roof iris

Roof iris (Iris tectorum) appreciate water on a regular basis. They are typically watered every 7-10 days in the summer, or when the soil feels dry to the touch. If the air is particularly dry, you may need to water more frequently. It is also beneficial to mist the leaves every so often. During the winter months, water less frequently as the plant will not be as actively growing. Water only when the soil is close to drying out.

Roof Iris (Iris tectorum) grows best when it receives between 6 and 10 hours of direct sunlight every day. This is a medium-light-loving plant that will thrive if given this amount of natural light, which is equivalent to roughly 15,000 to 30,000 lumens of illumination. If it receives any less than this, the Roof Iris will become lanky and weak and may even fail to flower altogether. Full sun should be given in the morning through mid-afternoon, and then some afternoon shade should be given to avoid sunburn in hot climates. While the Roof Iris will tolerate partial shade, it should still be given some direct sun for at least 4 to 6 hours per day. This will help to ensure its healthy growth and flowering.

Roof Iris is a deciduous plant, which means it should be pruned once its leaves have started to yellow and lose their colour before the winter season. Pruning your Roof Iris should generally take place in late summer or early autumn. When pruning, remove any dead, damaged or diseased foliage and stems. Additionally, shorten and thin out any overcrowded shoots, ideally to keep the stems at a few inches above the ground. Take care not to prune too severely as this can cause over stimulation of new shoot growth, which is not ideal in the cooler months. By taking these initial steps at pruning, this can help reduce the need for large pruning jobs in early spring. If your Roof Iris has grown too large, an extensive pruning can be done in spring. This will help to reduce the overall size of the plant and encourage strong, new growth. When pruning, make sure to prune each stem evenly and make sure not to cut too deeply as this can harm the plant. If necessary, also apply a balanced fertilizer before and after pruning. Overall, Roof Iris should be pruned once its foliage begins to yellow, typically late summer or early autumn. Prune by cutting back dead, damaged or diseased foliage and stems. You can also shorten and thin out any overcrowded shoots. If needed, a more extensive prune can be done in early spring. Always take care to prune evenly and to not overly cut any stems. Following these steps can help ensure a healthy Roof Iris.
