How to make a planting plan for your yard

Start with a base map of the real space. It can be graph paper, a printed photo, or a simple digital sketch. Mark the bed edges, doors, windows, downspouts, utilities, paths, existing plants, slopes, and the places you need to reach for maintenance. Measure the widest and narrowest parts instead of treating an irregular bed as a perfect rectangle.^{1Source 1Drawing a Landscape Plan: The Base MapUniversity of Florida IFAS Extension}

Add the plants you are keeping at their approximate mature canopy size. This often changes the available area more than expected. A young tree may cast a small shadow today but occupy a much larger part of the plan later.

Only then draw new plants as circles or loose masses at mature width. You are not trying to make botanical art. Check whether the groups look connected, whether plants will collide with the house or path, and whether you can still step in to maintain them.^{2Source 2Home Landscape DesignMississippi State University Extension,4Source 4Landscape Design with Plants: Creating Outdoor RoomsUniversity of Florida IFAS Extension}

If a plant is listed for 24-inch on-center spacing, place the centers about 2 feet apart. A 12-foot run divided by 2 feet suggests roughly six plants as a first estimate. That is not an automatic order quantity. The bed may curve, the group may be split, and each end needs a sensible setback.^{2Source 2Home Landscape DesignMississippi State University Extension,3Source 3North Carolina Coastal Landscaping DesignsNorth Carolina Sea Grant}

Draw the mature circles before settling the count. If six circles form an awkward row, five arranged as a loose group of three and two may produce a better mass. If the named variety spreads 3 feet rather than 2, the count should fall. Buying more small pots does not change the mature math.^{2Source 2Home Landscape DesignMississippi State University Extension,4Source 4Landscape Design with Plants: Creating Outdoor RoomsUniversity of Florida IFAS ExtensionaNote aThe pot size describes what you are buying today. Mature spread determines how many plants the bed can hold.}

Add a note about direct sun, soil that stays wet or dries quickly, and your watering setup. On each plant-list line, record the exact name if you have one, its job in the bed, draft quantity, and maximum mature height and width. A saved image of the plant label helps when two varieties have similar names.

Start the conversation with the hardest constraint: ‘I need a repeated flowering edge that stays off this path. Here is the space, light, and watering it will get.’ Then ask which available plants fit. That gives staff more to work with than a picture of flowers you like.
