The most common "sins" of gardeners are:failure to comply with the recommended doseandconcentration of the preparation(too high dose and too high concentration), spraying in unfavorable weather conditions(too much sunlight, high or low temperature, precipitation, etc.) and carrying out the treatmentwith faulty or inadequate equipment(e.g. windscreen sprayer or watering with a watering can).
How to protect plants from weeds
Before each treatment, carefully read the information on the label - instructions for useplant protection productand follow them accordingly. The treatment should be performed with an adapted sprayer (preferably a shoulder or knapsack sprayer with an attached sprayer - nozzle, slot tip) on a day when it is not raining, not in full sun, during windless weather.
Diseases that may attack in July
- Black spot of roses - the symptoms of black spot of rose appear on roses: the leaves begin to turn yellow and become covered with dark spots. Infected leaves should be plucked and the bush can be sprayed with the recommended fungicides.
- Powdery mildew - symptoms of powdery mildew in the form of a white, powdery coating on the leaves can be observed on various plants.
- Infections of plants - plants with symptoms of infection should be removed from the beds, as they are a significant source of infection for other plants of the same species.
When couch grass weeds the lawn over a larger area, it is worth considering destroying couch grass with other plant species and re-planting the lawn in the same place. As a result, couch grass will not be a problem in the next year. For this purpose, you can use the so-callednon-selective herbicides(total), which destroy monocotyledonous and dicotyledonous plants.
Sowing a "new" lawn should be done3-4 weeksafter treatment. This time is needed for the remnants of the preparation to decompose and thus not to be toxic to emerging plants.Non-selective herbicides are also very useful for controlling plants on terraces, paths, cobblestones and cemeteries.
