Did you know? Zone For All modular raised garden beds, borders, sandboxes, water gardens and accessories were designed by Anthony Topping, who founded the company. As a highly acclaimed landscape designer who for many years had designed high-end gardens in the New York Tri-State area, he felt there had to be a way to give homeowners the ability to easily create quality landscaping features and gardens for much less than paying a professional. 

Here’s a note from Anthony on why he designed this product:

"Articles describing English landscape design often feature stunning images of ‘Parterre’ Walk-Through Gardens, created by legendary landscape gardeners in bygone times. Elegantly beautiful in their geometric simplicity, they inspired me to design our selection of corner garden beds to create Zone For All’s Parterre Walk-Through’ Gardens. Small or large, they can be traditional or contemporary and easily assembled with two or more of our tool-free corner beds plus one or more island raised beds. If you divide your raised beds into square foot sections with a different plant in each (Square Foot Gardening), you will create a pattern that draws in the eye and adds contrast. The vertical height of the multi-level corner beds will ensure your design is space-efficient and provide for as much walk through space as you desire." - Anthony

THE FORT KNOX 8' x 8’ CORNER 2" RAISED GARDEN BEDS one level, are a triumph of form and functionality with 48 square feet of growing area for flowers, herbs, veggies, fruits, heathers or lavender.

With two FORT KNOX CORNER RAISED GARDEN BEDS and approximately 12' x 24' of lawn space it's easy to assemble a PARTERRE WALK-THROUGH GARDEN and create a focal point of enormous eye appeal. Set up the FORT KNOX 8’ x 8’ multi-level beds with their inner walls forming a Diamond shape between them. Add an ISLAND RAISED BED (Coming Soon) or create your own island garden with our Design App Tool in the space created - diamond, square, rectangular, oval or circular, leaving space to walk around and admire your garden.

Space permitting, with four FORT KNOX BEDS and two ISLAND BEDS you can replicate a formidably beautiful, traditional English Parterre Walk-Through Garden. Try incorporating a bench, garden globe or perhaps a water fountain for added beauty. Wow! Beautiful and functional, check out the illustrations.

Stunning as a flower garden and incredibly functional as a veggie garden you can plant annuals and perennials with vegetables. These multi –level beds feature dynamic angles and offer depth to plant potatoes or other root vegetables. Cherry tomatoes and ornamental peppers work well with flowers to encourage pollinating insects. Rhubarb, has lovely cream-colored flower stalks that fit in nicely with many plants. Once asparagus has faded, their feathery foliage adds special interest in a flower border.

Check out Plant, Friends and Enemies to mix and match your plantings and be sure to plant complimentary plants. Veggies including artichoke, arugula, asparagus, lettuce, pole beans, beets, carrots and cabbage will all thrive in this raised garden bed, together with luscious tomatoes, fragrant herbs and flowers. For easier harvesting, leave sufficient space on all sides making it super-easy to run out and pick veggies for a salad.

Tool-free snap-lock joints make it simple to install. Your kit comes with everything you need other than soil and plants. Each modular kit includes food safe, 2" straight composite boards and 2" snap-lock stacking brackets. The insulating open-channel boards trap air, providing insulation to your soil, keeping soil warmer in the spring and fall, and cooler in the summer to extend the growing period.

Stacking brackets allow you to install the additional layers of your garden just by inserting the stakes into the brackets below. Our patented snap-lock brackets simply slide onto each end of a board and fasten securely with snap-lock buttons. Brackets pivot 270 degrees, allowing endless design options. As your garden needs and expertise grow you can add on to your modular raised bed any time by purchasing additional tool-free kits, boards and snap-lock stacking brackets to stack or extend your garden.

Include a Zone For All Worm Box to this deep raised bed to create a composter by adding chopped leaves, grass clippings, semi-rotted compost and mealtime left-overs to the soil to attract earthworms to take up residence, be active and thrive.
