Peruvian squill should be watered once every 7 to 14 days in the summer and once per month in the winter. The soil should remain slightly moist at all times, but must never be soggy. During each watering, give the soil a deep soaking to allow moisture to penetrate into the roots. Reduce watering frequency or amount if the soil becomes too wet or if the plant is located in a cool and humid environment, such as a basement. If the soil does begin to dry out, water thoroughly, allowing water to run through the pot's drainage holes.

Peruvian squill (Scilla peruviana) thrive best when planted in full sunlight. For optimal growth they need 6-8 hours of direct sunlight each day. Sunlight also helps them to produce larger, more vibrant flowers. If planted in an area with partial sun, they may require supplemental lighting to receive enough light for optimal growth and flowering. Avoid planting in shaded or heavily-shaded areas as the plants will not grow properly and may fail to flower.

Peruvian squill should be pruned as soon as it begins to flower. The stem and flowering heads should be cut back to the basal foliage after they flower in late spring. Doing this will encourage a more compact plant and will also prevent any unwanted self-seeding. This pruning should occur once a year, and should be carried out in late spring or early summer, at a time when the plant has finished flowering.
