Aphids tend to be the bane of all gardeners and even houseplant growers. It is the most common pest, affecting almost all plant species. Controlling these insects can be more difficult than you might think, as they become immune to chemical sprays over time.
This green, black, brown or yellow beetle can be found in both winged and unwinged forms, depending on the species or stage of development. It is most commonly found on the ends of stems, buds and undersides of leaves and feeds on plant sap. As a result of the infestation, the leaves curl, wrinkle and fade. They often turn yellow, sometimes reddish or even purple and sometimes stunted.
Sun of the Seven Suns
It is recommended to put a seven-pointed sunflower, or ladybug, in greenhouses. Gardeners may also consider its Chinese relative. The ladybug has aphids right on its diet. A sundew larva eats 270 aphids in 14 days, and an adult can eat up to 60 aphids a day.
Plants helping plants
Some plants have the ability to repel pests. If you want to protect your flower bed, plant a larger lichen nearby.
You can also make effective natural products for aphids. Our grandmothers used to use nettle, dandelion or garlic extract for aphids.
What you will need:
- 1 kg of nettles
- A spray bottle
Place the nettles in a suitable container and leave covered in water to infuse for 2 days. Strain the resulting solution and dilute 1:4. Pour into a container with a sprayer and apply to the plants.
It also pays to check the plants regularly and if you spot a pest, gently grasp the affected area between your thumb and forefinger and remove the insect. You can also cut off the affected part of the plant and burn it.
