Indoor plants
Juncus
Juncus
Family Juncaceae. All these plants are intended to be grown on the shores of water bodies, so even in indoor conditions they require very humid care.
Never allow the rootball to become chilled, otherwise the plant — as it does in winter in natural conditions — will fall into dormancy, and then you should let it "sleep" until spring. There should always be water in the saucer; the rootball must never dry out. Ideally place a small fountain or simply many shallow dishes of water near this plant so that it feels "at home." And keep it warm — no drafts, open windows, etc. Provide additional lighting, because warmth and humidity without light will not produce good results.
Three important components: water + warmth + ambient air humidity. In winter, when the heating season begins, the air humidity drops sharply — and this is deadly for a rush. Therefore I would advise planting it in a fairly shallow but wide dish with a large layer of expanded clay (LECA) on the bottom — it will protect the roots from simple rotting and at the same time prevent drying out, since it will always supply moisture from the saucer. Do not pour a lot of water into a deep saucer — just top up the water daily. Also place expanded clay on top of the pot-dish — it will prevent the top layer of soil from drying out. To increase the humidity around the plant, arrange dishes of water and mist the air around the plant.
