Placement
This is a planting guide, not a build. Set it where all sides get sun, or put it on a dolly so you can move it instead of rotating an 80–120 lb tower.
Parts to Buy
| Part | Quantity | What You Use Them For |
|---|---|---|
| Vertical garden tower or strawberry planter | 1 | Planter body — buy one or build the strawberry tower from this site |

- ·Optional: drip irrigation emitter for the top
- ·Optional: plant labels
- ·Optional: dolly or wheeled saucer if you need to turn the tower for sun
Steps
- 1Start with a pre-built tower or build the structure first (see the strawberry tower guide on this site for a DIY version).
- 2Set the tower in its final sunny location before filling — it gets heavy.
- 3Fill the bottom reservoir if the tower has one, and cap the fill hole to keep mosquitoes out.
- 4Add potting mix, firming lightly as you go.
- 5Plant one flower variety per pocket, tallest at the top. Safe edibles: nasturtium, viola, calendula, borage.
- 6Label each plant so you know what you're harvesting.
- 7Water from the top until it drains from the bottom. Top pockets dry first.
- 8Deadhead regularly and harvest blooms in the morning for the kitchen.
Tools needed
- ·Trowel
- ·Watering can with a narrow spout
Common mistakes to avoid
- ·Buying random nursery ornamentals and eating them — only eat flowers you grew clean and know are safe
- ·Not labeling plants — it's easy to forget which pocket is which
- ·Adding mystery flowers to the safe list: nasturtium, viola, calendula, and borage are reliable edibles; most others are not
- ·Planting all the same flower — mix heights and bloom times
- ·Overwatering — vertical towers drain fast but top pockets dry first
- ·No liner — soil washes out of pockets
- ·Top-heavy plants that flop over the sides
- ·Leaving a reservoir fill hole open — it becomes a mosquito nursery
Maintenance tips
Deadhead spent blooms to keep flowers coming. Harvest in the morning when petals are freshest. Feed with a balanced liquid fertilizer every 2 weeks. Water from the top until the bottom drips.
