The third instalment of the Root Awakening column was published today.
The first question dealt with an ant problem encountered during the growing of the fragrant pandan plant. One can remove ants from his/her pandan plants by sprinkling some ant powder (active ingredient – permethrin) that is available in most plant nurseries. Do not allow pets or young children from having close contact with plants after application. Wash thoroughly leaves after harvesting before use.
The enquirer also mentioned that young leaves have a tendency to die or turn brown at bent parts of a plant. One has to avoid injuring the leaves or young growing tips of plants unnecessarily as this can irreversibly damage the plant. Harvest damaged leaves by making a clean cut by using a sharp pair of scissors.
The next question was about problems faced in a newly purchased rose. Rose plants bought locally may have been newly imported from a cooler growing area. It is not unusual for it to show signs of stress which include the yellowing and shedding of leaves. It is recommended to cut off any remaining flowers and buds to avoid stressing the plant further and the pruning involved is likely to help the plant recuperate faster. After pruning, locate the rose plant in a semi-shaded location for new growth to appear. Avoid relocating to an area with full sun yet as the heat may affect the plant adversely. Keep the roots moist at all times and feed with a water-soluble fertiliser such as Phostrogen to promote new growth. Keep common rose pests like red spider mites and thrips at bay by spraying with Confidor.
The last question was about the growing of the jasmine plant and use of manure to feed them. Jasmine is a flowering shrub that can be grown in outdoor areas with semi-shade to full sun. In general, jasmine requires good light to flower and prefers to be grown in a well-draining and moist potting mix. Keep the roots moist at all times. Feed with a water-soluble fertiliser such as Phostrogen to promote vigorous growth and production of flowers.
Manure, in general, is made up of processed animal waste and is rich in nitrogen, which only promote foliage growth. You may need to supplement your plants with another fertiliser such as a balanced fertiliser (in the form of pellets or water-soluble salt form) to meet your plants’ nutrient needs.
