This page looks at options for gardeners when oxalis are becoming a problem. The RHS believes that avoiding pests, diseases and weeds by good practice in cultivation methods, cultivar selection, garden hygiene and encouraging or introducing natural enemies, should be the first line of control. If chemical controls are used, they should be used only in a minimal and highly targeted manner. First, consider whether control can be achieved using non-chemical means such as digging out or suppressing with mulch.
Where these methods are not feasible, chemical controls may be necessary. Choose a weedkiller that is most appropriate for that purpose by reading the label carefully before buying or using. Contact weedkillers or glyphosate-based products, which have low persistence in the soil, may suffice. Take particular care when using residual weedkillers, which persist in the soil for several weeks or months, as they can move deeper or sideways in the soil, leading to possible damage of underlying roots.
Unfortunately, Oxalis corniculata which is problematic in lawns shows strong resistance to the full range of selective lawn weedkillers. Some control can be gained by treating oxalis with the non-selective weedkiller glyphosate e. The most effective period for application is in spring when the oxalis is growing actively and vigorously. Be prepared for some re-growth later in the season or the following spring, which will need a repeat application of weedkiller.
Protect grass and garden plants from accidental spray drift, or apply glyphosate specifically to the leaves of the oxalis. Used with care, glyphosate is safe to use around the base of non-suckering woody plants, as long as the bark is woody, brown and mature.
