🌿 Why Spring Lawn Feeding Matters
During spring, grass moves out of dormancy and begins active growth. Spring fertiliser:
- Encourages lush, vigorous growth
- Helps repair winter damage
- Improves colour and density
- Reduces weed and moss competition
Feeding too early or with the wrong fertiliser can do more harm than good.
🧪 What Nutrients Lawns Need in Spring
Lawn fertilisers are made up of three main nutrients:
- Nitrogen (N) — promotes leaf growth and green colour
- Phosphorus (P) — supports root development (often limited in UK feeds due to regulations)
- Potassium (K) — helps stress resistance and overall hardiness
In spring, higher nitrogen is key to jump-starting growth.
Typical good spring ratios:
👉 High nitrogen, moderate potassium; phosphorus only if soil-tested deficient.
🍃 Types of Lawn Feed for Spring
1. Standard Granular Lawn Fertiliser (Balanced or Nitrogen-Rich)
Ideal for most lawns.
✔ Easy to apply with a spreader
✔ Feeds steadily over several weeks
✔ Encourages green growth
👉 Look for feeds with emphasis on nitrogen (e.g., NPK like 15-5-10).
Best for: healthy lawns needing a growth boost.
2. Slow-Release Lawn Fertiliser
Releases nutrients gradually over 6–8 weeks.
✔ Reduces risk of scorch
✔ More even growth
✔ Less frequent feeding
Best for: lawns that grow fast or are fed regularly.
3. Liquid Lawn Feed
Fast-acting but shorter-lasting.
✔ Quick colour and growth response
✔ Good for early spring when soil is cool
Best for: immediate boost before granular feed.
4. Organic Lawn Feed
Made from natural ingredients like seaweed, composted manure, or feather meal.
✔ Improves soil life
✔ Gentle feeding
✔ Slow, steady result
Best for: eco-friendly lawns or soil improvement.
🕐 When to Apply Spring Lawn Feed
Best timing:
- Early to mid-spring — when soil begins to warm
- After first mow (remove debris first)
- When growth signs return
Avoid feeding when soil is waterlogged or frost is likely.
📍 How to Apply Lawn Feed
Granular:
- Spread evenly using a spreader
- Water in if rain isn’t expected
- Avoid overlapping passes
Liquid:
- Mix according to label instructions
- Apply with sprayer or watering can
- Water lightly after application
Consistency matters more than quantity.
💧 Aftercare After Feeding
- Mow at a normal height — don’t scalp
- Water during dry spells
- Overseed thin patches after feeding where needed
Feeding works best when combined with good lawn care habits.
❌ Common Spring Lawn Feeding Mistakes
🚫 Feeding too early in cold weather
🚫 Applying too much nitrogen
🚫 Fertilising waterlogged soil
🚫 Skipping correct application rates
🚫 Mowing immediately after feeding at very low height
Too much too soon can burn grass or encourage weak growth.
🌟 Final Thoughts
The best lawn feed for spring is one that provides a boost of nitrogen to jump-start growth without overwhelming the lawn. Whether you choose standard granular, slow-release, liquid, or organic, timing and correct application make all the difference.
Feed when the lawn starts growing, keep it moist, and combine with mowing and overseeding for a healthy, lush spring lawn.
