Beds01
Rectangular Bed Area
A measured bed area anchors soil, mulch and planting estimates.
Open calculator ↗Beds02
Circular Bed Area
A circular bed's footprint depends on the square of its diameter.
Open calculator ↗Beds03
Triangular Bed Area
Triangular corners can be included in a garden plan by measuring a base and its perpendicular height.
Open calculator ↗Soil04
Raised Bed Soil Volume
A raised bed behaves like a shallow box for a first soil-volume estimate.
Open calculator ↗Soil05
Soil Bag Count
Bag volume translates the planned fill into a whole-bag purchase.
Open calculator ↗Containers06
Cylindrical Pot Volume
A straight-sided round container can be estimated as a cylinder.
Open calculator ↗Containers07
Tapered Pot Volume
A linearly tapered round pot resembles a conical frustum.
Open calculator ↗Containers08
Rectangular Planter Volume
A rectangular planter volume helps estimate how much growing medium to prepare.
Open calculator ↗Soil09
Mulch Volume
Mulch demand follows the area to cover and the chosen layer depth.
Open calculator ↗Soil10
Mulch Bag Count
Whole-bag purchasing rounds the volume requirement upward.
Open calculator ↗Soil11
Compost Top-Dressing Volume
A thin top-dressing can be planned separately from the full bed fill.
Open calculator ↗Soil12
Compost Share of Mix
A volume-based mix ratio assigns part of a batch to compost.
Open calculator ↗Soil13
Soil Mix Remainder
Subtracting known components preserves the target batch volume in a simple additive recipe.
Open calculator ↗Plant spacing14
Grid Plant Count
A square grid estimates planting positions by fitting equal spacing cells into a rectangular bed.
Open calculator ↗Plant spacing15
Rectangular Spacing Count
Different in-row and between-row spacing allows a row-based planting estimate.
Open calculator ↗Plant spacing16
Plants per Row
A spacing-cell convention allocates one plant per complete segment along the row.
Open calculator ↗Plant spacing17
Row Count
The bed width divided into row-spacing cells gives a consistent row count.
Open calculator ↗Plant spacing18
Row Length for Plant Count
Working backward from plant count estimates row length including two half-spacing edge margins.
Open calculator ↗Seeds19
Seeds for Expected Germination
A germination rate converts the desired average seedling count into a sowing estimate.
Open calculator ↗Seeds20
Expected Seedlings
The expected seedling count combines seed number with a germination fraction.
Open calculator ↗Seeds21
Seed Packet Count
Packet counts turn a seed plan into whole purchase units.
Open calculator ↗Seeds22
Tray Count
A cell tray plan assigns one target seedling to each available cell.
Open calculator ↗Seeds23
Tray Growing Medium
Cell volume and tray count determine the total medium to prepare.
Open calculator ↗Seeds24
Succession Sowing Batches
Counting a sowing at day zero and at each full interval gives the number of scheduled batches.
Open calculator ↗Water25
Water Volume from Depth
One millimetre spread over one square metre equals one litre, linking irrigation depth and volume.
Open calculator ↗Water26
Watering Depth from Volume
An applied volume can be expressed as an equivalent uniform depth.
Open calculator ↗Water27
Hose Runtime
A bucket-tested flow rate translates a water-volume target into hose runtime.
Open calculator ↗Water28
Bucket-Test Flow Rate
Timing a known bucket volume provides a practical flow measurement.
Open calculator ↗Water29
Drip Zone Flow
Emitter count and rated flow estimate the demand of a drip zone.
Open calculator ↗Water30
Drip Irrigation Runtime
Dividing a volume target by zone flow gives a first runtime estimate.
Open calculator ↗Water31
Rain Capture Volume
Catchment area and rainfall depth estimate potential collection after an efficiency allowance.
Open calculator ↗Water32
Rain Tank Fill Share
Comparing collected volume to tank capacity shows how much storage it represents.
Open calculator ↗Water33
Tank Supply Duration
A steady daily demand converts stored water into a simple duration estimate.
Open calculator ↗Water34
Weekly Watering Total
Summing equal watering sessions makes a weekly consumption record easier to compare.
Open calculator ↗Water35
Measured Irrigation Efficiency
Measured retained water compared with applied water describes a defined efficiency estimate.
Open calculator ↗Layout36
Bed Edging Length
A rectangular bed perimeter gives the total edging run.
Open calculator ↗Layout37
Circular Edging Length
A circular border's length follows its circumference.
Open calculator ↗Layout38
Garden Path Gravel
A straight uniform path uses rectangular-layer geometry.
Open calculator ↗Layout39
Landscape Fabric Roll Length
An area-based roll estimate includes a user-entered allowance for overlaps and cuts.
Open calculator ↗Layout40
Plant Label Count
A labeling plan keeps repeated rows and spare labels visible in one count.
Open calculator ↗Layout41
Support Twine Length
Repeated support lines can be totalled before adding an allowance for ties.
Open calculator ↗Records42
Harvest per Plant
An average per-plant harvest helps compare your own recorded batches.
Open calculator ↗Records43
Harvest per Area
Area-normalized harvest makes differently sized plots easier to compare.
Open calculator ↗Records44
Seedling Survival Rate
A survival rate records the share of transplanted plants still present at a chosen checkpoint.
Open calculator ↗Records45
Water per Harvest Mass
Irrigation divided by harvested mass offers a simple record-based comparison.
Open calculator ↗Records46
Growing Degree Day Simple
A simple growing-degree-day value accumulates warmth above a chosen base temperature.
Open calculator ↗Records47
Average Daily Harvest
A daily average summarizes production across a recorded interval.
Open calculator ↗Units48
Garden Area in Square Feet
Area conversion helps compare garden plans that use different unit systems.
