Cultivation of Aster Sibiricus L.
Aster Sibiricus L. or Siberian Aster is a hardy perennial plant that thrives in USDA zones 3 to 8. It prefers full sun exposure and thrives in fertile, well-drained soil. The best practice in planting Siberian Asters is to do it in spring after the last frost. Start by preparing the plant bed by removing weeds and adding compost or aged manure. Plant the asters about 18 to 24 inches apart and make sure to water them well after planting.
Watering Needs for Aster Sibiricus L.
Although it is drought-resistant, Siberian Aster requires consistent moisture to thrive. Keep the soil evenly moist but not waterlogged. Overwatering can lead to root rot. A good rule of thumb is to water deeply once a week, especially during the hot months.
Fertilization of Aster Sibiricus L.
Aster Sibiricus L. responds well to feeding, and it is best to do so during the growing season. You can use a balanced fertilizer, such as a 10-10-10 or 5-10-5 NPK, every four to six weeks throughout the growing season. Alternatively, you can use organic fertilizers such as compost tea, fish emulsion, or bone meal.
Pruning Aster Sibiricus L.
Pruning Siberian Asters is necessary to keep them from becoming overgrown and spindly. The best time to prune is in the late spring when the new growth appears. You can pinch back the top of the stems or cut them back by one-third to one-half to encourage bushier growth and more flowers. Deadheading spent flowers will promote the growth of new blooms and extend the flowering season.
Propagation Methods for Aster sibiricus L.
Aster sibiricus L., also known as Siberian aster, is a herbaceous plant that belongs to the Asteraceae family. This plant is native to Asia, particularly Russia, China, and Korea. Siberian aster features lovely lavender-blue petals that surround a yellow center. Siberian aster is often propagated through seed or division.
Seed Propagation
Siberian aster can be propagated through seeds, which can be collected from the plant itself. Harvest the seeds in the fall, after the plant has bloomed. Collect the seeds from the dry flower heads by shaking them, and set them aside in paper bags until spring. To start the seeds indoors, use trays or pots filled with potting soil. Sow the seeds by gently pressing them into the soil, and lightly cover with more soil. Afterwards, water the soil well to keep the seeds moist. The seeds will germinate within two to three weeks. Once the seeds have germinated, separate them and replant them in individual pots.
Division Propagation
Siberian aster can also be propagated through division. This propagation method is best done in the spring or fall. Select a mature Siberian aster plant and carefully dig around it. Divide the plant into smaller clumps by gently pulling the root ball apart. Make sure each division has leaves and roots, and replant them immediately in well-drained soil. The new divisions should be planted at the same depth as before and spaced far enough apart to allow for growth.
Propagation of Siberian aster is a simple process that can enhance the beauty of any garden. Whether you choose seeds or division, the results will be a magnificent display of beautiful flowers.
