watering

Cupflower (Nierembergia linariifolia) should be watered twice a week, allowing soil to dry out slightly between waterings. It is best to water the plant thoroughly, soaking the soil until water runs through the drainage holes in the bottom of the container. Avoid overwatering, as cupflower plants are susceptible to root rot. In general, water the plants until moisture is observed 4 to 6 inches deep in the soil. During the hotter months, plants may require more frequent watering so the soil stays moist.

In regions with hotter climates, the plant will take full sun, but will produce more flowers and look its best when given several hours of shade a day. The amount of sunlight should total 6-8 hours per day for best performance.

Pruning should be done minimally, leaving the chance for new growth. Ideally, stems should not be pruned back more than 1/3 of their total length.
