Yes. JoeBees is completely free to use, with no account required. Plan a raised bed, ask the AI gardening tutor questions, and print a take-outside sheet at no cost.

How big should my raised garden bed be?

A 4×8 foot raised bed is the most popular starter size. It gives you 32 square feet — enough for a varied salad, herb, and tomato mix — while staying narrow enough to reach the center from either side without stepping into the bed and compacting the soil.

What is square-foot gardening?

Square-foot gardening, popularized by Mel Bartholomew, divides a raised bed into 12-inch squares and assigns each square a set number of plants based on their mature size. JoeBees uses this method to maximize yield per square foot while preventing crowding and root competition.

Does JoeBees support companion planting?

Yes. JoeBees flags antagonistic pairings placed too close together and groups proven companions automatically. The AI layout tool also accounts for spacing, sun exposure, and your USDA hardiness zone.
