Gardening column: Lantana lace bugs | Columnists


Lace bugs may possibly be sipping on your crops.

These little bugs have piercing-sucking mouthparts. They insert their needle-like mouthpart into a leaf to slurp out vitamins like a bitter smoothie. Leaves start out to glance speckled as the cells close to the insertion stage die. As feeding proceeds, the foliage will begin to glance stippled and bleached.

Lace bugs are all about the Lowcountry and usually go unnoticed. I detected them a handful of months back on lantana. The lantana lace bug is complicated to spot. They are smaller and tan and go unnoticed with a look. The indicators, however, are conspicuous. New advancement begins to curl at the edges and die again. Foliage gets rigid and distorted. The harm isn’t heading to eliminate the plant, but when it will come to lantana, we shed its most beneficial asset: it’s bouquets.

Lantana is generally applied as a perennial in the Lowcountry. The flower colour and dimensions depend on the selection, but the most popular kind grows a foot or so tall with yellow flowers. It does very best in total sunlight and perfectly-drained soil. It’ll cope with drought effectively. When healthy, lantana will bloom through the increasing period. And it’s not just the shade of the bouquets which is so desirable, but the numerous butterflies they appeal to. Despite lace bugs feeding on it, lantana survives 12 months just after calendar year. It has all the attraction of an annual flower with no acquiring to replant the subsequent yr.

Lace bugs arise on other vegetation in the Lowcountry. They are an annual pest on azaleas. Azalea lace bugs look distinctive from lantana lace bugs. They have membranous, lacy wings which is the attribute that offers the insect its identify. Lantana lace bugs are a dull-wanting bug. Lace bugs also feed on sycamore trees and pyracantha shrubs.

Most generally, you won’t see lace bugs. By the time you discover the minor white specks from exactly where they’ve fed, valuable organisms will have cleaned them up. In the landscape, crops tolerate lace bugs without having a issue to their wellness. In severe circumstances, I’ve noticed azaleas glimpse virtually white and continue to return the future 12 months.

The unique dilemma with lantana lace bugs is how it impacts flowering. Azaleas only flower for a pair of months and are performed by the time we see indications on the foliage. Lantanas flower all summer season long. Lace bugs put a cease to that. That is the trouble.

Start out scouting lantanas in early April. If you locate their presence early, they can be addressed prior to problems occurs. Horticultural oils or insecticidal soaps are the most secure products to use and will have no impact on valuable organisms that support in control.

In most conditions, we won’t discover lace bugs till the flowering stops. At this position, the least difficult approach of manage is pruning. Cut back again about a 3rd of the stems. Lace bugs have a tendency to feed at the guidelines of branches wherever the expansion is succulent. Pruning will take out any lingering offenders and promote new development. If lantana is healthy, flowering will ordinarily return in a number of weeks.

Really don’t stress how a great deal you prune. Lantana is unbelievably hardy. Even if it’s pruned back all the way to the floor, it will get better. It’ll just acquire a very little a lot more time for the flowers to return. Like most herbaceous perennials, new growth will arise from the base of the plant, referred to as the crown.

Lantana will die again to the ground at 1st frost. The stems and foliage can look a bit trashy in the landscape. Ordinarily, it is suggested to keep away from pruning the lifeless best expansion until March. If, even so, you seriously never like this search in your backyard garden, pruning back in early wintertime will, in most conditions, not harm the plant. You are going to see a full restoration in spring. The lace bugs will be waiting around. You can be completely ready for them.
