Our Indoor Herb Compost is handcrafted here in the UK and comes in a resealable bag, meaning that you can always use it later if you have too much. It'll also stay fresh for at least twelve months once opened, so never worry about it going off shortly after purchase. We formulate the soil ourselves and keep it in quarantine for 14 days to ensure there are no soil-borne pests like Fungus Gnats.

Don't know the size of your new pot yet? Simply measure the pot's top diameter to find the perfect amount of compost you'll need for repotting.

Size (Litres)Ideal for...
1L13cm pots or smaller. Perfect for sowing seeds, too!
5L15cm - 20cm pots
10L24.5cm - 30.5cm pots, or larger containers like troughs/planters

Checklist for a Successful Repotting:

  • Ensure the new pot has drainage holes in its bottom. No matter how good a compost is, you're always running the risk of root rot if water begins to accumulate in the pot's base.
  • Respect the roots. 'Transplant Shock' is a common issue among heavy-handed transplants, so always be delicate and try not to over-touch the roots or pull soil from them. You can always book a 1-1 Video Call with Joe Bagley if you're worried about transplantation. 
  • Fill the new pot a fifth-deep with the new potting mix. Sit the plant on top of the mix and fill the gap between the pot and roots. Instead of patting down the compost for support, simply give the plant a thorough soak with water to consolidate its new soil. Wait until the drainage holes finish dripping water before placing it in your decorative pot. Job well done!

Seed Sowing

  1. Fill a 7cm plastic pot with your Indoor Herb compost and water it thoroughly. It's best to do this outside to avoid spilling compost-water everywhere!
  2. Re-spread the compost to flatten it out and spread the seeds across, making sure they have at least a 4mm gap between them. 
  3. Sprinkle the vermiculite that we've sent over the soil to lock-in the moisture and place the pot(s) on a north or east-facing windowsill away from radiators. Keep the soil continuously moist and wait for new growth to emerge!

This product comprises individually-sourced components to create our quality potting mix. Its basal component, the peat-free soil, is sourced from two well-established companies both in southern England and Northern Ireland that comply with strict garden waste management and production regulations in the U.K.. We then combine the two soil components on-site before adding the perlite, grit and biochar to improve the overall soil structure and replicate the ecological habitats of temperate and tropical climates.

All our products include recyclable packaging/materials, with deliveries made to the local Post Office or parcel depot via fully-electric transport. Our commitment is to provide good quality potting mixes to customers without causing harm to the local and wider environment.
All of our composts come in a resealable bag, so never worry about having a little extra left over. Simply enclose the lid and situate it in a dry, dark area away from pets and children. The soil's freshness will last at least twelve months once opened, so it's great for emergency repotting and top-ups.
Unfortunately, our handcrafted composts are only available to those in the U.K., due to E.U. trading laws on plant-based materials. However, if you are in the U.K., expect free delivery and postage within three days of purchase! 
Due to the weight difference when containing water, most soil are measured by the volume. Most companies (like ourselves) will go down the route of Litres, with only a few using other methods like the size of their bags/sacks. We use Litres to help the customer visually imagine the amount that they'll receive!
Any good compost will only hold a certain volume of water before dripping the excess through the drainage holes. With this in mind, you're most likely going to cause root rot by watering the plant too often instead of the exact amount of water per drink.

Here's an example. It's far better to water the plant 7L in one go once a week, as supposed to 1L per day for the entire week. The roots won't be able to access the oxygen within the soil, which is critical for reducing the development of root rot. Like bubbles in an ocean, the air will rise when the potting mix is wet, so it's essential to allow the soil to dry slightly between drinks to regain the oxygen.

Our Repotting Kits are designed to maximise both the air circulation and soil structure around your plant's roots, meaning that it'll have the very best conditions for optimal growth. Remember not to water the soil too frequently, and your little friend will very much enjoy his new home!

We'll send you a confirmation email with the purchase's receipt, along with a Step-by-Step Guide on repotting/sowing the seeds. You can then refer to the guide once your compost arrives! 😊
