It’s literally freezing outside, but I took some moments to do a little bird watching. Since my office borders the waterway, I see a great many waterfowl around.
Last year, I saw an eagle catch a fish, land about 100 yards away and proceed to feed. Awesome sight. Today, despite the freezing temperature – or perhaps because of it – water birds are congregating.
Herons, both great blues and whites, mallards, black-bellied whistling ducks, cormorants, a few terns and a gull all depending on the water for a meal.
Mallards are migratory, but some live here all year long. Along the waterway, there are four drakes, one of which is an albino, who have masterfully kept all other drakes out of the area. I have seen fewer hens, although twice mallard hens have built nests in our parking lot and hatched eggs…waddling to the water with the ducklings in tow. Once, a duckling was left in the nest. One of the caring souls here took it home and added it to their small flock of domestic ducks. The little fellow grew to adulthood, only to be eaten by a hungry fox.
While cormorants and black-bellied whistling ducks tend to be around all year, there are more of them flying around in the winter. Both species are migratory.
Cormorants tend to spend their winters along the southern coastal states, but also winter in Oklahoma, Arkansas add eastern Tennessee. They spend summers in their breeding grounds of the northern states (Idaho, Montana, The Dakotas, and Canada – although they might extend east into Minnesota and Michigan.) However, some cormorants live along the Gulf Coast all year as well. People often see them on the edges of waterways with their wings outstretched. Because they are diving birds, their feathers tend to become waterlogged. They stretch their wings to dry the feathers. Cormorants can dive up to 25 feet.
Black-bellied whistling ducks are native to the valley and to Mexico, but they do like to overwinter here. As with all the migratory birds however, some live here all year long. These birds nest in mesquite, hackberry, willow, live oak and other trees. They especially like cavity nests in dead trees. They actually do whistle, and look more like geese than ducks. Ornithologists are recording that they are expanding the northern part of their range.
Great blue herons. These large birds feed on just about anything they can catch and swallow. While their favorite food is fish, they will eat ducklings, rats, mice, and other small mammals, frogs, and other birds. Although some are migratory, many of them do not migrate. Last year, a great blue with a broken wing wandered into as parking lot near here. The animal was almost as tall as me. A park ranger and myself finally cornered him, and with the help of a cast net, finally capture it. I took it to animal rehab where they repaired its wing and released it back into the wild. Great blues are a federally protected bird.
Great white heron. Also federally protected, the great white, unlike its more sedately colored cousin, tend to not migrate, although, even if they do, their range is limited. Those along the Gulf Coast are generally permanent residents.
There are several elegant common terns in the lake as well. They spend their summers mostly in Central Canada, but their winter migratory regions encompass most of the coastal United States and Mexico.. Terns will fly over water, hover there, and them plunge to catch prey. Sometimes they will also pursue insects on the fly.
Q. I have trees in my yard, and the grass doesn’t want to grow well under them. What can I do? A. Remember that grass is a plant too, and requires sunlight to convert energy to food. Of all the turf grasses that are adaptable to southeast Texas and south Louisiana, St. Augustine grows best in shaded areas. However, if it can’t get any sunlight at all, it will cease to grow under your trees. If your grass is getting thin in under-tree areas, you might think of hiring an arborist to do some minor pruning on your trees to allow more sunlight in.
Q. Is now the right time to use a “weed and feed” product? A. NO time is the right time to use weed and feed products. The proper time to apply the pre-emergence herbicide used in this product is before the weeds begin to grow…late February to early March. The proper time to fertilize or “feed” turf is mid-April. Applying them both at the same time is a waste of time and money. Applying “weed and feed” too early, and the fertilizer is dissipated or leached out of the soil by the time the grass needs it. Applying it too late, and the “weed” part has no purpose, because the weeds have already emerged and seeded.
Q.Why is the soil under my lawn rock hard? A.Too much water, too many salt-based fertilizers and pesticides, too little organic matter in the soil are primary causes of hard soil. It has become compacted, making it harder for grass roots to penetrate. Pull up a handful of grass, roots and all. If the roots are shorter than three inches, your soil is too hard for the roots. Good St. Augustine, for instance, can grow roots as deep as at least six feet.
Q.What can I do to fix this? A. Aerate your yard. Then add a half-inch of organic material (compost) across the top of your lawn. The compost will enter the soil and the aeration will help water and air to penetrate it (roots need air and water too).
Q. When is the best time to sod my lawn? A.Springtime (April and May) or early fall (October) are the best times to lay sod. So, now’s a good time to resod. Remember to add organic material when you do resod.
Q. How often should I water my lawn in late spring and summer? A. St. Augustine needs only one inch of water weekly, and even less if it rains. However, that doesn’t mean you NEED to water twice a week. For 2017, experts and empirical data have indicated that, because of rain and high humidity, we needed to irrigate lawns only 12 weeks out of the entire year. And about half of that time, we didn’t need to irrigate more than one time during the week. The best way to gauge how much to irrigate is to have a rain sensor installed (they’re very inexpensive – about $20.) or install a Smart controller.
Every year about this time, residents began calling to report their grass is dying. Their beautiful, green, lush St. Augustine has turned a sickly brownish yellow. They worry that it’s not getting enough water, so they water profusely. They think that some disease or insects may be attacking their lawn, so they pile on pesticides, fungicides and fertilizers.
The fact is that St. Augustine grass is supposed to look brown and dead in the winter. However, St Augustine is a warm season grass. When the soil temperature drops below 55 degrees, the grass goes dormant.
Homeowners shouldn’t panic, nor should they use the myriad of panaceas offered on the market.
Watering during the winter
This is not a recommended practice. Fungal infections are particularly damaging to turf grass. And what causes fungal infections? We don’t see too many fungal infections in the desert. It’s humidity and wetness that fungi like. Watering lawns during the winter is the major cause of fungal infections. The damage is done when the grass is dormant, so the infections are not visible then. Come spring and early summer though, and the presence of fungi is evident from the great yellowing patches of turf. By then, the damage has already been done. Instead of spending bucks on fungicides, just stop watering. We get enough rain in the winter to provide what little water St. Augustine might require.
Planning for Spring
Now is the time to get ready for springtime. A soil test might be a good idea. Both Texas A&M and LSU offer a great soil test for about $15. Use your computer search engine to browse for Texas A&M Soil Testing or LSU Soil Testing. There are explicit instructions on how to take a soil sample, how to fill out an application and how to send the whole package. St. Augustine turf does best in soil with a pH of around 6.5. The test will provide good, empirical data which will help in maintaining a healthy and green lawn in spring, summer and fall.
