Thirteen free tools, grouped by what you're trying to do: work out timing, measure what you're building, plan the plot, or figure out what and which to grow. No account, nothing to install.
Timing
The single most useful number for Scottish growing. Enter your region and get your local last spring frost and first autumn frost: every sowing date here flows from these two numbers.
A month-by-month view of what to sow, plant and harvest in Scotland, or switch to a printable checklist for the current month. Built from real timing data, adjusted for Scottish regions.
Checks the standard UK sow/plant/harvest timing against your region's actual frost dates, so you can see whether it genuinely fits where you garden.
Measuring & calculating
See exactly how far apart your seeds and plants need to go. Spacing is a disease control as well as a yield decision: crowding invites botrytis, mildew and blight.
A lime calculator, not a pH encyclopedia: tells you how much to add for your soil type and what you're growing, and flags the crops that don't want it at all.
Measure your bed and get its area, plus how much compost or well-rotted manure it needs, dug in or as a mulch, from real, sourced application rates.
Planning your plot
A visual four-bed rotation planner. The simplest way to keep your soil healthy and break pest and disease cycles without a spreadsheet.
Draw your plot to scale, put beds and crops in it, and print the result. Every bed shows what it holds, when each crop goes in, and the months it sits empty.
Choosing & diagnosing
Every common gardening claim checked against the evidence, for a crop, a pest or a beneficial insect. Companion planting, slug remedies, the lot: find out what holds up, what does not, and what the sources argue over.
Works the other way round from the rest of this section: tell it your sun, space, frost protection and difficulty level, and see which of the 87 crops actually fit your garden.
You've already picked the crop — this picks the variety. A couple of quick questions about your situation, one recommendation, sourced from the site's own Best Varieties comparisons. Covers 80 crops.
Something's wrong with a plant and you don't know what. Pick the crop, where the damage is and what it looks like, and get a ranked shortlist of likely causes from the site's own 85-entry pest library, not a single guess.
