Confusion on Timing of Winter Annual Lawn Weed Control

If you’ve had a history of winter annual weeds in your lawn, the best option is to apply a preemergence herbicide during October. But, winter annual lawn weeds don’t exist yet. They are in the form of seeds now.

Understanding this timing is critical.

During late February to mid-April, homeowners bring in bags of winter annual weeds from their lawns wanting advice on how to control these weeds. They usually seem disappointed and confused when I tell them that it’s too late to bother with controlling winter annual weeds during late winter to early spring. They usually follow with a statement and a question such as, “Well, my lawn is full of these weeds now. What can I do?” I suggest to just mow them and explain that these weeds will completely die as a result of the warmer temperatures of late spring and early summer.

At this point, looking frustrated, the homeowner may ask, “Is there something I can spray on my lawn to kill these weeds now?” To which I reply, “Yes, but it’s mostly a waste of time and money this late.” I then try to explain the winter annual weed lifecycle. The weed seed remain dormant during the hot summer months and begin to germinate in fall. The new seedlings continue to grow through winter, mature, produce flowers and countless seed. By late winter/early spring (when the homeowner is asking about control), these winter weeds are at the end of their lives. They are almost done with producing seed and will begin to die with the coming warmer temperatures of mid spring. Control should have been attempted just ahead of the beginning of their lives, in October; not at the end of their lives during late February to mid-April.

Perhaps part of the problem with understanding the importance of timing when applying a preemergence herbicide is due to the fact that the herbicide is applied before there are any weeds. The preemergence herbicide needs to be applied during October when nighttime temperatures drop to 55° to 60°F for several consecutive nights. This will be just before the winter annual weeds emerge. Done correctly, the application of a preemergence herbicide forms a chemical barrier along the soil surface preventing the winter annual weeds from emerging. Hence the name preemergence.

A second application may be required six to nine weeks after the initial application to achieve season-long control, based on the product’s label directions.

Follow label directions and precautions when using any pesticide, including herbicides.

Common winter annual weeds include chickweed, henbit, Carolina geranium, annual bluegrass, hop clover and lawn burweed.

Do you have any sessions scheduled for problem lawns in the Gainesville area. My lawn has root rot and nematodes and any Bermuda grass just peels up. The St. Augustine grass seems to maintain their roots. Our lawn Service suggested putting Command soil on it which is scheduled soon. Any other suggestions. Never had really bad problems until we hired a lawn service 1 1/2 years ago. Help

The myth of cheating or beating the slot machines is just that it is an untruth. Although it is possible to win at slot machines, you should always remember that statistics and the odds are not favoring you. This is the fact of playing slot machines. With so many positive things about the slots-one of them being jackpots, payouts, winners, and happy gamblers-there is no reason not to test your luck by playing the slots online.Don't be fooled by the con men and gimmicks claiming that you could win thousands of dollars in mere moments by playing the slot machines. There's no specific policy or set of rules that will ensure that you can win if you buy the book or set of rules. Winning and luck are not available for sale.When you decide that you want to play online slots, you should know that there are always fraudsters that want to prey on you and your desire for excitement and thrills. There are always additional advantages to winning money. It is essential to understand that you are in the hands of the random generator of the machine when you play. Online slots or traditional slot machines that are based on land it is the machine that is the sole factor determining if you are winning or losing on the slots. You can lose your money more quickly by investing in the system or paying an expert for help. It is better to be playing random slots and crossing your fingers.

My grass keeps dying and seeds will not even sprout. Several theories have been proffered by landscapers, including fungus, web worms, excessive watering, too much shade, etc. Problems stated about 10 yesrs ago. Before that we had a great lawn, nostly Persly Seville. Can you tell me what king of test or tests we need to define the problem? You can call me at 850-897-6545, or reply by email.

Unfortunately, the seminar was cancelled due to COVID-19. I'm looking forward to when we can offer this again, hopefully in 2021.

When targeting control of winter (cool-season) annual weeds, the preemergence herbicide should be applied when nighttime temperatures drop to 55° to 60°F for several consecutive nights. This will be just before the winter annual weeds emerge. In North Florida, this normally happens during October. When targeting control of summer (warm-season) annual weeds, the preemergence should be applied when day temperatures reach 65°to 70°F for 4 to 5 consecutive days. This will be just before the summer annual weeds emerge. In North Florida, this normally happens during February. Also, you may want to check with the Purdue Extension Office in your County on the correct timing.


October 26, 2020

The key is to make sure that you are using a herbicide, whether it is a pre or post emergent herbicide, that is labeled for use for the lawn grass and/or pasture grass that you have. For example, some herbicides are labeled for use on bermudagrass and bahiagrass but are not labeled for use on centipedegrass or St. Augustinegrass and visa versa. Using a herbicide that is not labeled for the particular lawn or pasture grass that you have could injure the grass. Always follow the label directions and precautions for any pesticide that you use, including herbicides.

Mirtha Guerra Aguirre
October 26, 2020

Does the herbicide that needs to control the weeds also kill the grass? I would like to control weeds, on yard and in pasture, but I do not want to kill the grass and have to reseed next year. I have Argentinian Bahia Grass. Thanks

I don't think there is a published threshold for beans. For soybeans, we use a 15-inch sweep net. One nymph per sweep would be needed to trigger a pesticide application. Pesticides that are effective on kudzu bugs can be very harsh on beneficial insects. This can cause a flush of bad insects following the pesticide application. I would check for any kudzu bugs on the ground that are infected by the fungus. Often the fungus will keep them below thresholds. If you are dead set on using a pesticide, a pyrethrin is effective on them but also will kill beneficial insects.

June 29, 2020

I have already contacted my local Bay co. extension office about this bug attacking my Blue Lake bean plants. There was no recommendation for pesticide but you mentioned in this article spraying the soybean field. Do you have a recommendation as a pesticide that would work on these type of bugs? I know sevin spray doesn't work.

Thanks for encouraging people to accept some damage on their citrus. I agree with you - it is worth it to have giant swallowtails in our communities. Another larval food plant that folks might consider planting is the native hoptree (Ptelea trifoliate). I have never known giant swallowtails to eat fennel. Both giant swallowtails and black swallowtails eat rue.

What a great way to put our priorities in perspective! We all need to remember this.

March 17, 2020

Thank you, Larry. I agree that our landscapes should be a place to learn, enjoy and make memories. I love sharing my gardens with my seven grandchildren, watching them as they discover a new clutch of Bluebird eggs or identify a hummingbird or Monarch butterfly. They certainly don’t notice the weeds! Also, over the years, I have decided that native plants are the way to go and old fashioned shrub roses are much less time consuming than the hybrids and are more fragrant.

March 17, 2020

Our expectations today arise from what we see in picture perfect landscapes in magazines and social media. We live in a harsh climate in NW Florida and much of what we plant cannot survive here without being coddled. All of the plants you mentioned your neighbor having are tried and true for our area. We would have less angst if we put the majority of our landscape in those types of plants.

Typically the weight of the tree or branch breaks a line, shutting off all power. It can be a fire concern, but that is not the usual concern. The utility guys concentrate on main roads and areas with schools, hospitals, nursing homes, etc. Many times these places have people dependent on machines for health issues.

I never thought about the fact that they have to remove so much vegetation, so that even when the windstorm comes, the tree isn't touching the line. What is the greatest concern about trees being close to the lines? The chance of causing fire, or the weight of the tree on the line?

Soil solarization, done correctly, can be helpful in controlling nematodes in the vegetable garden. Here are the basics taken from the UF/IFAS Extension publication Nematode Management in the Vegetable Garden ( Soil solarization is a process of using heat from the sun to kill nematodes and other pests. The soil should be worked with a hoe or rototiller to break up clods. Remove all sticks, roots, and clumps. The soil should be moist but not wet. Cover the soil with a clear plastic tarp and bury the edges of the plastic (Figure 14). Leave the plastic on the soil for at least 4 to 6 weeks. Do not remove the plastic until you are ready to plant.Sunlight goes through the clear plastic and heats the soil underneath. The plastic then holds in the heat so that it penetrates and warms the soil. Long-term exposure to high temperature kills nematodes, as well as many weeds, fungi, and insect pests. The disinfested zone is usually 6 to 8 inches deep. Do not till or mix the soil after solarization. That may reinfest the soil you just solarized with nematodes from below the treated zone. Because it depends on sunlight and heat, solarization works best during the summer months. It does not work well in areas that get shade. Only solarize planting beds that get full sun.

How do you get rid of nematodes? Use black plastic for how long to kill them in hot weather.

Hi, sorry. Yes, I tried to fit too much into my short allotted time. Cool season forage options include: • Legumes – arrowleaf clover, crimson clover, ball clover, red clover, white clover, vetch and winter peas to name a few. • Grasses – ryegrass, oats, wheat, rye, and triticale (a man made cross of wheat and rye). • Brassicas like kale, turnips and tillage radish • Forage Chicory Some good warm-season food plot plants include: Perennial Peanut Forage Soybeans Alyceclover Jointvetch Iron clay peas Lablab And Brown Top Millet If you would like more specifics on planting dates, depths, rates, etc, you can email me at and I will send you publications that can further help you establish successful food plots. Thank you!

the week of March 11th, your 5:15AM radio spot talked about summer time food plots for deer. You apparently ran out of allotted time while trying to give examples of various seeds to plant for deer food plots, that you spoke so fast and hurried that it was unintelligible as to the list of seeds to plant. Can you provide the list to me by e-mail? thanks, //david//

It is a great practice to start your own little garden, when less agricultural land is available for growing food. Genetically modified crops are available, we can grow our own food using Aquaponic/hydroponics. The first method did not require any food for plants as fish wastes will be used as a plant nutrient.

So glad UF is taking the lead in trying to find ways to reduce lion fish population. If there is no form of control then the fishing industry is doomed. I would support the federal government subsedizing fisherman to harvest lion fish to make it profitable to them.. Then we can make a dent in this distructive fish.

Lionfish are attracted to structure and the lattice acts as structure. Earlier prototypes were bulkier and weren’t able to be stacked (more room on the boat) like the current design is. The lattice is 2D so can be easily closed within the trap. This was mostly figured out through iterative design ideas and trials by Steve Gittings.

It depends on the species. Red Oak, sweetgum, ash and most other hardwoods are deciduous as normal. Water oak and laural oak slowly lose their leaves all winter long, are pretty bare in February until the spring green up. Magnolia and Live Oak hold on to their leaves throughout the winter and shed in spring before new growth occurs. Bald Cyprus is 100% deciduous and Pecan are late to drop their leaves and the last to break dormancy. Many other trees lie in the middle of the spectrum. Fall color here on trees is seasonal and varies with the fall temperature and rain level except on Sweetgum, and a few other species like the invasive non-native tallow tree which are fairly consistent .

How do deciduous hardwood temperate trees change in panhandle Florida? I know the leaf exchange is later & into much of the winter? How long are the trees green 7-8 months & how long with fall colors? when do they drop leaves & how long before new leaves bud & when? It is like the trees are just "semi-deciduous" in the panhandle ?

August 2, 2015

Are you saying Round-up is not harmful and Glycopyrrolates do not persist in the environment? I believe recent studies de-bunk your response to Myth #2. If you follow the studies that are coming out of India, you will see that the "common" farmer there, in an attempt to eradicate weeds that are resistant to Round-up, are using more and more herbicides. This eradicated any profit the farmer might have had, instead of the resistant weeds. I believe the research into using synergistic combinations of pesticides and/or herbicides have proven to be much more successful in reducing the amount of toxic chemicals used, as shown by our extension service reports in Alabama. Good old fashion genetic manipulation, though slower, is a more safe - and sane - approach to altering and improving our food crop plants. Personally, I have "tested" my pets on GMO foods - giving them a choice of naturally, locally grown foods, side by side, with GMO foods... every food choice was the naturally grown food. For me and my family - and my pets - we are willing to pay the extra cost and will continue to buy non-GMO and organically grown foods.

We are wondering where our hummingbirds have gone. We usually have 4 or 5 that visit our yard in season. We had three of them in April but they left early in May and have not returned. Do you thing those may have been scouts who have gone to bring the others? We know at least one of them has been here for at least 3 years..we recognize him because he has no feet. All of us along our little strip of the bay miss them and are hoping for their return.

Huh, I didn't realize that we should be so particular about fertilizing, but then, I haven't had to care for a lawn since I lived at home; and then, my dad did all the planning. Now I am renting a house with a small front lawn which is in desperate need of love. I can probably start fertilizing, now, since it is the end of May and we have been having some good, constant, light rain. How regularly should you fertilize your lawn during the summer?

Good suggestions. I enjoy gardening for pollinators. Can you tell me the name of the conradina t hat is planted at your Extension office. I've noticed it's an early bloomer for those early butterflies and bees.

Because our garden is primarily for raising butterflies, it contains host and nectar plants for many caterpillars. In our situation, wasps are not beneficial and we selectively reduce their populations to give the caterpillars a better chance of survival.

Thank you for this article. I knew enough not to prune most of my dead-looking plants. I usually wait until I can see pecan tree leaves in the spring before giving up and pronouncing something dead.). But I was thinking about pruning back my pineapple sage, which is the worst-looking of the lot and prominently located. Now that I understand about the food-storage thing, I was wondering if it would be okay to do the cambium layer thing one internodal bit of stem at a time and prune off what is actually dead, working my way down the branches until I come to green in the cambium layer?

Unfortunately, there really is not a good chemical option for azalea/camellia leaf gall. Thankfully, it really does not cause long-term problems for the plants. It just looks bad. But eventually the infected leaves fall off and new ones come on... so the plant grows out of it.

If you live in Florida they will return fine with no protection. Do leave the old stalks all winter and only remove them in the spring after the last frost. Additional mulch is helpful if you live in the far north end of a Panhandle county. You will see growth reappear sooner in the spring.

Good article Sheila especially about the soil/water relationship with tree physiology. I didn't realize that the lack of oxygen worked that quickly. There is an alternative to protecting trees from infestation when nearby trees are infested. Basal soil injection or drench with Dinotefuran or Imidacloprid. Dinotefuran gets in the tree much more quickly than Imidacloprid. The stuff is not cheap though. Spray the bark to give a measure of protection for a week or two to give the Dinotefuran time to get into the tree. Season long availability of insecticide in the tree.

I frequently see them working plants for insects. thanks Frank Sedmera

It's funny that you should write about wasps. A few days ago I was stung by a wasp as I was cutting old leaves off my banana plants. Wow! It felt like a hypodermic needle, very painful. There were at least 3 wasps hovering in the dense growth, and didn't notice them until it was too late. I do respect all those stinging creatures because I know they are beneficial.

Those lichens are not harming the tree but "get in" due to sunlight. Your theory about winter infestation sounds right. Copper fungicidal soaps are available at your garden center, and may act as a control for lichens and have to be used carefully on plants that are already leafed out. Dormant application would be better. Here are two extension publications from Oregon State and Texas A&M that address the question from an interesting angle. Hope this helps, Matt

April 28, 2014

Yes, it looks exactly like the lichens. I think the Crape Myrtle losing all of it's leaves during the winter may have given it a "foothold", but my Crape Myrtles are now growing in leaves like crazy and hopefully, will resume normal and do away with the lichens. I cannot help but to wonder if this is why people began drastically pruning the Crape Myrtles in the winter, because they wouldn't have had any place for the lichens to land on, had I pruned them the way a lot of people do. The tree trunks have this amazing thing that they do where they shed their bark occasionally, so it would have been unaffected. I've even found large pieces of the trunk's bark on the ground with the lichens on it, which I immediately threw in the trash. Do you have any other recommendations? They are otherwise very beautiful and mature trees.

Matthew Orwat
April 28, 2014

Sounds like you have the type of lichen that looks like an air plant. Look at the picture of the lichens. Is this what you have?

April 22, 2014

I have a serious infestation of I think a specific type of air plant. It is NOT Spanish Moss, but is little gray short hairy things that gradually take over a bush or tree, then finally kills it. In the last few months, they have moved to my mature (and GORGEOUS) Crepe Myrtles, so now the panic button has officially been pressed in me. I had a "lawn expert" come and he said it is an air plant, and to brush it off, but there isn't much you can do about it since they travel in the air. I do not trim back my Crepe Myrtles in the winter, so they have never been trimmed and they are huge and gorgeous and I just hate to lose them. I read up on the matter and Copper seems to be one possible solution, but then I read over and over that air plants do not kill trees. I watched it gradually kill a bush, going from just a very tiny bit on the bush, to completely overtaking it and killing it, so I don't know if I can bear to watch it kill these Southern beauties. Please help!!! Warmest Regards, Debbie
