Propagation of Phlox alaskensis Jordal
Phlox alaskensis Jordal is a beautiful plant with soft lavender-blue flowers that bloom in the summer. This lovely plant propagates by several methods such as seeds, stem cuttings, and division.
Propagation by Seeds
Phlox alaskensis Jordal is easily propagated by seeds, which are usually sown in early spring, in pots filled with a mixture of peat and sand. The seeds should be lightly covered with soil and kept moist. The pot should be placed in a warm and bright area, and germination should occur within two to three weeks. Once the seedlings have grown large enough, usually when they have their first leaves, they can be transplanted into small pots filled with a good quality potting mixture.
Propagation by Stem Cuttings
Phlox alaskensis Jordal can also be propagated by stem cuttings taken in summer from the non-flowering shoots. The cuttings should be about 3-4 inches long, and the lower leaves should be removed. The cuttings should be dipped in rooting hormone powder and planted in a pot filled with a mixture of sand and peat. The pot should be kept moist and placed in a warm and bright place. Within four to six weeks, the cuttings should begin to root, and they can be transplanted into small pots filled with a good quality potting mixture.
Propagation by Division
Phlox alaskensis Jordal can also be propagated by division. This method is best done in spring or fall when the plant is not in flower. The plant should be lifted from the ground carefully, and the roots should be gently separated. Each separate root clump should have several shoots and healthy roots. The clumps can then be replanted in a new location or in pots filled with a good quality potting mixture. The new plants should be watered thoroughly and kept moist until they are established.
