How to Choose the Right Compost for Your Plants
Not all composts are created equal! Here’s a quick guide to help you pick the perfect mix:
Seed Sowing – Choose a fine, free-draining seed compost to encourage strong germination.
Potting On – Use No. 1 or No. 2 John Innes compost for young or maturing plants.
Houseplants – Go for specialist peat-free mixes tailored to the needs of tropicals, succulents or orchids.
Fruit & Veg – Use nutrient-rich, multipurpose compost or topsoil blends for strong yields.
Established Plants – Try John Innes No. 3 or a slow-release formula for long-term support.
Making Your Own? – Compost bins and compost makers make it easy to recycle organic waste into garden gold.
Top Tip - Keep your compost in a cool, dry place to retain nutrients and structure until you’re ready to use it.
