Garden moon calendar: how to read this page

Favourable days for planting and care

Fertile signs and waxing lunar segments are highlighted as especially useful for planning, sowing, and routine garden work.

Caution in weaker windows

New Moon and certain signs are treated more carefully. When a day is split into segments, trust the coloured intervals more than the date alone.

Why location matters

In-day transition times depend on place. Map and coordinates adapt the garden calendar to your region.

Using the garden calendar for September 2025

For sowing and upkeep

Start from favourable segments — they are more informative than a single daily label when transitions happen mid-day.

For regional calculation

With location data the worker can compute the same month for another area and show local transitions more accurately.

For past months

Archive navigation helps compare older months and seasonal patterns.

Fruit, root, flower, and leaf days

In the biodynamic tradition (Maria Thun) the moon sign assigns each day a plant part. Use it to time sowing, care, and harvest more precisely.

Fruit days — fire signs ♈ Aries · ♌ Leo · ♐ Sagittarius

Best for fruit and seed crops: tomatoes, cucumbers, zucchini, beans, peas, pumpkin, corn. Also good for harvesting fruit and seed for storage.

Root days — earth signs ♉ Taurus · ♍ Virgo · ♑ Capricorn

Best for root crops: carrots, radishes, beetroot, potatoes, onions, celeriac. Good days for hoeing, mulching, fertilising, and harvesting roots for storage.

Flower days — air signs ♊ Gemini · ♎ Libra · ♒ Aquarius

Best for flowering plants: roses, sunflowers, lavender, cut flowers, plus broccoli and cauliflower. Also for cutting flowers for tea and dried bouquets.

Leaf days — water signs ♋ Cancer · ♏ Scorpio · ♓ Pisces

Best for leafy crops: lettuce, spinach, cabbage, chard, parsley, chives, herbs. Recommended for watering and leaf care; less suitable for harvesting for long storage.

Note

The garden moon calendar is astrological planning guidance. Weather, soil, season, and practical garden conditions remain decisive.

FAQ

Why are some signs treated as fertile?

In this editorial logic certain signs are traditionally linked with growth, care, and better rooting.

Why is a whole day not always one label?

If lunar day or sign changes during the day, the calendar shows several real windows instead of one daily average.
