Three systems working together —
the way nature intended

Most planters are just containers. The Garden Tower® 2 is a living ecosystem — growing, composting, and nourishing itself in a continuous cycle.

01
🌿

Vertical Growing System

50 large planting pockets arranged around a rotating tower. Grow nearly any vegetable, herb, or flower — tomatoes to basil, kale to strawberries. It rotates 360° so every plant gets equal sun.

02
🪱

Built-in Vermicomposting

A central tube runs through the tower. You add kitchen scraps — vegetable peels, coffee grounds, eggshells. Red worms convert them into rich organic fertilizer, directly feeding plant roots from the inside out.

03
💧

Closed-Loop Nutrient Watering

Water enters at the top and flows through every soil level, collecting nutrients along the way. What drains at the bottom is captured as "worm tea" — liquid gold you pour back in for a second pass.

A closer look at what's
happening inside

1

Central Compost Column

The perforated tube running through the center is where the magic starts. Kitchen scraps go in, worms do their work, and the resulting compost directly touches plant roots growing through the tower walls. In 9 months, a single Garden Tower can process over 50 gallons of organic waste.

2

5.5 Cubic Feet of Rich Soil

The tower holds 5.5 cubic feet of potting soil — far more than most container gardens. Internal horizontal shelves prevent the soil from compacting, so roots stay healthy for years. Most potting soils last 1–2 seasons in ordinary planters; in the Garden Tower, they last several years.

3

Top-Down Nutrient Watering

In a raised bed or container, over 90% of available nutrition washes below the root zone and is lost. The Garden Tower® captures this movement — nutrients flow from root zone to root zone as water descends, giving every plant a turn at the buffet.

4

Compost Gate & Nutrient Tea Drawer

Every 90 days, rich finished compost is released from the bottom gate for use elsewhere in your garden. The 2-gallon drawer below catches every drop of nutrient-enriched water that exits the tower — pour it back in for hydroponic-like growth rates.

5

360° Ball-Bearing Rotation

The entire tower rotates on an integrated bearing track — rotate toward the sun in the morning, rotate back in the evening. In tight spaces like balconies or patios, this means every plant gets full-sun exposure without needing a larger footprint.

Every detail considered,
every material chosen with care

Made in the USA from 100% food-grade HDPE plastic — the same material used in food storage containers. No BPA. No phthalates. No compromises.

50 planting pockets

50 Curved Planting Pockets

Generously sized, curved pockets make planting easy and remove root damage at harvest. Supports 200+ plant varieties from seeds to full-grown plants.

Ball bearing rotation track

Integrated Bearing Track

Effortless 360° rotation on a robust bearing track. Optimize sun exposure and tend to all your plants without straining or repositioning.

Compost gate

Seasonal Compost Release

Slide open the perforated gate every 90 days to collect finished compost. Kitchen scraps are reduced in volume by 10–20×, giving you concentrated garden gold.

Nutrient tea drawer

Nutrient Tea Collection Drawer

The 2-gallon drawer at the base captures all water exiting the soil — analyzed and proven to contain a balanced spectrum of essential plant nutrients.

Reinforced feet

Heavy-Duty Reinforced Feet

Wide, weighted, anchorable feet keep the tower secure on rooftops, patios, and decks. Survives winds over 70 mph. Optional caster kit for easy moving.

Made in the USA · 5-Year Warranty

UV-stable, food-grade HDPE injection-molded in the USA. Tested outdoors for 10+ years. LPC Petal Certified, Red List Chemical Free.

"Good food, less space"

This is my second garden tower and honestly I want a 3rd. You can grow so much in this attractive garden tower. The composter works great and keeps the plants healthy!

"It's brought me so much joy"

My bad knees, and the ability to rotate the whole tower have allowed me to sit and nurture my plant babies! I have one bean plant that has more flowers than a whole grow box. I am thrilled with my purchase!

Constance B. · Verified Buyer
★★★★★
"Fantastic in a limited space"

My two Garden Towers have served me very well as part of my urban driveway garden! The worms stay happy and cool in the center and have produced rich compost. Thank you for bringing gardening to those of us who inhabit condo land!

"Novice gardener's dream"

I've never planted nor gardened a single thing in my life. My garden tower is thriving! I've even got a happy worm ecosystem. I'm going to buy this as a gift for family at the holidays. Look at all the growth after only a month!

Bailey K. · Verified Buyer
★★★★★
"Best garden I've ever had"

I was worried about not having enough space, but everything is growing well. I used to have problems with rabbits eating my garden, but being raised up, it's not a problem anymore!

Ashley M. · Verified Buyer
★★★★★
"Master Gardener Approved"

Design and construction is excellent. They've thought of everything! Easy to assemble and maintain. Uses very little water. Plants and worms are thriving. I am thinking about getting another one.

Frequently asked questions

Worms are what make the Garden Tower® truly magical — they convert kitchen scraps into ready-to-use compost, aerating the soil as they travel and dramatically accelerating plant nutrition. You can run the tower without them, but introducing red wiggler worms (available separately) unlocks the full system. Most people find the worms become one of their favorite parts.
In cold climates, you can move the tower indoors or to a covered space. The surrounding soil insulates the worms from temperature extremes far better than a typical worm bin. Many customers overwinter their towers successfully in garages or enclosed patios.
The Garden Tower® supports 200+ plant varieties. Nearly any vegetable, herb, or flower works — from tomatoes, peppers, and kale to basil, mint, and strawberries. The only plants to avoid are large sprawling varieties like squash or pumpkin that need a lot of lateral space.
Just 4 square feet — a circle about 24.5 inches wide. It fits on a balcony, a patio, a rooftop, or a driveway. At 43 inches tall, it's about waist height at the lower pockets, which many customers with back or knee issues find a significant benefit over traditional gardening.
Very little. Water 3–4 times a week in peak summer (less in other seasons), add kitchen scraps when you have them, and rotate toward the sun as needed. Most customers say it fits naturally into their kitchen routine — scraps go in whenever they cook.
Setup takes about 30 minutes with no tools required. The planting rings stack and lock together. Many customers say it's one of the easiest products they've ever assembled — and the 2-minute assembly video on this page walks you through every step.
