These seeds should ideally be sown this season. All our packets have ‘Sow by Date’ guidance on them, this is the date the seeds should be sown in order to achieve the highest rate of germination. You will still see the same high-quality plants if sowing in seasons after the ‘Sow by Date’ but may see a reduction in germination rate

Description

Loved by our gardeners for its versatility and effectiveness, Organic Extra Fertiliser is your go-to solution for boosting the health of your entire garden. Whether you're tending to fruits, vegetables, flowers, or plants, this powerful, all-natural fertiliser works wonders across your garden beds.

Our customers rave about its ability to improve soil quality while delivering long-lasting nutrition that won’t scorch or damage your plants. Our customers rave about its ability to improve soil quality while delivering long-lasting nutrition that won’t scorch or damage your plants, with plenty of 5-star reviews to back it up.

Sufficient to cover a 23ft by 7ft (7m x 2m) plot up to 30 times. That's less than £1 per use, providing year-long nourishment for all your crops!

  • Acts as a fertiliser and soil improver: Packed with organic nutrients, it steadily releases them over time, enriching your garden with essential nourishment.
  • 100% organic and peat-free: Made from farmyard manure with added seaweed extract, it provides a rich, natural boost without harmful chemicals.
  • Safe and gentle: Unlike fresh manure or harsh chemical fertilisers, Organic Extra won’t scorch your plants.
  • Multi-purpose: Use it across your garden for everything from vegetables and fruits to flowers and houseplants.
  • Super-concentrated: Only a few handfuls per square metre are needed, making it cost-effective.
  • Seasonal benefits: Ideal for autumn to replenish nutrients used over the summer and again in spring to replace nutrients lost over winter.

Organic Extra also acts as a natural slug deterrent, giving you peace of mind!

How to Use:

  • For general garden use: Sprinkle a couple of handfuls per square metre of soil around your plants and gently rake in. Water well to activate the nutrients.
  • For potted plants: Use a small handful per pot, mixed into the compost, and water thoroughly.
  • As a liquid feed: Soak Organic Extra in water to create a liquid feed. Simply mix a few handfuls with water, leave for a couple of days, then strain and use the liquid to water your plants.
  • Seasonal application: Apply in autumn to boost nutrients ahead of winter, and again in spring to promote healthy plant growth after the cold season.
