Weeds are a problem in areas where ornamental plants are grown. Recognition of these weeds is important in determining the appropriate control method with them. The area where ornamental plants will be planted must first be a place without foreign weeds. If an area with weeds is to be selected, planting should be performed after the tillage and herbicide application. Since ornamental plants contain many plant species with grass and broadleaf, maintenance operations such as fertilization and irrigation should be performed more precisely in order to prevent the contamination of weeds in these areas. Otherwise, difficulties will be experienced in the fight after contamination due to the fact that weeds can have both grass and broadleaf.
Weeds can be kept under pressure by using mulching and cover crops in ornamental plants. Some weeds can control with picking or hoeing. If manual collection or hoeing is to be performed, it will be easier to perform these operations when the soil reaches the proper consistency as the soil will soften after rain or irrigation. One-year weeds are easier to control with hoeing. Managing them before setting seeds significantly reduces their density. However, herbicides can also be preferred in terms of practicality and cheapness. However, herbicides to be used in ornamental plant production areas should be carefully selected. Label information should be read carefully and used according to the information here. It can be said that especially annual ornamental plants are more sensitive to herbicides. In suitable ornamental plants, the appropriate herbicide should be applied at the appropriate dose and at the appropriate time. Soil herbicides should be preferred to suppress annual weeds. For the control of perennial weeds, post-emergence herbicides should be applied when these weeds are 20-25 cm and actively grow. Perennial weeds can be suppressed with 3 years of regular herbicide use.
Weeds are still an important problem in ornamental plants, and there is a need to develop alternative soil disinfection with steam and cover crops, also modern methods such as robotics and drone technologies.
