Lunar Gardening Calendar

This tool applies the traditional lunar-planting rule — above-ground crops during the waxing Moon (New to Full), root crops and bulbs during the waning Moon (Full to New) — to real, live phase data, so you can follow the traditional method without tracking the lunar calendar by hand.

This tool exists to automate the tradition, not to argue for it — for the actual evidence behind whether lunar timing affects yield at all, and the honest history of where the practice comes from, see this site's dedicated gardening-by-the-moon page. What this page gives you is simply the current phase-based recommendation, computed live, ready to apply (or ignore) as you see fit.

Whatever the science ultimately says, treating a lunar calendar as a planning rhythm — a fixed prompt to check on beds, prep soil, or start seeds — has a practical structuring value of its own, independent of anything the Moon's gravity is or isn't doing to your garden.

This tool computes the actual waxing/waning status live from real astronomical phase data, then applies the traditional rule automatically — useful whether you're genuinely trying the method or just curious what a lunar planting calendar would say for a specific date.

A more detailed version of the tradition splits the month into four windows rather than just two: New to First Quarter favors leafy above-ground crops specifically, First Quarter to Full favors fruiting above-ground crops (tomatoes, peppers, and similar), Full to Last Quarter favors root crops and bulbs, and Last Quarter to New is traditionally treated as a rest period for weeding, soil preparation, and pest control rather than planting. This tool's guidance below is based on the simpler two-window (waxing/waning) version, the more commonly cited rule.

Below is today's actual computed guidance under the traditional rule — a genuine, live reading rather than a generic example, useful as a reference point for what this tool's output looks like before its interactive date-selection form loads.

The tool's live waxing/waning determination comes directly from the same phase-angle calculation powering every other page on this site — not a static calendar lookup, meaning it stays accurate even in edge cases like a month with two full moons or an unusually short or long lunation.

If you want the more elaborate zodiac-sign-based version of this tradition (fruitful water signs, barren fire and air signs, semi-fruitful earth signs) rather than just the simple waxing/waning rule, several of this site's calendar pages note that month's full moon's specific sign classification alongside the basic guidance here.

A simple way to try this tool without any commitment: check it once a week for a full lunar cycle and jot down what it recommends each time, even if you're not actually planting anything — a quick way to see how the guidance shifts before deciding whether to apply it to real seeds.
