this study inherits the research results on the production of compost made from banana stem after harvesting
biochar was created from the post-maintenance pruned urban twigs of the research team to serve as a research nutritional growing medium from compost, biochar, soil and coir. The results recorded: (i) the kind of growing medium was determined suitable for seedling at the nursery and plant at vertical garden that applying for the 4 species (Epipremnum aureum, Dracaena surculosa, Pseuderanthemum reticulatum and Dracaena angustifolia) containing composition: soil 30% + coir 20% + biochar 25% + compost 25%. The survival rate of seedlings was 73.5% to 98.5% when applying the nutrient medium above. The seedlings were healthy, achieve the best growth target in terms of height and number of leaves
(li) two wall-mounted vertical garden models have been designed with applying automatic irrigation equipment installed with the dimensions of length x height x width of 1000 x 1000 x 30 mm. After 4 weeks of transplanting, all studied plants showed good adaptability to the new habitat. This result opens up a new approach closer to urban households whom living at the space to plant trees is limited.
