A small-vase zinnia bed

Your current measurements below control the estimate. The original assumptions remain available here so you can see what changed.

Original setup assumptions

Inside bed dimensions: 8 × 3 feet, a 12-inch target fill and no existing mix entered. Change the inputs for your frame and current soil.
The named example is Zinnia ‘Magellan Coral F1’. Its AAS record lists 18-inch garden spacing; a grid with 9-inch edge clearance fits 10 positions here.
This is a compact plant for small vases, not a promise of long florist stems. Confirm the cultivar, local warm-season timing, sun and harvest access.

1 / Choose the growing spaceProject name

Identical bedsInside length (feet)Inside width (feet)Target fill depth (inches)Existing fill depth (inches)Extra volume allowance (%)Chosen bag size (cubic feet)

Use inside measurements. Containers are estimated as tapered round vessels; irregular shapes need a measured capacity. Bag sizes come from your chosen package label.

2 / Match plants to the space

Direct sunlight (hours per day)Main planting goal

Check your exact plant reference. Herbs, flowers and houseplants have very different light needs.

Find a plant and its care requirements →Estimate a uniform planting grid

Between plants in a row (inches)Between rows (inches)Clearance to each bed edge (inches)

Enter spacing for your selected cultivar and training method. The defaults are geometry examples, not a crop recommendation. Mixed planting and access aisles are not included.

3 / Plan water deliveryInclude a drip delivery estimate

Start with a reachable water source. Add drip calculations when you know the layout and outlet specification.

4 / Keep the project togetherConfirm inside measurements and accessChoose suitable growing mix and verify bag volumeCheck plant variety, local timing and mature sizeAllow space for supports and harvestingConfirm the water source and component connectionsCheck drainage, surface protection and filled weightProject notes

Your materials estimate

16bags of growing mix

24 cubic feet, using 1.5 cu ft bags.

Growing spaces: 1 beds
Interior bed area: 24 sq ft total
Geometric planting positions: 10 total · 10 per bed

Rounded up to full bags. This estimate excludes shipping, price, compaction and materials already on hand except the existing fill you entered.

One bed, viewed from above

2 rows of 5 positions in one bed. 1 identical bed in the project. Dots mark centers, not mature plant size. Access paths and support footprints are not drawn.

Materials and remaining choices

Quantities follow your current inputs. Check what you already own; unmeasured items remain decisions to make.

Bed spaces ↗: 1
8 × 3 ft inside each; confirm the frame, base and working access.
New growing mix ↗: 16 bags
24 cu ft estimated at 1.5 cu ft per bag; includes your entered allowance.
Planting positions to review ↗: 10
2 rows × 5 positions per row in each bed. Geometry does not account for cultivar spread, supports or paths.
Water access ↗: Measure your route
Confirm a reachable source and a hose or watering can that suits the distance. Set watering from the mix, roots and weather.
Protection and supports ↗: Decide before planting
Check local pest pressure, the plant’s mature habit and harvest access. No universal support or protection kit is included.

How the planner works

Bed volume uses inside length × width × the difference between target and existing fill depth, multiplied by bed count and your allowance. Round-container volume uses the filled portion of a truncated cone, subtracts your root-ball volume and multiplies by container count. Bags are rounded upward. Grid positions use your row spacing and edge clearance. Drip time divides your chosen water target by total rated outlet flow.
