When Should You Fertilize Your Lawn for Fall? Understanding the Numbers on the Bag

 

When Should You Fertilize Your Lawn for Fall? Understanding the Numbers on the Bag

If you're standing in the lawn-and-garden section looking at bags of fertilizer, you may have wondered what all those numbers mean.

10-10-10.
15-0-15.
24-0-10.
21-3-6.

What do those numbers mean, and when is the right time to put fertilizer on your lawn?

As summer winds down, these are good questions to ask—especially if you want your lawn looking good going into fall and coming back strong next spring.

First, Know What Kind of Grass You Have

Before buying fertilizer, find out whether you have a warm-season or cool-season grass.

Warm-season grasses such as Bermuda, St. Augustine, and zoysia grow primarily during the warm months and go dormant when temperatures drop.

Cool-season grasses such as tall fescue and Kentucky bluegrass have a different growth pattern and are generally fertilized on a different schedule.

So don't assume that a "fall fertilizer" sold at the store is automatically right for your lawn.

What Do the Three Numbers on the Bag Mean?

The three numbers are the fertilizer's N-P-K analysis.

For example, a fertilizer labeled 24-0-10 contains:

  • 24% Nitrogen (N)

  • 0% Phosphate (P₂O₅)

  • 10% Potash (K₂O)

The numbers are percentages by weight.

Nitrogen — The First Number

Nitrogen is the nutrient lawns generally use in the greatest quantity.

It promotes green color and leafy growth.

That's why nitrogen is usually the first number people pay attention to when choosing lawn fertilizer.

But more isn't necessarily better. Too much nitrogen can cause excessive, rapid growth and create additional mowing and other problems.

Phosphorus — The Second Number

The second number represents phosphate.

Phosphorus is important for plant growth, including root development, but established lawns often don't need additional phosphorus unless a soil test indicates a deficiency.

Adding phosphorus when your soil already has enough can simply waste money and contribute to environmental problems.

Potassium — The Third Number

The third number represents potash, which is the fertilizer industry's way of expressing potassium.

Potassium plays important roles in overall plant function and stress tolerance.

Again, though, the best way to know whether your lawn needs additional potassium is through a soil test.

You Don't Always Need All Three

This is one of the most useful things to understand about fertilizer.

You don't necessarily need a fertilizer that contains nitrogen, phosphorus, and potassium every time you fertilize.

A soil test can tell you what nutrients your soil actually needs. Texas A&M AgriLife Extension recommends using soil-test information to determine phosphorus and potassium needs rather than automatically applying them.

If your soil already has adequate phosphorus and potassium, a fertilizer with nitrogen and little or no phosphorus may make more sense.

That's not only better for the lawn—it can save you money.

When Should You Apply Fall Fertilizer?

Here's where things get interesting.

For warm-season grasses, you don't want to fertilize simply because the calendar says August or September.

The grass needs to be actively growing and able to use the fertilizer. Fertilizing during severe heat or drought stress isn't a good idea.

Texas A&M recommends making the final nitrogen application no later than about six weeks before the expected first autumn frost, with the exact cutoff varying considerably across Texas. For example, its guidance lists October 1 for areas including Dallas and October 15 for Austin, Houston, San Antonio, and Waco.

In Oklahoma, the recommendation for warm-season grasses is generally earlier, with the final nitrogen application no later than September 15.

So if your lawn is suffering through extreme late-summer heat and drought, wait until conditions improve rather than rushing to fertilize.

How Much Nitrogen Does Your Lawn Need?

This is where reading the fertilizer bag becomes useful.

Suppose you have a fertilizer labeled:

16-4-8

The first number tells you that the fertilizer is 16% nitrogen.

If you wanted to apply 1 pound of actual nitrogen per 1,000 square feet:

1 ÷ 0.16 = 6.25 pounds of fertilizer

So you would need approximately 6.25 pounds of 16-4-8 fertilizer per 1,000 square feet to provide 1 pound of actual nitrogen.

If you wanted only ½ pound of nitrogen:

0.5 ÷ 0.16 = 3.125 pounds

That's why two bags that look very different can actually provide similar amounts of nitrogen—you have to look at the numbers.

Texas A&M gives the same calculation method in its lawn-fertilization guidance.

Don't Fertilize a Heat-Stressed Lawn Just Because Fall Is Coming

This may be the most important point for gardeners dealing with a hot August.

If your lawn is brown or struggling because it isn't getting enough water, fertilizer isn't necessarily the answer.

For example, Texas A&M's Bermuda lawn guidance specifically advises against fertilizing during hot, dry periods when moisture is limiting. Nutrients are taken up most efficiently when the grass is actively growing and not under heat or drought stress.

Sometimes the best thing you can do for the lawn is wait.

A Soil Test Can Save You Money

If you've never had your lawn soil tested, consider doing it before buying fertilizer.

A soil test can tell you the soil's pH and help determine whether phosphorus and potassium are actually needed.

That can keep you from buying fertilizer simply because the bag has an attractive picture of a beautiful green lawn on the front.

The best fertilizer is the one your lawn actually needs.

What About "Winterizer" Fertilizer?

You'll see products marketed as "winterizer" or "fall fertilizer."

Don't assume that the word on the front of the bag tells you everything you need to know.

Turn the bag over and look at the N-P-K numbers.

Then ask:

What kind of grass do I have?

Is it actively growing?

What does my soil need?

Am I still far enough ahead of the first frost for the fertilizer to be useful?

Those questions are more important than the word "winterizer" printed on the package.

A Simple Rule for the Budget Gardener

Before buying another bag of fertilizer, remember:

Know your grass.
Know your soil.
Read the numbers.
Don't fertilize just because the bag tells you to.

Understanding N-P-K can help you make a better decision and avoid spending money on nutrients your lawn doesn't need.

And sometimes, saving money on fertilizer is just as much a part of budget gardening as saving money on plants and seeds.

Happy gardening!

How to Turn Green Tomatoes Red: 7 Ways to Ripen Tomatoes at Home

 

There is something frustrating about watching a tomato grow to full size, only to have it sit there stubbornly green.

If you've got a garden full of green tomatoes and you're wondering how to get them to turn red, don't give up on them yet. Once a tomato has reached the mature-green stage, it can continue ripening after it is picked.

Here are seven ways to help your green tomatoes make the trip from green to red.

1. Let Them Ripen at Room Temperature

Sometimes the simplest method is the best.

Place mature-green tomatoes on a counter or other location at room temperature and let nature take its course. Tomatoes produce ethylene, a natural plant hormone involved in ripening.

Keep them out of the refrigerator while they are ripening. Cold temperatures can interfere with the ripening process and affect flavor.

2. Use a Paper Bag

The old paper-bag method really does have some science behind it.

Place a few mature-green tomatoes in a paper bag and loosely close the top. The bag helps concentrate the ethylene produced by the tomatoes.

Check the tomatoes regularly and remove any that begin to ripen or show signs of decay.

3. Add a Ripe Banana or Apple

Want to give the paper-bag method a little boost?

Put a ripe banana or apple in the bag with the tomatoes. Both fruits produce ethylene, which can encourage ripening.

Don't pack the bag too tightly. You want to be able to check the tomatoes regularly and remove any that begin to spoil.

4. Try a Cardboard Box

If you have more tomatoes than will comfortably fit in a paper bag, a cardboard box can work well.

Place the tomatoes in a shallow box rather than piling them several layers deep. You can put a ripe banana or apple in the box as an additional source of ethylene.

Check the tomatoes every few days and remove ripe or damaged fruit.

5. Wrap Them Individually

Another traditional method is to wrap individual mature-green tomatoes in newspaper or paper.

Place the wrapped tomatoes in a box or on a shelf in a cool location. Check them regularly and remove the paper from tomatoes as they begin to color.

This method is particularly useful when you have a large harvest that you want to ripen gradually.

6. Bring the Plant Indoors

If cold weather is approaching and you still have a lot of green tomatoes on the plant, there is another option.

You can pull up the entire tomato plant and hang it upside down in a cool, dark location. The tomatoes can continue ripening on the plant, and you can pick them as they begin to color.

This method isn't practical for everyone, but it can be useful at the end of the growing season.

7. Pick Them When They Begin to Blush

You don't always have to wait until a tomato is completely red before picking it.

When a tomato begins showing its first hint of color, it has entered the breaker stage and can finish ripening off the vine.

Picking tomatoes at this stage can be especially useful when weather, pests, or other problems threaten the crop.

How Do You Know If a Green Tomato Is Ready?

This is an important part of the process.

Not every small green tomato will successfully ripen after picking. You want a tomato that has reached the mature-green stage.

A mature-green tomato is generally full-sized and firm. The color may have changed from a deep green toward a lighter, whitish green, and the fruit has developed internally enough to continue the ripening process.

Immature tomatoes may simply shrivel instead of turning into a good ripe tomato.

Tomatoes Don't Need Sunlight to Turn Red

Here's something that surprises many gardeners:

Tomatoes don't need direct sunlight to ripen after they're picked.

Warmth is more important than sunlight. A temperature around the upper 60s to about 70°F is favorable for relatively quick ripening, while cooler conditions slow the process.

So putting a green tomato on a sunny windowsill isn't necessarily the secret to turning it red.

What About Tomatoes That Won't Turn Red?

Temperature can be part of the problem.

Very high temperatures can interfere with the production of the pigments that give tomatoes their red color. That's one reason gardeners sometimes find themselves staring at large green tomatoes during a hot summer.

In extremely hot weather, the tomato may continue developing without turning red as quickly as expected.

That's particularly interesting for gardeners in places such as Texas, where summer temperatures can remain very high.

Don't Forget the Green Tomatoes

Before you decide those green tomatoes are a lost cause, give them a chance.

Whether you leave them on the counter, use a paper bag, add a ripe banana, wrap them individually, or bring the whole plant indoors, there are several ways to help mature-green tomatoes finish ripening.

And if some of them simply refuse to turn red, there's always another possibility:

Fried green tomatoes!

Happy gardening!

Best Seeds and Plants to Grow in Texas This August

 

Best Seeds and Plants to Grow in Texas This August

August may be one of the hottest months of the year in Texas, but don't let the heat fool you. It's an important month for gardeners who are planning ahead for a productive fall harvest. With the right seeds and plants, you can keep your garden growing while preparing for cooler weather.

Whether you're an experienced gardener or just getting started, August offers plenty of opportunities to grow healthy vegetables, herbs, and flowers without spending a fortune.

Best Vegetable Seeds to Plant

Many vegetables can be started from seed during August in Texas. Depending on your location, consider planting:

  • Bush beans

  • Southern peas

  • Cucumbers

  • Summer squash

  • Swiss chard

  • Mustard greens

  • Collard greens

  • Turnips

As temperatures begin to cool later in the month, you can also prepare for cool-season crops such as broccoli, cabbage, carrots, lettuce, spinach, and kale.

Herbs That Love Warm Weather

Herbs are one of the best investments for a budget minded gardener. A single plant can provide fresh flavor for months.

Good choices include:

  • Basil

  • Oregano

  • Thyme

  • Rosemary

  • Parsley (late August in many areas)

Many herbs can also be propagated from cuttings, helping you grow your herb garden without buying additional plants.

Color for the Garden

If you'd like to add color to your landscape, August is also a time to think about hardy flowers that can brighten your garden as summer transitions into fall.

Depending on your area of Texas, consider flowers such as:

  • Marigolds

  • Zinnias

  • Celosia

  • Black-eyed Susans

Choose varieties suited to your local growing conditions for the best results.

Choosing Healthy Plants

If you're buying transplants instead of starting from seed, look for:

  • Healthy green leaves

  • Strong stems

  • No signs of insects or disease

  • Moist, healthy roots

  • Plants that are not root-bound

Healthy plants establish more quickly and usually produce better results.

Water Wisely

New seeds and transplants need consistent moisture while becoming established.

Water early in the morning whenever possible. Adding mulch around your plants helps conserve moisture and keeps the soil cooler during hot Texas afternoons.

Budget Gardening Tip

Before buying new seeds, check what you already have. Many seed packets remain usable for more than one growing season if they've been stored in a cool, dry place.

Saving seeds, propagating plants from cuttings, and reusing containers are all excellent ways to stretch your gardening budget.

Need Quality Seeds?

If you're looking for seeds for your late-summer and fall garden, take a look at the selection available through the Shop Seeds Now link in the sidebar. It's an easy way to find a wide variety of vegetables, herbs, and flowers for your next planting season.

Final Thoughts

August is a month of preparation as much as planting. By choosing the right seeds and healthy plants now, you'll be setting yourself up for a productive fall garden.

Remember, successful gardening isn't about spending the most money—it's about planning well, planting wisely, and making the most of every season.

Happy gardening!
