Biodynamic Planting Calendar – Free UK & US Lunar Gardening App
The Backyard Farmer Biodynamic Planting Calendar helps you time sowing and planting according to traditional lunar gardening principles. Based on fruit, leaf, root and flower days, this free tool shows you what type of crops are best planted today — tailored for the UK and US. Whether you follow biodynamic methods strictly or simply want to experiment with lunar timing, this calendar makes it practical and easy to apply.
How The Biodynamic Planting Calendar Works
The biodynamic method divides days into four crop types based on the moon’s position in the zodiac:
Fruit days – Best for tomatoes, beans, peas, squash and fruiting crops
Root days – Ideal for carrots, beetroot, onions and potatoes
Leaf days – Favour leafy greens like lettuce, spinach and cabbage
Flower days – Good for brassicas, broccoli and flowering crops
This tool automatically calculates today’s lunar influence and shows you what category the day falls into.
No charts. No complicated tables. Just clear guidance.

- Adjusts for UK and US locations
- Shows the next 10 days at a glance
- Recommends crops suitable for the current day
- Integrates with Backyard Farmer growing guides

Who Is This For?
This calendar is ideal if you:
- Grow on an allotment
- Follow organic or regenerative methods
- Are curious about lunar gardening
- Want to experiment without committing fully
- Prefer simple, practical tools
You don’t need to be strictly biodynamic to benefit from better timing.
Does Lunar Gardening Actually Work?
Biodynamic gardening is based on the idea that plant growth is influenced by lunar cycles, much like tides.
While scientific evidence is mixed, many growers report:
- Stronger germination
- More vigorous growth
- Improved crop quality
At worst, it encourages more mindful timing. At best, it gives you an edge.
Frequently Asked Questions

No. Many gardeners use lunar planting as a simple timing guide alongside traditional seasonal advice. You can combine it with standard UK planting calendars, soil temperature checks and your own experience.
Scientific evidence is mixed. However, many growers report improved germination, stronger growth and better crop quality when they align sowing with favourable lunar days. At the very least, it encourages more mindful and structured planting.
