Summer Suggestions
As I walk around our neighborhood, I think about what I’d share with you if asked about your lawn
or trees or overall landscaping. That triggered me to offer you these few suggestions this summer.
Lawns
To have a healthy lawn there are just a few “musts.” You must water it deeply once a week to
encourage root growth. I water my grass on Wednesday mornings (City of Austin guidelines) before
sunrise for two 30 minutes cycles. Deep root watering yields lush green grass. My shrubs and
ground cover irrigation zones don’t need nearly as much water, but grass does.
Another “must” is to mow your lawn once every week. This prevents weeds and undesirable grasses
from having time to go to seed and take over your preferred grass species. So mow every seven days and mow it on a high mower setting. Tall grass (2 to 3 inch long blades) also encourages deeper roots. The taller the blade, the deeper the roots. The more water applied in one day’s watering, the deeper the roots and stronger the grass.
Xeriscaping
Since I just talked about lawns, are you considering doing away with that troublesome front yard
problem? Think twice. Xeriscaping does not mean zero maintenance because you no longer have a full lawn to deal with. In fact, there is usually more work involved to keep a xeriscape looking good.
You still will have to water trees and shrubs within your xeriscaped area and there’s a lot of
necessary weeding and other maintenance to keep it looking tidy. In theory it’s a good idea, but do
realize that there is so much more work to maintaining an attractive xeriscape.
Trees & Shrubs
February’s deep freeze affected much of our neighborhood's landscaping. Some trees died or leafed
out peculiarly this spring. Don’t remove this “epicormic” growth as photosynthesis must go on in
this survival mode trees are going through. Give every plant a chance. There should be no hurry to
remove dead or near dead trees or shrubs with just one exception. Palm trees that didn’t survive
should be removed before they come crashing down.

Now that we’re into our typical hot, dry summer, planting new trees, shrubs or perennials should be
held off until November or December. Since another 100-year deep freeze is likely to recur within
the next five to ten years, don't make your replacement choices the same plants you just lost.
Select hardier plants that are more freeze tolerant (and, for some of us, deer resistant too).
Mulch
Here in Central Texas it’s really a good practice to periodically apply a two to three inch layer
of mulch to your gardens. I do this every year. Mulch provides the benefits of helping the soil
retain moisture, stay cooler, while inhibiting weeds. Applying mulch shouldn’t just be a signal
that you’re about to put your house on the market. There really are a lot of great benefits to it
besides beautifying your property.
Summary
The formula to a good looking lawn free of weeds is to fertilize it in April, water it deeply
weekly, mow it weekly at a high mower setting. Don't xeriscape unless you are ready to take on more
maintenance than a lawn. Leave tree and shrub planting until the cool days of fall. Mulch now and
save your plants and water.
If you have questions about your yard or garden, please call Travis County Master Gardeners at
512-854-9600. If they don’t have an immediate answer, they’ll research it and get back to you.

Let's talk about L A W N S
But first, here are some post-winter freeze thoughts ...
Six days of sub-freezing temperatures this February has done a number on our landscapes. Some trees couldn’t handle the weight of the ice, so limbs snapped off left and right. Besides removing that debris, you should try to create a clean saw cut on the tree where the limb more than likely raggedly tore off. And if they were breaks on oaks, please paint the cuts immediately. The oak wilt threat is upon us through June. (See Tree article.)
Besides those tree clean ups, I have one other major suggestion. Be patient! Some shrubs, ground covers, perennials and other plants may look absolutely dead. However, there is a strong possibility that their root systems have survived. If you have succulents and cacti that have gone mushy, do remove that stuff, but for most all other plants, please do not give up on them. Wait until at least mid April before deciding what has recovered and what has not. So again I say, be patient with your landscape plants.
LAWNS
Our once green carpets of grass took a beating during the deep freeze too. Most will recover. Here are some suggestions of what you can do to strengthen your grass, be it Bermuda (full sun), St. Augustine (shade), Zoysia (sun/shade) or some other kind of grass.
Remove the thatch on your lawn either with a very close mowing and bagging or by raking it up. Either way, you need to get that dead grass off of your lawn. You might consider doing this one-time activity in conjunction with the spring drop of leaves coming real soon.
After that close cut, set your mower to cut high for the rest of the mowing season. Real high! Allowing your grass to grow tall means beneficially deeper root systems. (There truly is a correlation between grass blade height and root depth.) Mow your lawn once every week. Frequent mowing prevents weeds from popping up, going to seed and taking over.
DO NOT FERTILIZE your lawn until your grass greens up naturally. Mid April. Put that date on your calendar. It’s the earliest you should even consider fertilizing. But do you know what fertilizer to put down? With an urban soil test http://soiltesting.tamu.edu you would find out.
I’ll be the first to admit that my back lawn has weakened over the years. I’ve laid down new sod, it looks great for a while, then it peters out. When I received my soil test results this fall it indicated that my grass lacked sufficient nitrogen despite the fact that I was putting down fertilizer. My soil test also said do not apply any phosphorous (P) or potassium (K). So, this spring I’m going to locate a 21-0-0 ratio (or thereabouts) fertilizer, high in nitrogen, devoid of the other two nutrients, and apply that. So, test now (directions on the website form) so that by April you can be properly nourishing your grass.
Also, when applying the correct blend of fertilizer in April, do not use a combination weed killer/fertilizer. Your opportunity to eradicate weeds was back in January with a pre-emergent weed killer. Now it’s too late for that so hand pulling weeds is just about your only option.
The very best thing you can do for your lawn is to mow it weekly, mow it high. Let your green grass clippings fall back onto your lawn. Provide early morning watering each week (according to Austin watering schedule) when nature doesn’t provide sufficient rain.
A dense, healthy lawn of St. Augustine, Bermuda, Zoysia or other kind of grass will make most weed problems go away. And a beautiful, green, weed-free lawn, along with well cared for trees, adds a great amount of curb appeal and value to your home.
