rush

Rush should be kept evenly moist at all times. Water should be provided in small amounts frequently, at least 2–3 times a week, more often during particularly hot and dry spells. If overwatered, rush can develop root rot. Check the soil moisture level before deciding whether to water or not—it should never be allowed to dry out completely. In general, it is important to err on the side of caution with regard to watering.

Due to its being a grass-like plant, rush prefers full sun and well-drained, moist soil. Depending on its location, Juncus inflexus should get 6 to 8 hours of direct sunlight per day, preferably in the morning or early afternoon. During the summer when the days are longer, the rush can benefit from additional sunlight. To ensure the plant receives an adequate amount of light, provide a few hours of indirect light if necessary.

Rush can be pruned in late winter to early spring. Pruning should be done lightly, to avoid damaging the plant. Start by removing dead, diseased, or damaged stems. You can also thin out the stems to increase air circulation. This helps to reduce disease and increase growth of new and healthy stems. Aim to cut out 1/3 of old stems each season, cutting back to a few centimetres above the ground. In addition to this, you may wish to shape the growth slightly to create a desired shape.
