Rosemary is an aromatic herb widely used in our kitchen. But it can also be very useful in the vegetable garden, especially if grown in the same plot of land with some vegetables. In fact, it removes two parasites that produce harmful larvae for some vegetables. All according to the dictates of the association, which we have already discussed on our pages. This ancient agricultural practice consists in exploiting the advantages that two or more crops give each other when grown close together. Some plants are compatible with each other, others must instead be distant because they risk damaging each other. Sometimes, intercropping simply consists of a peaceful coexistence between two or more plants, which do not steal nutrients or space. In this case, the association between rosemary and the plants that we will name is useful for their survival.
Planting rosemary next to these vegetables is the winning move to say goodbye to some dangerous pests
Cabbage is an insect particularly attracted to cabbage and plants belonging to the cruciferous family, which also includes cabbage and broccoli. It is a moth that lays larvae that are harmful to plants. Its larva can be recognized by the bright yellow color of its skin, with black and irregular spots. The thin yellow hairs on its back also stand out. They devour cabbage leaves, which they are fond of, and in the long run can cause their death. The adult butterfly has white wings and a wingspan that reaches sixty millimeters. Rosemary can be grown together with all cabbages and its presence bothers the cabbage, which will not lay its eggs on the plants.
But the help provided by rosemary does not end there. Another good association is that between this aromatic herb and carrots. Rosemary can drive away the flies that tend to besiege these vegetables. The carrot fly is distinguished by its bright black body, the body of about four to five millimeters and with green reflections. Again, the problems are caused by its larvae. Once their eggs have hatched, they penetrate the soil where the carrot is grown, enter the plant’s taproot and feed on it by digging tunnels. Their action damages carrots, changing their smell and taste for the worse and, in the worst case, causes them to rot. Planting rosemary near these vegetables is the winning move to say goodbye to some dangerous pests, not to be underestimated.
But if the larvae of these parasites already infest the plant, it is too late
If the plants are already under attack, suddenly planting a rosemary won’t do much good. In that case, it will be necessary to intervene in the appropriate way to avoid permanent damage to crops.
