Free landscape design software can help you compare layouts before buying plants or materials. Some tools are genuinely free for an ongoing use; others provide a limited free version or a temporary trial. The eight options below distinguish those access models so you can choose a tool that fits both your project and your budget.
Access details were checked against the developers’ pages in October 2026. Features and plans can change, so check the linked page before committing time to a design. This is a comparison of documented capabilities and access, not a claim that each program has been hands-on tested.
1. GARDENA myGarden: a free garden-planning starting point
GARDENA myGarden is a free online planning tool. It suits a homeowner who wants to sketch a garden layout and explore the company’s planning tools without first buying a design package. Start with the plot outline and fixed features before adding beds or lawn areas. Its role as a manufacturer’s tool is worth remembering when exploring irrigation-related suggestions.
2. SketchUp Free: flexible browser-based modeling
SketchUp Free provides web-based 3D modeling for personal, noncommercial use. It is useful when the shape and relationship of structures matter more than a ready-made planting plan. Expect to spend time learning how to build and organize a model. Check the free plan’s import, export and storage limits rather than assuming it includes the paid desktop tools.
3. Sweet Home 3D: a free desktop download option
Sweet Home 3D offers free desktop downloads alongside paid store editions. It is primarily a home-design application, so consider it for planning the relationship between a house, doors, furniture and adjacent outdoor space. Review the available object libraries before choosing it for detailed planting work. Follow the official download links and distinguish the free installer from a paid app-store version.
4. iScape: limited free access for visual concepts
iScape’s FAQ describes free download and limited trial access, with premium subscriptions for broader features and its full database. It can help visualize changes using a photograph of an existing space. A photo-based concept is useful for discussing color, mass and placement, but do not treat a convincing image as a measured construction drawing. Confirm which features remain available without payment.
5. Realtime Landscaping: a trial of paid software
Realtime Landscaping offers a free trial rather than an unrestricted free product. Explore the trial limitations and system requirements before investing in a detailed model. It is an option to evaluate when you want a dedicated landscape-design package and are prepared to purchase software if it suits the project.
6. SmartDraw: a short trial for drawing plans
SmartDraw’s landscape-design page advertises a seven-day trial. Treat it as a paid diagramming product you can test, not as permanently free landscape software. It may suit a clear overhead layout for discussing paths, beds and furniture. Before the trial ends, check export access and the subscription terms that apply to your account.
7. Garden Planner: a time-limited desktop trial
Garden Planner offers a fifteen-day trial followed by a paid license. Its garden-layout focus can be appealing when you want to arrange plants and objects on a plan without building a detailed architectural model. Read the current trial restrictions and check the operating-system requirements before downloading.
8. VizTerra: professional software to evaluate
VizTerra is a landscape-design product from Structure Studios with trial access and paid subscription arrangements. Review the developer’s current plan comparison, including fees and requirements. It is more relevant to someone evaluating an ongoing design workflow than to a homeowner who only needs a quick free sketch.
Choose by the output you need
- A simple layout: start with an overhead planner and measured dimensions.
- A visual before-and-after: consider photo-based design, while keeping a separate measured plan.
- Three-dimensional spaces: allow time to learn modeling and verify the export format you need.
- A professional workflow: compare licensing, collaboration, libraries and hardware requirements before subscribing.
Make the design useful before making it elaborate
Measure the site and mark doors, existing trees, utilities, slopes and areas that must remain accessible. Test one small design and export it before committing the whole project to a tool. This reveals whether the free version or trial actually supports your intended output.
Use repetition to bring unity to a planting scheme, balance large visual masses, and reserve strong color or contrast for a few focal points. Repeat forms to create rhythm along a path, but leave room for plants at maturity. These design choices matter more than filling every empty area with objects from a library.
Keep the concept separate from structural, drainage, utility and permitting decisions. A software plan does not verify a boundary, locate buried services or establish that a retaining wall is safe to build. Use the finished concept to communicate your aims, then obtain the necessary site-specific advice.
