How to Get Rid of Aphids on Hibiscus Plant

aphids-on-the-flower.jpg (1003×664)

Aphids (Aphis gossypii) are a fairly common parasitic insect that likes to feed on plants belonging to the popular Hibiscus genus.

These insects are extremely small and as such barely visible to the naked eye. As a matter of fact, they tend to be typically 6/100-inch long or so and their coloring ranges across a spectrum going from yellowish green all the way to green black, which enables them to merge into the background. Their coloring in fact, is an ideal camouflage against many larger predators who would prey on these tiny insects.

As a general rule, many if not most of these otherwise pear shaped insects typically tend to feed directly from the rich and highly nutritious (from the aphid point of view, that is) juices present inside the leaves of the plant. Apart from that, they also simply love to feast on the succulent new growth that the plant puts out even as it grows older. As a matter of fact, many such aphids are fond of feeding in large clusters, and they tend to do so in numbers that are quite capable of causing large scale and extensive damage to many different types of plants. Such damage includes leaf curling and even distortion of the plant altogether. And if that is not bad enough then they can also carry plant viruses that cause highly infectious illnesses amongst your precious flora. This is why it is absolutely imperative that you get rid of the aphids from your Hibiscus plantation once and for all. Granted the miniscule parasites are very hard to eradicate indeed, but should you try hard enough and furthermore, be persistent enough there is no reason why your hibiscus plants cannot be free of the aphid scourge, at least before the end of the season.

There are some of the actions you can take so as to try and wipe out the resident aphid colony (or colonies as the case may be) from your Hibiscus patch or plantation.

  • Good old fashioned H2O

If you have a garden hose, then simply spray the hibiscus that has been infested with large and unwanted populations of aphids with a spray jet of water, from your hose so as to dislodge them completely from their respective perches. By and large, the aphids are widely considered to be the veritable ‘snails’ of the insect world due to their inherently slow movement. Even if they survive your drowning attempts, the odds are that they will be too slow and clumsy to make their painful way back to their original homes on your plants. In the process, they are far more likely to die of starvation than to continue to suck the lifeblood of your plants while simultaneously breeding away for all their worth. Once you have thoroughly washed them you should then get hold of a powerful magnifying glass to see if they are still around. For good measure periodically wash the plants at least once or twice a fortnight or so.  

  • The healing powers of insecticidal soap

You can either apply rosemary oil or any powerful insecticidal soap (or both) to the unfortunate hibiscus that may well be infested with these pests. In fact, there is no need to simply restrict yourself to mere Hibiscus alone since you can also do the needful on nearby plants as well (some types of aphids are not particularly picky about the kind of plants they tend to feed on). However, you should only apply such pesticides ‘after’ you are done spraying the plants, since the water can help thin out aphid populations considerably, in its own right.

When using the pesticide soap, make sure that you coat the whole plant well and thoroughly, while simultaneously making sure to cover both the over and the undersides of the leaves as well, right along with the inverted V or the crotches of the branches. However, such pesticides tend to lose their efficacy in high temperatures since aphids tend to hide from the sun. This is why you should wait to apply either or both the chemicals, as and when the weather conditions are suitable for the operation. By this it is meant that the overall outside temperature is well below 80 degrees Fahrenheit. For best results, you should repeat all such applications at least once every two weeks or so or at least till you are reasonably sure that the aphids are gone, for good.

  • Feed the plants some imidacloprid

As a finishing touch, you should treat the soil immediately around any severely infested hibiscus with a chemical known as imidacloprid, which should be mixed as per the instructions prominently displayed on the carton. Once the soil has been liberally coated with this chemical you should then commence to saturate the whole area with large amounts of fresh water so as to encourage the uptake of this important chemical by the plant. Once the work is done you should wait for at least a week or so for the chemical to work and for the aphids to die once they partake a meal from your favorite plant. This is because this chemical is extremely toxic to different types of inspects, especially hibiscus loving aphids and while it does not do any damage to the plant itself, nevertheless it turns it into poison for the aphids that live and thrive on it.
