all weeds, loosen.
- Make grooves or holes.
- Sow seeds, deepening by 0.5-0.7 cm.Leave 15-20 cm between adjacent plants.
- Moisten the soil.
Seedlings appear in about 1.5-2 weeks. The plantings will need to be thinned out immediately.
If Iberis is planted in open ground with seedlings, then this should be done when its height is about 7 cm. Plants must be removed from containers carefully together with an earthen clod.
Watering and feeding schedule
Iberis umbrella is unpretentious. It should be specially watered only on hot days and prolonged drought. The rest of the time, the plant has enough moisture from the lower layers of the earth. For greater decorativeness, you can water it regularly as the soil dries.

For the umbrella Iberis, the permeability of the soil is important, therefore it must be systematically loosened. This should be done after watering or heavy rainfall, while removing weeds.
To maintain the decorative effect of the umbrella Iberis, it is recommended to regularly remove dead inflorescences. When the plant has faded, it should be cut by at least a third. If self-seeding is not planned, the pods must be removed in a timely manner.
Umbrella Iberis is cultivated as an annual, therefore it is not necessary to prepare it for winter. Pruning of inflorescences and the plant itself is carried out for aesthetics.
Before winter, the Iberis must be dug up and burned. This measure serves as the prevention of diseases and pests. The freed area must be dug up, removing weeds, roots and debris.

Umbrella Iberis belongs to the Cruciferous family, therefore it is susceptible to diseases and pests characteristic of its representatives. One of the problems is downy mildew (downy mildew), which is expressed by a whitish bloom on the leaves. It is necessary to fight it with fungicides such as Gamair, Fitosporin-M, Alirina-B. For prevention, autumn digging of the soil and burning of plant residues are important.
High humidity is a risk factor for the development of peronosporosis.
The fungal disease of Iberis is keela. It manifests itself as growths and swellings on the roots. The affected plants must be removed, and the rest must be treated with Fundazol or colloidal sulfur. For the prevention of disease, ash or fluff lime must be added to the ground during autumn digging.
Roots affected by the keel poorly absorb moisture and the elements necessary for the plant
One of the enemies of the umbrella Iberis is the cabbage (cruciferous) flea. Its larvae and adults feed on leaves. You can get rid of the pest by dusting the plants with wood ash with tobacco dust or fluffy lime. Infusions and decoctions of dandelion, green wormwood, ash with laundry soap are also effective.
Cabbage flea can destroy young plantings in 1-2 days
Another enemy of the umbrella Iberis is the mealybug. These insects are also called felt or false pillows. You can fight the pest with chemicals: Kemifos, Fufanon, Tagor, Novaktion.
Mealybugs can be dealt with using folk methods. A solution of laundry soap, horsetail decoction is effective.
Mealybug feeds on plant sap, inhibits their development and immunity
Growing umbrella Iberis from seeds is also possible for inexperienced gardeners. The plant does not require special care, pleases with a long flowering even without additional fertilizing. All varieties of this type can be planted in open ground immediately with seeds.
