Worms do not fix bad soil.

They establish and multiply only when the environment suits them.

If the conditions are right, they will survive, breed, and spread.
If not, they will disappear.

The goal is not just to add worms — it’s to create the right conditions for them to thrive.

Before introducing your Soil Builder Worm Mix, check for:

Moisture
Soil should feel like a wrung-out sponge — damp but not waterlogged.

Temperature
Active above 10°C.
Ideal range: 15–25°C.

Oxygen
Loose, aerated soil or organic matter.

Organic matter
Mulch, compost, leaf mould, or plant residues.

pH
Neutral to slightly acidic soils (roughly pH 6–7.5).

What to expect after adding worms

First 2–4 weeks
Worms settle in and begin building burrows.

1–3 months
Soil becomes easier to dig and more crumbly.

6–12 months
Visible worm casts, improved drainage, and stronger plant growth.

Worms work slowly but permanently.

1. Prepare the soil
   Add compost, leaf mould, or mulch.
2. Dig small holes
   3–4 holes per bed or per square metre.
3. Add Garden Worms first
   They will head deeper into the soil.
4. Add Composting Worms on top
   They live in the upper layer.
5. Cover and mulch
   Replace soil and add a thick organic mulch.
6. Water lightly if dry
   Keep soil moist for the first few weeks.

Keep them happy

• Maintain a mulch layer on the surface
• Keep soil moist, not waterlogged
• Avoid synthetic fertilisers and harsh pesticides
• Keep living roots in the soil as much as possible

Bare soil is a worm desert.

Provenance (transparent and important)

• Composting worms are a native species mix selected for composting ability.
• Garden worms (Lumbricus terrestris) are a native species.

For the global market, these worms are produced in large, stable populations in Ontario, Canada, mostly for fishing worms.

We source them in the UK - they are provided with plant-health certification, transferred to us in a sterile carrier, and packed fresh on our farm.

From our farm to your soil

At Lower Blakemere Farm in Herefordshire, worms drive our composting systems, manure breakdown, and regenerative soil building.

Every order helps support soil health, wildlife, and regenerative farming.

Wiggly Tips

• Bare soil is a worm desert — always mulch.
• Add compost little and often.
• If beds dry out, soak and re-mulch.
• Feed the soil food web, not just the plants.

Quick FAQs

Will the worms stay where I put them?
They’ll move to wherever conditions suit them best. Good mulch keeps them close.

Do I need to dig them in deeply?
No. Just place them into small holes and mulch well.

Can I add more compost later?
Yes — that’s exactly what keeps the system thriving.

When is the best time to add worms?
Spring or autumn, when soil temperatures are between 10–25°C.

Are the worms safe to introduce?
Yes. All worms are supplied under plant-health certification and packed in sterile bedding.

How quickly will I see results?
Most people notice improved soil texture within a few months, with bigger changes over the first year.
