Weed and Feed vs. Fertilizer
Weed and feed products are a combination of weed killer and fertilizer. They’re usually granular because the slow-release of a granular formula is important for feeding your lawn long term. That said, there are liquid spray options available.
Most weed and feed fertilizers are meant to be spread over your entire lawn in late spring. This feeds the lawn before its growth accelerates in the summer and kills broadleaf weeds like dandelions.
Not all weed and feed products are formulated to kill grassy weeds but some are. The type of weed and feed that’s right for your yard depends on what kind of grass you have and the type of weeds you’re dealing with.
Fertilizers do not kill weeds, they only feed your lawn. There are a lot of different types of lawn fertilizers out there, including liquid or granular as well as chemical-based or organic.
When you only use fertilizer on your lawn, you’re not doing anything to proactively take care of weeds. If weeds do pop up, you’ll have to use a spot application of weed killer or pull the weeds to get rid of them.
If you have a lot of weeds and a hard time keeping them under control, a weed and feed might be just what you need to make your life easier and your yard better. A single application lasts for weeks, continuing to work throughout the summer.
Does Your Lawn Need Weed and Feed?
If your lawn isn’t exceptionally healthy and you need something that will help it grow stronger, faster, and greener and you have a problem with weeds, a weed and feed formula is beneficial if used in the right way.
Weed and feed is meant to be applied to your entire lawn. If there’s a part of your lawn that doesn’t need fertilizer or everything looks good except for one area with a lot of weeds, you might want to consider a product specific to the problem.
But, if a large part of your lawn needs both fertilizer and weed killer, using the best weed and feed suited to your lawn can be very beneficial.

When is the Best Time to Weed and Feed Lawn?
The best time to apply weed and feed to your lawn is at the end of spring when weeds begin to pop up. If you apply it too early, you won’t get the benefit of the extended-release fertilizer and may even hurt your grass if it’s not in its active growing phase yet.
Most of these products are only meant to be applied once in the spring. If you think you need to apply more, wait until the end of summer so you don’t over-fertilize. There should be at least two months between applications so the chemicals don’t build up in your yard.
Note that this only applies to established lawns. For new growth, you should only apply weed and feed after the lawn reaches about two inches high and has been mowed two or three times.
How to Apply Weed and Feed to My Lawn?
Every weed and feed has very specific application instructions on the packaging and you must follow them carefully. Here are some general guidelines for how to apply weed and feed:
1Mow and water your lawn one to two days before you’re planning to apply the weed and feed. Mowing the lawn helps ensure even distribution and granular products work best when they stick to the weeds.
2Choose a day when the temperature is higher than freezing but below 80 degrees F. Extreme temperatures affect your lawn’s tolerance so applying the product during this time could cause damage.
3Look at the weather forecast and try to time the application during a period when it is not expected to rain. Don’t apply after a heavy rain, either. You want the lawn moist but without puddles or standing water.
4Set the controls on your spreader. Rotary or drop spreaders are most common. The product that you choose will have very detailed application instructions on the bag that tell you exactly what settings to use.
5Apply the product using the spreader. Some packaging gives you suggestions as to how to make sure the area is covered evenly. Generally, you should walk back and forth across your lawn allowing for a little bit of overlap.
6If you get any product on the sidewalk or driveway, sweep it unto your yard with a broom. The idea is to do your best to prevent any granules from washing away and getting into storm drains.
7If you’re using a spray weed and feed, again, follow the instructions on the package. Attach the bottle to your garden hose and work in a precise pattern so you can be sure you covered the whole yard.
8Keep children and pets off of the lawn for a few days until the residual product has washed away. This usually means waiting until the first heavy rain or until you water your lawn thoroughly a few times.
Again, make sure you follow the instructions on the back of the product carefully. These weed and feed formulas have very specific instructions including how much product to use and what settings should be used on the spreader.
Because the timing of the application is so important to the effectiveness of the product, a lot of people may think that weed and feed doesn’t work or that it’s too hard on the lawn.
If you apply too early, your grass gets too much fertilizer before it needs it. Grass needs more nutrients when it’s actively growing fastest in the summer. That’s why these formulas are extended-release.
If you apply the product too late in the season and the grass is already brown and the weeds are already established, weed and feed is likely to be ineffective.
As we said, if you applied the product in the spring and feel it’s been ineffective, you have to wait at least two months before you can reapply. To be on the safe side, you should wait a little longer, possibly until the end of the summer.
When to Water After Applying Weed and Feed?
One of the most important things to remember is you don’t want to water your lawn right away after applying weed and feed. Your lawn should have been moist when you applied the product so this shouldn’t be a problem.
Watering your lawn too soon after applying a weed and feed product will wash the product away, causing it to be ineffective.
Check the instructions on the product that you choose to be sure. Each product is different but, generally, you’ll have to wait at least 24 hours before watering your lawn. Some products recommend waiting as long as four days or so.
This is why it is so important to check the weather forecast before you apply your weed and feed. If heavy rain comes the day after application, it will wash away the product. It’s best to find a stretch of about five dry days or so to make sure you can apply the product effectively.
