I've dug out patches of grass from my flower beds and found grubs there. Will they affect the flowers planted there or do I need to apply "grub stuff" there too?
What we call grubs can be the larvae of a variety of beetles. In flower beds, the grubs that are larve of the Japanese beetle are probably of the most concern.However, the larger roots of most flowers are not as vulnerable to damage as the tiny roots of turf grass. The problem occurs when the grubs turn into beetles and devour flowers.If you notice damage from beetles, the infestation is probably severe enough to warrant treatment. Use an insecticide made specifically for beetles. Follow package directions exactly, but you will probably need to reapply every 6 weeks as subsequent grubs in the soil develop into beetles.
