Pesticides not always best when dealing with pests
The weather kept the warm-season flowers from flourishing, but then conditions changed rapidly. With the heat, the warm-season flowers are now growing well, but several other problems are plaguing my posies.
In a perfect world, there would be nothing to bother my prized blossoms. Insects would confine their voracious feeding to weeds that dare make an appearance, thereby saving me countless hours of weeding. Diseases would attack any pests that might want to eat my fragrant flowers.
Unfortunately, insects and diseases show no respect. They are happily munching away on my tender blossoms. I don't mind them snacking occasionally, but they seem to think I have set out a banquet for them, their friends and their relatives.
While there are many pesticides to control these pests, other options are often more effective and less expensive.
At the top of the pest list are the slugs and the snails. If young seedlings disappear or your plants develop large holes in the leaves, these mollusks are the likely culprit.
They are not easy to control. Start by going on patrol. After dark or early in the morning, go out and pick them up.
Although the temptation is to smash them into oblivion, keep in mind that they are not "he's" and "she's" but "its," so all have eggs that will eventually hatch — even after you crush the pests.
Throw them into a bucket of soapy water, tie them into a plastic bag and send them off with the trash.
Baits are effective but often misused. Most become ineffective once they get wet, so consider using traps or stations to extend the baits' effectiveness and prevent birds and pests from consuming the baits.
Another persistent and aggravating problem this year is the European earwig. I suspect the spring moisture increased their numbers, too. European earwigs are sneaking out at night and skeletonizing the leaves on my verbena, castor beans and several other flowers. Go out with a flashlight and see if they are striping the leaves off of your prize flowers, too.
Like the snails and slugs, they like to hide. They are not social insects, but they do cluster in large groups under rocks, boards or other moist, dark places. Finding and destroying these nesting areas will help reduce their numbers. They are particularly fond of marigolds, dahlias, zinnias and hollyhocks.
