Propagation of rye from seeds

Q:Is it possible to multiply the thymus from seeds?

O:Western Thuja occidentalis (pure species) can be propagated by sowing. The cones are harvested in September and October, when the scales begin to part. The seeds fall out easily when drying the cones. They are stored dry and stratified at 4ºC for 4-6 weeks before sowing.You can also plant them without any preparation. The seeds are sown into the ground in April or May, previously dressing the seeds with a special dressing. After sowing, roll them up and cover with a thin layer of sand.

Of the cultivars of thuja, the 'Columna' cultivar repeats the maternal characteristics in a high percentage. The remaining varieties are quite easy to propagate vegetatively by cuttings. Planting begins in August and can last until December. Cut the cuttings and treat them with rooting.We put them in a special substrate for seedlings.
