Stop Weeds With
Corn Gluten Meal

The heat is finally beginning to break and next week low temperatures will drop down in the 70s with highs in the low 90s. Cooler weather means Fall weed seeds will start to germinate! Keep them from taking over your lawn with all-natural Corn Gluten Meal.

​

Corn Gluten Meal is a highly effective organic pre-emergent herbicide that, when used correctly, will significantly reduce lawn weeds. It works by preventing weed seeds from sprouting.

 

It's easy to apply to your lawn with any fertilizer spreader. Spread it in your beds as well to prevent weeds from cropping up there, too.

​

After application, water lightly to activate it. Corn Gluten Meal keeps working for up to 90 days to stop seed germination. And it's safe to use around kids and pets.

New Arrival:
Mexican Bird of Paradise

The Caesalpinia gillesii, known as the Mexican Bird of Paradise, is a tropical looking erect shrub with fine, soft foliage and yellow flowers with distinctive red stamens. Although it looks similar to its close relative, the Pride of Barbados, it is much more cold hardy (down to ~15°F!).

 

Mexican Bird of Paradise is also highly drought tolerant. Once established, it needs only infrequent deep watering in well-drained soil.

Texas-native-wisteria_Wisteria frutescens.png

Non-Invasive Texas Wisteria Minds Its Manners

Texas Wisteria (Wisteria frutescens) is much different from Asian Wisterias, which are invasive in Texas. This woody deciduous vine is a well-mannered substitute that gives you similarly massive and fragrant bluish-purple flowers along with shiny, dark green leaves. But while its vines can extend up to 30ft., its stems are much  thinner and less destructive to brickwork and trellises. As a native to the piney woods of East Texas, it prefers acidic soil.​

Save Your Lawn from Chinch Bugs!

Chinch bugs are tiny but highly destructive pests that chew up and kill  St. Augustine and Zoysia lawns, and they thrive in the summer heat. They often start near the edges and leave patches of brown, dead grass in their wake. And they can devastate your lawn in a matter of a week or two.

 

So there's no time to waste! If you think you have chinch bugs, treat your lawn today with Perma-Guard.

phytophthora_cozart-101227.jpg

Your Dead Plant Could Have a Disease

What's killing your plants? It could be a disease called Phytophthora Root Rot.

 

Phytophthora (pronounced “Fi-toff-thor-a”)  is an organism that lives in the soil, and under the right conditions, it can spread through your yard and kill your trees, shrubs, and even perennials.

 

Unfortunately, pruning off the dead branches won't fix the problem. And because Phytophthora isn't actually a fungus, fungicides don't help either.

​

We've had real success treating it with biologicals — beneficial bacteria that help fight back against Phytophthora naturally. This problem is serious enough that we're now treating the soil at all of our new landscape installations as a preventative measure.

 

If you're noticing anything like this in your yard, give us a call. We're happy to come take a look, help you figure out what's going on, and treat it for you — or we can set you up with what you need to treat it yourself.​​​​
