A site diagram is one of the most practical tools a gardener can create. It does not need to be technically perfect — it needs to accurately represent your property and give you a reliable reference for planning. A good diagram lets you see the whole property at once, identify relationships between spaces, and make decisions on paper before any digging begins.

Why draw a diagram

• Experiment on paper — test layouts and ideas before committing to changes in the ground
• Identify problems early — spot drainage issues, shade conflicts, and awkward circulation before they become expensive mistakes
• Communicate plans — share your vision clearly with contractors, family members, or garden helpers
• Keep a record — document what exists and what has been added over time as the garden evolves
• Plan in phases — return to the diagram season after season as priorities and resources change

Tools and materials

Hand drawing

item	notes
Graph paper	Quarter-inch or half-inch grid works well for most residential lots
Ruler or straightedge	Essential for clean, accurate lines
Pencil and eraser	Always draw in pencil first
Measuring tape	At least 25 ft; 100 ft preferred for larger properties
Compass or phone app	For determining true north
Colored pencils	Useful for distinguishing sun, shade, drainage, and proposed areas

Digital tools

item	notes
Procreate (iPad)	Freehand drawing with layers; ideal for separating base map from proposals
iScape	Landscape-specific app; place plants and structures on a property photo
Home Outside	Simple residential landscape planning tool
Google Earth Pro	Measure distances on satellite imagery; export scaled base maps
County GIS Viewer	Provides parcel boundaries and aerial imagery for your specific property

Establishing a scale

Choose a scale that fits your paper size and property dimensions. Write the scale clearly on every drawing so it can be referenced later.

• 1 in = 10 ft — best for small yards or individual garden areas drawn in detail
• 1 in = 20 ft — good for average residential lots and typical home gardens
• 1 in = 40 ft — better for large properties; use alongside zone maps and detail drawings

For large properties, draw the full site at a smaller scale for overall planning, then create separate larger-scale drawings for specific areas such as the kitchen garden, front entrance, or a particular planting bed.

Taking measurements

House

What to Measure	Notes
Overall footprint	Measure the full length and width of the house
All doors	Note location and which direction each door opens
All windows	Note location and which room each window belongs to
Distance to property lines	Measure from the house to the nearest property line on all four sides

Grounds

What to Measure	Notes
Property dimensions	Overall lot size and boundary lengths on all sides
Outbuildings and structures	Location and dimensions of sheds, barns, garages, and other buildings
Driveways and paths	Location, width, and surface type of all paved or worn paths
Fences, walls, and hedges	Location, length, and approximate height
Significant trees	Trunk location and canopy spread; note species if known
Shrubs and existing plantings	Location and approximate spread of established shrub masses and beds
Utility meters and spigots	Location of HVAC equipment, electrical meters, and outdoor water sources
Underground utilities	Location of buried lines, septic systems, and drain fields
Slopes and drainage features	Direction of slope, low spots, swales, and areas of standing water
Existing garden beds	Location, shape, and approximate dimensions

What to Include on the diagram

Layer	Elements
Base Map	Property boundaries and dimensions; house footprint with doors and windows; all outbuildings and structures; driveways and paved surfaces
Base Map	Established trees with canopy spread; shrubs and hedgerows; fences, walls, and gates; utility lines, meters, and easements; septic and drain field; wells or water features
Site Conditions	North arrow; areas of full sun, part shade, and full shade; prevailing wind direction; drainage patterns; frost pocket locations; slopes with flow direction
Proposed Elements	New garden beds with dimensions; new paths or walkways; proposed trees or shrubs; fencing or screening; structures such as greenhouse or cold frame; water features or rain gardens; compost and utility areas

Drawing the diagram – Step by step

1. Gather your measurements — walk the property with a measuring tape and notepad; record everything before sitting down to draw; take more measurements than you think you need
2. Establish your scale — choose a scale that fits your paper and property; mark it clearly on the drawing before adding any features
3. Draw the property boundaries — start with the outer edges of the lot; draw all boundary lines to scale and label dimensions on each side
4. Place the house — measure from two adjacent property lines; draw the footprint to scale in the correct position; mark all doors and windows
5. Add fixed structures and features — add the driveway, outbuildings, fences, paths, and other hard features; verify measurements as you go
6. Add trees and existing plantings — draw trees as circles showing canopy spread with a dot at the trunk center; label by species if known; add shrub masses and existing beds
7. Add site condition notations — draw a north arrow; note sun and shade areas, drainage patterns, wind direction, slopes, frost pockets, and other observed conditions
8. Review and refine — step back and look at the drawing as a whole; walk the property with the diagram in hand to verify that what is on paper matches what is on the ground

Planning for large properties

A single diagram may not capture enough detail for a large piece of property. Consider a layered approach using multiple drawings at different scales.

• Whole property overview — small scale; shows general layout, land use areas, and major features
• House and immediate grounds — medium scale; entry, foundation plantings, patios, and close-in beds
• Kitchen garden area — larger scale; bed layout, paths, cold frames, compost, and water access
• Orchard or food forest — medium scale; tree placement, spacing, and understory plantings
• Meadow or naturalized area — small to medium scale; mowing patterns, paths, and planting zones
• Woodland

Digital tool options

• Procreate (iPad) — freehand drawing with layers; separate base map from proposed changes; excellent for creative, iterative planning
• iScape — landscape design app for homeowners; place plants and structures directly onto a photo of your property
• Home Outside — simple digital planning tool designed specifically for residential landscape planning
• RoomSketcher / Planner 5D — interior-focused but adaptable for outdoor spaces and courtyard areas
• Google Earth Pro — measure distances on satellite imagery; export scaled images to use as a base map
• County GIS Parcel Viewer — provides property boundaries and aerial imagery specific to your parcel; free and publicly available

Elements and key points

element	key point
Scale	Choose a consistent scale and mark it clearly on every drawing
Measurements	Measure everything before drawing; use triangulation for off-axis features
Base Map	All fixed features of the property — structures, trees, utilities, boundaries
Site Conditions	Sun, shade, drainage, wind, slope, and frost pockets noted directly on the drawing
Proposed Changes	Drawn on a separate layer or copy so the base map stays clean
Large properties	Use multiple drawings at different scales — overview, zone maps, and detail drawings
Updates	Return to the diagram regularly as the garden grows and changes over time

The time invested in careful site diagrams pays dividends throughout the life of the grounds. It becomes the map from which all other planning decisions are made — and a record of how the land and the gardens have grown together over the years.
