Siberian squill

Siberian squill should be watered liberally but not frequently. Water the soil when the top inch of soil has dried out completely, typically once a week during the growing season. It's best to apply a thorough, deep soak each time you water, providing the soil with enough water to moisten it to the bottom of the root system. As temperatures drop in late summer and early fall, gradually reduce the amount of water given to the plant. Once temperatures drop into the 50s (F) and below, stop watering altogether.

Siberian squill (Scilla siberica) grows best in full sun to partial shade. Typically, it prefers to receive 4 to 6 hours of direct sunlight per day. In areas with intense sunlight, Siberian squill may benefit from some afternoon shade. Direct sunlight during the afternoon can result in overheating and stress on the roots, leading to browning foliage and reduced blooming. When grown in partial shade, Siberian squill will generally bloom less than when grown in full sun.

Siberian squill (Scilla siberica) should be pruned back shortly after blooming. Typically, the leaves and stems should be cut down to within a few inches of the ground. This will encourage the plant to produce more blooms. If you want to maintain the foliage, pruning is still necessary to keep the plant looking its best. Begin pruning in late summer, when the foliage begins to look tired, and continue through early fall. When pruning, it's important to be careful not to remove the seedheads, as these are needed for reproduction. If you want to keep the height of the Siberian squill, it can be done by removing the tops of the flowering stems. This will also reduce the spread of any unwanted seedlings.
