Aphids are drawn to tasty, tender young shoots, so one of the keys to keeping their numbers in check is to avoid over-fertilizing your plants.
Plants are more defenseless during hot, dry conditions, as they’re not able to produce the chemicals they need to fend off pests.
Of all the good bugs you should attract to your garden, green lacewings and lady beetles are two of the most powerful and efficient predators to keep around.
Trap cropping is another form of companion planting as it’s most effective when planted around, or next to, the plants you want to protect.
After all, everyone’s got a garden hose; just aim it directly at the affected leaves and stems to spray the aphids off.
