Blackfly, Greenfly and Aphid control

Blackfly, Greenfly and Aphids love the garden and will be prolific in your garden now the weather has warmed up.  They are unsightly, leave a mess and will stunt, or kill off, your plants if left unchecked.  They are not fussy eaters - they will try most plants, but have a preference for broad beans, nastursiums and roses, where they suck the sap off the plants.

Biological control is always the first line of defence.  Try and plant flowers in the garden that will attract bees, ladybirds and hoverfly.  These insects will go some way to keeping the population of aphids down. However, they are not always seen in the garden early enough for total control.  In enclosed spaces, such as greenhouses, it is possible to purchase parasitic wasps which do a good job on aphids.

Companion planting will help to keep aphid numbers down, but will not stop them all.  The smell of onions and garlic planted near vunerable plants will deter most pests.  Likewise mint, coriander, dill and oregano are know to be repellents.  Planting tagetes and marigolds near tomatoes and roses works too and is especially successful in the greenhouse.

Nipping out the tips of broad beans will slow blackfly progress.  Planting nastursiums will attract blackfly and if you are happy to sacrifice the nastursium, then often the blackfly will stay on them, leaving other plants alone.  Squashing bugs between your fingers may be messy and time consuming, but is a cheap and natural method!

Chemical solutions are available.  Bug clear and Rose clear can be sprayed when infestations occur.  Beware that some chemicals are also harmful to bees, so make sure you read the packet instructions.

Vigilance and early action is the key to maintaining a healthy garden.  Enjoy!
