The Arizona Worm Farm

Compost

We take compost seriously at our farm because well-made, properly finished compost is crucial for growing healthy, productive plants. That’s why ours takes six months to complete.

We only use naturally occurring ingredients — horse manure, food waste, basalt rock dust (to add mineral nutrients), and mulch from ground landscape waste. We take special care to turn the pile when the temperature reaches 130-140 degrees, allowing us to create a more fungal dominant compost.

Our compost is ideal for southwest gardens due to its water holding capacity, pathogen fighting ability, and nutrient delivery properties. Pair it with a sprinkle of our castings and a layer of our mulch for the perfect garden.

Pricing:

- U-Scoop screened compost: $3 per 5 gallon bucket (bring your own

container)

- Bag of screened compost: $10 (1.5 cubic feet)

- Bulk screened compost (pickup or delivery): $70/cubic yard*

Please note: To arrange bulk pickup or delivery please call us. Delivery fees are calculated based on the fastest route from the Farm to your address, one-way: $75 for 5-10mi, $85 for 11-15mi, and $6/mi for 16-30mi. Beyond 30 miles, premium pricing applies.

For pickup, standard pickup trucks can typically hold 1.5 cubic yards. We will do the loading for you.

Raised Bed Mix

Angela from Growing In The Garden custom designs this raised bed soil mix for southwest gardeners in Arizona's, often tricky, growing zones. She blends our six-month finished compost and worm castings with coco coir and coarse vermiculite for optimal water retention and basalt dust for mineralization. Add this ready-made blend in your raised beds or container gardens for the optimal mix of nutrients and water retention.

PLEASE NOTE: Effective 3/4/2021, COVID challenges at the Port of LA have made vermiculite unavailable. We will be using perlite instead of vermiculite until we can source vermiculite again. Your garden's performance should be essentially the same.

Pricing:

- Bag of Mix: $15 (1.5 cubic feet)

- Bulk (pickup or delivery): $150/cubic yard*

For pickup, standard pickup trucks can typically hold 1.5 cubic yards. We will do the loading for you.

HOW WE MAKE OUR MIX

Seed Start Mix

When starting plants, seedlings don’t have the same needs as established plants. When sprouts start, they prefer a light, fine-grained mix that promotes root growth over a dense, compact soil. Our Seed Start is a blend of coco coir, peat moss, perlite, AZWF castings, and insect frass. This ideal combination gives seedlings a loose soil structure with high microbial activity. It improves germination, reduces disease and damping off, and sets plants up for internal pest protection. Perfect for starting seeds or as a potting mix.

5 gallon box: $12

Mulch

Mulching levels soil temperature, helps prevent weeds and pests, enhances soil fertility, and conserves moisture. We offer sustainable mulch by sourcing hard and softwoods from landscape waste through the City of Phoenix’s landfill diversion program.

Our darker-colored, 3” minus screened mulch is perfect for landscaping or as a garden topper. Still, wherever your mulch ends up, you can feel good about diverting waste from Arizona landfills and contributing to healthy plant growth.

TO ALL MULCH CUSTOMERS:

Our mulch comes from a City of Phoenix landfill diversion program that is supposed to be plastic and debris free. They have not done a great job recently – so it will come with some plastic and junk. Before we send it out, we want to make sure you know what is coming.

Pricing:

- U-Scoop mulch: $1 per 5 gallon bucket (bring your own container)

- Bag of mulch: $5 (1.5 cubic feet)

- Bulk (delivery or pickup): $20/cubic yard for pick up & $30/cubic yard for delivery.

For pickup, standard pickup trucks can typically hold 1.5 cubic yards. We will do the loading for you.
