my lawn of dicondra is full of weeds can I use a grass rooter without damaging the lawn? or what do you recommend?
the dichondra is a ground cover plant with horizontal development, very low, with roundish leaves, very decorative, which is used to prepare low maintenance turf, as the adult plants continue to widen, maintaining their maximum height below 10 -15 cm. Unfortunately it has a defect, which is often taken lightly: the growth in width of the plants is not as rapid as for the grasses that are usually used for the lawn, and the seeds cost a lot. The result often causes, for some years, "spotted" meadows, with some colonies of more or less large dichondra, which vegetate among the weeds, which often find free soil for their seeds. Generally the dichondra proves to be more resistant over time, compared to other plants, and therefore over the years the turf thickens; but to have a compact and green lawn effect it is usually obvious in two ways; in one case the dichondra is sown mixed with common lawn grass, such as poa or loietto: these two essences temporarily fill the holes present in the lawn of dichondra alone; with the following sowing, of only dichondra, slowly the graminaceous ones are supplanted, up to obtain, in the arc of two or three years, a beautiful compact lawn of dichondra. Or you prepare the soil first, treating it pre-sowing, even two or three times, with a foliar herbicide, which will kill almost all the weeds, so as to have very few in the future turf. If neither of these two choices have been made, you will surely find yourself with a dichondra turf, with patches of other random herbs, often unpleasant, or that fear the cold and leave real holes during the cold season . Certainly it helps to repeat some sowing in the spring, in order to help the dichondra to thicken; it also helps to mow the lawn, very very low, leaving only a few millimeters of grass: in this way the dichondra tends not to suffer at all, while the weeds dry up. There are also selective herbicides for dichondra lawns; obviously we cannot use the common selective herbicides of grassy turfgrasses: the selective herbicides for the common lawn are usually suitable for plants with rounded leaves, and therefore they are not absorbed by the linear leaves of the common lawn grass; but the dichondra has a roundish leaf, and is often devastated by herbicides. Specific selective herbicides for dichondra turf should therefore be used; these herbicides are generally suitable for drying a certain family of plants: for example, there are valid herbicides against grasses, or against legumes. It helps a lot in choosing the herbicide, to bring to the nursery where you want to buy, some sample of the weed (or weed) that you want to weed, so that you can choose the most suitable herbicide for the purpose.
