A Simple Guide to Thriving with Peat-Free Compost

Gardening is Changing — And It’s a Good Thing

As gardeners, we’re always looking for ways to protect the planet while nurturing our plants. One of the biggest steps we can take is switching to peat-free compost. While it may look, feel, and even smell different from what you’re used to, your plants won’t mind — in fact, they can thrive in it when you make a few simple adjustments.

Why Go Peat-Free?

Peatlands are incredibly valuable to our planet. They act as carbon sinks, help combat climate change, and provide vital habitats for wildlife. By leaving peat in the ground and choosing peat-free compost, you’re actively contributing to a healthier, greener world.

How to Succeed with Peat-Free Compost

1. Choose the Right Compost:
Selecting the correct compost for your plant’s needs is key:

• Sowing seeds? Opt for seed and cutting compost.

• Potting or using containers? Use multi-purpose compost or one made specifically for containers and baskets.

• Improving soil? Try home-made compost or buy soil improvers or farmyard manure.

• Caring for house plants? Look for house plant-specific compost or mixes designed for cacti, citrus, orchids, or bonsai.

• Reducing weeds and water loss? Use bark or coir chip mulches.

• Growing acid-loving plants? Go for ericaceous peat-free compost.

👉 Tip: Always buy fresh compost each season and store it in a dry, cool space to keep it in top condition.

2. Water Wisely:
Peat-free compost often looks dry on top but can still be moist underneath. To check, stick your finger into the compost or lift the pot to feel its weight. If it’s still heavy or feels damp below the surface, you can wait before watering again.

3. Feed When Needed:
If you notice pale leaves, slow growth, or fewer flowers, your plants might need feeding. Start with a balanced, all-purpose plant food or a mild liquid feed from two weeks after potting.
