Learn what grows best in the EarthBox Root & Veg Gardening System, how to set it up, and which gardeners will benefit most from this self-watering planter.
Quick answer
The EarthBox Root & Veg Gardening System excels with deep-rooted vegetables like carrots, beets, and onions, but works well for almost anything you'd grow in a container.
Why the EarthBox works for root vegetables
The EarthBox's design — a self-watering reservoir with a wicking system — keeps soil consistently moist without overwatering. This is critical for root crops that rot in soggy conditions or become stunted in dry soil. The box is also deep enough (roughly 13 inches) to allow carrots and parsnips to develop straight, long roots.
What else you can grow
While the system is named for root vegetables, it handles tomatoes, peppers, leafy greens, and herbs just as well. The included aeration screen and fill tube make it easy to manage nutrients and water. For vining crops like squash, you may need a trellis or extra space outside the box.
Decision rules for choosing what to grow
- Root vegetables (carrots, beets, onions): Best choice. The deep soil and consistent moisture produce straight, tender roots. Thin seedlings to avoid crowding. Use a loose, sandy soil mix to prevent forking.
- Leafy greens and herbs: Excellent. Lettuce, spinach, basil, and chard thrive with less root depth. You can plant them closer together. Harvest outer leaves first to extend the season.
- Fruiting vegetables (tomatoes, peppers, eggplant): Good but need support. Use a cage or stake inserted into the box. The self-watering reservoir helps prevent blossom-end rot. Add a balanced vegetable fertilizer after the first fruit set.
- Large vining crops (squash, melons, cucumbers): Possible with a trellis. The box itself is not large enough for sprawling vines. Choose compact or bush varieties. Expect smaller yields than in-ground planting.
