For Tom Kasper, there are two things the gardens could use this summer. One is more rain. The other is fewer leaf hoppers.
The very small insect known as the leaf hopper can be detrimental to our gardens. The critters have a penchant for causing more damage to vegetation than even deer or rabbits. And perhaps most unfortunately, the leaf hoppers might be here to stay. Milder winters and warmer summers over the last couple decades have offered an ideal breeding ground for the insects.
However, there are ways to combat the invasion. Natural pesticide options include sprays with neem oil or pyrethrin. These sprays will require diligence and multiple applications. Introducing lady bugs or lacewings (two known predators of the leaf hopper) into your garden is another natural option. Additionally, there are certain plants that the leaf hoppers just don't like. Petunias and geraniums omit a smell that - for whatever reason - will repel these pests.
