Growing annual Iberis from seeds
Iberis is not propagated vegetatively due to the core structure of the root system, which complicates the process of dividing adult bushes.
Plants are grown from seeds, two main methods are used:
- direct sowing of seeds into the ground;
- sowing for seedlings.
Direct sowing in the ground
Direct sowing of the seeds of the annual Iberis flower in open ground is carried out in April. To obtain blooming flower beds in May and August, they are embedded in the soil with a 2-3-week break.
You can sow seeds in the ground in late autumn when stable cold weather is established (to prevent premature germination).
Agricultural technology for sowing seeds in open ground:
- the garden bed is dug up, leveled;
- form grooves at a distance of up to 5 cm from each other;
- seeds are sown in grooves, lightly sprinkled with earth;
- crops are moistened.
If the temperature drops at night, the crops are covered with foil. 2 weeks after the emergence of shoots, the bushes are thinned out at a distance of 15 cm from each other.
Growing seedlings
Annual Iberis seeds are sown for seedlings in February-March. As a soil mixture, mix equal parts of peat, sawdust, sand. The soil and containers are disinfected.
Algorithm for obtaining seedlings:
- grooves up to 1 mm deep are formed in containers;
- seeds are placed in grooves without deepening, sprinkled with river sand;
- the crops are moistened with a spray bottle and covered with foil.
The seedling box is placed in a warm place with diffused natural light. Crops are moistened with a spray bottle as the soil dries out. Iberis seedlings do not dive. It is best to cover the seedlings in disposable cups or peat tablets.
Planting and caring for annual Iberis
Annual varieties of Iberis do not need complicated care.It is enough to observe the agricultural technique of planting, ensure proper watering, feeding and timely inspect the bushes for the detection of diseases and pests.

- soil fertilized with organic fertilizers in the fall (manure).
Landing algorithm
Since the seedlings of Iberis are tender, thin shoots with a rather vulnerable root system, they are moved to open ground by the transfer method.
Landing rules:
- planting pits are formed on the garden bed at a distance of 12-15 cm from each other;
- the seedlings are moved to the planting holes along with a lump of earth;
- the bushes are carefully pressed to the ground, the soil is tamped;
- seedlings are carefully watered at the root.
Watering and feeding
Iberis is an unpretentious plant that requires minimal maintenance:
- moderate watering no more than 1 time per week;
- loosening and removal of weeds;

Pruning
Pruning overgrown bushes is done to give the plant a well-groomed, neat appearance. In addition, faded inflorescences should be removed in time.
