WaterThe common mallow, also known as Lavatera trimestris, prefers consistent moisture and should be watered deeply once a week, providing a couple of gallons per plant depending on soil type and weather conditions. During hot summer days, it may require additional water to prevent the soil from completely drying out. It's important to avoid overhead watering to reduce the risk of leaf diseases; instead, water at the base of the plant. Cut back on watering as the plant matures and during the fall to encourage sturdiness.
LightThe common mallow thrives in a location that receives full sun exposure for at least six to eight hours daily. While it can tolerate some light shade, optimal blooming and growth are achieved in a sunny spot. An open area that is not shaded by taller plants or structures is ideal for the common mallow.
TemperatureCommon mallow grows best in a temperature range between 50°F and 85°F. It can survive minimum temperatures down to around 40°F but will not endure frost conditions. The ideal growing conditions for these plants are in areas where temperatures are consistently warm, though not excessively hot.
PruningCommon mallow should be pruned to remove dead or damaged growth and to shape the plant, which encourages new growth and flowering. Pruning is often done in late winter or early spring, before new growth begins. Regular deadheading of spent blooms can also be performed to maintain a tidy appearance and promote continuous flowering.
CleaningAs needed

Life cycleLavatera trimestris, commonly known as annual mallow, begins its life cycle as a seed, which can be sown directly into well-drained soil after the last frost date. Upon germination, which can take 1-2 weeks, the seedling emerges with cotyledons before developing its true leaves. In the vegetative stage, the plant develops a robust stem and foliage, preparing for flowering. Flowering typically occurs in summer, and the plant produces showy, funnel-shaped blooms which may attract pollinators such as bees and butterflies. After pollination, the flowers develop into dry, disk-shaped fruits, which contain the seeds for the next generation. As an annual, after setting seed, the plant completes its life cycle by dying, while the seeds overwinter to germinate the following spring.
PropogationPropogation time
Spring to early summer
Propogation: Lavatera trimestris, commonly known as the annual mallow or rose mallow, is most commonly propagated through seeds. The ideal time to sow the seeds is in spring after the last frost has passed, when the soil has begun to warm up. An effective method is to scatter the seeds thinly onto well-drained soil in a sunny location, covering them with a light layer of soil about 1/4 inch (approximately 6 millimeters) deep. Water the sown area gently but thoroughly to moisten the soil without causing the seeds to be washed away. Germination usually occurs within 2-3 weeks, and it is important to keep the soil consistently moist during this period. Once the seedlings are large enough to handle, they can be thinned out or transplanted to their final growing positions, ensuring they have ample space to develop.
