The Phlox is Blooming

....and I couldn't be happier!

It's blooming in most gardens in Nashville, but I was worried that there would be no phlox in my summer garden. This past spring I discovered that Phlox Bug had infected my plants. Long time readers know that I go to great lengths to insure that that horrid life sucking bug never gets another toe hold in my garden...But, it did.

It's my practice to let the garden go to seed and stand all winter. (A Garden Cleanup Reminder) The seed heads and stalks of native plants provide winter interest and hiding places for  the critters who live and visit my garden. But, I never, ever, ever leave the stalks of Phlox paniculata. Trashing the dead leaves and stalks is an essential first line defense against the Phlox Plant Bug. But, in a garden like mine, where rough and tumble plants do their plant thing~set seed and make offspring all over the place~it's easy to over look a few stalks.

Why trash the stalks? That's where the Phlox bugs over winter! They emerge in the spring and wreck havoc on the plants.* So, this spring when they showed up in the garden, I went on a hunt and seek mission smashing every one of the little red buggers. They're fast, but, I was faster. I also chopped the infected plants down and disposed of the stalks in the trash (never in the compost pile).

The phlox that's blooming now is looking especially good and there's more blooms to come~

I couldn't be happier~I know the pollinators will be, too.

**  Lopidea davisi is a plant juice/sap sucking insect that feeds mainly on perennial phlox. This is not a pest to ignore. I found out the hard way! They can form dense populations and suck the life juices (sap) out of your plants. The clever little adults lay white-colored eggs in the fall in the stems of the plant, behind the leaf petioles. The eggs overwinter  and nymphs emerge in early May. Two or more generations could develop in a season.

A Garden Clean Up Reminder

Late winter is clean up time for wildflowers and grasses. By then the goldfinches have striped the rudbeckias, coneflowers, and agastaches bare of their seeds, the fluffy seed heads of the ex-asters have blown about the garden and the grasses which provide winter cover for small critters are looking ratty from the rain, wind and occasional snow falls.

But, I never, ever, leave the summer Phloxes standing all winter. Once they've been flash frozen I cut them to the ground and trash all the cuttings.

Phlox after a frost is still pretty, but it has to go. There might be bug eggs hiding!

Phlox Plant Bugs are tiny and fast moving critters that hide underneath leaves and make it hard to see and smush! So far they don't seem to be a tasty treat for the beneficial insects or birds that visit my garden. Perhaps, their orange and black coloration signals stay away to most insect eating critters.

The Phlox Bug~soon the leaves with turn yellow and die

It's easy to see how they could get established in the garden if we're not vigilant.  That's what happened here a few years back. I'm glad to say that I've finally gotten it under control.

 Phlox paniculata is a foundation plant at Clay and Limestone. The Bumbles, butterflies, skippers and a variety of pollinators rely on it for nectar and pollen during our dry and droughty summers. I count on it for color and beauty. It's a tough plant, but it needs help when challenged by a pest like Phlox Bug.

Here's what you can do starting right now to make sure it never gets a proboscis near your phlox!

• Practice good sanitation. Cut back and dispose of infested stems and leaves. Clean up stem and leaf litter in the winter. I cut back every stem I find and threw them in the trash, not the compost. Compost works if yours gets hot enough to cook bugs! Mine doesn't.
• Scout for nymphs and treat. Apply insecticidal soap to both the upper and underside of the leaves. Use a light horticultural or sunspray oil. I haven't had to up my treatment to this.

You might not have this pest in your garden, but, cutting back and disposing of the stems and leaves will go a long way to insure that you won't ever see one of these nasty pests on your Phlox.

Just in case you forget, I'll post about this next fall, too. I pinky swear!

PS Of course you know that I never, ever, ever, ever use pesticides in my garden. I love my bees and other pollinators and don't want to risk causing them harm.
