The urban trees, as well as the vegetal elements that are part of the urban garden contribute to an environmental equilibrium and to the welfare of the urban population. Being located in urban areas, this vegetation requires periodic replacements, so it is necessary to produce sufficient quantities of these vegetables in order to meet demand. The ideal way to produce these vegetables is to use materials that are sustainable and whose production does not harm the environment. In the aims of making the use of this residue possible, composting furrows were mounted with this triturated material. The furrows were monitored, and their temperature checked, besides being plowed and watered periodically, and after about 100 days the material was taken from the furrows, dried outdoors and stored. to test the compost, an experiment in which two ornamental species (Acalypha wilkesiana m. arg. and Thunbergia erecta T. anders), propagated by cuttings, were used. They were mounted using the following substrates: 100% soil, 100% pruning compost, 100% commercial substrate, 30% of streets' and avenues' cleaning residues + 70% pruning compost, 40% clay substrate + 60% pruning compost and 30% sand + 70% pruning compost, after evaluating the biometric parameters, it was clear that the substrates with the bigger percentage of pruning compost had the better results.
