When your
Red Spider lily is growing, you will need to water about once a week. As the temperature rises, the soil will dry out faster and you will need to increase the frequency of watering. A dry soil environment will be more friendly to your
Red Spider lily than an excessively wet soil environment.
Red Spider lily will become dormant during summer and the above-ground parts will completely dry up and die after dormancy,. if you planted it outdoors, you shouldn't need to water it. Moreover, if there's plenty of rain in your region, you should consider digging them out to protect the buds from rot due to too much water.
If you planted it in pots, you should stop watering your
Red Spider lily completely after the dormant part dries out. After the above-ground part dries out completely, dig up the buds and store them in a cool location or stop watering them completely to keep the soil dry. Resume watering until the next sowing season. Or keep them in the soil in a cool location until the next growing season.
