Application in landscape design
Recently, decorative varieties of Iberis have enjoyed deserved popularity among landscape designers. Low-growing varieties of annual crops look original:
- in the foreground of flower beds, flower beds;
- on alpine slides and rockeries;
- on borders and lawns.
Iberis is a universal crop that succinctly combines with spring bulbs (tulips), marigolds, night violet, saxifrage, alyssum, petunia, and phlox.
Growing annual Iberis from seeds
Iberis is not propagated vegetatively due to the taproot structure of the root system, which complicates the process of dividing adult bushes.
Plants are grown from seeds using two main methods:
- direct sowing of seeds into the ground;
- sowing for seedlings.
Direct sowing into the ground
Direct sowing of seeds of the annual Iberis flower in open ground is carried out in April. To obtain a flowering flower bed in May and August, they are embedded in the soil with a 2-3 week break.
You can sow seeds in the ground at the end of autumn when stable cold weather sets in (to prevent premature germination).
Agricultural technology for sowing seeds in open ground:
- the bed is dug up and leveled;
- form grooves at a distance of up to 5 cm from each other;
- seeds are sown in furrows, lightly sprinkled with earth;
- crops are moistened.
If there is a possibility of a drop in temperature at night, the crops are covered with film. 2 weeks after emergence, the bushes are thinned out at a distance of 15 cm from each other.
Growing seedlings
Seeds of annual Iberis are sown for seedlings in February-March. Equal parts of peat, sawdust, and sand are mixed as a soil mixture. The soil and containers are disinfected.
Algorithm for obtaining seedlings:
- grooves up to 1 mm deep are formed in containers;
- the seeds are placed in grooves without a depression, sprinkled with river sand;
- The crops are moistened with a spray bottle and covered with film.
The box with seedlings is placed in a warm place with diffused natural light. The crops are moistened with a spray bottle as the soil dries. Iberis seedlings do not dive. It is best to plant seedlings in disposable cups or peat tablets.
Planting and caring for annual Iberis
Annual varieties of Iberis do not require complex care. It is enough to follow the agricultural planting techniques, ensure proper watering, fertilizing and promptly inspect the bushes for diseases and pests.
Recommended timing
Iberis seedlings are moved into open ground once the threat of spring frosts has passed. Experienced gardeners recommend replanting it in May.
Site preparation
Iberis annual prefers soil without close groundwater, not prone to stagnation of water. It can be:
- well-lit areas;
- loamy, sandy or rocky soil;
- soil fertilized with organic fertilizers in the fall (manure).
Landing algorithm
Since Iberis seedlings are tender, thin sprouts with a rather vulnerable root system, they are moved to open ground by transshipment.
Landing rules:
- planting holes are formed in the garden bed at a distance of 12-15 cm from each other;
- the seedlings are moved into the planting holes along with a lump of earth;
- the bushes are carefully pressed to the ground, the soil is compacted;
- seedlings are carefully watered at the root.
Watering and fertilizing
Iberis is an unpretentious plant that requires minimal care:
- moderate watering no more than once a week;
- loosening and removal of weeds;
- fertilizing 2 times during the growing season.
Trimming
Overgrown bushes are pruned to give the plant a well-groomed, neat appearance. In addition, faded inflorescences should be removed in a timely manner.
Pests and diseases
One-year-old Iberis is endowed with fairly stable immunity to pests and fungal pathogens. In some cases, the annual Iberis flower is exposed to pathogens:
- Cruciferous clubroot attacks the roots.
- Black scab, or rhizoctonia, appears as gray, brown spots on foliage and inflorescences.
Among the pests that attack Iberis plantings are the following:
- The appearance of a mealybug is accompanied by the formation of a white coating on the shoots.
- Cabbage aphids suck juices from young shoots. As a result of the influence of parasites, leaves and flowers turn yellow and fall off.
Conclusion
Planting and caring for annual Iberis is accessible even to novice gardeners. This unpretentious plant develops quickly even with minimal care and blooms profusely and attractively all summer long. You can sow the seeds of Iberis annua in the ground at intervals of 2-3 weeks and twice during the summer season enjoy the magnificent and fragrant flowering of delightful umbrella-shaped inflorescences in white, pink, purple, lilac tones.
