Iris Reticulata Plant Care

In areas that do not receive adequate Winter rainfall, water well after planting and water occasionally until foliage and flowers emerge. Ensure plants receive adequate water during the growing season, but once they die down and go into dormancy the bulb does not require any water at all. Like all bulbs, Iris Reticulata rots easily if over watered or if soil is too heavy and poorly drained.

If the soil has been well prepared fertilising isn’t necessary. If soil is of poor quality blood and bone can be applied after leaves begin to emerge.

Bulbs may be left undisturbed for years. If lifting bulbs is required, do so once the foliage has died down completely and store in a warm and airy position. It is important to let the foliage die back naturally as this allows the bulbs to store energy for the next season.

Watch for aphids as the weather warms up.
