In this weekend’s Root Awakening column, answers to three gardening questions were given. The first question dealt with the spraying of pesticides by our neighbours. Note that pesticides vary in terms of their toxicity and all should be treated as harmful. One should advise his neighbor to inform him whenever a pesticide application will be performed so that the necessary precautions can take place. It would also be useful to know the type of chemical that is being applied so that you can do some homework to know what protective measures to take. Some pesticides are very toxic to fish and aquatic life so make sure pesticide fumes do not reach them.
The next question was about a local medicinal herb, which is botanically known as Gynura procumbens. It is a plant that is a member of the daisy family, Asteraceae, which is eaten as a leafy vegetable in some parts of the world. To date, its cancer-curing properties have not been systemically assessed and proven. This plant is also believed to be able to reduce high blood pressure and lower serum glucose levels, amongst others. Further studies need to be performed to confirm such effects. It is best to consult a certified practitioner before consuming such herbs.
The last question queried about the identity of a houseplant with purple foliage. Botanically known as Oxalis regnellii ‘Atropurpurea’, this particular houseplant is known via a range of common names that include Purple Oxalis, Wood Sorrel and False Shamrock. It is native in Argentina, Bolivia, and Paraguay and can be propagated via division of the crown. Grow it in a protected, semi-shaded location away from winds. It prefers to grow in a well-drained soil mix such as one concocted for container gardening. Keep soil moist at all times and not soggy. Fertilize weekly with a balanced fertilizer.
