Question of the week

<%=tDate%>

Q. It looks like I’ve already got brown patch in my lawn. What can I do about that and to protect my other plants from fungal disease?

A. With our wet, cool weather, gardeners are seeing a lot of fungal problems in lawns, perennials, and shrubs. For brown patch, the best thing to do now is prevent it. Does the area capture water? Is it compacted?

Aerate the area—even with the tines of a spading fork—and layer with about ¼” of compost. Don’t over water this summer, and don’t douse it with fertilizer. Prune trees to provide more sun.

You can apply corn meal or spray with a baking soda or potassium carbonate solution: 4 tsp. to a gallon of water, and a few drops of liquid soap. I add a little liquid seaweed to the mix to build up the plant’s health (lawn or perennial).

You can also try Actinovate, a commercial product containing beneficial microorganisms that helps plants fend off disease. Still, prevention by creating a healthier situation will save you time and worry in the long run.

Producer note on lawns: A few years ago, I had some work done on my house. Between the construction materials and weeks of rain, the strip of grass adjoining my patio—the pets’ traffic area—was compacted mud. I figured it was hopeless. By then, I was out of money, so I just took a spading fork and poked a lot of holes and spread some of my homemade compost.

Then, I sprinkled dried molasses (available from nurseries who carry Rabbit Hill organic products), and sprayed with liquid seaweed. A few months later, the grass came back, healthier than it had ever been in this well-traveled area. Now that I have a new dog that plays ball along this strip, I may repeat this process!

Of course, it helped that I built a stone patio—extended from the original broken cement rectangle—to cover the low-lying area, eliminating a lot of grass. That’s why I was out of money! So, if you have an area that’s always a problem, like mine was, reduce its size or create a new garden path or bed, my usual resort to go along and get along with little fungal maintenance.

To protect your roses and other perennials from fungal diseases and insects like scale, spray now with neem oil. Dicke Patterson from It’s a Jungle recommends Dyna-Gro, which is pure neem.

The bluebonnet may be the official symbol of our state when it comes to wildflowers, but when it comes to native landscape plants, Texas Mountain Laurel is the poster plant.

It produces dark green foliage and tolerates our thin limestone soils, but still does well on deep fertile soil. It just needs great drainage. Although its growth rate is slower than Molasses, it is well worth the wait.

The purple spring blooms leave the air laden with a heavy, grape bubble gum or grape Kool-Aid aroma. The red seeds are poisonous. Texas Mountain Laurel can grow to over 20 feet in some conditions, but for practical purposes it is usually considered to be about a 10 to 15 foot shrub/tree. It makes a great specimen plant but also works well planted in a row down a property line to form a loose evergreen screen.

Planting tips of the week
  • Keep pulling weeds! At this point, chemicals do you no good. We’re still a few weeks away from our last frost date, so I’m holding off on planting summer-flowering plants from seed.
  • But it’s an excellent time to get all those perennials in the ground. Don’t wait until they’re seductively flowering at the nursery; they’ll get a better start if you get them in the ground now.
  • You can get your tomatoes now, but pot them up for safety to plant in a few weeks.
