In these days where environmental problems increase, environment-friendly landscape project are designed to protect ecological balance. Accordingly, landscape designs which do not need chemical usage, water-saving minimizes the costs of its maintenance. The need of diverge to xeriscaping designs which also holds eco-friendly alternatives rather than landscapes with high water consumption is quite obvious. The stone garden landscape designs not only save water but also control weeds with the geotextile materials laid underneath the stones. Plant usage in stone garden landscape designs is also considered as an option. In such cases, it is important to know whether the geotextile materials that are laid underneath the stones have a limiting impact on the development of plants or not from this point of view, geotextile material's (polypropylene) impacts on the development of plant (Tagetes erecta L.) is researched as to set an example about stone garden landscape designs in the experiment fields at Ege University Bayindir Vocational Training School Campus (four-month summer period of year 2019). The research was conducted according to the randomized block experimental design carried out in three replications. In the research conducted as open field plots experiment. The results obtained revealed increase in weed control and plant development in stone garden landscape designs supported by the ornamental plants. As a result of this research, it is recommended to use polypropylene cover under stone material for weed control in stone garden landscape designs as it did not create a restriction on plant growth rather affected plant growth positively.
