Botanical Bento Box Salsa Garden (Part 1)

My botanical bento salsa garden plan

But for many of us in Zone 8b and up, the challenge isn’t the climate; it’s the space. Between the garden shed, the patio, and all the outdoor “stuff” stored for the past season, a sprawling “homestead” garden is often a luxury we don’t have.

Botantical Bento Trend

Enter the Botanical Bento Box Garden.

I ran across this last autumn in one of my feeds touting it as one of the big garden trends of 2026.

Inspired by the Japanese partitioned lunchbox, the Bento Garden is a philosophy that combines extreme organization, high-density organic planting, and aesthetic balance. It’s the opposite of my traditional “survival of the fittest” chaos backyard plot, focusing instead on a curated, modular system where every square inch has a job to do.

By dividing the growing space into “compartments,” you can maximize your yields, simplify your organic pest management, and create a garden that looks as good on Instagram as it tastes on the dinner table (or so the article says).

The section of the keyhole garden that will become the bento box

Intrigued, I decided to try it out using a roughly 3 foot in diameter section of my keyhole garden that’s currently empty.

Southwest Salsa Bento Garden

Because we’re planting densely in a small space, container variety plants are ideal for the garden bento box. While you can go with flowers or pretty much any curated combination of plants, it just so happens that I have several packages of container variety vegetable seeds perfect for a mini salsa garden courtesy of a friend.

The container varieties going into my bento salsa garden (L-R): cheery tomato, jalapeño peppers, bunching onions, and cilantro

I started these in my greenhouse back in early February, so now they’re almost ready to move into the keyhole garden. Here’s what I am planting:

The “Base” “Litt’l Bites” Cherry Tomatoes

Tomatoes are the anchors in a good salsa and, according to the package this variety will produce tons of snack-sized tomatoes from early spring all the way to first frost in autumn. Litt’l Bites are a window box / small pot variety that grow to about 12 inches high and up to 20 inches across, so I’ll be planting 4-6 of these, clustering them in half of the garden nearest the compost bin where they’ll pick up extra nutrients and be easy to pick as they ripen.

The “Heat” Early Flame Jalapeño Peppers

Another container variety, these grow a medium hot pepper around 3 inches long on the top of tall (20-24 inch), but compact plants. I’ll be planting 6-8 of these if they’ll all fit in their own little wedge.

The “Cool Spice” Longstanding Cilantro

While not really a container variety per se, this cilantro does stay relatively compact even after flowering. Why I’m really planting it is that cilantro really hates our San Diego heat and bolts by late spring. Longstanding is a heat tolerant variety hangs on considerably longer than others, providing fresh cilantro all the way into late June. Since we harvest this as it grows, I’m planting a dozen or so in a wedge.

The “Crunch” Evergreen Bunching Onion

Bunching onions are milder than other varieties, but you can start harvesting the greens substantially earlier than large onions. Additionally, they really don’t take up any space horizontally, so I’m going to plant as many as I can around the entire border of the bento box. I figure I can squeeze between 48 and 60 of these little onions into the garden, which should be more than enough for salsa, as well as salads and snacking (one of my wife’s favorites).

Maximum Garden, Minimum Space

The seedlings waiting to be transplanted outdoors

While this garden is only slightly more than 7 square feet, if the rumors about the efficiency of the botanical bento garden are true, gridding it this way should allow me to harvest substantially more than a standard row arrangement. If it works, I think I’ll try a flower garden variant of this using a cluster of different sized pots too.

Of course, only time will tell, so stay tuned for updates.
