Selecting Stock Plants – September is a good time to begin making cuttings for starting next year’s plants. Lantana cuttings should be made from seasoned wood before any lush growth occurs after the fall rains. If the cutting wood is soft, the cuttings will rot or blast instead of developing roots. The colorful Jacob’s coat (Alternanthera) can be kept as cuttings over winter as can other types of herbaceous plants such as hibiscus, geraniums, coleus, ice plant, sultana and wandering Jew. By September, these plants are conditioned properly for taking of cuttings.
Roses – The cool nights of September will stimulate new growth for a lush crop of bloom during early October. This means the last application of fertilizer should be made this month. Light liquid feedings will be very beneficial, or you may use your own pet brand of commercial fertilizer or rose food. Cottonseed meal is a wonderful food and should be used at the rate of one-half teacupful per plant and worked in lightly around each plant. Heavy watering should follow so that the rose plant may absorb the food. Throughout our section, the quality of fall roses often surpasses that of spring blooms, even though they are usually fewer in number. In watering, keep the water off the foliage and do not water after mid-afternoon in order that the plants can go into the night with surfaces dry. The usual disease and insect pests are prevalent during this fall season, so be on constant guard to protect these plants.
