July Blog

Well weather continues to be unpredictable , who would have thought that we would go through June with 2 inches of rain . This provided ideal conditions for newly sown lawns to thicken up nicely and also take the chance to re-seed some at the end of June in the hope that it would stay moist enough to enable germination . Well July has started with showers so you never know what you can get away with .

Even seeing some moss re-emerge on lawns where it had not quite cleared away from earlier iron applications to control it as the rain and warmth provide ideal conditions for re-growth.

Lot of fungi appearing in lawns this is due to warm weather in first half of June followed by wet weather and humidity  – nothing to worry about , not harmful and will disappear as soon as it drys out.

Also seeing a lot of Red Thread  – particularly on Fescue lawns , again common under the current weather conditions , the grass will grow out of it and only in really sever conditions is it worth treating with a fungicide , and it should really be as part of a planned approach where problems are know to exist

As we move in to July the expectation is that warmer dry weather will slow the release of fertiliser down, so we switch to using an Organic foliar feed to keep grass growing and looking nice and Green

We use a Symbio  product made from condensed molasses soluble by amino acid fermentation. Amino acids are the building blocks of protein and improve plant metabolism , sugars act as a bio stimulant for bacteria and the organic content acts as a fungal stimulant . Added to this is a Bio Tab, this benefits the soil micro-organisms , increases root mass, and converts thatch to humus improving water and nutrient retention.

In an ideal world this would be applied after aeration as it has a better chance of getting to where it is needed . Aeration reduces surface compaction and allow air and nutrients in to the soil which stimulates root growth. Aeration can be with hollow tine , in which case it is normal to top dress afterwards normally carried out early spring or autumn or solid tine that can be carried out all year round.

June – Blog

Better late than never  – well so much going on in such a short space of time.

May proved to be a cold month , but a wet month , remarkably it provided a great opportunity to re-seed lawns , and most came through looking pretty good , although some towards the end of May struggled a little when after one very wet Monday , the soil rapidly dried out at the surface capped making it tough on any seeds that were just pushing through the surface.

June till now has been generally warm , and lawns were starting to suffer again as they dried out so todays rains have been welcome. Its ironic that today I received a delivery of a compost additive that absorbs water and helps seeds to germinate  – wont be needing that for a week.

Ants have been running wild this June and I advise trying to rake the mounds they create in the first instance , this levels the soil out that they heap up and uncovers the grass so that is wont die back. If you don’t do this you will find the mower scalping these high points and leaving you bare patches. You can also try pouring cold water over the patch as ants are not supposed to like a bath , and then dust with an ant powder .

Many lawns have seen clover and trefoil spread this spring , the cold weather earlier on did not deter them and the dry weather suited them as they have a tap root and were able to grow away with out competition from the grass that struggled to make any growth. Both these weeds have relatively small waxy leaf area so when the weed killer is applied it struggles to stick to the surface , and as they are systemic we need the contact to allow absorption .

Weed grasses have also sprung up this year again due to the earlier colder weather  – many people have observed when looking down on their lawn from the bedroom window the green patches which seem to appear over night . At ground level it is not so noticeable , these weed grasses get into the lawns from wind dispersal , bird droppings , and may be were already in the soil. There growth habit tends to be horizontal rather than vertical , and when cutting the lawn you can end up just pushing them over which allows them to spread as some will send out roots from the leaf stems. Its worth trying to rake any patches you have before cutting the grass so at least they are standing up to start with.

As well as the straggling weed grass we also have the Poa annua  – annual meadow grass , seems to have the ability to grow any where , including the pavements and no matter at what height you cut it it manages to produce flower heads and seed .

One positive it that as we head towards the longest day of the year, and back into shorter days  grasses will stop trying to seed and revert back to vegetive growth.

Worst case scenario is to kill the patches off with a total weed killer and re-seed , or to even kill the whole lawn off and to start again. It is unfortunate how these unwanted grasses can change the overall appearance of the lawn  – at least if you re-seed , providing everything is killed off before you start you can be sure the new lawn will be from the seed in the pack.

May News

Well April was an incredible month , with many inquiries as to how lawns could be repaired or re-seeded etc I have to confess it was difficult to keep up.

Looking forward to May – weather forecast is for rain – but it remains to be seen how correct that will be, for the time being I would suggest that you continue to water where ever you can  – especially on areas that have been over seeded or scarified.

Its only due to the cold weather that lawns do not look worse – with out warm weather they have been growing very slowly , and so the lack of water has not stressed them as much as it could have.

Remember though not to cut them too short , lawns that are left with 3 inches will also be pushing roots down to find moisture . We are now starting to apply early summer treatments and will notify you when we are coming , please try to cut the grass before the visit .

Dry patch

What is really noticeable now are dry patches where the soil is unable to absorb water  – really highlighted during the dry spell as the grass there is dying off

Regardless of how much rain we often seem to get in the UK (and don’t we love to complain about it!), Dry Patch is a phenomena which happens to lawns when soil conditions have become so dry that water is no longer able to penetrate into the soil. This means that even when rain returns the soil has become hydrophobic – often this can occur in areas where there is high footfall or on the edges of lawns or mossy areas, where you have been exercising on the lawn during COVID and have compacted the soil or even around the washing line  . This is where surface compaction or lack of aeration , or moss has prevented water getting through and the grass is unable to make any root growth .

This condition often happens in lawns that have become old or where the soil is poor and natural healthy bacteria cannot work efficiently, the soil becomes dry and virtually dead with little or no active micro-organisms.

 

Hydrophobic conditions are caused by a white, waxy mycelium fungus in the soil which prevents any water from penetrating.

 

In some cases, the issue can be resolved by heavily hollow-tining the dry patches and applying a soil wetting agent, mixed with a fungicide. This process helps to break down the surface compaction of the soil so that it can absorb water and recover.

 

It may take repetitive treatments of wetting agent at monthly intervals to be successful, but in the worst cases, where treatment is likely to be unsuccessful, it will be necessary to remove the affected soil and replace it.

 

We need healthy soils to grow good grass , and that is where the benefits of cultural treatments such as our Symbio Bio treatments in the summer help by adding soil fungi and bacteria to keep the soil healthy.

 

Aeration and top dressing are so beneficial, but conditions must be right – its too dry for aeration on a large scale now – but it is the perfect time for focussing on those patches and giving them the specialist care they need.

 

April News

Just a quick catch up – this years weather is rather unusual and not helpful for lawns

  • February saw the end of the very wet winter – it was almost as if suddenly the tap was turned off.
  • March saw a little bit of rain , approximately 1 inch which was spread over the month in small amounts little and often .
  • April nothing in the way of rain – so much for April showers , it has been colder than March with the chilling winds although it has improved in the last few days.
  • The outlook is not much better with no rain forecast for early May.
  • These winds have also increased evaporation and dried the soil out and you can see areas of lawns that are susceptible to drying out starting to look pale.
  • We have also had a lot more frosts this month than I can remember for a long time and so many magnolias in full bloom have been hit – it has also kept soil temperatures down which is not helpful where grass seed has been sown and trying to germinate .
  • Its also too cold for the nematodes that we might have put down to control over wintered leather jacket

 

This cold dry weather means that herbicides applied to control weeds will not work so effectively , fertiliser will be released slowly as it is not moist enough , grass seed unless in contact with damp soil will be slow to germinate and lawns that have been scarified to remove moss will struggle to recover.

 

I have stopped all cultural work that was planned – scarification and aeration etc due to the dry,  this will be re-scheduled

 

March News

Never sure how many people get the opportunity to follow this

March has been a strange month so far starting off with relatively warm sunny weather – which resulted in many people venturing out and realising the lawns were not in the condition that they had hoped for .

Moss continues to be the devil – with many lawns heavily covered and going to need scarifying, which having done a few recently is taking twice as long as usual and producing a  massive amount of waste material

It also very noticeable that turf lawns have struggled , with grasses dying out  and there is no real pattern , some that were laid late in the year have really struggled , but then again some laid last April have not done any better . The one common thing seems to be that the finer grasses , the fescues have struggled and the stronger rye grass have survived.  Time will tell how well they recover , but most likely there is going to be a need for over seeding .

Having started warm – we seem to have reverted back to damp weather , and a cold wind – guess its what we should expect as we head towards the Spring equinox next weekend Saturday March 20th

Highlights the need for a regular plan and strategy to keep lawns looking good  – Not necessarily possible to fix things instantly but we can use the next few months to rectify the problems to have healthy lawns for future years
