The present disclosure relates to vertical gardens. The present disclosure envisages a vertical lawn. The vertical lawn includes an artificial substrate, a water-proofing layer applied on the substrate, and a drainage sheet provided on the water-proofing layer. The drainage sheet has a plurality of projections configured thereon to facilitate flow of water therebetween. A geotextile sheet is fitted on an operative front surface of the drainage sheet. A hydrophilic rock mineral wool layer is secured to the operative front surface of the geotextile sheet. The rock mineral wool layer configured to absorb and retain moisture therein. A lawn mat secured to the rock mineral wool layer.

A synthetic soil substrate system has a plurality of synthetic soil substrate layers that are individually designed to promote plant growth as the roots grow into the layer and as a function of the growth stage. The synthetic soil substrate layers may be planar or may be concentrically arranged with a first synthetic soil substrate ring layer being configured inside of a second synthetic soil substrate ring layer. A synthetic soil substrate has pores that are configured for plant growth and retention and/or deliver of water and growth additives. The average pore size of a first synthetic soil substrate layer may be substantially different from the average pore size of an adjacent synthetic soil substrate layer. Also, the pore structure or shape of the pores may be different between synthetic soil substrate layers, The synthetic soil substrate may have an integral growth additive retained in the pores.

A method of manufacturing a growing medium comprises accumulating a particulate material. The particulate material comprises particles having a range of particle sizes. The method further comprises agitating the particulate material which causes smaller particles of particulate material to sink to the bottom of the growing medium under gravity and to thereby displace larger particles of particulate material to the top of the growing medium. There is also provided a growing medium comprising a particulate material defining a volume of particulate material which comprises particles having a range of particle sizes. The concentration of smaller particles of particulate material increases from the bottom of the volume of the particulate material to the top of the volume of the particulate material. The concentration of larger particles of particulate material decreases from the bottom of the volume of particulate material to the top of the volume of particulate material.
