When is the best time to fertilize your lawn

When is the best time to fertilize your lawn? The warmer weather is approaching or is already here and you might be asking yourself do I fertilize in the spring or in the winter. Well the best time to fertilize your lawn happens to be in the spring.

It’s best to wait till your ground warms up to around 55 degrees Fahrenheit. Basically when you start to see your grass starting to grow again and the Lilacs starting to blossom. For most of us that’s around early to mid April.

Now that you know Spring is the best time to fertilize remember it’s not the only time because you should really fertilize your lawn every 4 to 6 weeks once you start till around October.

How Much Fertilizer Should You Use

How much fertilizer should you use? As you know fertilizer helps keep your grass nice and green while giving it the nutrients it needs to grow healthy. Think of fertilizer as your lawns food. Just like we need food to grow, grass needs fertilizer and the more fertilizer you feed it the more your grass will grow.

If you look on a bag of fertilizer you’ll notice the letters N – P – K which represents nirogen, phosphorus, and potassium in that order. Each ingreadent serving a purpose such as the nitrogen which helps keep your grass green.

For spring time fertilizer 20-5-10 seems to be a great mixture to start off with. If you are looking for something you can order online Scotts Turf Builder Weed and Feed Fertilizer is a great start.

Spreading Fertilizer

When Is The Best Time To Fertilize Your Lawn? Spring and what’s the best to way to spread your fertilizer? With a spreader. There are a number of reasons to use a spreader versus using your hands or just trying to manually spread fertilizer.

To start off with spreading fertilizer can be simple and very effective if done right. On the other hand if done wrong can do more harm and damage than good. For that reason you’ll want to use a spreader.

Spreaders can give you a consistent desired amount of fertilizer over your lawn without the worry of over feeding. When trying to spread by hand chances are you’ll end up with spots that have a lot more fertilizer than needed. This is not only bad for your grass but ends up costing you more in the long run.

One thing to watch out for when spreading fertilizer is to avoid overlapping rows which can end up causing strips in your yard. If you have a smaller yard and looking for a smaller spreader check out this neat hand held spreader.

Over Fertilizing

Over fertilizing won’t make your grass greener in fact it’ll do just the opposite as over fertilizing will end up burning and killing your grass. Even with a spreader you have to be careful not to over fertilize. A common mistake that homeowners make with a fertilizer spreader is using it with the spreading mouth wide open. As a rule of thumb a good starting point is to start with it half way open and adjust as needed.

It’s always better to use too little than to use too much. Also by starting with the spreader half open that’ll allow you to make a second pass over your lawn in a different direction to ensure better coverage. Avoid over-applying as much as possible.

Water Before or After You Fertilize Your Lawn

As you may know watering your lawn causes it to grow and the more it grows the more you need to fertilize it. The question is do you water before or after fertilization? It really depends on the type of fertilize you use as some fertilizers require moister and works better when the ground is soaked.

Watering your lawn to often will end up costing more as you’ll need to fertilizer more often. It’s recommend if you use a sprinkler system to fertilize your lawn about every 6 weeks. On the other hand if you don’t then you can get away with every 8 weeks.

If you water the grass after you fertilize your lawn be careful not to over water and wash away the fertilizer. This tends to happen on harder soil that’s had a dry spell.


So the best time to start fertilizing your lawn is in the spring and by using a spreader your grass will have a better chance of not being over fertilized. Be sure to check your brand of fertilizer for watering directions to ensure proper application.
