Spring Surge Pro

All our fertilisers are designed to be applied at 25g per m² — the perfect rate for professional results without the risk of overfeeding.

You might be used to heavier application rates with DIY products, but our formulas are concentrated, so a little really does go a long way.

To work out how much you need:

• Measure your lawn using our handy Lawn Size Calculator.
• Multiply your lawn’s size (in m²) by 25g
• Choose the pack size that covers your area — if you’re between sizes, round up to ensure full coverage.

Bag coverage guide:

• 50m² bag = 1.25kg
• 100m² bag = 2.5kg
• 200m² bag = 4.7kg

Stick to 25g per m² and you’ll see fast, safe, and visible improvement.

Follow these simple steps for best results:

Step 1: Mow your lawn (if needed)
For best results, mow your lawn 2-3 days before applying fertiliser. This clears away excess grass, helping the nutrients reach the soil where they're needed most. Avoid mowing immediately before application, especially in very dry conditions, as freshly cut grass can be more prone to stress.

Step 2: Measure the correct amount
Use our Lawn Size Calculator to work out your lawn area. Then weigh out 25g per m²  (kitchen scales are useful for this). It might not look like much, but it's the perfect amount for our high-performance fertiliser. Please don’t be tempted to add more — applying too much can over-feed your lawn, leading to potential damage or scorching.

Step 3: Spread evenly
Apply the fertiliser evenly across your lawn using a handheld or push spreader. Walk at a steady pace in straight lines to ensure consistent coverage. Need a spreader? Shop our handheld spreaders.

Step 5: Wait before mowing again
Hold off mowing for at least 3 days after application and watering to allow the fertiliser time to fully absorb into the soil. This gives the nutrients the best chance to take effect.

Step 6: Children & pets
The lawn is safe for children & pets to walk on immediately after application. However, do not allow pets to ingest granules or to eat any grass until the fertiliser is fully watered in and the grass is dry. See our Child & Pet Safety Guide for full advice.
