How to Plan an Allotment Layout (Using Our Free Planner)

Welcome to the Free Allotment Planner

Planning an allotment properly can save time, prevent overcrowding, and dramatically improve your yields. In this guide, we’ll walk through how to design your layout step-by-step using our free interactive allotment planner, built specifically for UK growing conditions.

The planner uses a simple grid system inspired by square foot gardening, making it easy to design raised beds, organise crop rotation, and test companion planting combinations before anything goes into the ground. Whether you’re starting your first allotment or refining an established plot, this approach keeps your planning visual, practical, and efficient — with no logins, subscriptions, or hidden catches.

Before we begin the step‑by‑step walkthrough, you can open the tool in a new tab and follow along as you read.

Planning Your Allotment This Spring

If you’re planning your allotment this spring, this is usually the point where good ideas turn into workable allotment layouts. Early decisions around spacing, crop choice, and companion planting make the biggest difference later in the season, especially in small allotments or gardens where every square foot counts.

Rather than guessing or overcrowding beds, a visual allotment planner helps you see how everything fits before anything goes in the ground. As a result, you can start the season with a clear plan, avoid common beginner mistakes, and adjust your allotment layout easily as conditions change.

A Free Planner Built for Real UK Allotments

Not all garden planners are designed with UK allotments in mind. Many tools are built for large US backyards or require subscriptions before you can access useful features.

This planner was created specifically for raised beds, traditional allotment plots, and square foot gardening layouts common across the UK. It focuses on practical spacing, companion planting, and flexible grid sizing so you can design realistically for your own growing conditions.

There are no sign‑ups, no locked features, and no hidden tiers. You open it and start planning — simple as that. It’s designed to be practical first — simple enough for beginners, flexible enough for experienced growers.

What You Can Do with This Free Garden Planner

• Create custom layouts using the square foot garden planner UK method.
• Get instant companion planting feedback with the built-in companion planting app
• Plan anywhere — works on desktop, tablet, or mobile
• Start immediately — no sign-up, no tracking, no hidden catches (Revenue comes from Ads)

This isn’t another generic tool. It’s a genuine GrowVeg alternative, combining the ease of square foot gardening with allotment‑focused features — built by and for real UK growers.

Let’s Design Your Allotment Layout Step‑by‑Step

Now that you know what the planner can do, let’s walk through exactly how to use it. You can follow these steps while the tool is open in another tab, adjusting your layout as you go.

1: Select Your Plot Size

Use the Width and Height controls to match your growing space. Each square represents one square foot, making this ideal for square foot gardening layouts in the UK.

Whether you’re planning a compact raised bed or a full‑sized allotment, the grid adjusts instantly.

Tip: Use Generate Grid to rebuild the grid using new dimensions, use Clear to wipe all crops from the grid.

2: Choose and Place Your Vegetables

Browse the vegetable categories to explore everything from leafy greens to root crops.

Placement method (desktop & mobile)

1. Tap or click a vegetable to select it
2. Tap or click any grid square to place it
3. Continue tapping grid squares to place more of the same crop

This method works consistently across desktop, tablet, and mobile, with no dragging required.

Tip: Tap the same vegetable again, or use Cancel, to exit placement mode

3: Use Built‑In Companion Planting Feedback

As you design your layout, the planner automatically checks neighbouring crops and highlights relationships:

• Green border – good companions (grow well together)
• Red border – poor companions (best avoided)
• Amber border – mixed results (some benefits, some drawbacks)

On desktop, hover over highlighted squares for more detail. On mobile and tablet, simply tap a square to view companion planting insights.

These insights help you build a healthier, more productive allotment plan.

4: Select, Remove, and Adjust Crops

Desktop controls

• Right‑click a crop to remove it instantly

Note: The bottom selection bar is mobile‑only and does not appear on desktop.

Mobile & Tablet

• Tap a placed crop to select it
• A selection bar appears at the bottom of the screen
• Choose:
  • Remove – deletes the selected crop
  • Cancel – clears the selection without deleting

This prevents accidental removals and keeps controls within easy thumb reach.

5: Adjust and Refine Your Layout

You can experiment freely as you plan:

• Replace crops by placing a new vegetable over an existing square
• Clear the grid at any time to start again
• Switch between This Year and Next Year layouts to plan crop rotation

This flexibility makes it easy to test ideas and fine‑tune your allotment setup.

6: Export Your Layout (PNG or PDF)

Once you’re happy with your plan, you can save it for reference:

1. Click Export
2. Choose PNG (simple image) or PDF (print‑ready)
3. Your file downloads instantly

Open it on your phone while planting, or print it and take it to the allotment.

Tool Controls Summary

With these streamlined controls, the allotment planner stays fast, simple, and reliable — whether you’re planning at your desk or out in the garden.
