Obviously you want something toxic to weeds. Well, more accurately, it’ll kill your cells, but really what are you if not a collection of your cells? I’m saying that there can be a time and a place for responsible herbicide use. I’m not saying it’s time to break out the Round-Up. I approach this topic with hesitation, because some of you stopped reading at the second sentence and are right now composing long ranty hate-emails describing how I am worse than BP and Monsanto put together to even suggest folks use herbicides.īut hold up a moment. This may be a situation for an herbicidal spray.

Horned oxalis, like most of the oxalis species, is able to tolerate most of the commonly used selective herbicides, and results with common sprays like MCPA750 and 2,4-D 720 Amine can be very disappointing, as can treatment with sprays containing clopyralid. It also appears in lawns, ornamental and sporting turf, though the smaller, native creeping oxalis is more common in those locations in NZ. It particularly favours gardens as well as closely grazed pastures. Horned oxalis is found across most of the world, and is common throughout New Zealand.
There have been reports from Australia of sheep being poisoned by horned oxalis, though nothing similar reported in New Zealand. fishtail oxalis, Bermuda buttercup, pink shamrock and others) The plant also spreads via seeds, but does not have the underground bulbs found on some other similar species (e.g. This allows the plant to form quite dense patches in pastures, turf and lawns. Horned oxalis spreads readily because of its stolon's, which is a stem that creeps along the ground and produces new roots at the stem nodes.
The creeping oxalis flowers are also smaller, and nearly always appear only singly rather than in clusters. the flowers are normally only up to 10mm across). The similar native creeping oxalis mentioned above also has yellow flowers and trifoliate leaves but it’s smaller in all respects (e.g. The leaves are generally up to 20mm across. This forms the classic ‘three-leafed-clover’ shape. Leaves are trifoliate, which means they are made up of three leaflets each of which is notched on the outer end. It flowers from December to January in most locations. The flowers are yellow, and grow up to about 1cm in diameter, sometimes singly, but more often in clusters of from two up to five flowers per stalk. Horned oxalis is a perennial weed species that grows low to the ground. The other smaller, common relative that looks similar is creeping oxalis (Oxalis exilis), which is a native oxalis. This species of oxalis is the larger one and is the one of more concern.
