Summer is upon us. Not only are temperatures rising, but so is the likelihood of a few garden pests. The three that seem to be getting the most attention right now, turning up in gardens from Laguna Beach and Newport Beach to Huntington Beach and Costa Mesa, are rose slugs, giant whiteflies and citrus leafminer.
If you have one or all three of these pests, don't panic. Learn a bit about them and then decide on the best strategy — which might be to do nothing at all. Where possible I always suggest organic or natural solutions, which are not only more environmentally appropriate, but build healthier gardens over time.
Rose slugs get busy every year once the weather warms up, usually about May or so. By July the damage is very noticeable on rose leaves. The leaves become riddled with hundreds of holes and irregular scratches. Heavy infestations can skeletonize the entire leaf, leaving just the veins.
