Practical, no-nonsense garden tools for every UK grower — window box or full allotment. Free, forever.
Practical advice for UK growers — what to plant, when to plant it and how to fix common problems.
Companion planting is the practice of growing certain plants close together to improve growth, deter pests, and make better use of space. Classic UK combinations include growing basil alongside tomatoes to repel aphids, planting marigolds around brassicas to deter whitefly, and growing carrots and leeks together to confuse each other's main pests. Our companion planting checker covers 26 common UK vegetables, herbs and flowers with full friends and foes guides for each.
UK growing conditions vary significantly from Scotland to Cornwall — frost dates, rainfall and growing seasons all differ by region. GrowGuide's tools are built specifically for UK growers, with regional frost date data for 11 UK regions, a monthly jobs checklist tailored to where you are in the country, and sowing and harvest timelines based on UK seasons rather than American or European calendars.
The pest and disease identifier helps you diagnose problems by symptom — yellowing leaves, holes in foliage, white powder, wilting, or distorted growth — and suggests organic and conventional treatments for each. Common UK garden problems covered include slugs and snails, aphids, vine weevil, blight, powdery mildew, club root and more.
The veg patch planner lets you lay out raised beds and allotment rows with a drag-and-drop grid, with live companion planting warnings when incompatible plants end up next to each other. The seed-to-harvest timeline tool covers 35 plants with week-by-week growth stages, sowing calendars and succession planting advice — so you can stagger harvests and avoid a glut.
