Red-leaf hibiscus (Hibiscus acetosella) Plant Spacing Calculator
Hibiscus acetosella
Start with the source-backed 18-inch spacing default, then enter your bed length and width to calculate an approximate plant count, seeds or starts needed, and the spacing used. Defaults are editable so your variety and growing system can take priority.
Quick spacing answer
How far apart should you plant red-leaf hibiscus (hibiscus acetosella)?
Start with 18 inches between plants using a intensive bed layout. The dataset does not provide a separate supported range, so only the sourced default is shown.

Red-leaf hibiscus (Hibiscus acetosella) spacing chart
These values come from the existing crop record. The density column is derived planning math and does not add a new horticultural recommendation.
| Context | Spacing | Geometric plants/sq ft |
|---|---|---|
| Dataset default | 18″ | 0.4 |
Plants per square foot is transparent square-grid planning math (144 ÷ spacing²), not an extension-service recommendation or a guarantee of field performance.
Red-leaf hibiscus (Hibiscus acetosella) in raised beds
Enter the raised bed's actual length and width in the calculator. It applies the selected spacing and intensive bed model to estimate how many planting positions fit; it does not assume a crop-specific raised-bed recommendation that is absent from the source data.
Red-leaf hibiscus (Hibiscus acetosella) per square foot
At 18″ spacing, square-grid geometry equals approximately 0.4 plants per square foot. This is a geometric planning estimate based on the displayed spacing—not an agronomic guarantee. The calculator may use a different documented model for intensive bed layouts.
Why red-leaf hibiscus (hibiscus acetosella) spacing changes
Variety, production system, support, and planting layout can change usable spacing. Plantometry keeps the sourced default editable and shows a range only when the crop record supports one.
How many red-leaf hibiscus (hibiscus acetosella) plants fit in my bed?
Use the calculator above with your bed dimensions. The result shows the approximate plant count, the spacing used, and seeds or planting material to prepare where appropriate.

Planning notes
- Landscape fabric
Cut-and-come-again. A planting keeps producing new stems over a relatively long harvest period when it is picked regularly, so successive plantings are usually spaced farther apart.
- Landscape fabric is commonly used for spacing and weed control.
