Moss Control

Moss Control

Here in the Edinburgh and its surrounding areas, Blue Iris Lawn Care have seen a steady increase in the quantity of moss we are seeing in new customers lawns with some lawns being more moss than grass. If the conditions in your lawn aren’t perfect, and they rarely are you may have a moss problem, requiring a Moss Control Programme.  In other words, the natural balance in your lawn is towards moss and away from grass. Without any intervention, the problem may get worse and, in some cases so bad that you have all moss and no grass!

There Are Three Main Causes Of Moss In Lawns

Lawn care practices

  • Scalping the lawn by mowing the grass too short
  • Not following the ‘one-third rule’ for mowing which is as a result of:
  • Infrequent grass cutting
  • Scalping high points because of a bumpy lawn
  • Not aerating heavily used or compacted areas
  • Poor or inadequate use of fertiliser products
  • Not repairing damage from heavy use
  • Leaves not being removing  in autumn
  • Not removing excess thatch

‘Local’ environmental factors

  • Shady lawns
  • Clay soils or poor drainage
  • Poor air circulation and heavy dew
  • Dry areas such as lawn edges
  • North facing lawns
  • Acidic soil

Climatic factors

Ideal conditions for moss growth:

  • Wet climate
  • Excess rainfall
  • Cloudy cool summers

Poor conditions for grass growth:

  • Long hot summers
  • Dry summers
  • Cold dry spring

Moss can clearly grow in your lawn in quite a wide variety of conditions. The more suitable the conditions, however, does not always mean more moss because lawn care practices can have the greater influence. A lawn scalped once a month with dull blades may well have moss even if it’s in a sunny dry location! A well maintained but slightly shady lawn, however, may be no moss.

Therefore, a lawn in an ideal environment with good lawn care practices will have little or no moss. The fact of the matter is that in this situation the grass thrives and the moss doesn’t get a look in. The grass is weakened is only when conditions are against it which in turn allows moss to take a hold.

Why Is Moss So Bad In Our Lawns This Year?

Moss thrives in damp, shady, cool but not cold conditions. Recent winters in the central Scotland have been mild. The winter of 2016/2017 seems to have been especially mild, with spring coming early. This has provided the ideal growing conditions for months. If your lawn has an area of shade, is overly compacted, suffers from poor drainage or is in an acidic soil area, then it will most likely that moss has become an issue. In the UK there are hundreds of species of mosses, but only around 30 of those are found in lawns and nearly all of those are treated in the same way. 

Curing a moss problem in a lawn is never an easy task, nor is there a quick fix. It may take several seasons to literally bully out of the way. If there has been a moss problem for a long time, annual control and regular hard work, maybe the only choice.

Find The Cure For A Mossy Lawn

Blue Iris Lawn Care can provide a comprehensive lawn care and moss control programme to remove moss from your lawn. However, the best practice is to also identify why the grass has weakened to allow the moss flourish in the first place.  And to remedy that problem, so that in future years the grass can become strong enough to not allow the moss to establish. As your local lawn care experts, Blue Iris Lawn Care can help you to identify the causes of moss, and advise on a course of action to help.

When To Start

It is safe to say that Autumn is undoubtedly the best time to start a moss control programme. However, the process can be started at any time of year. We will apply a moss control treatment as possible and will reapply as soon as possible at the start of the year (late February / early March). You should avoid waiting until spring as this will allow the moss to release its spores and die back naturally. Continuing its life cycle and infesting the soil, being ready to come back with a vengeance the next Autumn!

The now dead moss can be removed by scarifying the lawn, two or three weeks after the moss was treated. This aggressive process involves mechanically pulling moss and thatch out of the lawn. The lawn can then be aerated, fertilised and over-seeded if required. A top dressing can also be applied to improve the soil structure, plant the seed, and help to level the lawn.

Improve the lawn

If moss has been a problem for many years, this will not be the end of the story. Your lawn may well still contain many millions of moss spores and, given the chance, these will come back in the autumn. To prevent re-infestation, keep the lawn healthy and thick by utilising an annual Treatment Programme from Blue Iris Lawn Care – feeding regularly with the Blue Iris Lawn Care Seasonal Treatments, and addressing any other issues within the lawn.  We will also advise of any other issues which may be contributing to the problem, such as cutting back overhanging trees to reduce the shade
