![]() If you donate manure to gardeners the herbicide in your manure could kill garden plots for several years before the residue breaks down.If you suspect a person has ingested parts of a poisonous plant, immediately contact the National Poisons and Hazardous Chemical Information Centre Urgent Phoneline on 0800 POISON (0800 764 766) 24 hours a day, 7 days a week.įor non-urgent information, Ph between 9am and 5pm week days only. Some broadleaf specific can remain on grass, be eaten by livestock, and pass still active into manure. It may be better to just overstress the buttercup when it flowers.īe careful of commercial herbicides. So you may want to mow right behind a grazing if the buttercup is dominating.I know this is tough if you try to keep a sward height of 8 inches. From a plant's point of view mowing=top eaten off. This paddock rotation process could take a couple of years to make headway.ĭon't forget that a mowing counts as a grazing cycle. Make sure you have a seed bank of warm season annual, and cool season perennials in the soil. You dont want the herd to be forced to eat buttercup out of hunger, they generally avoid it unless there is nothing else.Įach paddock should have 21 days to recover, or 8 weeks in the case of sheep due to parasites. The actual grass should not be eaten lower than 8 inches, then you move them. Small paddocks are made where the animals are tightly bunched, and they only graze one area for a day to several days. We practice management intensive grazing. You dont want those flowers to go to seed. ![]() On our farm we manage it by intensively mowing the buttercup like one would a lawn. for horses)īuttercup thrives following over grazing, as the herd avoids it and eats the good forage first. Would be happy to hear from people on this (i.e. But I haven’t been able to find good studies on this. Or course stuff I have read in preparing this has stated that the commercial chemicals for control of broadleaves in pastures are fine. * I understand why you would not like to use commercial products (I hesitate to say chemicals as that is what vinegar is). With a pump spray it would be an addition to manual control. These work well with some science to back them up. Ĭould you give the pasture a break? Or section of parts to give the grass a chance.įinally, people do use vinegar and/or clove oild as a spray to kill weeds. Is your pasture at high productivity? Overgrazed pastures are much more likely to show heavy infestation in the spring. Regular mowing helps prevent weeds from establishing, spreading, and competing with desirable grasses and legumes.” Also, mow along fences and borders to help prevent the introduction of new weed seeds. However, mowing three or four times per year over several years can greatly reduce and occasionally eliminate certain weeds. “Mow at a height above the grass seedlings when weeds are 8 to 10 inches in height to reduce shading by weeds.” A single mowing will not satisfactorily control most weeds. Set the mower just above the height of the grass. By cutting the weeds with a mower you prevent them flowering and cause them to expend energy growing new vegetative parts (which you mow again). ![]() Here is a video from the RHS on weed removal.Īnother useful approach that can occur alongside planting new grass is mowing. Especially if you focus on this now, before the buttercups set seed. This is hard but as you keep at it you will reduce the amount of weeds. Since you dont wish to use chemicals* So, you best solution is manually removing the weeds. Note that you want to reduce seeds entering your pasture and this can happen with animals and vehicles. Here is a great (GB) resource on planting grass If you also grow beneficial plants that serve as forage this can help. Buttercups propagate by seeds and this occurs late in summer so ensuring healthy pastures before then will help prevent the weed from spreading. It is difficult for them to establish in taller vegetation. See page 7 from this great Teagasc report (Irish Ag Board. Also, horses will use sections of the field as latrines and this is where buttercups grow in abundance. They also grow in areas of excessive damage following heavy rain, which has been common this spring. The best control for all weeds in forage is to have a thick stand of grass. But if the field contains little grass then they will consume the weeds. The general consensus is that horses will avoid buttercups and other weeds. If you make hay then the toxicity will not carry over as it is lost when dried. The toxic component is in the fresh leaves and flowers. ![]() ![]() It also can cause dermatitis is people so avoid picking without gloves. They contain protoanemonin which is a irritant of the GI tract and also causes oral irritation. You are right to be concerned as buttercups are poisonous. They are common in overgrazed horse pastures. The buttercup species (Ranunculus species) includes several annual and perennial plants. ![]()
