Your Spiralis loves the light. Originally, as a grass, it has always grown on the ground, even in the full sunshine. It the summer it will grow well and flourish, and with a little luck, you might get it to bloom in little off-white flowers.
Water and fertilisation
The Juncus effuses has its root in the watery environment of moist soil and swamp. It likes the soil on which it lives to be wet. Every other week you can give it some fertilizer.
Spiralis can withstand all temperatures, except frost. It will not grow as well in the cold as in the warmth, but it will not die out.
