November 2018 Lawn Diary
This Month in a Nutshell
November pretty much concludes the year's lawn care; mowing more or less comes to an end though the mower may get plenty of use sucking up leaves and the moss may keep you busy for a while yet!
Summary 'to do' list for November:
- Perhaps the last cut of the year
- Possible late Fertilising due to late grass growth
- Applications of Ferrous Sulphate
- Clearing leaves
A decent October, not too wet, not too cold with little frost!. Not as good as last year but a reasonable end to a super summer. Lots of you scarifying and over seeding VERY late and sometimes it's a risk you have to take. I hope you get away with it and have a great lawn going into the winter otherwise mother nature will set a few of her own seeds in the empty spaces making more work for the spring!
As we move into November expect frosts to become more frequent so be careful if aerating as frost can cause the lawn to heave. However, that isn't the only problem: the cooler wetter conditions are now bringing on the moss together with an abundance of toadstools, worms, worm casts and though beneficial, worms that is, they can cause considerable mess. Here's what the Met Office has to say for November:
UK Outlook for Sunday 28 Oct 2018 to Tuesday 6 Nov 2018:
By Sunday a cold arctic airflow will be in place across the UK, bringing a good deal of sunshine and some heavy showers, mainly around eastern coastal areas. Hail and thunder is likely, with snow showers over higher ground in the north, and it will feel bitter in exposed areas. Confidence lowers by Monday, but it is most likely that many places will see a dry and bright day with showers continuing in the east, but widespread frost overnight. From Tuesday a spell of increasingly unsettled weather looks likely, with showers or longer spells of rain between brighter interludes. Gales or severe gales can be expected, but temperatures should begin to recover to around normal by Friday with milder, unsettled conditions likely to dominate until the end of the period.
UK Outlook for Wednesday 7 Nov 2018 to Wednesday 21 Nov 2018:
Mild but unsettled conditions are likely to be in place by the second week of November with dry and bright spells interspersed with bands of rain or showers. Confidence into and beyond the middle of November is low, but there are some signs of high pressure developing which could help to divert weather systems away from the UK. If such a scenario develops then longer settled spells could bring largely dry conditions, but a greater chance of overnight frost and fog, and daytime temperatures below normal. Any rain or showers could fall as snow over northern hills, and any milder interludes are likely to be short-lived.
Please be advised that we have very limited opening and staffing during December. As usual there is no phone support and slow email support - we need a rest! For a better service please get any winter lawn supplies in this month.
Chances are your next cut will be your last. In Scotland you have more than likely finished mowing. If you do mow make sure you've raised the mowing height by 1-2 settings. In addition, don't be afraid to give the lawn a light HIGH topping on a dry day anytime over winter to keep it looking tidy.
If cooler wet weather has caused a resurgence of moss raise the mowing height to the top so you just clip the leaves otherwise you'll enter spring with more moss than grass!
If you no longer think you'll need the mower give it a good clean and a service. This is quite easy to do. See the section on mower Cleaning & Maintenance.The mower can be useful for sucking up leaves so if leaves are a problem service the machine in January.
It's getting a bit late for applying autumn fertiliser in the north - certainly from the borders northwards. If temperatures are typical for November then everyone else can still play outside until mid November with those in the south being able to feed until end November. If you need to add fertiliser make sure it is low dose slow release nitrogen and high potassium such as Lawnsmith AUTUMN Fertiliser or, from now through winter, use a high iron winter fertiliser such as WINTER GREEN.
If you have already fertilised and want to give the lawn a bit extra to protect from disease, reduce moss activity and also give the grass a green-up try a medium strength liquid application of Ferrous Sulphate. This is also useful to slightly reduce worm activity which may be evident in the cooler wetter conditions.
Definitely a bit late. The best you will achieve with weed killer in these cool conditions is to make them poorly. Best wait now until the spring.
Many of you will soon be experiencing major problems with moss in the lawn as the weather cools and grass growth stops. For now you're too late to do anything radical as you'll be left with a much disfigured lawn.
Taking a gentler approach may well pay dividends however. If the moss infestation isn't too severe apply Ferrous Sulphate (Soluble Iron) in solution at 4-5g per square metre once or twice over the winter period. Alternatively apply Winter Green High Iron Fertiliser once over winter. In spring you will have far less moss to rake out - many of you may not even need to do that! On the other hand, if you are already over run with moss there is not much to be done other than wait until spring, treat with Ferrous Sulphate, rake it out and over seed with a good grass seed. By starting with a clean slate next year you should be able to keep the moss in check next winter with just ferrous sulphate.
For those of you with concerns for safety of children and pets that are likely to be on the lawn soon after treating you can now use a chemical free product in your treatment program. See MossOff in the moss killer products link below.
Only do this prior to applying ferrous sulphate if the weather has been dry. A light sprinkle to damp things down is all that is required.
We are coming to the end of the period for hollow tine aeration and possibly slitting. If you do use these methods then make sure there is no frost in the forecast in the short term as the lawn will quite possibly freeze and swell if frost occurs.
Using other forms of lawn aeration equipment is very beneficial and less prone to heaving in frost. Anything that makes a small hole whether powered or manual such as aerator sandals, rolling lawn aerator or the garden fork.
No way Jose
Leaves: Weekly collection is very important for grass health and to reduce moss, disease and worm activity. If you have a rotary mower and the leaves are dry use it to suck up the leaves.
Make sure conditions are not too wet or soft before working on the lawn. If the surface is firm then re-cutting edges is in order plus any repairs using turf.
Disease: Two diseases rust and fusarium may be present at this time of year. Fusarium is the more likely one as we go into November with high risk during the damp foggy months of November. If the risk of fusarium increases we will issue a lawn alert.
Fusarium can also be a sign of poor turf health, high thatch levels, poor air circulation, compaction or just persistent wet conditions. Do look for possible causes though as you can resolve any problems ready for next year.
Worms: Though it's best to treat for worms at the first sign, they will continue to surface throughout the winter and produce muddy casts that cause mowing problems. Worms are beneficial in that they digest organic matter providing nutrients and enriching the soil. They also do some valuable aeration. A lawn with worms is generally far healthier than one without.
The problem end of the worm is the cast and your lawn may be covered with them by now. Brushing doesn't work when the casts are wet but you can reduce the casting. Making the surface of the soil less palatable is how most worm control products work and we still believe that an application of Soluble Iron or Ferrous Sulphate is as reliable as most and definately the most cost effective control method. It is ideal if you are already using it as part of a moss control program.
Finally, toadstools will be appearing which generally should not be of concern other than to keep you busy picking them out.
Unlikely to be required until next spring unless you've over sowed with grass seed earlier in the autumn.
Too late. Wait now until good growth in spring.
If you've been waiting for cooler wetter weather for turfing them the time is ripe from now into March at least.
