What is the difference between the "Relative to last frost" and "Temperature-based" calendars?

"Relative to last frost" is the classic way to plan growing. Each plant has a number of weeks before or after the last spring frost indicating when you can sow, transplant or direct sow.

"Temperature-based" is often more accurate. It is based on what temperature each plant needs and compares with historical statistics for your location.

Can I add a custom plant to the calendar?

Yes. Search for your plant in the search field. If you cannot find it among our plants, you can choose to add it as a custom plant with your own dates.

Can I adjust suggested dates in the calendar for a plant?

Yes. Click the edit button on the plant's row in the calendar. You can then adjust dates for starting indoors, transplanting and direct sowing.

How are calendar dates calculated?

Dates are calculated from local frost and temperature thresholds based on 20 years of measurement data. They are continuously adjusted during the season based on current weather forecasts.

Why do the dates differ from other growing guides?

Many guides use general zones or regions. Hortuli uses exact data for your location instead, which can give different results. Microclimate, wind exposure, soil type and sheltered positions can make a big difference.

Are the dates always correct?

No. Our calculations are based on historical statistics and weather forecasts, and local conditions can vary.
