Whilst there are many beneficial insects in your yard or garden, there are insects that can cause damage to your plants as well. Apart from sucking the nutrients from plants, these pests spread virus and diseases that can cause major damage.
Landscape expert Oakleigh Manor shares a few tips on controlling common plant pests:
These little soft-bodied insects come in different colours. Aphids are characterised by their long antennae or a tubes projecting rearward from the abdomen. They feed on the sap of the plant and decrease its rate growth. They also transmit virus to the plant, which can make the leaves distorted.
You can control aphids by washing your plant with a natural-based pesticide or garlic repellent sprays. For extreme infestation, use insecticidal soap or horticultural oil. Keep your plants always healthy and use dormant oil to control overwintering eggs in trees.
These small insects are like fleas when disturbed. Some species like brussel sprouts and brassic as while others prefer wallflowers and alyssum. Adult species eat small round holes in the leaves while larvae feed on plant roots.
Repel flea beetles by spraying plants with garlic spray or kaolin clay. Frequent watering also helps, as beetles do not like wet leaves. You can also surround their favourite plant with herbs like and parsley, which attract good insects. Consult garden designers to know other flowers and plants that can attract beneficial insects.
These are sap feeding pests that weaken plants. They leave infected leaves yellow or discoloured. Extremely infected plants, meanwhile, lose their vigour. A colony of scale insects on a leaf or a stem will seem like the scales on a fish. They have a thick skin makes them resistant to contact with insecticides.
Stop these insects from damaging your plants by pruning out infected parts. You can scrub the scales gently using a soft brush and soapy water. Spraying with a neem oil or a broad spectrum insecticide helps as well.
Keep the beauty and health of your plant by getting rid of these insects. You can contact garden designers as well to help you create landscaping plan that is less prone to insect infestation.
