Mallows plants generally thrive in sandy or rocky soils with good drainage, requiring full to partial sun exposure and moderate watering. Prepare the planting area by loosening the soil and enriching it with compost if necessary. When planting, ensure the roots are well covered but the stem base is at ground level. For initial care, water the plants well, but avoid waterlogging. While many mallows species share these general desires, individual needs may vary, making it important to understand the specific guidelines for your chosen species.
