Let’s talk about why lawn fertilization is so important before we get into the details of how often you need it. Lawn fertilizer is very important for replacing nutrients that grass loses over time. Water runoff, caused by things like rain and irrigation, takes nutrients out of the earth by dissolving the nutrients in water.

If these nutrients aren’t in the soil the grass turns weak, becomes prone to disease easily, and weeds can grow in it.  You should always give your grass the nutrients it needs to grow by using lawn fertilizer. Some of these nutrients are nitrogen, phosphorus, and potassium.


What Does a Lawn Fertilizer Do?

For grass to grow properly, lawn fertilizers are carefully made to replace the nutrients that grass needs. Each nutrient serves a specific purpose:

  • Nitrogen: Nitrogen is what makes grass grow quickly and turn a bright green color.
  • Phosphorus: Phosphorus helps grass root systems grow strong, which keeps the grass stable and healthy.
  • Potassium: Adding potassium to grass makes it stronger and enhances the grass’s ability to resist drought, cold, and diseases.

A lawn that has been fertilized not only looks nice but is also better able to handle things that are bad for it in the environment. Okay, now that we know why lawn fertilization is important, let’s look at how often we should fertilize lawns in Texas.

How Often Should I Fertilize My Lawn in Texas?

When it comes to how often you should fertilize your lawn in Texas, you should think about several things. Some of these are the type of grass, the weather, the state of the soil, and the amount of shade. Let’s look at each of these factors.

Grass Types in Texas

There are different types of grass in Texas, and each one has its own needs when it comes to fertilizer. Knowing what kind of grass you have in your lawn will help you choose the best fertilizer and when to apply it. Here are some popular grass types in Texas:

  1. Bermuda grass: This is a warm-season grass that does well all over Texas. It is gray-green and is highly drought-tolerant. During its growing season, which usually lasts from late spring to early fall, it needs to be fertilized often. During this time, you should fertilize bermudagrass every 6 to 8 weeks.
  2. St. Augustine grass: St. Augustine grass is well-suited for central Texas. it grows quickly and can withstand heat or shade. During the late spring to early fall, you should fertilize St. Augustinegrass every six to eight weeks.
  3. Zoysia grass: This type of grass grows well in Houston. It is weed-resistant and can withstand a bit of shade. You can fertilize Zoysiagrass every 6 to 8 weeks during the active growing months.
  4. Buffalo grass: This grass doesn’t need much care and grows well in West Texas. Compared to other types of grass, it needs less water and care. During its growing season, which is usually from late spring to early fall, it usually does better with one or two light doses of fertilizer.
  5. Tall Fescue: Tall fescue is a cool-season grass that does well in the northern parts of Texas. In the winter, it can handle a fairly cold climate, but in the summer, it needs more water. They have different fertilization needs compared to warm-season grasses and generally benefit from fertilization in the spring and fall.


Climate and Weather Conditions

Texas has a wide range of climates, with different areas having different weather trends. The best time to fertilize your lawn will depend on the temperature and weather in your area. There are four main areas in Texas: the Rio Grande Valley, South Texas, Central Texas, and West/Northwest Texas. Let’s look at the best time to fertilize plants in each area:

  1. Rio Grande Valley: Around March 1 is the best time to start fertilizing in the Rio Grande Valley.
  2. South Texas: For South Texas, the recommended start date for fertilization is around March 15th.
  3. Central Texas: Fertilizing should start between April 15th and May 1st in the middle of Texas which runs from El Paso to Dallas.
  4. West/Northwest Texas: Around May 15 is the best time to start fertilization in West and Northwest Texas.

Please note: these dates can change yearly based on the weather, so it’s important to keep an eye on your grass’s growth and make any necessary changes to the fertilization schedule.


Soil Condition and Type

The type of soil in your lawn greatly affects how much and what kind of fertilizer you use. Texas has four main types of soil: chalky, sandy, clay, and loamy. Each type of soil has its properties that affect how healthy and nice your lawn looks. For example:

  • Sandy soil, which is common near the coast, drains quickly and needs to be watered and fertilized often.
  • Clay soil, common in the eastern and central parts of the state, holds water well but can get hard, which makes it harder for plants to absorb nutrients.
  • Loamy soil is made up of sand, clay, and silt. It is found in the northern part of Texas. It drains well and can hold a lot of nutrients.
  • In the western parts of Texas, you can find chalky earth that is high in calcium carbonate. It is mostly alkaline, and changes may be needed to bring the pH levels back to a healthy level.

To find out exactly what nutrients your soil needs, you might want to do a soil test. A soil test will tell you a lot about the pH balance and nutrients in your soil, which will help you choose the right type of fertilizer and the right amount to use.


Shade and Sunlight Exposure

The grass on your lawn also needs different amounts of fertilizer depending on how much shade or sun it gets. Areas that are shaded need less nitrogen than those that are in full sun. Grass in shady areas only needs half to two-thirds as much nitrogen as grass that gets full sun.

The best time for grass to use nitrogen is when its leaves are open to light. Because of this, grass that grows in shady spots should be fertilized in early spring and late autumn.

You can make a custom fertilization plan for your lawn by taking these things into account: grass type, climate, soil state, and shade. You can get the best results and keep your lawn healthy and green all year by adjusting the fertilization plan and type of fertilizer to your lawn’s needs.

Best Fertilization Schedule In Texas

Now that we’ve talked about the different things you need to consider when fertilizing your lawn and how often you need to fertilize the lawn, let’s figure out the best time to fertilize your lawn in Texas each season.

Spring Fertilization

Early spring is the best time to fertilize lawns in Texas because that’s when grass starts to grow. The exact time of spring fertilization may change based on where you live and the weather.

When to start fertilizing, though? In general, you should start in early to late spring, when the grass starts to turn green and show signs of active growth.

Applying fertilizer at this time gives the grass the nutrients it needs to grow healthily and recover from winter lethargy.

The ideal start dates for spring fertilization in different regions of Texas are as follows:

  • Rio Grande Valley: March 1st
  • South Texas: March 15th
  • Southeast Texas: April 1st
  • Central Texas (El Paso to Dallas): April 15th – May 1st
  • West/Northwest Texas: May 15th
  • Panhandle: June 1st

Remember that these times are only rough estimates and could change based on the weather in your area.


Summer Fertilization

Texas summers can be rough, with high heat and drought. To keep your lawn healthy and strong during this time, you should apply fertilizer twice during the summer. If you use a summer blend fertilizer, it will help protect your grass from heat stress and keep it growing and healthy.

Usually, the first round of summer fertilizer should be applied in early summer, around June, and the second round should be applied in the middle of summer, around July or August. These applications will give your lawn the nutrients it needs to stay healthy and bright during the hot summer months.


Fall Fertilization

In Texas, fall is also an important time to fertilize lawns. This will help it heal from the stress of the summer heat and get ready for winter. Fall fertilizer also helps the grass’s roots grow and makes it stronger, so it can handle the cooler weather and possible damage in the winter.

For the best results from fall fertilizing, it is suggested that you use fertilizer twice. In the late fall, around November, the second application should be made. The first application should be made in early fall, around September. With these applications, you’ll give your garden the nutrients it needs to stay healthy and strong all winter.


Winter Fertilization

Even though your lawn may not seem to be doing much in the winter, it is still important to give it the nutrients it needs to support root growth and get ready for spring.

It is very important to use a winterizing fertilizer mix that is high in potassium when you fertilize in the winter. Potassium helps grass use nitrogen and water well, stay green and strong in cold weather, and fight freezing.

Two doses of winter fertilizer are suggested: the first should be made in early winter, around December, and the second should be made in late winter, around February. These applications will give your lawn the nutrients it needs to grow well over the winter and quickly heal in the spring.
