Step by Step Instructions

1 The difference between chemical and organic lawn care
2 Soil conditioners
3 Ground breaker for clay soils
4 Use a lawn spreader for chemical fertilisers
5 Water in the fertiliser using tonic
6 Use a soil wetter in summer
7 Fertilise twice a year
  • Step 1. The difference between chemical and organic lawn care

    There are two types of lawn care - chemical and organic. A chemical lawn builder gets instant growth and helps green up your lawn. Organic seaweed products are good for soil conditioning and fertilising.

  • Step 2. Soil conditioners

    A soil conditioner or health tonic won’t help with the growth, but it encourages a great root system. Strong roots hold water better and help your plants to thrive during the hot months.
  • Step 3. Ground breaker for clay soils

    A ground breaker is good for clay soils. It breaks down the soil and allows the water to get in. Mix it up in a watering can and apply to your lawn before you fertilise.

  • Step 4. Use a lawn spreader for chemical fertilisers

    When using chemical fertilisers, use a lawn spreader so you get a nice even coverage. This will reduce the burn patches if the chemicals build up and stay on your lawn too long. 

  • Step 5. Water in the fertiliser using tonic

    If you are going to use chemical fertilisers take the time to water it in properly after. It’s a good idea to use a seaweed concentrate with your water. Just clip the bottle to the end of your hose and you’re ready to go.

    Seaweed products are ideal for dry environments and help promote overall plant health. They help the lawn’s root structure develop and keep the moisture around the root source. 

  • Step 6. Use a soil wetter in summer

    Coming into summer it’s a good idea to use a soil wetter.  This will help hold the water around the root system in the hotter months.
  • Step 7. Fertilise twice a year

    Fertilise your lawn twice a year - once in the autumn months to protect it in the winter and once in spring to help boost the growth and carry you through the summer months.
