Watering Needs
Calceolate Milkweeds need regular watering, especially in the summer seasons when the temperatures are high. However, it is imperative not to overwater the plant to avoid waterlogging, which can lead to root rot. A deep watering once a week, as opposed to frequent shallow watering, is the best practice. During the winter season, the watering frequency can be reduced, but the soil should always remain moist, but not waterlogged, at all times.
Fertilization
Calceolate Milkweed does not require excessive fertilization as it can negatively affect the plant's natural growth cycle. It is best to fertilize the plant during the active growing period, which is typically from spring to summer.
