What is biodynamic planting?

Biodynamic growers work with the lunar calendar to choose the best days for each type of garden task. Root days favour root vegetables and root herbs. Flower days bring out the best in flowering plants. Leaf days suit leafy crops and foliage. Fruit days are ideal for anything grown for its seed or fruit.

The moon's position in the zodiac determines the day type, and its phase - waxing or waning - influences whether your plants are putting energy into growth or consolidation. When you align your sowing and harvesting with these rhythms, you're working with the plant's own timing rather than against it.

I've been growing medicinal herbs this way for many years. This calendar is the tool I always wanted but couldn't find.

What's in the calendar

🌙 Moon Calendar

A full monthly view with every day colour-coded by biodynamic type - root, flower, leaf, or fruit. Moon phase and zodiac sign shown for each date. Navigate month by month, print if you need a physical copy..

🌿 Plant Guide

Detailed growing profiles for 53 herbs and vegetables. Each entry covers the best biodynamic days for sowing and harvesting, sow windows, harvest timing, soil and sun requirements, growth habit, and medicinal or culinary use.

☉ Today's Tasks

The app opens here. Today's date, today's moon phase, today's day type and the specific plants that are best worked with right now. No searching, no cross-referencing. Just open it and go.

📅 Seasonal Timeline

A year-at-a-glance view showing the full growing arc of every plant across all twelve months, useful for planning successions and understanding the rhythm of the year as a whole.

☀️🌙 Day and Night Display

Toggle between a deep teal dark mode, easy on the eyes in the evening or in low light, and a clean white light mode for bright conditions or daytime use. The app remembers your preference.

Two free tools included

Both are browser-based and work on any device. No installation, no additional accounts.

Lunar Phase Tracker

A simple, focused tool for tracking the moon day by day. It shows the current phase, where you are in the lunar cycle, and gives you a clean at-a-glance view of the month. Useful as a daily reference, or as a quieter companion to the full biodynamic calendar on days when that's all you need.

Companion Planting & Crop Rotation Helper

Good companions make a real difference - to pest pressure, soil health, and how plants use space. This tool lets you select any herb or vegetable and see instantly what grows well alongside it, what to keep it away from, and how to rotate it through your beds year to year. Covers both medicinal herbs and vegetables, and works directly alongside the planting calendar.

Why perpetual is important

Most planting calendars expire. You buy a new one every January, and what you learned from last year's is locked in a book you've already recycled.

This calendar never expires. The astronomical calculations run in real time, so it's as accurate in five years as it is today. Pay once and use it for every growing season from here on. The two companion tools come with it at no extra cost.

At €19 it costs less than one printed calendar - and after the first year, it's already paid for itself.

If you grow herbs and vegetables at home and want to do it better.

This is for people who grow medicinal herbs and want to bring more intention to that practice. It works just as well for vegetable growers. You don't need prior knowledge of biodynamics - the app explains everything as you use it - but if you're already familiar with the principles, you'll find the depth here that most tools don't offer.

🌱 You do not need any background in astrology or biodynamics to use this calendar. If you can read a date, you can use it.

A note on the tradition behind this calendar

The biodynamic growing calendar is rooted in the work of Austrian philosopher and scientist Rudolf Steiner, who first articulated the principles of biodynamic agriculture in 1924, and was developed into practical planting guidance by German researcher Maria Thun, who spent decades observing and documenting the relationship between moon cycles and plant growth. Their work built on millennia of traditional knowledge: from the Roman agricultural writers who advised sowing by the moon, to indigenous traditions such as the Maori Maramataka, which mapped planting and harvesting across the full lunar year. This calendar draws from that long lineage and brings it into a form that works for the modern home grower.

Frequently asked questions

Do I need to know astrology to use this?

Not at all. The calendar does all the calculation for you. All you need to do is check the day type and follow the guidance.

Is this based on real astronomical data?

Yes. The calendar uses the Meeus astronomical algorithm to calculate the moon's actual position in the zodiac in real time. It is accurate and updates every day automatically.

Does it work for my climate?

The sowing and harvest windows in the Plant Guide are calibrated for a temperate Northern Hemisphere climate. If you are gardening in a different region, you may need to adjust the seasonal timing, but the biodynamic day types and moon phases apply universally.

Does it work on my phone?

Yes. The calendar is fully responsive and works on any smartphone, tablet or desktop browser. No download or app installation is needed.

Is this a subscription?

No. It is a one-time purchase with permanent access. There is no renewal fee and no expiry date.
