With summer fading away, the nights drawing in and wetter, cooler weather moving over the North West of England, grass moves into a different phase of growth than other times of the year, and hence you should provide the correct nutrients to help feed it. During September, October and November, you should apply a fertiliser with reduced amounts of Nitrogen (N) and increased amounts of Phosphorus (P) and Potassium (K). This directs growth down towards the roots, rather upwards to the leaves, making the plant stronger and better prepared for the coming winter months.
The fourth Lawnscience standard treatment of the season is usually a fine grain, carefully selected, slow release fertiliser which gently feeds the grass roots. If a lawn regeneration treatment or aeration treatment is required, then the autumn fertilisation and weed kill treatment should be applied straight after, so that your lawn gains the most benefit from it.
If necessary, I also spot-apply a full-spectrum liquid herbicide, just to tidy up any remaining weeds that may have germinated since the application of the summer treatment.
Information about Standard Treatment 4
Main benefits of the fourth lawn treatment
- Encourages root growth, giving a stronger grass plant.
- Improves the disease resistance of the grass.
- Help grass prepare for cooler winter temperatures.
- Keeps your lawn weed-free.
Disadvantages of the fourth lawn treatment
- A weed control cannot be applied at the same time as an over-seeding treatment, so any weeds will need to be treated after winter.
- The main benefits of the autumn treatment will not really be shown in the lawn until the lawn starts growing again in the spring.
Recommended time of year for application
The fourth fertilisation and weed control treatment of the year is applied in late August, September, October or November. However, the exact time will depend on the local weather conditions and the date of the previous treatments.
Weather conditions needed for application
Treatment 4 can be applied in nearly all weather conditions, although care should be taken to remove leaves on the lawn before treating.
There is no preparation needed before the autumn treatment can be applied, although I recommend not applying the treatment within 3 days of mowing. If any autumn lawn regeneration work is scheduled, then the autumn treatment will usually be applied at the same time, as it will be most beneficial when applied straight after a Scarification or Aeration treatment.
None of the standard fertilisation and weed kill treatments produce any waste that the customer needs to dispose of.
If a spot-herbicide has been applied with this treatment, then I recommend staying off the lawn for a couple of hours, until it is dry.
