Biodynamic Planting Calendar UK
Use the Biodynamic Planting Calendar to see whether today is a Root, Leaf, Flower or Fruit day, then check which crops are actually in season to sow, plant or harvest in your region. Choose your location and date, or use the seven-day view to plan ahead.

How To Use The Biodynamic Calendar
1. Choose your country and region so normal growing conditions are taken into account.
2. Check today’s day type — Root, Leaf, Flower or Fruit.
3. Use Practical Jobs to see crops currently suited to that day.
4. Look ahead seven days if today’s category doesn’t suit what you want to grow.
Root, Leaf, Flower and Fruit Days
The biodynamic method divides days into four crop types based on the Moon’s position in the zodiac:
| Day | Commonly associated with |
|---|---|
| Root | Carrots, beetroot, onions and other crops grown mainly for roots/bulbs |
| Leaf | Lettuce, spinach, cabbage and leafy crops |
| Flower | Flowering crops, herbs and plants grown for blooms |
| Fruit | Tomatoes, beans, peas, courgettes and other fruiting crops |
The calendar works out the day’s biodynamic category automatically; the crop recommendations then narrow that down to plants that are actually in season.
How This Calendar Chooses Crops
A biodynamic day type on its own does not tell you whether a crop is sensible to sow in September, January or May. BYF combines the day’s Root, Leaf, Flower or Fruit classification with the same crop timing data used by our Garden Planner.
That means the recommendations are filtered by both biodynamic timing and ordinary seasonal growing conditions.
– Current date and selected region
– Normal sowing/planting/harvest windows
– Today’s biodynamic crop category
About the Biodynamic Calculations
The calendar uses the Moon’s position to determine its zodiac sign and associated element, which is then used to classify the date as a Root, Leaf, Flower or Fruit day. It calculates this automatically for the date you select and repeats the process for the next seven days, so you can see when the next suitable day type is coming up.
The crop suggestions then add a separate layer of practical growing data, filtering the results to crops that are actually in season for your selected region.
For a fuller explanation of the ideas behind these categories, see our Gardening by the Moon guide.
Frequently Asked Questions
The calendar above calculates whether the selected date is a Root, Leaf, Flower or Fruit day. It updates automatically when you change the date or move through the seven-day view.
Yes. Use the Previous, Today and Next controls, choose a specific date, or select one of the upcoming days in the seven-day outlook.
Yes. Your region is used when checking normal sowing, planting and harvesting windows, so the crop suggestions are not based on biodynamic timing alone.
A crop may be missing because it is not currently in season, does not have a suitable gardening action for that date, or belongs to a different Root, Leaf, Flower or Fruit category.
They are closely related, but not exactly the same. Biodynamic calendars use lunar and zodiac rhythms to divide days into Root, Leaf, Flower and Fruit periods. Our Gardening by the Moon guide explains the system in more detail.
Yes. The Biodynamic Calendar can help with when to sow, plant or harvest, while the free Allotment Planner helps you work out where crops will go and how much space they need.
