For giliastrum, choose a site with well-draining soil and full sun exposure. Typically, they thrive in sandy or loamy soils that are not too rich in organic matter, mirroring their native habitats. Water needs vary; allow soil to dry between waterings. To plant, till the area, integrate a light starter fertilizer, space the plants according to their expected size, and water thoroughly. Mulching helps retain moisture and control weeds. It's vital to consider the particular needs of different giliastrum species, as some may have specific environmental preferences.
