Leaf-footed bugs appear on roses, tomatoes and other juicy plants

“Good guys or bad guys?” That’s the question that accompanied this photo of mystery insects that suddenly appeared on a rose bush in a Sacramento garden.
Definitely bad guys – and they’re beginning to pop up all over town, especially on tomatoes, soft fruit and roses. The reason? They love triple-digit heat.
Those are nymphs (babies) of the leaf-footed bug, a relative of stink bugs. They'll make holes through your roses (and lots of other things). They’re very bad on tomatoes and can be a pest on apricots and peaches. They also like pomegranates, almonds, pistachios, citrus and watermelons.
Most of their damage is cosmetic, but in big numbers they can be a real nuisance. They puncture the fruit’s skin and suck out its juices.
The good news: They can't fly and they're slow. When young, they stick together. They release a pheromone that keeps the developing bugs in a little pack. (The better to attack your plants.)

Like many stink bugs, they're resistant to any pesticides (unless it’s a direct hit). Because the young nymphs are wingless, their instinct is to jump down from wherever they’re dining and scramble for cover.
What to do? Under the plant, put a bucket or dishpan of water with a teaspoon of dish soap (to break the surface tension). Then, gently shake the bush, vine, branch or cane and knock the bugs into the water. (Often, they will just jump when they see your shadow.) They can't swim and they drown.
You also can blast the hell out of them with a hose (you’re watering the plants at the same time). Or you can just squish them, but wear gloves; they'll stain your hands (and they stink).

Garden checklist for week of Aug. 16
During this break in the heat, feed your garden. Make sure to water before and after applying fertilizer.
* In the garden, direct seed beets, carrots, leaf lettuce and turnips.
* Plant potatoes.
* Harvest tomatoes, beans, squash, pepper and eggplants to prompt plants to keep producing. Give your plants a deep watering twice a week, more if planted in containers. Also, give them a boost with phosphate-rich fertilizer to help fruiting.
* Watch out for caterpillars and hornworms in the vegetable garden. They can strip a plant bare in one day. Pick them off plants by hand in early morning or late afternoon.
* Feed citrus trees their last round of fertilizer for the year. This will give a boost to the fruit that’s still small.
* Mulch can be your garden’s best friend – it conserves moisture while blocking out weeds. But don't let mulch mound around stalks, stems or trunks. That can promote rot.
* Camellia leaves looking a little yellow? Give them some chelated iron. That goes for azaleas and gardenias, too.
* Pick up after your fruit trees. Clean up debris and dropped fruit; this cuts down on insects and prevents the spread of brown rot. Then feed fruit trees with slow-release fertilizer for better production for next year.
* To prolong bloom into fall, feed begonias, fuchsias and container plants. Always water before fertilizing.
* Fertilize fall-blooming perennials, too. Chrysanthemums can be fed until the buds start to open.
* Prepare for a fall full of flowers by paying a little extra attention to your garden. Cut off spent blooms from roses, annuals and perennials, then give them a boost of fertilizer. Make sure to water plants before feeding. Roses will rebloom about six to eight weeks after deadheading.
* Indoors, start seedlings for fall vegetable planting, including bunching onion, cabbage, broccoli, cauliflower, kale, radicchio and lettuce.
* Sow seeds of perennials in pots for fall planting including yarrow, coneflower and salvia.
