St. John's wort is a unique medicinal plant, known as the "remedy for 99 diseases."
Perennial herbaceous plant up to 80 cm high. The stem is ribbed, smooth, branched in the upper part.
Leaves 1-3 cm long, entire, sessile, with numerous glands.
The flowers are large, golden yellow, collected in a wide paniculate inflorescence. Blooms in July-August.
The top third of the flowering plant is used as a spice.
St. John's wort is added to tinctures and soft drinks, as well as to tea.
Seeds are sown in early spring in open ground to a depth of 1-2 cm or in autumn on seedling beds. Seedlings are thinned out according to the scheme of 20x45 cm.
If the seeds are sown in February-March for seedlings, then preliminary stratification will be required:
sow seeds to a depth of no more than 0.5 cm, moisten with a spray bottle, cover with glass and place in a refrigerator (temperature +5 + 7 ° C).
Crops are kept under such conditions for 10-15 days, then transferred to room conditions (it is necessary to monitor the humidity of crops and ventilation).
At a temperature of + 18 + 20 ° C, shoots appear on the 10-14th day. If there is no germination, repeat the "cold-heat" method in the same sequence!
Seedlings dive into boxes in the phase of 2-3 true leaves. Seedlings are planted in the open ground after 4-6 weeks.
Prefers sunny places or light partial shade with loose, non-acidic soil. In one place it can grow 5-7 years.
