What are some recommended companion plants?
Plants such as creeping thyme, hosta, foamflower and heuchera all work well together.
How is Irish Moss used in the landscape?
Irish moss is typically used as a ground cover, in rock gardens, or in containers.
Do I need to fertilize my Irish Moss plants?
Apply a slow-release fertilizer each spring to encourage your Irish moss to grow evenly to a height of 1 to 2 inches. It's best to choose a balanced 5-5-5 NPK fertilizer or a formula with slightly lower nitrogen content. Excess nitrogen from over-fertilization can lead to erratic growth, causing the moss to develop an undulating shape instead of maintaining a compact, low profile.
What is the best way to water Irish moss plants?
Finding the right watering balance for Irish moss can be challenging. Overwatering or underwatering can lead to brown patches. Ideally, the soil should remain consistently moist but not soggy. Water your Irish moss in the morning to prevent early evaporation; a soaker hose set to a gentle rainfall mode is ideal. Remember, Irish moss is not drought-tolerant, so it requires regular watering every few days, depending on the heat.
Do I need to prune my plants?
Trimming Irish moss is not essential; however, you may wish to cut it back from steps, pavers, and other structures to maintain a tidy appearance. If you decide to prune, use clean scissors or shears for the task. Otherwise, Irish moss thrives best when allowed to grow naturally.
Can Irish Moss withstand foot traffic?
Absolutely! Once established, Irish moss can tolerate light foot traffic; however, it's advisable to avoid walking on it until it is fully settled in your landscape. If you're in search of a more resilient ground cover that can endure wear and tear, consider choosing creeping thyme instead.
