Lawn Care in Hertfordshire

With summer comes a lot of lawn challenges - from sod webworms, chinch bugs, nutsedge to drought stress, diseases and lots more. A lot of people find it hard to tell what’s happening to their lawn and probably assume it to be as a result of the summer stress and will definitely turn green again once the fall rolls in. This may be right in certain situations, but if you have fungi eating deep into your lawn, the green may not return. So, how exactly do you figure out if your lawn has diseases or pests? In this post, we’re going to provide you with a good insight into this to help you take the necessary treatment steps as soon as possible.

• Fungal structures. Fungi structures are not usually the easiest to spot as they vary in shape, colour and appearance. Fortunately, most fungi that appears on lawns will possess some type of structure which can be spotted when moisture is present. Once the night time dew sets in, you’ll be able to identify these strange growths in your lawn.
• Matted or Collapsed Areas. There is some sort of diseases that will make grass plant to wilt in little time. This, combined with fungi structures will make the grass look to have been matted in some areas.
• Discoloured or oily areas. Some areas are likely to show symptoms more than the others. While the unaffected turf may remain in its normal state, areas that are nearby may vary in colour due to the damage to the leaf tissue.
• Lesions or spots on leaves. Do you notice a certain damage pattern on the leaf blades of the grass plants? If yes, then your lawn is probably infected with a disease. Some of these spots may vary in size and colour.

Moss, mushrooms and weeds are all problems that many homeowners face on their lawns. Luckily, with a bit of maintenance, there are ways you can get rid of these unwanted organisms and prevent them from coming back. Getting rid of moss A simple way to remove moss from your lawn is by scarification. This basically means that you vigorously rake your lawn, but only do this in the autumn when the grass is actively growing and it’s not too hot, cold or dry. However, you can also use specific weedkillers to control moss on your lawn, and most of these should be applied when the moss is actively growing. Apply in fine weather by hand or with a push-along spreader, making sure not to apply too much as you could kill off the grass too. Check the instructions, as some will require watering after 48 hours if it’s not rained. Then, get into a scarification routine to help prevent moss growth. Removing mushrooms from your lawn If you’ve got mushrooms in your lawn, it usually means that your lawn is damp and shaded, so it never dries out, and is organic waste-rich. There could be a drainage problem with your lawn that is encouraging mushroom growth, so it’s important to investigate why the mushrooms are growing to prevent them from returning once you’ve removed them. To get rid of mushrooms in your lawn, make sure you scarify your lawn and get rid of all the moss, thatch and dead grass that comes up. If you leave it, this is heaven for mushrooms to grow in. If your lawn is shaded, try to prune and thin surrounding trees to offer it more light. If you do all of these things, it will prevent mushrooms from growing in the future, and then it might be worth using a fungicide to get rid of the mushrooms that are there. But if you just do this step, it’s likely the mushrooms will just come back. How to get rid of weeds To get rid of weeds from your lawn, you can use selective weedkillers that will just kill the weeds and leave your grass alone. But if you’d rather not use weedkiller, you can get rid of weeds from your lawn manually. For large, deep-rooted weeds like dandelions or plantains, use a trowel to lever them out, ensuring that you get the whole plant including its roots. Then use compost to fill the hole it leaves behind, pushing it deeply into the hole. Sprinkle with fresh grass seed, cover with extra compost and water. Make sure you keep the area damp until the seed has germinated. To prevent moss, mushrooms or weeds from returning, the best things to do are:

• Scarify your lawn in the autumn, and lightly in the spring if necessary
• Seed your lawn in the autumn if you need to
• Try to keep trees trimmed and pruned as much as possible to reduce shade
• Use a pre-emergent weedkiller in the spring to catch them before they grow and handpick any that come through
• Mow your lawn regularly in the spring and summer, being careful not to remove more than a third of grass at a time, then before winter give it one last mow and a fertilisation treatment

Overseeding your lawn is an essential part of keeping your lawn looking its best. It’s also known as reseeding, and helps to repair damaged areas that might have been caused by a harsh summer or winter. It’s best to overseed your lawn during the spring or autumn, when the temperature is mild but there’s still a fair amount of rainy days to help the grass seed grow. To prepare your lawn for overseeding, you should do the following things around 1-2 weeks beforehand:

• Weed the lawn by hand or using a weedkiller (make sure you leave enough time to do this according to the instructions)
• Remove stones and large twigs
• Scarify your lawn to remove moss and loosen soil
• Fertilise the soil with a quick-release fertiliser

Once you’ve taken these steps, you’re ready to start overseeding your lawn.

1. Mow your lawn to around 25mm in length.
2. Water the soil so it’s moist but not too damp.
3. Sprinkle your new grass seed evenly over the lawn, but apply more in patchy or thin areas. Generally gardeners say to use 35g per square metre, but up to 50g on thin areas.

When you’re finished, give your lawn a final water, and do this every day until the new grass is established – particularly if it’s not rained. Just make sure you don’t overwater it. It’s also a good idea not to walk on your lawn for around 2-3 weeks after you’ve overseeded it.

Scarification is the name given to the process where you remove excess thatch and moss from your lawn to encourage it to grow and look healthy. Although it sounds difficult, it’s actually pretty easy – simply grab a sturdy rake and apply moderate pressure to rake out moss, thatch and dead grass. Then collect it up and add to your compost heap if you have one. You can also use a petrol or electric rake, but you just want to tease out the moss and thatch. Don’t be tempted to go deep into the grass, as this could damage your lawn. So when should you scarify your lawn? The experts say that the best time is in the autumn, when the grass is actively growing and it’s not too hot, cold or dry. Most of summer’s weed seeds will have gone, so you won’t encourage weeds to grow in the raked-up soil. This soil also makes an ideal seed bed for over seeding with new grass seed, so that’s why you don’t want to get weeds in there as well. However, you may also carry out light scarification in the spring – usually around April. Make sure you don’t go too far though – as you will end up with a rather disfigured lawn if you scarify too heavily and the dryness of summer stops the lawn from recovering. It’s also best to scarify your lawn in the spring if the following apply:

• If you couldn’t do it the previous autumn – if you keep putting it off, you might end up with extreme moss and weed growth
• If your lawn is shaded – these areas will thin over winter and start to thicken from spring onwards, so if you scarify in the autumn you’ll make your lawn even thinner.
• If your lawn is under trees – pair the shade from the trees with the fall of leaves in the autumn and your grass won’t be healthy, but in the spring the trees are bare, allowing lots of light onto your lawn to help it grow.
