For a bermuda lawn the weed and feed to buy is Scotts Turf Builder Weed & Feed3, applied after the lawn has fully greened up— which in most of the South means late April or May, not March. If the weeds are already up and winning when bermuda wakes, Scotts Turf Builder Triple Action1 adds a pre-emergent to the same job. And if you are reading this in late winter, the right product is not a weed and feed at all: it is Scotts Turf Builder Halts, a crabgrass pre-emergent, because feeding a dormant bermuda lawn feeds the weeds and not the grass.
That timing point is the whole reason this page exists separately from our main weed and feed roundup. Bermuda, zoysia, St. Augustine and centipede are warm-seasongrasses: they go dormant and brown in winter, green up when soil temperatures climb into the 60s, and do their growing through the heat of summer. Cool-season lawns — fescue, bluegrass, rye — do the opposite. Nearly every weed-and-feed bag on the shelf prints a calendar written for the cool-season lawn, and following it on bermuda means applying nitrogen to a brown lawn that cannot use it.
One more thing before the picks, and it is the most important sentence on this page: read the grass-type list on the label before you buy. Lawn herbicides are selective, and what they are selective against varies — a product perfectly safe on bermuda can damage St. Augustine, and the reverse is true too. The label is a legal document and the EPA requires you to follow it. If your lawn is St. Augustine or centipede rather than bermuda, the last pick on this list is the one for you and the first few are not. Prices below are live from the price layer with an “as of” date.
The warm-season calendar, which is not the one on the bag
| When | Bermuda is | Apply | Not |
|---|
| Late winter, soil near 55°F | Dormant or waking | Crabgrass pre-emergent, no fertilizer | Weed and feed — the nitrogen is wasted |
| Green-up, roughly April | Greening unevenly | Nothing, or spot-spray broadleaf weeds | A full feed before it is fully green |
| After full green-up, late April to May | Growing | Weed and feed, watered in | Pre-emergent only — too late for crabgrass |
| Summer | Growing hard | Feed on a schedule; spot-treat weeds | Blanket herbicide in extreme heat |
| Early fall | Slowing | A last feed, fall pre-emergent for winter weeds | Heavy nitrogen late — it invites disease |
| Winter | Dormant, brown | Nothing | Any feed at all |
The general-purpose version of this calendar, with the nitrogen arithmetic behind it, is in the lawn fertilizer schedule, and the bermuda-specific feeding detail is in best lawn fertilizer for bermuda.
Why March is the mistake everyone makes
March is when the garden centers stack weed and feed by the door, because March is right for most of the country. In Texas, Oklahoma, Georgia, Alabama and the rest of the bermuda belt, March is when the lawn is still brown or patchily waking. Nitrogen applied then does three unhelpful things: it feeds the cool-season weeds that are actively growing, it can push a tender early flush that a late frost burns, and most of it is gone before the grass is ready to use it.
The fix is to split the job. In late winter, when soil temperatures approach 55°F, put down a pre-emergent with no fertilizer— that is the window where you stop crabgrass, and it closes once crabgrass germinates. Then wait. Once the lawn is uniformly green and you have mowed it two or three times, apply the weed and feed. You have now hit both targets instead of missing both.
How weed and feed actually works, and the two rules that follow
A granular weed and feed is fertilizer prills plus a herbicide-coated carrier. The herbicide works on contact with leaf tissue, which means two things follow directly and neither is optional.
Apply to a damp lawn, and do not water it in immediately. The granules have to stick to wet weed leaves long enough to be absorbed. Morning dew is ideal. If you irrigate straight afterward, you wash the herbicide off the leaves and into the soil, where it does nothing for your weeds.
Then water, 24 to 48 hours later, to move the fertilizer in.That is the opposite requirement for the other half of the product, which is exactly why doing the two jobs separately — a straight feed, plus a liquid herbicide sprayed on the weeds — gives a better result. That is what the Andersons 16-4-8 plus a selective spray combination on this list is for, and if you want the best outcome rather than the fewest trips, that is the route.
Bermuda in Texas, and southern lawns generally
Two complications specific to the region. First, a lot of “bermuda” lawns in Texas and the Gulf states are actually St. Augustine, which looks coarser and spreads by thick runners. Getting this wrong matters more than any product choice on this page, because the herbicides that suit each are different. Second, the summer here is long and hot enough that blanket herbicide in extreme heat will stress the lawn itself. Most labels carry a temperature ceiling for exactly this reason. In July and August, spot-treat rather than broadcast.

The product never to put on bermuda
Atrazine. The Southern Ag bottle on this list is labeled for St. Augustine and centipede, and that naming is not marketing — it is the label telling you which grasses it is selective for. It is an excellent product on the lawns it names and it is not the product for a bermuda lawn. We list it here because half the people searching for a southern weed and feed have one of those two grasses and need to be sent to the right bottle, and because “southern lawn” advice that ignores the difference is how lawns get damaged.
The same logic in reverse: check any product you buy against your grass type, every time, even if you have used the brand before. Formulations change. The EPA's position is simple — the label is the law.
If the lawn is overseeded with ryegrass
A lot of bermuda lawns in the South are overseeded with annual ryegrass for winter color. If yours is, do not apply a pre-emergent in fall — it will stop the ryegrass germinating along with everything else — and be careful with spring herbicides while the rye is still present. The cleanest approach on an overseeded lawn is to let the rye die back in the heat, then start the bermuda program after green-up.
Spreader setting, and the one number that matters
Every bag prints a coverage area and a setting for the common spreaders, and the way to get this right is to work from the area rather than the bag. Measure the lawn, set the spreader to the label figure, and apply half the rate in one direction and half across it — two light passes at right angles give a far more even result than one heavy pass, and streaky weed and feed is visible for weeks as green and yellow stripes. The spreaders themselves are ranked in best broadcast spreader, and the edge-blocking feature on a good one is what keeps herbicide out of the flowerbeds.
