How to choose the best fall lawn fertilizer for a lush yard in spring

Here are some amazing fertilizer options to use this fall

When summer comes to a close, it’s time to find the best fall grass fertilizer for your grass to keep your landscape looking healthy and strong come spring. Winter can be harsh on your yard, and the last thing you want is a barren or muddy landscape once spring finally arrives. Thankfully, there are plenty of “winterizing” lawn fertilizers made to treat your grass to ensure it’s healthy and lush as the weather starts to warm.

However, while there are many brands to choose from, not all fertilizers are created equal. What fertilizer should you use in the fall? We’ve rounded up our favorite lawn fertilizers to help you control weeds and maintain fresh, green grass throughout spring.

What fall fertilizer does for your lawn

A common misconception by homeowners is the idea that all fertilizers work in the same way. However, that is far from the truth. Fall fertilizer doesn’t perform the same functions as spring fertilizer. Fall fertilizers are often made to improve healthy root growth, add nutrients and minerals back to the soil, prepare seeds for frosts, drought, or heat, and encourage new growth in the spring.

When using fall fertilizers, most people intend to “feed” the lawn to retain nutrients within the soil. Additionally, many homeowners pair their fertilizers with new grass seeds in order to take advantage of the nutritional benefits for seedlings to sprout by next spring.

Below are some of our favorite fall fertilizers. Each performs a different function depending upon your needs.

Espoma EOFW30 Organic Fall Fertilizer

If you’re looking for organic fertilizers, Espoma is a brand that avoids using harsh chemicals or byproducts within their fertilizer. This fall fertilizer is made of feather meal poultry manure as its main component. Sulfate of potash is another key ingredient that allows Espoma to stand out amongst the rest. This ingredient introduces natural potassium and sulfur to your lawn to encourage the production of healthy soil nutrients.

What’s most impressive about this fertilizer is that it has water-soluble and all-natural components. There is no reason to worry about harsh chemicals being drained into nearby water systems, as the materials are all non-toxic and organic.

Jonathan Green & Sons

Jonathon Green & Sons fertilizer is best for homeowners who are eager to plant grass seeds that will grow next spring. For barren and dry landscapes, planting seeds in winter can allow the grass to take root and sprout. However, winter frosts and excessive moisture can hurt seeds, hindering them from growing in the spring.

This fertilizer by Jonathan Green & Sons encourages root growth and creates optimal conditions for seeds to grow next season. You can add this fertilizer to your lawn before or after you have scattered the seeds. Over the winter months, the grass will take root and provide nutrients that benefit plant growth.

Scotts Turf Builder WinterGuard

Scotts Turf Builder is a great fall fertilizer to add nutrients and security back to your soil. As the seasons change, the soil is prone to drought, overheating, and frosts that damage roots. This fertilizer aims to prepare roots for winter by strengthening them so that once spring arrives, they can provide a lush green carpet across your lawn.

This fall fertilizer is specifically meant for feeding your lawn and promoting healthy root growth. While it doesn’t kill weeds, many lawn care experts recommend using fertilizers that encourage stronger grassroots over those that aim for killing weeds.

What to know when fertilizing your lawn

Before fertilizing your lawn, there are a few things you need to know.

First, fertilizers can perform two different functions. They can prevent the growth of weeds, or they can feed the preexisting grass in your yard. Some fertilizers have been able to do both, and those are considered “weed and feed” fertilizers. While killing weeds is often the main attraction for many homeowners when fertilizing their lawn, many experts argue that feeding your lawn and creating strong and healthy grassroots is far more important.

It’s also recommended that you follow fertilizing instructions to prevent overfeeding your lawn. Overfertilization can cause your grass to turn brown and die, which is the opposite of your goal when using fertilizer. Many fertilizers perform best when spread across your lawn at the recommended measurements. Additionally, it’s best to wait four to six weeks between each fertilizing session.  Preventing overfeeding isn’t just good for your lawn — this reduces the risk of fertilizer runoff, which could end up polluting your local waterways.

Typically, you only need to fertilize twice in the fall season. If you choose to fertilize once, use a product with a high proportion of nitrogen. If you fertilize twice, use a nitrogen-rich fertilizer the first time and a potassium-rich fertilizer the second. (All fertilizers are labeled with three numbers, which represent the ratio of nitrogen, phosphorus, and potassium.)

While there are specially made fertilizers for every season, fall fertilizers tend to better benefit the health and wellness of your lawn’s soil. They add a solid foundation for root growth and prepare seeds to sprout in the spring. Be mindful to follow the directions on your fertilizer’s packaging to ensure you are not over or under-feeding your lawn.

A pest problem in your home is certainly gross. In addition to the unwanted presence of creepy crawly invaders, many pests also carry diseases that create unsanitary conditions. Some can even cause serious damage to your home. A full-blown infestation can be extremely difficult to get rid of, potentially costing you a lot of time, money, and effort.

That's why the best pest control practices are preventative ones that keep bugs out of your house and stop infestations before they start. Developing a pest-prevention schedule includes periodically spraying your house for bugs to discourage their presence and stop them in their tracks before they start nesting and breeding. Timing is crucial here, so we're going to discuss the best time of year to spray your house for bugs and why it can make or break your pest control strategy.

This is what you should be planting in fall for a beautiful spring garden
Plant these seedlings in the fall and watch them grow in spring
Spring flowers forget-me-not

If you want a beautiful garden next spring, it's best to get to work now and start planting in the fall. Autumn is the perfect time to clear new garden beds, build pathways, add architectural elements, and of course, plant. Fall is also the ideal time to install cold-hardy plants because pest populations will dwindle, and plant growth patterns will turn in your favor.

The cooler autumn air is much more forgiving, and the still-warm soil offers an ideal environment for deep root development. And although your new garden plants will be going dormant soon, their roots will continue to grow through fall, until the ground freezes. This gives them an immense head start, as they'll have two seasons (fall and spring) to deepen and strengthen their roots ahead of next summer’s dry heat. As you plan your garden for the year ahead, consider planting these seedlings right now.
