CROQUET LAWN MATTERS CONTINUED 4. Survival Mechanisms
It is generally not effective at killing moss spores. Here’s why: Spores’ Resilience: Moss spores are highly durable, with tough outer walls that protect them from environmental and chemical stresses. Iron sulphate targets active moss tissues, but spores in their dormant state remain unaffected. Chemical Resistance: Unlike the vegetative parts of moss, spores do not rely on photosynthesis or cellular hydration in the same way, making them less vulnerable to the mechanisms by which iron sulphate works. How to mix Soluble Iron I use a 10 litre bucket, a 1 litre scoop, a cordless drill and a paint paddle. To cover one croquet lawn, measure about two and a half litres of crystals into the bucket, add water then stir using the paint paddle for 60 seconds. Pour off into your sprayer being careful not to pour any residue. If there is residue, add more water and stir again. Be sure to use grade 1 Soluble Iron because this will dissolve really well at any temperature and will not clog sprayers. After spraying you must thoroughly rinse your sprayer and pump plenty of clean water through so that no product is left in the pump or pipes. Any product left in the sprayer could recrystallise and wreck the sprayer. For smaller quantities you could use a watering can and rose rather than a sprayer.
Dormancy: Moss spores can remain dormant for extended periods, waiting for the right conditions to germinate. Rapid Growth: Moss establishes and grows quickly, outcompeting grass in poor conditions. Moss spores are remarkably resilient and can survive for many years, often ranging from several years to even decades under the right conditions. This long lifespan is due to their ability to enter a dormant state, which helps them endure unfavorable environmental conditions like drought, Iron sulphate is an effective treatment for killing moss in lawns. Its action primarily affects the moss itself, targeting its tissues and disrupting its ability to survive. Tissue Desiccation: When applied, iron sulphate dries out moss by chemically reacting with its cells. This leads to dehydration and causes the moss to blacken and die within days. Impact on Chlorophyll: Iron ions interfere with the moss's ability to perform photosynthesis effectively, further contributing to its decline. Can Soluble Iron kill Moss Spores? extreme temperatures, or lack of nutrients. How Soluble Iron (Iron Sulphate) Kills Moss
