Q. What’s the best way to get rid of moss?

A. The first step is to identify and rectify the cause of the moss problem.

  • Excessively shady – If possible prune overhanging foliage to improve light and airflow to the lawn.
  • Acidic Soil – Test soil and if required increase the pH with garden lime.
  • Waterlogged Soil – Reduce compaction, aerate soil or in extreme cases add drainage.
  • Poor Grass Nutrition –Start regular application of lawn fertilisers (for example Aftercut All-In-One*)

The Second step is to treat and remove the moss that is currently in the lawn. To do this a moss killer would need to be applied across the lawn, the most common type are based on Iron (Ferrous) Sulphate. Once this has been applied the moss will blacken and die over a week or two, depending on the conditions in the lawn. The moss should be raked (scarified) out once dead and if required the lawn can be over seeded with a high quality lawn seed to help it thicken. *Use Pesticides Safely. Always read the label and product information before use.

Q. How do I get rid of dandelions?

A. Dandelions (Taraxacum officinale) are easily identified by their distinctive shape and yellow colour. Deeply rooted, this weed tends to flower early and seed prolifically. Even the most cared for lawn will get the occasional dandelion growing from most likely a wind-borne seed. One of the easiest method methods to keep them under control is to keep them mown, so they cannot spread. For a non-chemical control carefully dig out the weed making sure to remove the whole taproot please note that if the root snaps off in the ground then it will most likely grow back.

A selective weedkiller for use in lawns (for example Resolva Lawn*) will be the most useful option. This weedkiller is based on plant growth hormones, and will force the weed to grow until it dies. Therefore after application you should see the weeds becoming larger and greener until they die (4-6 weeks later). As plant hormones differ in broadleaf weeds such as dandelions and grasses, the weedkiller will not kill your lawn. *Use Pesticides Safely. Always read the label and product information before use.

Q. How can I stop my dog from ruining my lawn?

A. Although large dogs sometimes rip patches of the lawn up, the main source of damage comes from dog urine. The urine has essentially concentrated nitrogen in it, which scorches the grass.

The best method is to dilute the problem, tip water onto the lawn where the dog has been to wash through the urine to prevent any scorching. Another option is to keep the moisture up in the soil by watering the lawn regularly. Also keeping the lawn well fertilised and cared for can help to make the lawn more resilient.

If you already have patches, Aftercut Patch Fix will help to resolve the problem, as it has been formulated to help neutralise pet urine along with using resistant grass varieties. To fix patches follow the steps below:

  1. Remove weeds, moss and debris.
  2. Loosen the bare soil surface with a rake, breaking up any large lumps or compacted soil until it has a fine crumbly texture. You may need to add some Gro-Sure Lawn Seeding Soil or Lawn and Turf
  3. Dressing to prepare the area.
  4. Scatter Aftercut Patch Fix evenly over the area to 2mm depth. Add a little more to the surrounding lawn to ensure that the patches blend in with the existing grass better. Water thoroughly.
  5. Continue watering in the evenings, until the grass is 7-8cm tall. Lightly mow on a high setting.

Q. What’s the best type of grass seed for my garden?

A. The type of grass seed to use depends on the conditions of your lawn and its intended purpose. Firstly for a general lawn, a multipurpose lawn seed would be ideal eg. Gro-Sure Smart Seed or Multipurpose Lawn Seed. These seeds are a blend of dwarf perennial rye grasses and fescues to give a good all round lawn. Fast germination blends are also available in the form of Gro-Sure Fast Acting Lawn Seed.

For an ornamental lawn a finer blade may be required. Gro-Sure Finest Lawn seed, which is a blend of fescues would be suitable. This type of lawn would not stand up to heavy traffic or shady conditions.

For more specific conditions eg. shady lawns, high wear and tear lawns, both Shady and Tough lawn seed blends are available.

All our seeds have a bird deterrent coating to maximise your success.

For best results, sow in the spring from March to May, or in early autumn, from mid-September to mid-October, depending on weather conditions.

Q. How can I keep my lawn looking great all year round?

Springtime – Start mowing with caution. Don’t be tempted to cut if your lawn is very wet, or if there is frost of snow on the ground. Be gentle with the first few cuts of the season and simply trim with the mower blades adjusted to their highest setting. Apply a lawn, weed, feed and moss killer, such as Aftercut All in One. If your lawn is very compacted, consider removing plugs of soil using a hollow tine aerator to improve drainage. After the lawn has been aerated, fill the holes throughout the season using Aftercut Lawn Thickener.

Summer – Summer time is the best time to enjoy the lawn but it can also have the biggest toll on your grass. Persistent hot and dry weather can quickly affect the appearance and overall health of your grass, so moisture is key! Mow regularly You will now probably need to increase the regularity with which you mow your lawn. If the conditions are ideal for growth, you may need to cut twice a week to keep it looking good. Don’t be tempted to cut the lawn too short when it is hot as this can cause damage. If you are going away on holiday, cut the lawn normally as close to your leaving date as possible. Use an edging iron to keep lawn edges neat and tidy. Apply a feed to keep your lawn looking green and healthy. Aftercut 3 Day Green can be applied directly after mowing and can be used every 3 to 4 weeks until October.

Autumn - Autumn is a critical time in the lawn care calendar. There’s lots you can do to prepare your lawn to make it through the difficult winter months and it’s also a great time to sow a new lawn. Sweep up autumn leaves using a rake. This is really important as if left on the lawn, the leaves will rot down on top of the grass, causing damage and releasing pathogens, which could cause disease. Adjust the setting on your mower. As the weather starts to change, the grass will be growing much more slowly. Adjust the cutting height on your lawnmower so that it cuts the grass higher. Treat weeds and moss. If the lawn is very mossy, treat with Aftercut Autumn All in One which is specially formulated for the colder autumn months. Autumn is an excellent time of the year to sow a new lawn from seed. The soil is still warm from the summer and the autumn rain will provide vital moisture as the new lawn develops. It is vital to prepare the soil thoroughly and to keep the developing lawn properly watered.

Winter - It’s essential to keep foot traffic to a minimum and to keep an eye on the growth of the lawn. Use the winter months as a time to plan and prepare for the season ahead. If your garden needs a new lawn, plan it out over the winter, so that you are ready for action when the warmer weather arrives. During the winter your lawn should stop growing and therefore will not require mowing. Periodically sweep up fallen leaves and any debris, but be careful to keep foot traffic to a minimum as this could damage your lawn. Look out for water puddles on your lawn after heavy rain, as this is a sign that the soil is compacted and will benefit from aerating later on in the spring.
