Geraniums may help deter Japanese Beetles

In 1929, it was discovered that a natural control for adult beetles is, believe it or not, geraniums. The beetles feed on the geranium leaves and flowers, which puts them into a narcotic state for 12-18 hours. They lay on their backs while enjoying their altered state, which makes them susceptible to predators and easy for gardeners to collect and crush. Some beetles ingest the irresistible geranium leaves so often that they die from it.

But don’t interplant geraniums around your roses, thinking that this will deter the pests. Because Japanese Beetles love geraniums so much, interplanting will create the opposite effect and attract so many beetles that your roses will become infested. Plant a patch of geraniums in a sunny place far away from the plants you want to protect – it’s believed that the sun has an intensifying effect on the narcotic substance in the geranium leaves. 


Japanese Beetles are one of the most reviled garden pests. They feed on over 300 plants and are very difficult to get rid of.

            今年活了一棵。把根上的土抖掉然后倒头放入纸袋或大纸箱内封口放在车库，一到两个月往里喷点水(我懒没做)，来年春天取出修剪一下种花盆里或地里就行了。我一没喷水，今年春天取出后又在外面地里放了几天才下的地，也是成活率低的原因。好像有视频教的。
            • 我去年把天竺葵拔出来倒放在纸壳箱里，死了两棵大花天，马蹄纹天竺葵四棵全都活了下来，这个办法可行。今年冬天准备再用新买的垂吊天竺葵试试。 -qingli(Qingli); 01:27 (#16305135@0)
