Mohr's Barbara's-buttons

Marshallia mohrii needs to be watered about once a week with around 1 inch of water. Watering in the morning is best as it gives the plant time to dry off before nightfall. Make sure the soil is allowed to dry out between waterings to avoid rot. Be sure not to over water as this can cause root rot. Watering should be adjusted depending on the soil, climate, and season. In dry climates, it may need water more frequently or it could even need twice-weekly watering in the summer months.

Mohr's Barbara's-buttons require a minimum of 5-6 hours of direct sunlight per day to thrive. Depending on your climate, they may benefit from more hours of sunlight. In cooler climates, 8-10 hours of direct, filtered sunlight is recommended. It is important to avoid extreme temperatures, and protection from excessive midday heat and high winds is necessary. For optimal growth, the best time to provide direct light for Mohr's Barbara's-buttons is in the early morning and early evening, when sunlight is less intense.

Marshallia mohrii requires pruning annually in late winter or early spring. Pruning should involve deadheading, pinching off old flowers, thinning out stems, and formative pruning. It is important to deadhead the spent flowers to keep the plant looking neat and to encourage more blooms. Pinching off old flowers also helps prevent unwanted self-seeding. Thinning out overly crowded stems helps to encourage the development of more flowers on a single stem, as well as improving air circulation around the plant. Finally, formative pruning is important to keep the plant neat and within a desired shape. To do this, prune off any weak or stray stems, and trim back young shoots to the desired size. Be sure to use clean, sharp pruners when pruning to minimize damage to the plant.
