This type of shrub is a perennial aquatic bush, widespread in wetlands on all continents, it lives near rivers and lakes, in clean running waters, but often it is also found near marshes. The rush develops in tufts, quickly covering large surfaces, producing underground rhizomes; it grows developing stems high up to 100-150 cm, green, without leaves or with leaves wrapped around the stem, cylindrical and flexible, usually smooth or slightly longitudinally striped; in summer it produces small fan-shaped flowers, brown-green. Most varieties are not very decorative, but some are particularly suitable for growing near small ponds in the garden, such as juncus effusus spiralis, smaller than the common reed, and with characteristic spiral growth; the juncus effusus Cuckoo, with yellow and green stripes and the Juncus effusus zebrinus, with white and green stripes.
For a better development of the reed specimens it is preferable to plant the plants of this variety in a very sunny place, at the edges of a pond or even in a completely submerged position.
This kind of shrub does not fear the cold, and in places where it does not freeze during the cold season, it is possible to favor a more compact growth by pruning it at the base in autumn, in such a way that it can develop at its best when the vegetative growth starts.
As for watering, it is obvious that, being an aquatic plant, there is a need for a constant presence of water, since the soil that houses the specimens of this particular variety must be cultivated in an environment with a high degree of humidity . If placed in a container, a solution that is however not very advisable, it is necessary to constantly keep the soil wet.
The rush prefers a slightly acid, heavy and very wet soil. The rhizomes are buried in fairly large boxes, filled with soil composed largely of peat, mixed with sand, which are then sunk underwater in a pond; if you want to keep the reeds on the edge, you can also bury them on the banks of a pond, paying attention that the water covers the plant up to the collar, just above the rhizome, so as to keep the roots in constant contact with the water.
the rush develops naturally producing a large number of new rhizomes, if desired it is possible to obtain new plants in autumn by dividing the rhizomes, trying to leave in each portion an old root and a new one; the rhizomes thus divided must be immediately buried and sunk under water to allow the new shoots to develop in the ideal environment.
Rush - Juncus effusus: Pests and diseases
Sometimes the rush can be attacked by floury cochineal and black aphids. For this reason, it is good to intervene with broad-spectrum preventive treatments to guarantee the correct protection to the specimens. Many specific products are available on the market that effectively counteract the onset of this type of problem. It is good to act promptly when you notice the signs of the presence of parasites to prevent the problem from spreading massively.
