Did you provide at least three to four hours of bright, indirect sunlight for your plant?
Did you planted your silver quill in well-drained, rich soil or a potting mix?
Are you making sure that your silver quill isn't left in temperatures below 30 degrees Fahrenheit?
Do you allow the top inch of the soil or potting medium to dry out before watering?
Do you feed your silver squill regularly during the growing season?
Do you keep your silver squill free of pests and diseases?
The silver squill will require some access to the bright sun (for at least three to four hours per day), but it should remain indirect. It can also adapt to the shade and is often found growing in closed evergreen woodland.
The silver quill will grow best in rich soil, but it must be well-drained. Preferably, it will be humus-rich and sandy. If you live in a warmer climate and want to plant your silver quill outdoors, find it a rocky and partially shaded area of the garden.
Once they're established, the silver squill requires minimal watering - they are considered to be drought-tolerant, much like succulents. Be sure to allow the top inch of the soil or potting medium to dry out before watering in the warmer months. The plant will be in its rest phase in the winter months, so you should water half as often.
During its growing season, liquid fertilizer should be applied to the soil monthly. Don't fertilize during winter because the plant will be in the rest phase.
Good job! You are taking good care of your silver squill.
Silver squill plant doesn’t experience any severe disease or pest problems. However, be on the lookout for spider mites, slugs, snails, and aphids. These pests must be removed with light shaking of the plant or sprayed with light insecticide if the pests aren’t easily shaken off. Overwatering silver squill will result in roots rotting.

Hi! I’m Sreten Filipović. I graduated from the Faculty of Agriculture at the University of Belgrade, with a master's degree in Environmental Protection in Agricultural Systems. I’ve worked as a researcher at Finland's Natural Resources Institute (LUKE) on a project aimed at adapting south-western Finland to drought episodes. I founded a consulting agency in the field of environment and agriculture to help farmers who want to implement the principles of sustainability on their farms. I’m also a founding member of the nonprofit organization Ecogenesis from Belgrade whose main goal is non-formal education on the environment and ecology. In my spare time, I like to write blog posts about sustainability, the environment, animal farming, horticulture, and plant protection. I’ve also published several science-fiction short stories.
