Pack size 20kg or 25kg Both of these are the same product. The 25kg bag is a better deal but delivery is longer. There are many grades of Ferrous Sulphate and some don't dissolve well and can be very damaging to sprayers. This is a crystaline product and it dissolves in water very well even at low temperatures. The best dilution for killing moss is 5kg (5 litres) in 100litres of water to cover one croquet lawn (1000sq metres). Moss can only be killed by contact so it is important to use a lot of water so that it reaches all the plant. The product will stain clothing, paving slabs etc. Remove your shoes/boots before walking on your expensive persian carpet. It is not toxic to pets or humans when used as directed.

Make sure there is already some water in your spray tank before adding the Iron mixture (this avoids the feed pipe filling with concentrate). DO NOT put crystals into the sprayer, they must be dissolved in a bucket/barrel first. I use a wine making barrel for mixing and a 1 litre scoop for measuring. Scoop in a litre of product and pour water into the bucket/barrel. Stir and filter off into the sprayer. There will always be some deposit at the bottom of the bucket. repeat this mixing until you have dissolved the required amount. Then top up the spray tank and agitate. Moss Moss produces spores twice a year so should be treated in Spring and Autumn to kill the moss and prevent new spores ripening. Moss doesn’t have a vascular system and the roots have no function except to hold onto the ground, so re-growth is caused by spores in the soil not from roots. The winter feed mentioned above will reduce the moss to some extent but is not as strong as soluble Iron. The grade of iron that I supply dissolves well even in very cold water, is widely used by professionals and works really well. One bag is enough to treat the whole lawn five times so is very cost effective, there are cheaper alternatives but Iron comes in many grades and some can be hard to dissolve and very damaging to sprayers. At the dilution that I recommend it will blacken moss and I usually leave it and let the grass grow through, that way the surface isn’t disrupted. However, you can rake lightly but try not to disturb the rootzone. Be careful to wash your sprayer out very thoroughly so that no iron is left in the pipes or pump as it will re-crystalise and potentially ruin the sprayer. For spot treatment, a watering can and fine rose can be used. |
