spider lily

Spider lily (Hymenocallis festalis 'Zwanenburg') requires regular watering. Water the plant when the soil is dry to a depth of 1-2 inches. In summer, water the spider lily about once every 5-7 days. Make sure the soil is still moist but not soggy. In spring and summer, this may require more frequent watering. In winter, water the spider lily only when the soil is dry. The long dry period associated with winter often means that the spider lily does not need to be watered more than every 2-3 weeks. In periods of extreme drought, you may need to water the plant more often.

Spider lilies require full sun exposure for at least 6-8 hours per day in order to thrive. They do best in temperatures between 65 and 85 degrees Fahrenheit, and should be protected from strong winds and direct afternoon sunlight. During the summer months, they should be kept consistently moist, as they have a high water requirement. When the days are shorter and the temperatures cooler, they require less water and should even be allowed to go slightly dry. During the cold months, their water needs are minimal and they should be moved indoors if temperatures dip below 55 degrees Fahrenheit. Providing the right amount of sunlight, water and temperature for spider lilies helps ensure that they will flower annually.

Spider lily should be pruned at the right time for optimum health and maximum blooming. Generally, the best time to prune spider lilies is in late winter or early spring. At this time, any old or unhealthy foliage can be removed, as well as dead flower stalks. In addition, a light shaping of the plant can be done to help encourage new growth. However, avoid over-pruning, as it can impede the growth of the spider lily. Additionally, if you need to prune your spider lily in summer or autumn, limit it to deadheading or removing any damaged leaves only.
