Irish Moss 'Aurea'

Irish Moss prefers moderate to occasional irrigation. In the summer, water your Irish Moss once every few days, enough to keep the soil damp, and allow the soil to dry out completely between waterings. In the winter, it is best to allow your Irish Moss to dry out almost completely between waterings, about once a week. This plant is drought tolerant and does not need excessive watering.

Irish Moss does best in full sun. It will tolerate some shade but will become very sparse in large shaded areas. Six to eight hours of sunlight a day is ideal for this perennial. Optimal sunlight periods are those that are focused in the mornings and evenings when the sunlight is calm and not too strong.

Irish Moss prefers temperatures between 65°F (18°C) and 80°F (26°C). It can withstand colder temperatures down to 20°F (-7°C). Direct temperature extremes can lead to wilting, discoloration, and even death, so use caution when exposing this plant to extreme temperatures.

Irish Moss does best in average humidity levels, but it can tolerate low humidity. If needed, you can add some humidity to your plants by misting them with a spray bottle once or twice a week. Make sure not to spray them too often, as this may lead to root rot.

Irish Moss does best in well-drained soil that is rich in organic matter. It can thrive in sandy or loamy soils, or a combination of the two. The ideal soil should have a balanced pH level with slightly acidic soils preferred. Adding compost to the soil is beneficial as it will add additional nutrients to the soil.

Irish Moss does not need additional fertilization. It will do well in soils that are already supplemented with organic matter. If needed, use a balanced, water-soluble fertilizer once a month in the growing season. Be sure to avoid over fertilizing as this can lead to leaf burning or other nutrient deficiencies.

Irish Moss is rarely affected by pests. Aphids and slugs can cause damage if infestations become severe. Inspect the plant daily for signs of pests and remove any visible pests with your fingers or tweezers. A strong spray of water can also help. If the problem persists, use appropriate insecticides and fungicides, available at your local nursery, to control the infestation.

Irish Moss does not need frequent repotting. Repotting should only be done if the plant is growing too large for its pot. When it is time to repot, choose a pot that is only 1 to 2-inches larger than the current pot and make sure there is adequate drainage. Use a well-draining soil mix that is rich in organic matter.

Irish Moss can be lightly pruned throughout the year. Dead or damaged leaves can be removed, as can any leaves that are not growing as desired. Be sure to avoid pruning too much as it may encourage disease and can weaken your plants. It is best to prune lightly and selectively, focusing on areas that appear unkempt or untidy.

Irish Moss does not need additional mulching. It will spread by itself and the mulch may not be necessary. If the soil is not well-draining, adding some mulch can help. Organic mulch, such as shredded leaves or wood chips, is ideal.

Irish Moss can be propagated through division or cuttings. When dividing, wait until the plant is dormant and then dig up the roots and divide them into smaller parts with a sharp knife. When using cuttings, take semi-hardwood cuttings in early to mid-summer and place them in moist, well-draining soil. Keep the cuttings in bright but indirect light until roots begin to form, which can take anywhere from four to eight weeks.

Irish Moss does not require additional support. It will grow on its own in a mat form. A stake may be placed beneath the plant if necessary to help support the plant's weight, but avoid too much support as this can lead to weak stems.

Irish Moss does not have a defined rest period. While it will go dormant naturally over the winter or in times of extreme heat, the plant is evergreen and remains green in most climates. If the plant appears to be losing its color, ensure that it is receiving enough light and water.

Irish Moss is not toxic to cats, dogs, and other pets. It is, however, a choking hazard, so it is best to keep cats and small animals away. Eating parts of the plant is not recommended as it may cause digestive issues.
