Key Takeaways
- Winter fertilizer strengthens cool-season grasses like fescue and bluegrass during dormancy.
- Benefits include improved cold resistance, pest prevention, and a stronger spring start.
- Apply in late fall or early winter before the ground freezes for best results.
- Use granular fertilizers for slow-release feeding; avoid applying before heavy rain.
As the days grow darker and shorter and garden growth slows, you might assume it’s safe to put the fertilizer away until the spring.
However, winter is often the toughest season on your lawn, second only to summer. That makes now the ideal time to apply fertilizer.
This ultimate guide to winter fertilizer from SunCo will fill you up with facts so you can care for your garden with confidence.
You can think of this as your FAQ about winter fertilizers, as we’ll answer your most burning questions about when to apply winter fertilizer and how much. Get ready to learn about winter fertilizers!
Do I Have to Fertilize My Plants in Winter?
The short answer? It depends. Like a lot of plant care, whether you should apply winter fertilizer on your lawn varies based on what you’re growing.
For example, cool season grasses like fescue and Kentucky bluegrass greatly benefit from a feeding of fertilizer during the cold months.
Even in their dormant state, the nutrients in fertilizer feed their roots, ensuring that they emerge strong and healthy in the spring.
The Benefits of Winter Fertilization
And that’s not all. You might not want to be the only gloved person applying fertilizer in the cold, but it’s worth it for these reasons:
Helps Plants Endure Winter Temperatures
Can your lawn endure the freezing temperatures of winter? Fertilization provides enough food and nutrients to hardy plants and grasses during their dormant phase that your grass survives freezing temperatures unharmed.
Prevents Diseases and Pests
Diseases and pests don’t stop just because it’s cold. Yet when you leave your plant to fend for itself for months, it’s tricky to say what will happen to it in the early spring.
Use winter fertilizer to help it build up disease and pest resistance until the weather thaws.
Sets Up a Successful Spring
The essential nutrients in fertilizer provide proper root system growth thanks to the inclusion of the macronutrient potassium.
Besides their abilities to handle cold weather and drought, fertilizer will immediately encourage root growth that prepares for a fruitful spring.
You’ll have a lush lawn earlier, with blooming flowers and healthy green plants that make each day in your garden a delight.
When to Fertilize in Winter
Like all fertilizer applications, timing matters. You don’t want the application to coincide with your fall fertilizer schedule, but you don’t want to wait until the ground begins freezing over, either.
The right time to plan for winter lawn fertilizer use is in late fall or early winter. You can usually begin in the middle of November or early December depending on your region.
If you fertilize too early, the treatment might not be effective. Plus, you risk overfertilization if your winter and fall schedules coincide.
However, if you wait too long, such as after the ground freezes, nutrient runoff can occur, also negating the efficiency of treatment.
Tips for Using Winter Fertilizer
You’re ready to choose the best winter fertilizer and get started. Good thing, as we’ve got plenty of tips for applying winter fertilizer to encourage root growth and jump start spring growth.
Choose the Right Kind of Fertilizer
With so many types of fertilizer (for winter or otherwise), you might feel stuck on which to choose. Liquid fertilizer is still valuable in winter, but not if the temperatures regularly drop below 40 degrees Fahrenheit.
Granular fertilizer is another option. This is easier to apply, as it goes straight into the soil and provides a slower, more gradual feed than liquid fertilizer. That means only reapplying fertilizer perhaps once per season (depending on the plant’s fertilization requirements) compared to the more regular application of a liquid product.
You can also explore specialized winter fertilizers, which often feature “winterizer” on the packaging. These products are made specifically for cool-weather grasses and plants.
Always Follow Application Instructions
One of the most important tips for using winter fertilizer is to follow the instructions on the package or jug. Those guidelines are there for a reason; to ensure you use the product safely and efficiently.
Don’t Use Before Heavy Rain
Rain can dislodge fertilizer granules and dilute liquid before your grasses and plants receive enough nutrients. Always check the weather forecast before fertilizing to ensure you don’t waste your products (and your time!).
